On this date in 1863 in North Carolina, the United States Department of War established the Bureau of Colored Troops, to help the Union Army fight the Civil War.

Regiments of colored troops from all states of the nation were reorganized into what became known as the United States Colored Troops (USCT).

In the decades that followed the USCT soldiers fought in the Indian Wars in the American West, where they became known as the Buffalo Soldiers; they received the nickname from Native Americans who compared their hair to the fur of bison.

There is a statue commemorating the soldiers in Maryland.
