On August 29, the Mohawks at the Mercier Bridge negotiated an end to their protest blockade with Lieutenant-Colonel Robin Gagnon, the "Van Doo" commander who had been responsible for the south shore of the St. Lawrence River during the crisis. This stand-down eventually contributed to the resolution of the original siege on the Kahnawake reserve, and on September 26 the Mohawks there dismantled and burned some of their weapons. During the surrender, as the military began arresting land defenders and some began to flee, 14-year-old Waneek Horn-Miller was stabbed near the heart by a Canadian bayonet, and nearly died.
