A historic marker was unveiled during the event sponsored by the Effingham County Convention and Visitors Bureau.
About 5,000 troops from 67 counties across south Georgia trained at the camp, which operated from February through May of 1862.
Property owner Warren Ratchford said the event was the culmination of 30 years of work by volunteers. His house likely was used as the camp headquarters.
Members of the Camp Davis Sons of Confederate Veterans, dressed in Civil War uniforms, led the activities, which included cannon fire and a rifle volley.
Ladies from the local United Daughters of the Confederacy gave demonstrations, showing how food was prepared during the Civil War.
Three other events are planned by the CVB, the Historic Effingham Society and the Effingham Chamber of Commerce as part of the Georgia Civil War Commission’s 150th commemoration of the Civil War in Georgia.
In 2013, a function will center on the Guyton Confederate Hospital.
In 2014, an event will commemorate the Incident at Ebenezer.
And in 2015, there will be a demonstration of what life was like for families after Sherman’s Army marched through Effingham.
