Battle of the Thames
Roundhead died of natural causes shortly before the Battle of the Thames on October 5, 1813. On Roundhead's death, General Procter wrote in a letter dated October 23, 1813, "The Indian cause and ours experienced a serious loss in the death of Round Head." For years, Roundhead, who was a staunch supporter of Tecumseh, feuded with other Wyandot clans who supported Tarhe's pro-American stance. Once Tecumseh's forces were defeated at the Battle of the Thames, the division between the Wyandot ended. They began negotiations for peace with the Americans.
