World War II: The Defensive Phase


About one o'clock in Washington on the afternoon of December 7, l941, the first news of the Japanese attack on Pearl Harbor, Hawaii, reached the War Department. The news came as a shock, even as the attack itself had come. It caught by surprise not only the American people at large, who learned of the attack a short while later, but also their leaders, including the very officers who had earlier been so much concerned over the possibility of just such an attack. One explanation is that these officers and their political superiors were momentarily expecting the Japanese to use all their forces against weakly held British and Dutch positions in the Far East (and probably, but not certainly, against the Philippines). But without warning in the early morning of December 7, powerful carrier-borne air forces had smashed the U.S. Pacific Fleet at anchor in Pearl Harbor. The same day (December 8 in the Philippines), about noon, Formosa-based bombers caught the bulk of the U.S. Far East Air Force lined up on Clark and Iba fields not far from Manila in central Luzon and virtually destroyed it. For the second time within a quarter-century, Americans found themselves fully involved in a war they had not sought—this time in the first truly global conflict.


The Outbreak of War: Action and Reaction


The attack on Pearl Harbor was one of the most brilliant tactical feats of the war. From 6 carriers which had advanced undetected to a position 200 miles north of Oahu, some 350 aircraft came in through the morning mist, achieving complete tactical surprise. They bombed and strafed the neatly aligned Army planes on Hickam and Wheeler Fields, as well as Navy and Marine Corps aircraft, and they carefully singled out as targets major units of the Navy's battle force at anchor in the harbor. Fortunately, the fleet's 3 carriers were away at the time, and the attackers failed to hit the oil tanks and naval repair shops on shore. But the blow was devastating enough. About 170 aircraft were destroyed and 102 damaged, all 8 battleships were sunk or badly damaged, besides many other vessels, and total casualties came to about 3,400, including 2,402 service




men and civilians killed. Japanese losses were about 49 aircraft and 5 midget submarines. In an astonishing achievement, the enemy managed to apply in one shattering operation a combination of the principles of surprise, objective, mass, security, and maneuver. In its larger strategic context, the Pearl Harbor attack also exemplifies the principles of the offensive and economy of force. The joint Congressional committee investigating the attack called it the "greatest military and naval disaster in our Nation's history."


These two attacks—on Pearl Harbor and on the Philippines—effectively crippled American striking power in the Pacific. The Philippines and other American possessions in the western Pacific were isolated, their loss a foregone conclusion. The Hawaiian Islands and Alaska lay open to invasion; the Panama Canal and the cities, factories, and shipyards of the west coast were vulnerable to raids from the sea and air. Months would pass before the United States could regain a capacity for even the most limited kind of offensive action against its oriental enemy. As Japanese forces moved swiftly southward against the Philippines, Malaya, and the Netherlands Indies, Japan's Axis partners, Germany and Italy, promptly declared war on the United States, thus ending the uncertainty as to whether the United States would become a full-fledged belligerent in the European war. For the first time in its history, the United States was embarked upon an all-out, two-front war.


Meanwhile Britain was battling to maintain its hold on the eastern Mediterranean region which lay athwart the historic lifeline to possessions and Commonwealth associates in the Far East. Late in 1940 small British forces based in Egypt gained important successes against Italian armies in Libya, and the Greeks in the winter of 1940-41 resoundingly defeated an invading Italian army and chased it back into Albania. But German armies quickly came to the aid of their Italian ally. In April 1941 the famous panzer divisions, supported by overwhelming air power, swept through the Balkans, crushing the Yugoslav and Greek armies, and a British expeditionary force hastily dispatched to aid the latter. The following month German airborne forces descended on the island of Crete and swamped British and Greek defenders in a spectacular, though costly, attack. In Libya a powerful German-Italian army under General Erwin Rommel drove the British back across the Egyptian border, isolating a large garrison in Tobruk and threatening the Nile Delta. Against these disasters Britain could count only the final expulsion of the Italians from the Red Sea area and of the Vichy French from Syria, the suppression of pro-German uprisings in Iraq, and the achievement of a precarious naval ascendancy in the eastern and western portions of the Mediterranean. During the remainder of




1941 the British gradually built up strength in eastern Libya, and late in the year they succeeded in relieving Tobruk and pushing Rommel back to his original starting point at El Agheila.


Since mid-1940 the military fortunes of the anti-Axis powers had declined as the European war expanded. Germany had crushed all its continental European opponents in the west, and then attempted to destroy Britain's air forces as a prelude to an invasion across the English Channel. In the air battles over Britain in August and September 1940 the Royal Air Force won a brilliant victory. But during the following winter and spring the waning threat of invasion had been replaced by the equally deadly and more persistent menace of economic strangulation. German aircraft pulverized Britain's ports and inland cities, while U-boats, surface raiders, and mines decimated shipping. By 1941 the imports on which the United Kingdom depended for existence had dwindled to less than two-thirds of their prewar volume, and the British people faced the prospect of ultimate starvation.


In June 1941, however, the storm center of the war had moved elsewhere. Only slightly delayed by the conquest of the Balkans, Hitler on June 22, 1941, hurled German might against the Soviet Union, the only remaining power on the European continent capable of challenging his dominance. By early December, when the onset of winter and stiffening Soviet resistance finally brought the advance to a halt, the German armies had driven to the suburbs of Moscow, inflicted huge losses on the Red Army, and occupied a vast expanse of European Russia embracing its most densely populated and industrialized regions. This, as it turned out, was the high tide of German success in World War II; Hitler, like Napoleon, was to meet disaster on the wind-swept plains of Russia. But in December 1941 few were willing to predict this outcome. British and United States leaders assembling in Washington at the end of that month to make plans for dealing with the crisis had to reckon with the probability that in the year to come, unless the Western Allies could somehow force Germany to divert substantial forces from the eastern front, the German steamroller would complete the destruction of the Soviet armies. Hitler would then be able, with the resources and enslaved peoples of all Europe at his feet, to throw his full power against the West.


