In North Georgia and South Tennessee, Union and Confederate armies clashed during the fall of 1863 in some of the hardest fighting of the Civil War. The prize was Chattanooga, a key rail center and the gateway to the heart of the Confederacy. In September 1863 the Union Army of the Cumberland was routed at the Battle of Chickamauga and retreated into Chattanooga. Over the next two months Confederate forces besieged the trapped Union army. Finally, in late November 1863 the Union army won a series of battles around Chattanooga and drove the Confederates south into Georgia. We visit Chickamauga Battlefield Military Park often, there is so much History to learn, the drive through with all the Monuments and Museum is Wonderful !!
