The siege of Fort Mifflin or the siege of Mud Island Fort, which took place from September 26 to November 16, 1777, saw British land batteries commanded by Captain John Montresor and a British naval squadron under Vice Admiral Lord Richard Howe attempt to capture an American fort in the Delaware River that was commanded by Lieutenant Colonel Samuel Smith. The operation finally succeeded after Smith was wounded. His successor, Major Simeon Thayer, subsequently evacuated the fort on the night of November 15, enabling British troops to occupy the place the following morning. After General Sir William Howe's British-Hessian army occupied Philadelphia, Pennsylvania on September 26, 1777, it became necessary to supply his troops. Fort Mifflin on Mud Island in the middle of the Delaware and Fort Mercer at Red Bank, New Jersey, together with river obstructions and a small flotilla under Commodore John Hazelwood prevented the Royal Navy from shipping provisions into the city.
