On June 28, 1866, the U.S. Congress passed An Act to Increase and Fix the Military Peace Establishment of the United States, which established four segregated African American infantry regiments and two cavalry regiments: the Ninth Cavalry, the Tenth Cavalry, the Thirty-eighth Infantry, the Thirty-ninth Infantry, the Fortieth Infantry, and the Forty-first Infantry. According to the National Park Service the regiments, which became known as the Buffalo Soldier regiments, “were tasked with maintaining peace in the South during Reconstruction (1865-1877), building roads and telegraph lines, escorting U.S. Mail carriers, and protecting homesteaders as well as American Indians on their lands.” The Buffalo Soldier regiments went on to serve the U.S. Army with distinction and honor for close to 90 years.