American military leaders had already given thought to this grim prospect, and to the implications it held for America's role in the war. In the Victory Program, drawn up by the Army and Navy at the President's behest during the summer of 1941, the leaders of the two services had set forth in some detail the strategy and the means they considered necessary to win ultimate victory if, as they expected, Soviet Russia succumbed to the Axis onslaught. The strategy




was the one laid down in the RAINBOW 5 war plan—wear Germany down by bombing, blockade, subversion, and limited offensives, while mobilizing the strength needed to invade the European continent and to defeat Germany on its own ground. Japan meanwhile would be contained by air and sea power, local defense forces, China's inexhaustible manpower, and the Soviet Union's Siberian divisions. With Germany out of the running, Japan's defeat or collapse would soon follow. As for the means, the United States would have to provide them in large part, for the British were already weary and their resources limited. The United States would serve not merely, to use the President's catchy phrase, as the "arsenal of democracy," supplying weapons to arm its allies, but also as the main source of the armies without which wars, above all this war, could not be won. Army leaders envisaged the eventual mobilization of 215 divisions, 61 of them armored, and 239 combat air groups, requiring a grand total, with supporting forces, of 8.8 million men. Five million of these would be hurled against the European Axis. It was emphasized that victory over the Axis Powers would require a maximum military effort and full mobilization of America's immense industrial resources.


Yet the Victory Program was merely an expression of professional military views, not a statement of national military policy. That policy, on the eve of Pearl Harbor, was still ostensibly hemisphere defense. The pace of rearmament and mobilization, in the summer and fall of 1941, was actually slowing down. Signs pointed to a policy of making the American contribution to the defeat of the Axis, as columnist Walter Lippmann put it, one "basically of Navy, Air, and manufacturing," something a great deal less than the all-out effort envisaged in the Victory Program. Public and Congressional sentiment, moreover, still clung to the hope that an immediate showdown with the Axis Powers could be avoided and that the country would not be forced into full belligerent participation in the war, as evidenced by a near defeat of the bill to extend Selective Service, continuation of a prohibition against sending selectees outside the Western Hemisphere, and apathetic public response to submarine attacks on American destroyers in September and October.


The Japanese attack on Pearl Harbor and the Philippines changed the picture. A wave of patriotic indignation over Japanese duplicity and brutality swept the country. Isolationism virtually evaporated as a public issue, and all parties closed ranks in support of the war effort. Indeed, in retrospect, despite the immediate tactical success the Japanese achieved at Pearl Harbor, that attack proved to be a great blunder for them, politically and strategically. The President, early in January, dramatized the magnitude of the effort now demanded by proclaiming a new set of production goals—60,000 airplanes in




1942 and 125,000 in 1943; 45,000 tanks in 1942 and 75,000 in 1943; 20,000 antiaircraft guns in 1942 and 35,000 in 1943; half a million machine guns in 1942 and as many more in 1943; and 8 million deadweight tons of merchant shipping in 1942 and 10 million in 1943. Vanished were the two illusions that America could serve only as an arsenal of democracy, contributing weapons without the men to wield them, or, conversely, that the nation could rely solely on its own fighting forces, leaving other anti-Axis nations to shift for themselves. "We must not only provide munitions for our own fighting forces," Roosevelt advised Secretary of War Henry L. Stimson, "but vast quantities to be used against the enemy in every appropriate theater of war." A new Victory Program boosted the Army's ultimate mobilization goal to 10 million men, and the War Department planned to have 71 divisions and 115 combat air groups organized by the end of 1942, with a total of 3.6 million men under arms. As an Army planner had predicted back in the spring of 1941, the United States now seemed destined to become "the final reserve of the democracies both in manpower and munitions."


Late in December 1941 President Roosevelt and Prime Minister Churchill met with their advisers in Washington (the ARCADIA Conference) to establish the bases of coalition strategy and concert immediate measures to meet the military crisis. They faced an agonizing dilemma. Prompt steps had to be taken to stem the spreading tide of Japanese conquest. On the other hand, it seemed likely that the coming year might see the collapse of Soviet resistance and of the British position in the Middle East. In this difficult situation the Allied leaders made a far-reaching decision that shaped the whole course of the war. Reaffirming the principle laid down in Anglo-American staff conversations in Washington ten months earlier, they agreed that the first and main effort must go into defeating Germany, the more formidable enemy. Japan's turn would come later. Defeating Germany would involve a prolonged process of "closing and tightening the ring" about Fortress Europe. Operations in 1942 would have to be defensive and preparatory, though limited offensives might be undertaken if the opportunity offered. Not until 1943 at the earliest could the Allies contemplate a return to the European continent "across the Mediterranean, from Turkey into the Balkans, or by landings in Western Europe."


Another important action taken at the ARCADIA Conference was the establishment of the Combined Chiefs of Staff (CCS). This was a committee consisting of the professional military chiefs of both countries, responsible to the President and Prime Minister for planning and directing the grand strategy of the coalition. Its American members were the Army Chief of Staff, General Marshall; the Chief of Naval Operations, Admiral Harold R. Stark (replaced




early in 1942 by Admiral Ernest J. King); and the Chief (later Commanding General) of the Army Air Forces, Lt. Gen. Henry H. Arnold. In July 1942 a fourth member was added, the President's personal Chief of Staff, Admiral William D. Leahy. Since the CCS normally sat in Washington, the British Chiefs of Staff, making up its British component, attended in person only at important conferences with the heads of state. In the intervals they were represented in Washington by the four senior members of the permanent British Joint Staff Mission, headed until late in 1944 by Field Marshal Sir John Dill, the former Chief of the British Imperial General Staff. Under the CCS a system of primarily military subordinate committees grew up, specifically designated to handle such matters as strategic and logistical planning, transportation, and communications.


By February 1942 the Joint Chiefs of Staff (JCS), consisting of the U.S. members of the CCS, had emerged as the highest authority in the U.S. military hierarchy (though never formally chartered as such), and responsible directly to the President. Like the CCS, the JCS in time developed a machinery of planning and working committees, the most important of which were the Joint Staff Planners, the Joint Strategic Survey Committee, and the Joint Logistics Committee. No executive machinery was created at either the CCS or JCS level. The CCS ordinarily named either the British Chiefs or the U.S. Joint Chiefs to act as its executive agent, and these, in turn, employed the established machinery of the service departments.


