What happened to Stirman's Battalion after the Surrender at Vicksburg. I know most of the reminants of the Arkansas Regiments from Vicksburg crossed the river and wound up in south Arkansas, and by the Spring of 1864 during the Camden Expedition, most of them are lumped together in a "Brigade" that was commanded by Thomas Pleasant Dockery. The other Arkansas Sharpshooter unit, the 12th Arkansas Infantry Battalion, aka "Rapley's Sharpshooters" wind up with Dockery.

What happened to Stirman's unit?
