Hugh Montgomery was an American sea captain during the American Revolutionary War. He was commander of the brig Nancy, chartered to transport military supplies for the Americans. While loading cargo in the Caribbean, he learned that independence had been declared and raised the first American flag in a foreign port, according to his daughter. Returning to Philadelphia, he prevented the seizure of the cargo of gunpowder by British blockaders at the Battle of Turtle Gut Inlet on June 29, 1776. He was later captured by the British and died in 1780 returning from New Providence after his release.
