Harrison claimed that he had won a decisive victory, but some modern historians raise doubts. "In none of the reports from Indian agents, traders, and public officials on the aftermath of Tippecanoe can we find confirmation of the claim that Harrison had won a decisive victory", according to Alfred Cave. The defeat was a setback for Tecumseh's confederacy, although they rebuilt Prophetstown, and native violence increased on the frontier after the battle. Adam Jortner says that the battle was a disaster for both sides, except in strengthening Tenskwatawa's religious movement.
