CONFEDERATE GEORGIA TROOPS

2nd Regiment, Georgia Cavalry

2nd Cavalry Regiment, assembled at Albany, Georgia, in February, 1862, contained men from Randolph, Dougherty, Clayton, Marion, Fulton, and Decatur counties. It moved to Chattanooga and after skirmishing in Tennessee was placed in Forrest's, Wharton's, J.J. Morrison's, Iverson's, and C.C. Crews' Brigade. The regiment participated in various conflicts such as Perryville, Murfreesboro, Chickamauga, Philadelphia, Campbell's Station, Bean's Station, and Mossy Creek. Later it was involved in the Atlanta Campaign, the defense of Savannah, and the campaign of the Carolinas. On April 26, 1865, the 2nd Cavalry surrendered with only 18 men. The field officers were Colonels Charles C. Crews and William J. Lawton; Lieutenant Colonels James E. Dunlop, Arthur Hood, and Francis M. Ison; and Majors James W. Mayo and C.A. Whaley.

I did find this soldier ??????

He is a match to your John or J.J. but as you see he is in the 2nd Infantry not 2nd Cavalry. I don't know if this is of any help but I hope so.

Thanks,
Gary D. Bray