In the spring of 1942 Britain and the United States agreed on a worldwide division of strategic responsibility. The U.S. Joint Chiefs of Staff were to be primarily responsible for the war in the Pacific, and the British Chiefs for the Middle East-Indian Ocean region, while the European-Mediterranean-Atlantic area would be a combined responsibility of both staffs. China was designated a separate theater commanded by its chief of state, Chiang Kai-shek, though within the United States' sphere of responsibility. In the Pacific, the Joint Chiefs established two main theaters, the Southwest Pacific Area (SWPA) and the Pacific Ocean Areas (POA), the former under General MacArthur, the latter under Admiral Chester W. Nimitz. POA was further subdivided into North, Central, and South Pacific areas, the first two directly controlled by Nimitz, the third by his deputy, Admiral William F. Halsey, Jr. (See Map 41.) Later in 1942, the U.S. air and service troops operating in China, India, and northern Burma were organized as U.S. Army Forces, China-Burma-India, under Lt. Gen. Joseph W. Stilwell. On various other far-flung lines of communications U.S. Army forces, mostly air and service troops during 1942, were organized under similar theater commands. In June Maj. Gen. Dwight D. Eisenhower




arrived in England to take command of the newly established European Theater of Operations, and after the landings in North Africa late in the year a new U.S. theater was organized in that region.


The British and the Americans had decided at the ARCADIA Conference that Allied forces in each overseas theater would operate, as far as possible, under a single commander, and this principle was subsequently applied in most theaters. Within theaters subordinate unified commands were created, in some cases for Allied ground, naval, or air forces, and most frequently for task forces formed to carry out a specific operation or campaign. The authority of Allied theater commanders over national forces was always restricted with respect to areas and missions and, as a last resort, senior national commanders in each theater could appeal to their own governments against specific orders or policies of the theater commander. In practice, this right of appeal was rarely invoked.


In essence, unified command at the Allied level gave the commander control of certain specific forces for operational purposes, rather than jurisdiction over a given geographical area. Administration of national forces and the allocation of resources were usually handled through separate national channels. In certain cases, inter-Allied boards or committees, responsible to the Allied theater commander, controlled the common use of critical resources (such as petroleum products) or facilities (such as railways and shipping) within a theater. Administration of U.S. forces overseas also generally followed separate Army and Navy channels, except in the Pacific where, from 1943 on, supply, transportation, and certain other services were jointly administered to a limited degree.


Even before Pearl Harbor, Army leaders had realized that the peacetime organization of the War Department General Staff, dating back to 1921, was an inadequate instrument for directing a major war effort. Originally a small coordinating and planning body, the General Staff, and especially its War Plans and Supply Divisions, rapidly expanded during the emergency period into a large operating organization, increasingly immersed in the details of supervision to the detriment of its planning and policy-making functions. The Chief of Staff, to whom some sixty-one officers and agencies had direct access, carried an especially heavy burden.


Three additional features of the organization demanded remedy. One was the continued subordination of the Army Air Forces to General Staff supervision, which conflicted with the Air Forces' drive for autonomy. Another was the anomalous position of General Headquarters (GHQ), whose role as command post for the field forces and responsibilities in the fields of training




and logistics clashed with the authority of the General Staff at many points. Finally, the division of supply responsibilities between the Supply Division (G-4) and the Office of the Under Secretary of War—with requirements and distribution assigned to the former and procurement to the latter—was breaking down under the pressure of mobilization.


Spurred by the Pearl Harbor disaster, which seemed to accentuate the need for better staff co-ordination in Washington, General Marshall on March 9, 1942, put into effect a sweeping reorganization of the War Department. Under the new plan, which underwent little change during the war years, the General Staff, except for the War Plans and Intelligence Divisions, was drastically whittled down and limited in function to broad planning and policy guidance. An expanded War Plans Division, soon renamed Operations Division (OPD), became (general Marshall's command post and, in effect, a superior general staff for the direction of overseas operations. The Army Air Forces, though in some respects on a lower level of administrative authority than before, had virtually complete control of the development of its special weapon—the airplane. Administering its own personnel and training, it organized and supported the combat air forces to be employed in theaters of operations and came also to exercise considerable influence over both strategic and operational planning.


In the reorganization of March 9 two new commands were created, the Army Ground Forces (AGE) and the Services of Supply, later renamed the Army Service Forces (ASF). The former, headed by Lt. Gen. Lesley J. McNair, took over the training mission of GHQ, now abolished, and absorbed the ground combat arms. To the ASF, commanded by Lt. Gen. Brehon B. Somervell; were subordinated the supply (renamed technical) and administrative services, the nine corps areas, and most of the Army posts and installations throughout the United States, including the ports of embarkation through which troops and supplies flowed to the forces overseas. In supply matters, Somervell now reported to two masters, the Chief of Staff for requirements and distribution and the Under Secretary of War, Mr. Robert P. Patterson, for procurement. His subordination to the latter was, in reality, only nominal since most of Patterson's organization was transferred bodily to Somervell's headquarters. Except for equipment peculiar to the Army Air Forces, the ASF thus became the Army's central agency for supply in the United States. It drew up the Army's "shopping list" of requirements, the Army Supply Program; through the seven technical services (Quartermaster, Ordnance, Signal, Chemical, Engineer, Medical, and Transportation) it procured most of the Army's supplies and equipment; it distributed these materials to the Army at home and abroad, as well as to




Allies under lend-lease; it operated the Army's fleet of transports; and it trained specialists and service units to perform various specialized jobs. General Somervell himself became General Marshall's principal logistical adviser.


All this looked to the future. In the first few weeks after Pearl Harbor, while the Navy was salvaging what it could from the wreckage at Pearl Harbor and striving to combat German submarines in the western Atlantic, the War Department made desperate efforts to bolster the defenses of Hawaii, the Philippines, the Panama Canal, Alaska, and the U.S. west coast. By the end of December, the danger of an attack on the Hawaii-Alaska-Panama triangle seemed to have waned, and the emphasis shifted to measures to stave off further disasters in the Far East. The British and Americans decided at ARCADIA that the Allies would attempt to hold the Japanese north and east of the line of the Malay Peninsula and the Netherlands Indies and to re-establish communications with the Philippines to the north. To co-ordinate operations in this vast theater, the Allied leaders created the ABDA (American-British-Dutch-Australian) Command, including the Netherlands Indies, Malaya, Burma, and the Philippines. British Lt. Gen. Sir Archibald P. Wavell was placed in over-all command. Through India from the west and Australia from the east, the Allies hoped in a short time to build up a shield of air power stout enough to blunt the Japanese threat.


