When the USS Monitor capsized, 63 of the crewmen survived the event, but 16 lost their lives, counting two men buried in the turret of the ship. There were seven black men aboard the vessel, some freed and some escaped slaves, all serving as sailors. They were: William Nichols, Siah Carter, William Scott, Robert Howard, Edward Cann, Daniel Moore and William Jeffrey.
