Six Nations Legacy Consortium War of 1812 General Hull's Freakout 1812 "I have done what my conscience directed. I have saved Detroit and the Territory from the horrors of an Indian massacre." U.S. General William Hull who surrendered Fort Detroit to General Isaac Brock, 1812 Hull Surrendering Fort Detroit On July 12, 1812 an American invasion of Canada began near Fort Detroit. U.S. Brigadier General William Hull sent notice to Grand River that our settlements and families would not be disturbed if our warriors would remain at home. The Americans promised they would respect our lands and rights. He also sent a proclamation to the Canadians that threaten "a war of extermination" against anyone opposing the American invasion or associating with the warriors. The Grand River people were confused and divided over whether or not they could trust the Americans. Despite Norton's best efforts only 100 Grand River warriors agreed to go to Detroit. Along the way, doubts increased and about half of those warriors returned home. Tehcumtheh, on the other hand, had a force of 3,000 warriors at his command. He intercepted a message from General Hull noting his fear of being captured by the warriors. General Brock used that fear to his advantage. First he sent a bogus document stating that 5,000 warriors were about to descend on Detroit. After shelling the force and making a show of his Native allies, Brock informed Hull that the only way he could be protected from the wrath of the warriors would be to surrender. Hull did so without conferring with his fellow officers and was later found guilty of cowardice and neglect of duty.
