It was common policy for Confederates soldiers in USA civil war to kill surrendering or surrendered black union soldiers and their white officers during and after battles. Luckily they showed rare mercy for this absolute chad.

This was about aftermath of Battle of the Crater of USA civil war. Despite white officer POWs getting of easy battle itself was also single largest massacre of black union troops of the war when 500 of them got stuck in a crater made by mine blown under CSA lines and were massacred without mercy by CSA soldiers.

Regiment that Dobbs belonged to, 19th US Colored troops, was later one of the first to enter CSA capital Richmond at the end of the war.
