Now it's Johann's turn. The SC Confederate Relic Room has only one Union battle flag, a very unique banner. Several regiments of former slaves who lived near Beaufort, South Carolina, fought for the Union forces. (Some islands on the coast had been captured by the US Navy, and slaves on those islands were under Union control.) This is the last surviving flag of one of those regiments, the 2nd SC Volunteers, U.S.
In fact, Harriet Tubman actually marched under this flag at one point! (She was a guide for the 2nd on the Combahee River Raid.) Johann says it's true that many Union soldiers were NOT abolitionists at all - but, he says that every soldier in the 2nd South Carolina Union regiment must have been!
