An interesting aside was noted by Jackson concerning Jeb Stuart’s capture of 50 Union troops at the Battle of Falling Waters:
Colonel Stuart reports his capture of an entire company (the Fifteenth Pennsylvania Volunteers), with the exception of the captain. Three, resisting, were killed. He further reports that “one of the enemy was killed by a negro of Captain Carter’s and one of Captain Patrick’s company.” Official Records, Series 1, Vol. 2, p186
In this battle, where only ten Union troops were killed, two were killed by blacks within the Confederate army. This could easily be construed as “uniformed black men in the Confederate ranks,” however, the phrase “a negro of Captain Carter’s” means “a slave of Captain Carter’s.”
Many wealthy Southerners brought slaves with them. They were often called “body servants.” In fact, every Confederate army had an incredible number of slaves with it. They were a great asset to the army and performed a number of menial jobs.
In the case of the slaves of Captains Carter and Patrick, they were personal slaves riding with the cavalry. Clearly they were armed, but there’s no mention as to why. That Jackson recorded it at all is evidence that it was a novelty. However, at this early stage of the war, everything was a novelty.
