In case you weren't there: Johnston had his Confederate troops entrenched to protect the Western & Atlantic Railroad, the supply link to Atlanta. On the morning of June 27, 1864, Sherman let loose artillery bombardment before sending in the Union troops, according to historians. They made some headway overrunning Confederate pickets south of the Burnt Hickory Road, but attacking an enemy that is dug-in is tough business. The fight was over by noon. Sherman suffered three quarters of the casualties.

As for this weekend, you can check out the schedule below. It includes a guided hike along with artillery and infantry demonstrations.