For a time it seemed as though nothing could stop the Japanese juggernaut. In less than three weeks after Pearl Harbor, the isolated American outposts of Wake and Guam fell to the invaders, the British garrison of Hong Kong was overwhelmed, and powerful land, sea, and air forces were converging on Malaya and the Netherlands Indies. Picked, jungle-trained troops drove down the Malay Peninsula toward the great fortress of Singapore, infiltrating and outflanking successive British positions. Two of the most formidable warships in the British Navy, the battleship Prince of Wales and the battle cruiser Repulse, were sunk by Japanese torpedo planes off the east coast of Malaya, a loss that destroyed the Allies' last hope of effectively opposing Japan's naval power in the Far East. Attacked from the land side, Singapore and its British force of over 80,000 troops surrendered on February 15, 1942. Meanwhile the Japanese had invaded the Netherlands Indies from the north, west, and east. In a series of actions during January and February, the weak Dutch and Australian naval forces, joined by the U.S. Asiatic Fleet withdrawing from the Philippines, were destroyed piecemeal, only four American destroyers escaping south to Australia. On March 9 the last Allied ground and air forces in the Netherlands Indies, almost 100,000 men (mostly Indonesian troops) surrendered to the invaders. In Burma, the day before, the British had been




forced under heavy bombing to evacuate Rangoon and retreat northward. Before the end of April the Japanese had completed the occupation of Burma, driving the British westward into India and the bulk of U.S. Lt. Gen. Joseph W. Stilwell's Chinese forces back into China; General Stilwell and the remnants of other Chinese units retreated to India. In the process the Japanese had won possession of a huge section of the Burma Road, the only viable route between China and India. Henceforth and until late in the war communication between China and its allies was to be limited to an air ferry from India over the "hump" of the Himalayan Mountains. During the late spring strong Japanese naval forces reached the coastal cities of India and even attacked Britain's naval base on Ceylon.


By May 1942 the Japanese had thus gained control of Burma, Malaya, Thailand, French Indochina, and the Malay Archipelago, while farther to the east they had won strong lodgments on the islands of New Guinea and New Britain and in the Solomons, flanking the approaches to Australia and New Zealand from the United States. This immense empire had been won at remarkably little cost through an effective combination of superior air and sea power and only a handful of well-trained ground divisions. The Japanese had seized and held the initiative while keeping their opponents off balance. They had concentrated their strength for the capture of key objectives such as airfields and road junctions and for the destruction of major enemy forces while diverting only minimum forces on secondary missions, thus giving an impression of overwhelming numerical strength. They had frequently gained the advantage of surprise and had baffled their enemies by their speed and skill in maneuver. The whole whirlwind campaign, in short, had provided Japan's enemies with a capsule course of instruction in the principles of war.


Fall of the Philippines


Only in the Philippines, almost on Japan's southern doorstep, was the timetable of conquest delayed. When the Japanese struck, the defending forces in talc islands numbered more than 130,000, including the Philippine Army which, though mobilized to a strength of ten divisions, was ill trained and ill equipped. Of the U.S. Army contingent of 31,000, more than a third consisted of the Philippine Scouts, most of whom were part of the Regular Army Philippine Division, the core of the mobile defense forces. The Far East Air Force, before the Japanese attack, had a total of 277 aircraft of all types, mostly obsolescent but including 35 new heavy bombers. Admiral Thomas C. Hart's Asiatic Fleet, based on the Philippines, consisted of 3 cruisers, 13 old destroyers,




(6 gunboats, 6 motor torpedo boats, 32 patrol bombers, and 29 submarines. A regiment of marines, withdrawn from Shanghai, also joined the defending forces late in November 1941. Before the end of December, however, American air and naval power in the Philippines had virtually ceased to exist. The handful of bombers surviving the early attacks had been evacuated to Australia, and the bulk of the Asiatic Fleet, its base facilities in ruins, had withdrawn southward to help in the defense of the Netherlands Indies.


The main Japanese invasion of the Philippines, following preliminary landings, began on December 22, 1941. While numerically inferior to the defenders, the invading force of two divisions with supporting units was well trained and equipped and enjoyed complete mastery of the air and on the sea. The attack centered on Luzon, the northernmost and largest island of the archipelago, where all but a small fraction of the defending forces were concentrated. The main landings were made on the beaches of Lingayen Gulf, in tile northwest, and Lamon Bay in the southeast. General MacArthur's plan was to meet and destroy the invaders on the beaches, but his troops were unable to prevent the enemy from gaining secure lodgments. On December 23 MacArthur ordered a general withdrawal into the mountainous Bataan Peninsula, across Manila Bay from the capital city. Manila itself was occupied by the Japanese without resistance. The retreat into Bataan was a complex operation, involving converging movements over difficult terrain into a cramped assembly area from which only two roads led into the peninsula itself. Under constant enemy attack, the maneuver was executed with consummate skill and at considerable cost to the attackers. Yet American and Filipino losses were heavy, and the unavoidable abandonment of large stocks of supplies foredoomed the defenders of Bataan to ultimate defeat in the siege that followed. An ominous portent was the cutting of food rations by half on the last day of the retreat.


By January 7, 1942, General MacArthur's forces held well-prepared positions across the upper part of the Bataan Peninsula. Their presence there, and on Corregidor and its satellite island fortresses guarding the entrance to Manila Bay, denied the enemy the use of the bay throughout the siege. In the first major enemy offensive, launched early in January, the "battling bastards of Bataan" at first gave ground but thereafter handled the Japanese so roughly that attacks ceased altogether from mid-February until April, while the enemy reorganized and heavily reinforced. The defenders were, however, too weak to seize the initiative themselves.


