Outmaneuvered

or nine months beginning in January 1863, General Braxton Bragg's Confederate Army of Tennessee was outmaneuvered by Union General William Rosecrans and his Army of the Cumberland. Bragg, forced to abandon middle Tennessee, retreated to Chattanooga. In early September, concerned about his southern supply line, Bragg again moved his Army. This time he moved about 12 miles southeast of Chattanooga to an area around Chickamauga Creek.

The Tide Turns

With reinforcements from The Army of Northern Virginia under General Longstreet, the tide had turned for Bragg and he went on the offensive. Missing opportunities to attack Rosecrans when he was vulnerable, Bragg finally attacked on the morning of September 19, 1863.

The Gap

No advantage was achieved by either side on the 19th. The deciding event occurred at 11:00 am on the 20th. Union General Thomas Wood received orders to move his division. The orders from Rosecrans, however, were based on incorrect information. Wood probably knew this but earlier that morning he had been publicly scolded by Rosecrans for not promptly following orders. Probably because of this, Wood blindly followed the orders leaving a large gap in the Union line. Coincidentally, Longstreet had planned an attack on that position. The attack was launched just minutes after Wood's departure.

Through the gap poured 11,000 screaming Confederates. In just minutes, the entire Union right wing broke and retreated in disarray toward Chattanooga. But the Union left wing, under George Thomas, remained intact. Thomas' men made a stand on Snodgrass Hill allowing Rosecrans' Army to escape to Chattanooga. This earned Thomas the nickname "Rock of Chickamauga".

This was a costly Confederate victory. After the battle, the Union's Army of the Cumberland retreated into Chattanooga. Rather than attacking, Bragg, ignoring the advice of his top commanders, decided to lay siege and starve the Union forces into submission.
