During the early spring of 1813, scouting parties of Indians allied with the British kept Fort Meigs under close surveillance. In late April, British forces commanded by Brig. Gen. Henry Proctor attacked the fort with an army of 522 British regulars, 462 Canadian militia, and approximately 1,200 Indian warriors. By mid-March 1813, Indians around the camp had become so troublesome that no party could be sent out for fuel, timber, or anything else without being fired upon, and frequently one or two people were killed and as many more taken prisoner.