General MacArthur, meanwhile, was ordered by tile President to leave his post and go to Australia in order to take command of Allied operations against the Japanese in the Southwest Pacific. In mid-March he anal a small party made




their way through the Japanese lines by motor torpedo boat to Mindanao, and from there were flown to Australia. Command of the forces in the Philippines devolved upon Lt. Gen. Jonathan M. Wainwright.


By April the troops on Bataan were subsisting on about fifteen ounces of food daily, less than a quarter of the peacetime ration. Their diet, consisting mostly of rice supplemented by carabao, mule, monkey, or lizard meat, was gravely deficient in vitamins and provided less than Togo calories a day, barely enough to sustain life. Weakened by hunger and poor diet, thousands succumbed to malaria, dengue, scurvy, beriberi, and amoebic dysentery, made impossible to control by the shortage of medical supplies, especially quinine. Desperate efforts were made to send food, medicine, ammunition, and other supplies through the Japanese blockade to the beleaguered forces. But during the early weeks, before the enemy cordon had tightened, it proved impossible, despite promises of lavish pay and bonuses, to muster the necessary ships and crews. Even so, sizable stocks were accumulated in the southern islands, but only about 1,000 tons of rations ever reached Manila Bay. Shipments in converted destroyers from the United States were too late and too few, and only insignificant quantities could be brought in by submarine and aircraft.




At the beginning of April the Japanese, behind a pulverizing artillery barrage, attacked again. The American lines crumpled, and in a few days the defending forces virtually disintegrated. On April 9 Maj. Gen. Edward P. King, Jr., commanding the forces on Bataan, surrendered. For almost another month the garrison on Corregidor and the other islands, swelled by refugees from Bataan, held out under air bombardment and almost continuous plunging fire from heavy artillery massed on adjacent shores and heights—one of the most intense artillery bombardments, for so small a target, of the entire war. On the night of May 5, after a final terrific today barrage, Japanese assault troops won a foothold on Corregidor, and the following night, when it became apparent that further resistance was useless, General Wainwright surrendered unconditionally. Under his orders, which the Japanese forced him to broadcast, other American commanders in the Philippines capitulated one by one. By early June, except for scattered guerrilla detachments in the hills, all organized resistance in the islands had ceased.


Deploying American Military Strength


After more than a year and a half of rearming, the United States in December 1941 was still in no position to carry the war to its enemies. On December 7 the Army numbered some 1,644,000 men (including about 120,000 officers), organized into 4 armies, 37 divisions (30 infantry, 5 armored, 2 cavalry), and over 40 combat air groups. Three of the divisions were overseas (2 in Hawaii, 1 in the Philippines), with other garrison forces totaling less than 200,000. By spreading equipment and ammunition thin, the War Department might have put a substantial force into the field to repel an attack on the continental United States; 17 of the divisions at home were rated as technically ready for combat. But these divisions lacked the supporting units and the training necessary to weld them into corps and armies. More serious still, they were inadequately equipped with many weapons that recent operations in Europe had shown to be indispensable—for example, tank and antitank guns, antiaircraft artillery, radios, and radar—and some of these shortages were aggravated by lack of auxiliary equipment like fire control mechanisms.


Above all, ammunition of all kinds was so scarce that the War Department was unwilling to commit more than one division and a single antiaircraft regiment for service in any theater where combat operations seemed imminent. Only one division-size task force, in fact, was sent to the far Pacific before April 1942. Against air attacks, too, the country's defenses were meager. Along the Pacific coast the Army had only 45 modern fighter planes ready to fly, and only twelve




3-inch antiaircraft guns to defend the whole Los Angeles area. On the east coast there were only 54 Army fighter planes ready for action. While the coastal air forces, primarily training commands, could be reinforced by airlift the interior of the country, the total number of modern fighter aircraft available was less than 1,000. Fortunately, there was no real threat of an invasion in force, and the rapidly expanding output of munitions from American factories promised to remedy one of these weaknesses within a few months. Furthermore, temporary diversions of lend-lease equipment, especially aircraft, helped to holster the overall defense posture within the first few weeks after Pearl Harbor. The Army hoped by April to have as many as thirteen divisions equipped and supplied with ammunition for combat.


To deploy these forces overseas was another matter. Although the U.S. merchant marine ranked second only to Great Britain's and the country possessed an immense shipbuilding capacity, the process of chartering, assembling, and preparing shipping for the movement of troops and military cargo took time. Time was also needed to schedule and organize convoys, and, owing to the desperate shortage of escort vessels, troop movements had to be widely spaced. Convoying and evasive routing, in themselves, greatly reduced the effective capacity of shipping. Moreover, vast distances separated U.S. ports from the areas threatened by Japan, and to these areas went the bulk of the forces deployed overseas during the months immediately following Pearl Harbor. Through March 1942, as a result, the outflow of troops to overseas bases averaged only about 50,000 per month, as compared with upwards of 250,000 during 1944, when shipping was fully mobilized and plentiful and the sea lanes were secure.


There seemed a real danger early in 1942, however, that German U-boats might succeed in reducing transatlantic deployment to a trickle—not so much by attacking troop transports, most of which could outrun their attackers, as by sinking the slow cargo ships on which the forces overseas depended for support. Soon after Germany's declaration of war, the U-boats struck at the virtually unprotected shipping lanes in the western Atlantic, and subsequently extended their attacks to the Gulf of Mexico and Caribbean areas and the mouth of the St. Lawrence. During the spring of 1942 tankers and freighters were torpedoed in plain view of vacationers on east coast beaches, and coastal cities dimmed or extinguished their lights in order that ships might not provide silhouetted targets for the U-boats. The Navy lacked the means to cope with the peril. In late December 1941 it had only twenty assorted surface vessels and about a hundred aircraft to protect the whole North Atlantic coastal frontier. During; the winter and spring these were supplemented by another hundred




Army planes of longer range, several armed British trawlers, and as many improvised craft as could be pressed into service.


