"Capture of Fort William and Mary" by Charles Lathrop Parsons recounts a pivotal moment in American history when local Patriots, led by John Langdon, stormed Fort William and Mary in Portsmouth, New Hampshire, on December 14, 1774. This daring raid resulted in the seizure of vital gunpowder, which was distributed throughout the colony in preparation for the impending conflict with Great Britain. The following day, John Sullivan led another assault, capturing cannons that would later play a crucial role in the Battle of Bunker Hill. This account highlights one of the first overt acts of the American Revolutionary War, underscoring themes of bravery, resistance, and the fight for freedom that continue to resonate today.
