while Howard Peckham gives a figure of 50 Americans killed. Aftermath Scattered fragments of the American army made their way overland on the northern shore to Berthier, where they crossed over to Sorel. Some did not return until June 11. Sullivan, who counted 2,500 effective troops under his command, at first wanted to make a stand at Sorel, but smallpox, desertions, and word that the British fleet was again under sail to come upriver convinced him it was time to retreat. By June 17, the Continental Army had left the province; but not before it had attempted to burn Montreal, as well as destroying Fort Saint-Jean and any boats of military value capable of navigating Lake Champlain. Carleton ordered most of the British army to sail upriver toward Sorel on June 9, but they did not actually leave until he joined them on June 13. A detachment of 1200 men under Fraser marched up the northern shore toward Berthier and Montreal. The British fleet arrived at Sorel late on the 14th; the Americans had left there just that morning. Elements of the British army entered Montreal on June 17, and also arrived at Fort Saint-Jean in time to see the last Americans (the very last one reported to be Benedict Arnold) push away from its burning remnants. The captives were treated quite generously by Carleton. Although the conditions of their imprisonment were not always good, he provided them with clothing, and eventually had all but the officers transported to New York and released. Legacy A site near the Le Jeune bridge was designated a National Historic Site of Canada in 1920 in order to commemorate the battle. There are three plaques in the city of Trois-Rivières commemorating aspects of the battle. A plaque honouring the British participants was placed at the National Historic Site by the Historic Sites and Monuments Board of Canada. A plaque honouring the American dead was placed in the Parc Champlain by the Daughters of the American Revolution in August 1985. The third plaque honours Antoine Gauthier for his role in misleading the American troops. During the American retreat from Quebec, and in this battle, wounded soldiers were treated at the Ursuline convent in Trois-Rivières. Congress never authorized payment for these services and the convent has retained the bill. By the early 21st century, the original bill of about £26 was estimated to be equivalent to
