Wrong name on the image?
Co "D", 2nd Alabama Regiment, organized as the "Suggsville Greys". It belonged to the Alabama Volunteer Corps, and we saw clearly is not a regulation AVC uniform.
Capt Stephen B Cleveland recruited Co "D", 2nd Alabama Regiment, resigned, and raised another company called the "Clarke County Rangers." It became Co "I", Wirt Adams Mississippi Cavalry.
With that information in hand, can you connect the dots?
