President Lincoln forbade further retaliation for the murder of captured colored troops after the initial expedient field hangings of maybe two dozen captured CSA immediately following Fort Pillow, and made it official policy not to retaliate for further murders of colored troops. The only postwar charges against the CSA concerned Union white troops. Colored troops didn't count by official Union policy.
I hadn't heard about the 6th Tennesee Cavalry. Can you post a link about the incident? Some of those Southern Unionist vs. Southern Confederate battles got really mean for local reasons.
There are several accounts of the
Hurst Nation and the 6th Tennessee Cavalry, U.S.A., on the Internet. Alex Haley was working on this specific atrocity committed by the 6th Tennessee when he passed away and the project went senescent.
Thud...F-105....my Father destroyed Colonel Miller's nose film after he strafed Haiphong Harbor and the Russian ships...Little personal history. Dad was the crew chief for Miller's F-105.
