next day, Scorpion came into view and anchored about away, but appeared not to have heard any of the fight. At dawn on 6 September, Worsley set sail towards Scorpion in Tigress, under American colours and with most of his men below decks or concealed under their greatcoats. The unsuspecting crew of Scorpion could be seen scrubbing the deck. Worsley approached to within few yards of the Scorpion and then fired a volley of muskets and Tigresss 24-pounder cannon. As the vessels came into contact, Worsley's men swarmed aboard the American vessel. The surprised Americans made little resistance. Two Americans were killed and two wounded. There were no British casualties. Scorpion (but not Tigress) had boarding nettings rigged and might have been able to fight off a boarding attempt from small boats, but not from a vessel of equal size. Aftermath The captured Scorpion and Tigress were renamed Confiance and Surprise. They sailed at once for the Nottawasaga. On hearing of the loss of Nancy, Lieutenant General Sir Gordon Drummond, the Lieutenant Governor of Upper Canada, had urgently dispatched batteaux and extra supplies to the Nottawasaga. Confiance and Surprise returned to Mackinac at the start of October with sufficient provisions to keep the garrison of Mackinac supplied until the end of the war. The British planned to build a frigate and other vessels at Penetanguishene on Matchedash Bay in 1815, which would have further reinforced the British advantage in the area. The end of the war put a halt to most of this construction (although the armed schooner Tecumseth and the unarmed transport vessel Bee were built in 1816 and a naval base was opened at Penetanguishene in 1817). However, all British shipbuilding efforts on the lakes had to compete for resources against those on Lake Ontario, which were being surpassed by the Americans at Sackets Harbor. Another major problem was lack of additional land transportation for such purposes. At the end of the war, some British officers (including McDouall) and Canadians objected to handing back Prairie du Chien and especially Mackinac under the terms of the Treaty of Ghent. However, the Americans retained the captured post at Fort Malden, near Amherstburg, until the British complied with the treaty. Results Although small in scale, the British and Ojibwa Indian successes on Lake Huron were vital, given the remoteness and sparse population of the theatre. Some historians maintain that the expedition