But the toll of ship sinkings increased. In March 788,000 deadweight tons of Allied and neutral dry cargo shipping were lost, in June 936,000 tons. Tanker losses reached an all-time peak of 375,000 tons in March, leading to complete suspension of coastal tanker movements and to gasoline rationing in the seaboard states. During the first six months of 1942 losses of Allied shipping were almost as heavy as during the whole of I94I and exceeded new construction by almost 2.8 million deadweight tons. Although the United States was able by May to balance its own current losses by building new ships, Britain and other Allied countries continued until the following August to lose more than they could build, and another year passed before new construction offset cumulative losses.


Slowly and with many setbacks a system of countermeasures was developed. Convoying of coastal shipping, with ships sailing only by day, began in the spring of 1942. North-South traffic between U.S. and Caribbean and South American ports was also convoyed, on schedules interlocked with those of the transatlantic convoys. The latter, during 1942, were protected in the western half of the Atlantic by the U.S. and Canadian Navies, in the eastern half by the British. Troops were transported across the Atlantic either without escort in large, speedy liners like the Queen Elizabeth and the Queen Mary—which between them carried almost a quarter of all U.S. troops sent to Europe—or in heavily escorted convoys. Throughout the war, not a single loaded troop transport was sunk on the United Kingdom run. The slow merchant ships were convoyed in large groups according to speed.


But with responsibility for U.S. antisubmarine operations divided between the Navy and Army Air Forces, effective co-operation was hampered by sharp disagreement over organization and methods, and available resources throughout 1942 were inadequate. The U-boats, meanwhile, were operating with deadly effect and in growing numbers. Late in the year they began to hunt in packs, resupplied at sea by large cargo submarines ("milch cows"). The Allied convoys to Murmansk and other northern Soviet ports suffered especially heavy losses on their long passage around the top of the Scandinavian peninsula. In November shipping losses from all causes soared above I.I million deadweight tons— the peak, as it turned out, for the entire war, but few at the time dared so to predict.


In the Pacific, fortunately, the principal barriers to deployment of U.S. forces were distance and lack of prepared bases, not enemy submarines. Japan's Beet of undersea craft made little effort to prey on the Allied sea lanes and




probably over the vast reaches of the Pacific, could not have inflicted serious damage in any case. The chief goal of American deployment to the Pacific during most of 1942, following the initial reinforcement of Hawaii and the Panama Canal, was to build up a base in Australia and secure the chain of islands leading to it. Australia was a vast, thinly populated, and except in its southeastern portion, largely undeveloped island continent, 7,000 miles and almost a month's sail from the U.S. west coast. It had provided a haven for some 4,000 American troops who, on December 7, had been at sea, bound for the Philippines, and in January a task force of division size (POPPY Force) was hastily assembled and dispatched to New Caledonia to guard its eastern approaches. During the first few weeks the main effort of the small American forces went into sending relief supplies to the Philippines and aircraft and troops to Java to stem the Japanese invasion. Beginning in March, as the futility of these efforts became evident, and coincident with the arrival of General MacArthur to assume command of all Allied forces in the Southwest Pacific, the construction of base facilities and the build-up of balanced air and ground forces got under way in earnest.


This build-up had as its first object the defense of Australia itself, for at the end of January the Japanese had occupied Rabaul on New Britain Island, thus closing an immediate threat to Port Moresby, the weakly held Australian base in southeastern New Guinea. In February President Roosevelt pledged American help in countering this threat, and in March and April two infantry divisions (the 41st and 32d) left the United States for the Southwest Pacific. At the same time, construction of air and refueling bases was being rushed to completion in the South Pacific islands that formed steppingstones along the ocean routes to Australia and New Zealand. After the western anchor of this chain, New Caledonia, was secured by the POPPY Force, Army and Marine garrisons and reinforcements were sent to various other islands along the line, culminating with the arrival of the 37th Division in the Fiji Islands in June.


These moves came none too soon for, during the spring, the Japanese, after occupying Rabaul, pushed into the southern Solomons, within easy striking distance of the American bases on Espíritu Santo and New Caledonia. They also occupied the northeastern coast of New Guinea, just across the narrow Papuan peninsula from Port Moresby, which the Americans and Australians were developing into a major advanced base in preparation for an eventual offensive northward. The stage was thus set for a major test of strength in the Pacific—American forces spread thinly along an immense arc from Hawaii to Australia with outposts far to the north in Alaska; the Japanese securely in possession of the vast areas north and west of the arc and, with the advantage




of interior lines, prepared to strike in force at any point. The first test came in May, when the Japanese made an attempt from the sea to take Port Moresby. This was successfully countered in the great carrier battle of the Coral Sea. Thereupon the Japanese struck eastward, hoping to destroy the U.S. Pacific Fleet and to seize Midway—a bid for naval supremacy in the Pacific. A diversionary attack on Dutch Harbor, the most forward U.S. base in Alaska, caused considerable damage, and the Japanese were able to occupy the islands of Kiska and Attu in the foggy Aleutian chain. But the main Japanese forces, far to the south, were crushingly defeated, with especially heavy losses in carriers and aircraft. The Battle of Midway in June Ig42 was one of the truly decisive engagements of the war. By seriously weakening Japan's mobile striking forces, Midway left the Japanese virtually helpless to prevent the consolidation of American positions and the eventual development of overwhelming military supremacy throughout the Pacific. Only two months later, in fact, American forces took the first step on the long "road back" by landing on Guadalcanal in the southern Solomons.


Although the RAINBOW 5 plan was put into effect immediately after Pearl Harbor, the desperate situation in the Pacific and Far East and the shortage of shipping and escorts ruled out most of the scheduled Atlantic, Caribbean, and South American deployments. In January reinforcements were sent to Iceland and a token force to Northern Ireland, and by June two full divisions (the 34th Infantry and the 1st Armored) had reached Ireland, while the remainder of the 5th Infantry had arrived in Iceland, completing the relief of the U.S. Marine brigade and most of the British garrison. No more divisions sailed eastward until August. Meanwhile, garrisons in the Atlantic and Caribbean were being built up to war strength. But plans to occupy the Azores, Canaries, and Cape Verdes, and to capture Dakar on the west African coast went by the board, primarily for lack of shipping. Also abandoned after lengthy discussion was a project (GYMNAST) proposed by Prime Minister Churchill at the ARCADIA Conference for an Anglo-American occupation of French North Africa.


