early May, after Tennessee aligned with the Confederacy, Bate was elected colonel of the 2nd Tennessee Infantry. This unit was quickly dispatched to Virginia, where it was among the forces tasked with guarding the Richmond, Fredericksburg and Potomac Railroad. Bate was present at the Battle of Aquia Creek on May 30, 1861. At the First Battle of Bull Run (First Battle of Manassas) in July 1861, Bate was in the reserve brigade of Theophilus Holmes in the Confederate Army of the Potomac. Bate's unit remained on the Potomac River until February 1862, when, at his request, his unit was transferred to the Western Theater. The 2nd Tennessee was placed under Albert Sidney Johnston's Army of Mississippi, which was conducting operations in the Corinth area. Bate's unit marched north with the Army of Mississippi in its attempt to check Ulysses S. Grant's advance at the Battle of Shiloh in April 1862. Bate was wounded severely in the leg during the first day's fighting, and an Army surgeon told him it would be necessary to amputate his leg to save his life. Bate drew his pistol, threatening to shoot the surgeon, and kept his leg. Although he survived, he was incapacitated for several months, and walked with a limp the rest of his life. Several of Bate's relatives were killed at Shiloh, and his horse was shot out from under him. After spending several months recovering in Columbus, Mississippi, Bate was promoted to brigadier general on October 2, 1862. He was initially given tasks away from the frontlines in North Alabama, but when he demanded a return to action, General Braxton Bragg created an infantry brigade for him to command in the Army of Tennessee. He took part in the Tullahoma Campaign, and saw action at the Battle of Hoover's Gap in June 1863. During this period, Tennessee's Confederate leaders offered Bate the gubernatorial nomination to replace term-limited governor Isham G. Harris, but Bate declined, preferring to stay on the frontlines. At the Battle of Chickamauga, Bate engaged in a skirmish with enemy forces that opened the fighting on the evening of September 18, 1863. In the intense fighting that took place on the following day, three of his horses were shot out from under him. During the reorganization of the Army of Tennessee after this battle, Bate was given command of John C. Breckinridge's division (Breckinridge had been promoted to Corps
