Chickamauga & Chattanooga National Military Park presents Alexander's Artillery Battalion On Lookout Mountain - Living History Artillery Demonstrations program on Saturday, Aug. 15 at 11 a.m., 2 p.m. and 3 p.m. Each program is 30 minutes. Fees apply

Officials said, "Colonel Edward Porter Alexander’s Confederate artillery moved to the summit of Lookout Mountain in the aftermath of the Battle of Chickamauga, as General Braxton Bragg’s victorious forces laid siege to Chattanooga. Their goal was to compel Union troops under General William Rosecrans to surrender or abandon the city.

The key to this effort rested with the guns on Lookout Mountain, which commanded the Tennessee River below, the only practical route Rosecrans had for bringing in supplies.

"Until the Cracker Line opened in late October, these artillery positions made life difficult for the Union army. To learn more about the vital role played by these men and their guns, and to see and hear what the war may have sounded like from Lookout Mountain, join us for this special program."

Entrance fees to enter Point Park, on Lookout Mountain, are $10/adult (ages 16 and older); children are free. (ages 15 and younger).