Thus, despite the reaffirmation of the "Germany first" strategy at ARCADIA, the great bulk of American forces sent overseas during the first half of 1942 went to the theaters of war against Japan. Of the eight Army divisions that left the country before August, five went to the Pacific. Including two more already in Hawaii, and a Marine division at sea, bound for New Zealand (eventually for the landings on Guadalcanal in August), eight divisions were deployed against Japan in July 1942. Of the approximately 520,000 Army troops in overseas bases, 60 percent were in the Pacific (including Alaska) and the newly-established China-Burma-India theater; the remainder were almost all




in Caribbean and western Atlantic garrisons. Of 2,200 Army aircraft overseas, about 1,300 were in the Pacific (including Alaska) and Far East, goo in the western Atlantic and Latin America. Not until August did the U.S. Army Air Forces in the British Isles attain sufficient strength to fly a single independent bombing mission over northern France.


Planning for a Cross-Channel Invasion


T he Army's leaders and planners, schooled in a tradition that emphasized the principles of mass and offensive, had been fretting over the scale of deployment to the Pacific since early in the year. Late in January Brig. Gen. Dwight D. Eisenhower, then a War Department staff officer whom General Marshall had assigned to handle the crisis in the Pacific, noted, "We've got to go to Europe and fight—and we've got to quit wasting resources all over the world." In the joint committees Army planners urged that as soon as the situation could be stabilized in the Southwest Pacific, U.S. forces should begin to concentrate in the British Isles for an offensive against Germany. Secretary Stimson and others were pressing the same views on the President. In the middle of March the Joint Chiefs of Staff approved this course of action, and in April, at the President's order, General Marshall and Harry Hopkins, the President's personal representative, went to London to seek British approval.


Logistical considerations heavily favored both the general strategy of concentration against Germany and the specific plan of invading northwestern Europe from a base in the British Isles. Because the target area was close to the main sources of British and American power, two to three times as many forces could be hurled against northwestern Europe, with a given amount of shipping, as could be supported in operations against Japan. Britain itself was a highly industrialized country, fully mobilized after two and a half years of war, and well shielded by air and naval power—a ready-made base for a land invasion and air attacks on Germany's vitals. While invasion forces were assembling, moreover, they would serve to garrison the British Isles. Finally, an attack across the English Channel would use the only short water crossing to the Continent from a base already available and would thrust directly at the heart of Fortress Europe by the main historic invasion routes.


Even so, the plan was a desperate gamble. If northwestern Europe offered the Allies a position of strength, the Germans, too, would be strong there, close to their own heartland, served by the superb rail and road net of western and central Europe shielded by submarines based along the entire length of Europe's Atlantic front. The limited range of fighter aircraft based in southern England




narrowly restricted the choice of landing areas. Much hinged on the USSR, where for the present the bulk of Germany's land forces were pinned down. If the Soviet Union collapsed, an invasion from the west would be a suicidal venture. The invasion must therefore be launched before the Soviet armies were crushed and, moreover, in sufficient strength to draw substantial German forces away from the Eastern Front in order to avert that very catastrophe.


On the face of it, these two requirements seemed to cancel each other. For Allied planners had little hope that the Russians could stand up under another summer's onslaught, and it was obvious, in view of the scarcity of shipping, that any attack the Western Allies could mount by the coming summer or early fall would be hardly more than a pinprick. The best solution General Marshall's planners could offer to this dilemma was to set the invasion for the spring of 1943 (ROUNDUP), in the hope that until then, through air bombardment of Germany and a continued flow of materiel to the Soviet Union, the Allies could help the Soviet armies to stave off defeat. If these measures should fail, and Soviet resistance seemed about to collapse, then, with whatever forces were on hand, the Allies would have to invade the Continent in 1942 (SLEDGEHAMMER)— and no later than September, before bad weather closed down over the Channel. The same course would be followed in the unlikely event that Germany itself showed signs of serious weakness in 1942.


In London, Mr. Hopkins and General Marshall found the British delighted that the United States was ready to commit itself to a major offensive against Germany in 1943. The British readily agreed that preparations should begin immediately for an invasion the following spring, and they undertook to provide more than half the shipping needed to move about a million American troops and immense quantities of materiel to the United Kingdom. They warned, however, that their first concern at present was to maintain their position in the Middle East, where, late in January, Rommel's revitalized Africa Korps had inflicted a serious reverse on the Eighth Army. Both sides were now feverishly building up for a new offensive. The British also expressed deep misgivings over the proposed emergency cross-Channel operation in the fall. Nevertheless, the British approved the American plan, essentially the War Department's plan, "in principle"—a phrase that was to give much trouble in the coalition war. The immediate relief felt by General Marshall's staff in Washington was reflected by General Eisenhower, then Chief, Operations Division, War Department General Staff, who noted: ". . . at long last, and after months of struggle . . . we are all definitely committed to one concept of fighting If we can agree on major purposes and objectives, our efforts will begin to fall in line and we won't just be thrashing around in the dark."




But on the American side, too, there were strong reservations. Admiral King did not contest in principle the "Germany first" strategy. But he was determined not to allow preparations for the cross-Channel invasion to jeopardize "vital needs" in the Pacific, by which, as he candidly stated early in May, he meant the ability of U.S. forces "to hold what we have against any attack that the Japanese are capable of launching." Only the President's peremptory order on May 6 that the invasion build-up in Britain must not be slowed down (it had, indeed, scarcely begun) prevented a large-scale diversion of forces and shipping to the Pacific to counter the Japanese offensive that culminated in the great naval battles of the Coral Sea and Midway. The President himself made it clear, on the other hand, that aid to the Soviet Union would have to continue on a mounting scale, whatever the cost to Bolero (the American build-up in the United Kingdom) in materiel and shipping. And even Army leaders were unwilling to assign shipping for the movement until the scheduled build-up of garrisons in the Western Hemisphere and various other overseas stations had been completed, which, it was estimated, would not be until August at the earliest. Until then British shipping would have to carry the main burden.


