During the night, John Morfin collapses and asks Henry Goodsir to kill him. The rest of the camp wakes up and Morfin takes the rifle from Pvt. William Pilkington and points it at Crozier. James Fitzjames orders Morfin to lower his weapon and Morfin shoots towards him before being shot dead by Tozer.
