In the midst of the 1940 presidential campaign prominent black leaders complained bitterly to President Franklin D. Roosevelt about the limited number of black units. Under political pressure the Army activated the 2nd Cavalry Division at Fort Riley, Kansas, on 1 April 1941, with one white and one black brigade. The black brigade, the 4th Cavalry Brigade was activated during February 1941 with the 9th Cavalry Regiment and 10th Cavalry Regiment, the 'Buffalo Soldiers,' as its cavalry regiments. In addition, a further black cavalry regiment, the 27th Cavalry Regiment (Colored), 2nd Cavalry Division, was also activated in April 1941.
