Many thanks for the detailed and timely replies. A "Sergeant John W. Swartz" was mortally wounded at the battle of Monroe's Crossroads (March 10, 1865) while manning guns with the 10th Wisconsin Light Artillery. No record of an artilleryman with the surname or Swartz or Schwartz (or anything phonetically close to that surname) appears in the 10th Wisconsin rosters at any point during the war. A VA marker was placed on his gravesite in 1924, but in researching other casualties from the battle, I have found that two graves marked as Union soldiers are actually Confederate soldiers. A mix-up in the post-war oral history about the battle and those who died from wounds after the fact led to the mis-identification of the other two burials. Since those graves were not correctly marked, I wanted to see of the SGT Swartz in question was actually a trooper with the 1st Alabama. Since PVT Schwartz with the 1st Alabama survived the war, I'll be following other leads. Although it does not solve the mystery, I certainly appreciate your assistance.

Best,

Charles
