On September 11, RCMP detonated an explosive device buried in an access road to the camp, heavily damaging a supply truck being driven by occupiers. The incident resulted in a firefight that made use of the military-loaned Armoured Personnel Carriers (APCs). Non-indigenous occupier Suniva Bronson was shot in the arm during the shootout and would be the only injury in the extensive exchange of bullets. On the following day, an unarmed man crossing a field designated as a no-shoot zone was shot at by police snipers. Police later admitted to this mistake. The standoff ended peacefully on September 17 when the few remaining occupiers left the site under the guidance of medicine man, John Stevens.
