Existing comment: Who Fought Here?
For the Union side, the primary fighting force at Chattanooga was the blue-clad Army of the Cumberland. For the Confederates, it was the gray-clad Army of Tennessee.
The men in the Union Army of the Cumberland -- almost 60,000 strong in early September -- came mostly from Ohio, Indiana, and Illinois. During the campaign, they were reinforced by 20,000 men from the Army of the Potomac and 17,000 from the Army of the Tennessee.
At the outset of Chattanooga campaign, the Army of the Cumberland was commanded by Gen. William Rosecrans. He was replaced by Gen. George H. Thomas in October, when Gen. Ulysses S. Grant took charge of all Union troops in the region.
The Confederate Army of Tennessee consisted of 45,000 men at the outset of the struggle for Chattanooga. Many came from Tennessee, Alabama, Mississippi, and Arkansas. Early in the campaign, troop strength was raised to over 60,000 by reinforcements from other Western front and the Army of Northern Virginia.
The Army of Tennessee was led by Gen. Braxton Bragg. He remained in control to the bitter end of this campaign.