Not until June 1942, therefore, did the first shipload of American troops under the new plan set sail for England in the great British luxury liner, Queen Elizabeth. Almost simultaneously a new crisis erupted in the Middle East. At the end of May, after a four-month lull, Rommel seized the initiative and swept around the southern flank of the British Eighth Army, which held strong positions in eastern Libya from El Gazala on the coast south to Bir Hacheim. After two weeks of hard fighting, in which the British seemed to be holding their own, Rommel succeeded in taking Bir Hacheim, the southern anchor of the British line. During the next few days British armor, committed piecemeal in an effort to cover a withdrawal to the northeast, was virtually wiped out by skillfully concealed German 88-mm. guns. The Eighth Army once again retreated across the Egyptian frontier, and on June HI Tobruk, which the British had expected, as in I94I, to hold out behind Axis lines, was captured with its garrison and large stores of trucks, gasoline, and other supplies.


News of this disaster reached Prime Minister Churchill in Washington, where he had gone early in the month to tell the President that the British were unwilling to go through with an emergency cross-Channel landing late in 1942. General Marshall immediately offered to send an armored division to help the hard-pressed British in Egypt, but it was decided, for the present, to limit American aid to emergency shipments of tanks, artillery, and the ground components of three combat air groups. This move required the diversion for many weeks of a substantial amount of U.K. shipping from the North Atlantic on




the long voyage around the Cape of Good Hope. But the heaviest impact on the invasion build-up in the United Kingdom resulted from the diversion of British shipping to the Middle East and the retention there of shipping the British had earmarked for the build-up. For the time being, British participation in the BOLERO program virtually ceased.


By the end of August, with only seven months to go before the invasion was to be launched, only about 170,000 American troops were in or on their way to the British Isles, and the shipment of equipment and supplies, particularly for the development of cantonments, airfields, and base facilities, was hopelessly behind schedule. There seemed little likelihood that enough shipping would be available to complete the movement across the Atlantic of a million troops, with the ten to fifteen million tons of cargo that must accompany them, by April 1943 as scheduled. And even if the shipping could have been found, Britain's ports and inland transportation system would have been swamped before the influx reached its peak. Thus, by the late summer of 1942, a spring 1943 ROUNDUP appeared to be a logistical impossibility.


Torch Replaces Sledgehammer-Roundup


By this time, in fact, American military leaders had become discouraged about a cross-Channel invasion in spring of 1943, though not primarily because of the lag in the build-up program. In June the British had decided that SLEDGEHAMMER, for which they had never had any enthusiasm, could not be undertaken except in a situation which offered good prospects of sass—that is, if the Germans should seem about to collapse. At the moment, with the German summer offensive just starting to roll toward the Caucasus and the lower Don, such a situation did not appear to be an imminent possibility. The British decision was influenced in part by the alarming lag in deliveries of American landing craft, of which less than two-thirds of the promised quota for the operation was expected to materialize. The British also argued that the confusion and losses attendant upon executing SLEDGEHAMMER—and the cost of supporting the beachhead once it was established—were likely to disrupt preparations for the main invasion the following spring. Since SLEDGEHAMMER, if carried out, would have to be, in the main, a British undertaking, the British veto was decisive. The operation was canceled.


As a substitute, the British proposed a less risky venture—landings in French North Africa—which they were confident could be accomplished in stride, without harm to ROUNDUP. To Stimson, Marshall, King, and Arnold this proposal was anathema. Failure would be a costly, perhaps fatal rebuff to Allied prestige.




Success might be even more dangerous, the Americans feared, for it might lead the Allies step by step into a protracted series of operations around the southern periphery of Europe, operations that could not be decisive and would only postpone the final test of strength with Germany. At the very least, an invasion of North Africa would, the Americans were convinced, rule out a spring 1943 invasion of the Continent. The Army planners preferred the safer alternative of simply reinforcing the British in Egypt.


The British proposal was, nevertheless, politically shrewd, for it was no secret that President Roosevelt had long ago expressed a predilection for this very undertaking. He was determined, besides, that American ground forces go into action somewhere in the European area before the end of 1942. Already half Persuaded, he hardly needed Churchill's enthusiastic rhetoric to win him over to the new project. When General Marshall and his colleagues in the Joints Chiefs of Staff suggested, as an alternative, that the United States should immediately go on the defensive in Europe and turn all-out against Japan, Roosevelt brusquely rejected the idea.


In mid-July, Hopkins, Marshall, and King went to London under orders from the President to reach agreement with the British on some operation in 1942. After a vain effort to persuade the British to reconsider an invasion of the Continent in 1942, the Americans reluctantly agreed on July 24 to the North Africa operation, now christened TORCH, to be launched before the end of October. The President, overruling Marshall's suggestion that final decision be postponed until mid-September in order to permit a reappraisal of the Soviet situation, cabled Hopkins that he was "delighted" and that the orders were now "fun speed ahead." Into the final agreement, however, Marshall and King wrote their own conviction that the decision on TORCH "in all probability" ruled out invasion of the Continent in 1943 and meant, further, that the Allies had accepted "a defensive, encircling line of action" in the European-Mediterranean war.


End of the Defensive Stage


With the decision for TORCH, the first stage in the search for a strategic plan against Germany came to an end. In retrospect, 1941-42 had been a period of defensive strategy, and a strategy of scarcity. The British and American approaches to war had had their first conflict, and the British had won the first round. That British notions of strategy had tended to prevail was not surprising. British forces had been mobilized earlier and were in the theaters in far greater numbers than American forces. The United States was still mobilizing its manpower and resources. It had taken the better part of the year after Pearl




Harbor for U.S. forces to have an appreciable effect in the theaters. Strategic planning in 1942 had been largely opportunistic, hand to mouth, and limited by critical shortages in shipping and munitions. Troops had been parceled out piecemeal to meet immediate threats and crises. Despite the "Germany first" decision, the total U.S. Army forces deployed in the war against Japan by the end of the year actually exceeded the total U.S. Army forces deployed in the war against Germany. The one scheme to put Allied planning on an orderly, long-range basis and to achieve the concepts of mass and concentration in which General Marshall and his staff had put their faith had failed. By the close of the critical first year after Pearl Harbor, an effective formula for halting the dissipation of forces and materiel in what it regarded as secondary ventures still eluded the Army high command.
