finally arrived at the scene in the evening and Amherst called a ceasefire for the night. The attack resumed at dawn on 20 August with Williamson, Mohawk and Onondaga all firing on the fort with a combined 50 guns. As the attack progressed, the French guns hit and sank Williamson and Onondaga. Mohawk ran aground under the French cannon, where it sat helpless as it was pounded until out of action. The British batteries on the surrounding islands continued to fire, switching to "hot shot", used to start fires within the fort. The siege continued until 24 August when Pouchot ran out of ammunition for his guns and asked for terms. Aftermath The fighting cost the British 26 killed and 47 wounded (likely excluding militia) to the French losses of around 275 of the original 300 defenders killed or wounded. Pouchot was amongst the wounded. The British could hardly believe that such a small garrison had offered such spirited resistance. After the battle, Amherst's force remained at Fort Lévis for another four days before continuing toward Montreal. The British advance cost Amherst at least 84 more men drowned in the rapids of the St. Lawrence (although Pouchot puts this number at 336). He went on to meet the forces from Quebec and Lake Champlain and completely surrounded Montreal. The three-pronged British forces totaling 17,000 men began to converge on the town, burning villages along the way and prompting mass desertions from the Canadian militia. On 8 September, Montreal was surrendered by New France's governor, the Marquis de Vaudreuil, to avoid further bloodshed. The British renamed Fort Lévis Fort William Augustus. They raised the three vessels sunk during the battle (Williamson, Onondaga and Mohawk) and put them back into service to patrol the waters between the fort and Fort Niagara.
