Camp William Penn was Pennsylvania's only training camp for African American soldiers during the Civil War and the largest of eighteen such camps in the nation. More than 10,000 men trained there in eleven regiments of U.S. Colored Troops: the 3rd, 6th, 8th, 22nd, 24th, 25th, 32nd, 41st, 43rd, 45th, and 127th. Recruits first arrived on June 26, 1863, and many later fought in Virginia, South Carolina, Florida, and elsewhere. The camp closed on August 14, 1865.
