Southern slave Robert Smalls steals the steamboat Planter, spirits it through Confederate lines and hands it to the United States Navy, who quickly commission it as the gunboat USS Planter and appoint Smalls as captain, thus making him the first black man to command a United States ship.

Robert Smalls was an American politician who was born into slavery in Beaufort, South Carolina. During the American Civil War, the still enslaved Smalls commandeered a Confederate transport ship in Charleston Harbor and sailed it from the Confederate-controlled waters of the harbor to the U.S. blockade that surrounded it. He then piloted the ship to the Union-controlled enclave in Beaufort–Port Royal–Hilton Head area, where it became a Union warship. In the process, he freed himself, his crew, and their families. His example and persuasion helped convince President Abraham Lincoln to accept African-American soldiers into the Union Army.
