The Regular Army Before the Civil War, 1845–1860 is part of the U.S. Army Campaigns of the Civil War series. This short study covers the fifteen years preceding the outbreak of the Civil War, to include the Mexican War; conflicts with Indian tribes; and exploration and governance of the vast American West. It was during this time that many young officers, who would later become senior civilian and military leaders on both sides during the Civil War, got their first taste of action.
