(Apparently, only three out of eleven boats ultimately reached Mackinac.) Having rowed and paddled , Worsley encountered the two gunboats in the Detour on 24 August but was able to turn aside without being spotted. He concealed the batteaux at a secluded bay and his whole party reached Mackinac Island in the canoe on 1 September. At one point, he had passed within only a few yards of one of the gunboats at night, without being detected. Capture of the gunboats Supplies at Mackinac had run so short that McDouall's soldiers were on half rations, and he had even killed some horses to feed the Native Americans. Worsley asked McDouall for reinforcements to be used to attack the gunboats. He was given four large boats and 60 men of the Royal Newfoundland Fencibles, all of whom were accustomed to serving as marines. Lieutenants Bulger, Armstrong and Raderhurst of the Royal Newfoundland commanded three of the boats. Worsley commanded the other, which held 17 of his sailors. Bulger's boat was armed with a 3-pounder gun railing gun, removed earlier from Nancy and Worsley's with a 6-pounder gun, also from the Nancy. Two hundred Ojibwa from Manitoulin Island, led by Chief Assiginack, followed them in nineteen canoes in case any warriors were fighting for the Americans. Late on 2 September, the boats and canoes landed on Drummond Island. Worsley and Livingston went scouting the next day, and spotted Tigress anchored a few miles away. That night, the British and Ojibwa set out towards the gunboat. Except for Lieutenant Robert Dickson of the Indian Department and three chiefs, the Native Americans were told to wait away. In the early hours of 4 September, Worsley's four boats approached Tigress silently. The crew of the gunboat (thirty-one sailors and soldiers under Sailing Master Stephen Champlin) spotted them too late, and their fire missed. Before they could reload, Worsley's and Armstrong's boats were alongside the starboard side of the gunboat, and Bulger's and Raderhorst's boats were to port. The Newfoundlanders and Worsley's sailors swarmed on board the gunboat and overpowered the Americans after a sharp struggle. Three Americans were killed and five wounded (including Champlin and both his junior officers). Three British were killed and seven, including Lieutenant Bulger, wounded. Livingston set off to find Scorpion, and returned two hours later to report that the gunboat was approaching. The captured Americans were hastily sent ashore. The
