I am looking for any info on a POW, Warrenton Wigginton (various spellings) who was captured in hospital at Vicksburg and sent to Mobile Bay via New Orleans on the Steamer St. Maurice. The Surgeon in Charge was Jno. C. Merrill. According to his widow's pension, he died in transit to Mobile Bay. Any info on this soldier including where he might be buried if this is true, would be greatly appreciated. thanks!
