The Battle of Chickamauga was a bloody battle of the American Civil War between Rosecrans commanding 55,000 Federals and Bragg commanding 70,000 Confederates. It occurred between September the 19th and 20th, 1863. The Federals were badly defeated., They lost 16,000 men and the Confederates 18,000.
Rosecrans was marching on Chattanooga, Bragg slowly retreating and expecting reinforcements before he should decide to give battle. These reinforcements came suddenly and unknown to Rosecrans. Bragg suddenly halted at Chickamauga, and deployed his troops for battle. Rosecrans placed his troops with Thomas on the left, Crittenden in the centre and McCook on the right, along the ChickamaugaCreek. September the 19th the Confederates crossed the creek, and Polk struck Thomas' line. That general speedily returned the assault, thereby confusing Bragg's plan. On September the 20th Thomas was again attacked. He had frequently to call for reinforcements, though he held his position stoutly. Finally General wood, misinterpreting an order, made a false move, which precipitated the Confederate attack upon a weak point in the federal line, and the day was lost. Rosecrans fled to Chattanooga, but Thomas kept fighting until Garfield was sent to summon him. Research Battle of Chickamauga
