In 1810, Tecumseh and Governor Harrison met at Grouseland (Harrison's Vincennes home). Tecumseh demanded nullification of the treaty and the lands returned to the tribes. Harrison insisted each tribe had individual and separate arrangements with the United States, ridiculing the idea of common ownership of lands. Tecumseh stated his position clearly: he would serve the American loyally if the lands were returned; if not he would seek an alliance with the British. As early as 1810, British agents had sought to secure an alliance with Tecumseh, who was reluctant to ally with them because he recognized that they used the tribes to fight their wars on the frontier. Yet he travelled to Canada to meet with the British and Canadians in November 1810, after securing alliances with the Potawatomi and the Odawa as well as contacting the Iowa.
