A Civil War cannon stands sentinel on the left, its iron barrel aimed toward history, as the rustic log walls of the Snodgrass House emerge from a cathedral of hardwoods in this evocative linen-era view of Chickamauga's most storied landmark — the very spot where Union General George H. Thomas earned the nickname "Rock of Chickamauga" by checking the Confederate advance and saving Rosecrans's shattered army in September 1863. The hand-tinted card bathes the scene in warm greens and soft blues, lending an almost pastoral calm to ground that ran with blood during one of the Civil War's deadliest two-day engagements. Split-rail fencing and a commemorative marker complete the tableau, making this a richly layered souvenir of the Chickamauga and Chattanooga National Military Park — the nation's first and largest military park, established in 1890.
