Well before the 54th Massachusetts stormed Fort Wagner and well before contrabands-turned-soldiers repulsed a Confederate assault at Milliken’s Bend, a regiment of black soldiers, many of them only recently escaped from slavery, fought and bled against Rebel forces, near the Kansas-Missouri border. Far from the central command in Washington D.C., Unionists in the Trans-Mississippi were able to act somewhat independently. This unfortunately resulted in violent guerilla bands called Jayhawkers, who entered into a mutual war of terror with Rebel Bushwhackers. There was a positive, however, the first regiment of black soldiers. This unit, the 1st Kansas Colored, was hastily formed and entered into battle before Lincoln even authorized the creation of black regiments. Their trial of fire was the Battle of Island Mound, a furious skirmish with Confederate partisans in western Missouri.
This battle is mostly known simply for being the first use of a full black regiment in a Civil War battle. There are scant sources on it and actual primary sources can be counted on one hand. I plan to make this an ongoing series that covers the battle history of the 1st Kansas. Not only was it the first true, if unauthorized, black regiment to fight for the Union, it fought in the Trans-Mississippi theatre (my area of focus), and in contrast to the more famous 54th Massachusetts actually had a good win-loss record.
