"Henry McCarty, of Northfield, age 24, enlisted 8/27/62, and mustered in as a private in Co. H, 11th Vermont Infantry on 9/1/62. He was taken prisoner 11/12/64, and joined the CSA while a prisoner."

What's the term for Galvanised Yankee, in reverse? This name drew my attention. Do you suppose he might have been any kin to William F. Bonney, AKA Billy the Kid, whose real name was Henry McCarty? Intersting. Stan
