The Battle of the Thames, fought on October 5, 1813, was a decisive victory for the United States during the War of 1812.1

Following the U.S. naval success at the Battle of Lake Erie, British Brigadier General Henry A. Procter retreated from Detroit across the Ontario peninsula. He was pursued by approximately 3,500 U.S. troops led by Major General William Henry Harrison.1

The opposing forces met near the Thames River in present-day Ontario, Canada. The British force, consisting of about 600 regulars and 1,000 Indian allies under the Shawnee leader Tecumseh, was significantly outnumbered and quickly defeated.1

The battle resulted in the death of Tecumseh, which effectively destroyed his intertribal alliance and broke Indian resistance in the Ohio and Indiana territories. Following the defeat, most tribes abandoned their association with the British, and the U.S. victory helped consolidate American control over the Northwest.12
