My GGGrandfathers grave is marked with a CSA stone that mentions the "Mexican border skirmish". It also lists the group he was with but cant remember the name(I dont have it in front of me)but I think it was the 1st Texas infantry.(?) His marked grave is in Coryell county, Gatesville Texas. Actually on the northeastern edge of Fort Hood, not too far from the Leon River.
Does anybody know anything about this unit or skirmish?
