I had a GGUncle, Joseph Hammons (sometimes spelled Hamon) in company G of the 1st Georgia Cavalry. They were in the Army of Tennessee and, sometimes, in the Dept. of East Tennessee. He was sick for part of 1863 and sent to a Richmond hospital. Is there any way I can determine the dates he was with his unit? Would like to find out what campaigns, battles, encampments he would have been with his regiment. Thanks, Jeff.
