Row of historical markers -- smaller than the park's large monuments -- at the Chickamauga portion of the Chickamauga & Chattanooga National Military Park in Georgia. In November 1863, Union and Confederate forces fought for control of Chattanooga, Tennessee, a railroad hub known as the "Gateway to the Deep South." The Confederates had been victorious two months earlier at nearby Chickamauga, Georgia, in September. However, Union troops prevailed at Chickamauga. Photo by Carol Highsmith, 2017.
