The Confederate States Marine Corps (CSMC) was a branch of the Confederate States armed forces during the American Civil War. It was established on March 16, 1861. The CSMC's manpower was initially authorized to include one major, one quartermaster sergeant, and 600 men divided into six companies of 100 marines each. This was increased on May 20, 1861 raising the rank of officers and adding more men. The organization of the corps began at Montgomery, Alabama. It was completed at Richmond, Virginia, when the capital of the Confederate States of America was moved there. The CSMC headquarters and main training facilities remained in Richmond, Virginia throughout the war. It was located at Camp Beall on Drewry's Bluff and at the Gosport Shipyard in Portsmouth, Virginia. The last CSMC unit surrendered on April 9, 1865, with the Confederacy itself surrendering a month later.
