Thanks to this great website I just was informed that my gg grandfather Pvt. Albert Poston Davis was killed in action with the 29th Reg. Texas Calvary, Co. F, at Greenleaf Prairie, Cherokee Nation (OK) on 16 June 1863. I sent for his Veteran's Service Record today. Now I would like to know more about the battle at Greenleaf Prairie and where he might be buried. Thanks for any help you can give me!
