Glory? Well I'm not aware of any other who had a movie made about them, but black regiments served on most fronts and performed sterling service, even if they didn't get the credit the 54th did. They were at Olustee, Poison Spring, Plymouth, the Crater, as you well know since the south executed so many black prisoners at those battles. They made up whole divisions in the Army of the Potomac.
By the end of the war the black soldiers were 1/3rd of the Union Army.
And don't forget the Stand Watie Legion of 100,000 Invisible Black Confederate Soldiers and Water Carriers. By his lights, any soldier who had been darkened enough by standing guard during an afternoon qualified as "Black", and any officer who brought along a slave to attend to his personal needs had registered them as a full fledged combatant.
Wouldn't Jubal Early be suprised that his female servant and bedmate had enlisted in SW's LO100,000IBCSWC.
the BRAVE & HONORABLE Black men, who fought so well, at the Crater were used as CANNON FODDER, to save the lives of WHITE men. even the REVISIONISTS admit that.
MOST of the units composed of "persons of colour" were used as COMMON LABORERS at the MOST menial of tasks, under the close supervision of WHITE senior NCOs & officers, as the DAMNyankee high command did NOT trust them "to stand & fight". period. end of story.
