The Battle of Tippecanoe (/ˌtɪpikəˈnuː/ TIP-ee-kə-NOO) was fought on November 7, 1811, near present-day Lafayette, Indiana between American forces led by Governor William Henry Harrison of the Indiana Territory and Native American warriors associated with the Shawnee leader Tecumseh. Tecumseh and his brother Tenskwatawa (commonly known as "The Prophet") were leaders of a confederacy of Native Americans from various tribes that opposed US expansion into Native territory. As tensions and violence increased, Governor Harrison marched with an army of about 1,000 men to disperse the confederacy's headquarters at Prophetstown, near the confluence of the Tippecanoe and Wabash Rivers.
