Postbellum
The USCT was disbanded in the fall of 1865. In 1867 the Regular Army was set at 10 regiments of cavalry and 45 regiments of infantry. The Army was authorized to raise two regiments of black cavalry (the 9th and 10th (Colored) Cavalry) and four regiments of black infantry (the 38th, 39th, 40th, and 41st (Colored) Infantry), who were mostly drawn from USCT veterans. In 1869 the Regular Army was kept at 10 regiments of cavalry but cut to 25 regiments of Infantry, reducing the black complement to two regiments (the 24th and 25th (Colored) Infantry).
