This brings out a possible interesting difference between the US Army and the CSA Army. I know of at least one

instance of a black body servant, Dan Hayes, who accompanied Lt. James Madison Boyd, Co. D, 40th Mississippi

into battle (Peach Tree Creek, et al) and after the War received a pension from the State of Mississippi. Might this mean

some Southern States provided pensions to blacks who served and northern states or the US Government did not?

I do not know. Do you MoFed?
