American settlers grew uneasy as Indians flocked to Greenville. In 1806 and 1807, Tecumseh and Blue Jacket traveled to Chillicothe, the capital of the new U.S. state of Ohio, to reassure the governor that Greenville posed no threat. Rumors of war between the United States and Great Britain followed the "Chesapeake" incident of June 1807. To escape the rising tensions, Tecumseh and the Prophet decided to move west to a more secure location, further from American forts and closer to potential western Indian allies.
