Thanks for the responses, I understood that the graves near the CS museum were from earlier than the battle. I admit, as Sgt Schultz would say "I know nothing!" or at least very little. It does seem that if the CS detachment was sent to Middle Boggy to hold the Union advance they would have positioned themselves on one of the major stream crossings. If they were local boys you figure they might know where a large group of men would most likely cross the river/creek.
What I am trying to do is get a ballpark regarding where the 1864 action occurred. (I am a contractor working with the American Battlefield Protection Program and we are trying to get a handle on where the battlefield might be.) I don't think it was at the Depot, but somewhere near Atoka, again I am new at this and defer to folk with greater knowledge. My thought was that if the Texas road was the main road it would have been at that crossing, then again if the new Butterfield stage road was a better road they might have been there, either way they are not really that far apart, at least as the crow flys
I'll have a look at the links and other info. Thanks for your input.
