During the War of 1812, the British wanted the Indians between the Ohio River and the border of Upper Canada to serve as a buffer against American encroachments. Tecumseh participated in most of the British campaigns. In January 1813, U.S. forces occupied a vulnerable position on the River Raisin, and were attacked by combined British and Indian forces. Losses on the American side, mostly captured, were as high as 800, but thirty-three of the wounded prisoners were killed by the Indians. Rumors quickly exaggerated the numbers killed, and the new battle cry for the U.S. troops became "Remember the Raisin." At the battle of the Thames, William Henry Harrison led an army of five thousand and defeated the remaining British and Indian forces in western Ontario, killing Tecumseh in the midst of the fighting (shown here). Tecumseh's death dignified the end of Indian military power in the Northwest Territory and dissolved any substantial resistance to settlement between the Ohio and Mississippi rivers.
