A detailed, illustrated account of a key, narrow victory for the Union.By the Autumn of 1863 the Confederacy was in dire straits. In a colossal gamble, Confederate President Jefferson Davis stripped forces from all the major Confederate armies to reinforce the Army of Tennessee in a last ditch attempt to crush the Union. On 19th September the Confederates attacked the Union army along Chickamauga creek south of Chattanooga.On the second day of bloody fighting the entire Union right collapsed and the army retreated headlong for Chattanooga, all except General George H. Thomas’ Corps who fought on doggedly until nightfall delaying the confederate advance, saving the Union and earning his fame as the "Rock of Chickamauga".
