10 See Pearl Harbor Attack, Part 34, PP. 47-48 for declaration that the Intelligence Estimate of 29 November 1941 "does not include in the lines of action open to Japan an attack on Pearl Harbor." General Miles' view (p. 57) was that an air attack on Pearl Harbor had been studied for 20 years and was omitted from this estimate "presumably because it was so obvious." General Gerow's view was that the Japanese inquiries about die Panama Canal (much less stressed in the inquiries) forced the American military to be quite as much on guard there, even though no attack on the Canal eventuated, for bombing of the Panama locks could have affected the fleet seriously. In brief, General Gerow explained, had WPD not been concerned with both Panama and Hawaii, it would have been remiss. "It was probable that they might attack any one of our four major areas bordering on the Pacific." Pearl Harbor Attack, Part 4, P. 1653.

11 Asked at the Army inquiry of 1944 what were War Department conclusions in the 2941 autumn, General Marshall said: " We anticipated, beyond a doubt, a Japanese movement in Indo-China and the Gulf of Siam and against the Malay peninsula. We did not, so far as I can recall, anticipate an attack on Hawaii; the reason being that we thought with the addition of more modern planes that the defenses there would make it extremely hazardous for the Japanese to attempt such an attack." Pearl Harbor Attack, Part 27, Proceedings of the Army Pearl Harbor Board, p. 14. See also Pearl Harbor Attack, Part 39, Report of the Army Pearl Harbor Board, P. 439, recording the ejaculation of Secretary Knox on 7 December when informed of the raid at Pearl Harbor, ' :My God, this can't be true. This must mean the Philippines." Sec also in Report, p. 76, Vice Adm. W. S. Pye's recollection of Secretary Knox' visit to Pearl Harbor shortly after the attack, specifically the Secretary's opening; remark that "no one- in Washington expected an attack---even Kelly Turner," Admiral Turner then being; Navy WPD chief and "the most aggressive-minded of all." On the other hand, General Miles, the ACofS (:-2 in 1941, informed the joint Committee in 1945: "We knew a surprise attack was possible . . . . Hut we knew also that then: was no possible way that we could see of warding; off or detecting, a surprise attack except by reconnaissance from Hawaii, whether that reconnaissance was air or surface or sub-surface or radar." Pearl Harbor Attack, part 2, p. 823. As to omitting Hawaii from the list of possible targets named in the estimates, this chief 0f Intelligence declared that such a mention was not considered necessary because "it was a fortress built for one sole purpose, defense in a Japanese war . . . ." Ibid., p. 838.

12 Report of the joint Committee on the Investigation of the Pearl Harbor Attack, Congress of the United States, pursuant to S Con Res 27, 79th Cong, with additional and minority views, (apart from the thirty-nine volumes of Hearings), is printed as Document 244, 79th Gong„ 2d sess (Washington, 1946). It covers 540 printed pages. The testimony of the hearings before this committee, plus exhibits which include the reports of 7 earlier hearings, is found in 39 volumes under the general title Pearl Harbor Attack. Those earlier inquiries, with their appropriate numbers as Committee Exhibits are (1) Roberts Commission-243; Admiral Thomas C. Hart-244; Army's Pearl Harbor Board-145; Navy Court of Inquiry-246; Col Carter W. Clarkc-247; Maj Henry C. Clausen-248; Admiral H. Kent Hcwitt-249. Sec Morison, The Rising Sun In The Pacific, specifically, Chapter V. Many texts of nonofficial origin exist.

13 It should be remembered that the "Magic" device intercepted and decoded not merely the important messages but all messages. They still had to be translated into English but there was no way to tell in advance whether a message was of any importance. Because translators were few there were delays in the translation, and because of so much chaff in the heavy flow of interceptions the solid wheat was difficult to separate.

14 See p. 476 above.

15 Reference is again made to the formal findings of the several inquiries listed in n. 12. The Congressional committee majority, having made its final findings on the numerous failings and responsibilities ties for the disaster, concluded its labors (Report, IT. 253-66) with 25 "supervisory, administrative and organizational principles" for Army and Navy study which "strongly impressed" the postwar Chief of Staff's special advisory group on this matter. In a memorandum to the Deputy Chief of Staff on 19 September 1946 this advisory committee, headed by Lt. Gen. Wade H. Haislip, purposely addressing its attention only to the administrative area, declared the analysis of the 25 principles showed "that the deficiencies which existed [in Pearl Harbor defenses on 7 December 1941] were due to the system employed on departmental and theater levels." Study of these principles by all commands and staff divisions was therefore recommended: approval of this suggestion by the current Chief of Staff, General of the Army Eisenhower, was followed by the Secretary of War's formal order for such study throughout the Army, followed by a review of "existing procedure with a view to developing better organization, simpler and more certain command and staff methods." Sec Ltr, TAG to Commanding Generals, 15 Oct 46, sub: Report of the Joint Committee . . . on the Pearl Harbor Attack, AGAO-S-C-M 334 Joint Committee of Congress on Pearl Harbor (8 Oct 46) and accompanying Memo, Gen Haislip for DCofS, 19 Sep 46, sub: Report of the Joint Committee . . . .

35 Message, Miles to G-2 Haw Dept, 27 Nov 41, No. 473, Exhibit 32 (10), p. 1329 of Pearl Harbor Attack, Part 14.

Scrutinizing the WPD draft of that communication he saw the passage "Needed measures for protection against subversive activities should be taken immediately," and struck it out as conflicting with the message's main purpose.

46 In recollections published several years afterwards Donald M. Nelson, wartime chairman of the War Production Board, asserted that at the close of his call at the White House on Tuesday, 2 December, President Roosevelt said, "I wouldn't be a bit surprised if we were at war with Japan by Thursday." Nelson added that on' 3 December in answer to his guarded questioning Secretary Knox, who was "not at all reticent," replied, "We may be at war with the Japs before the month is over . . . . You bet your life its that bad." Donald M. Nelson, Arsenal o/ Democracy (New York: Harcourt, Brace & Co., 1946), pp. 182-83.

47 (1) Pearl Harbor Report, p. 47. (2) Henry L. Stimson and McGeorge Bundy, On Active Service, p- 391. On pp. 391-9z of On Active Service, after an attribution of "major responsibility" for the Pearl Harbor disaster to Admiral Kimmel and General Short, is this passage: "It was true that the War and Navy Departments were not fully efficient in evaluating the information available to them, and of course it was also true that no one in Washington had correctly assessed Japan's intentions and capabilities . . . . Further, Washington had not adequately appreciated the importance of keeping its field commanders fully informed . . . . The men in Washington did not foresee this attack and they did not take the additional action suggested by a retrospective view. But the basic fact remained: the officers at Hawaii had been alerted . . . , unlike other outpost commanders they proved on December 7 to be far from alert."
