The Battle of Wood Lake occurred on September 23, 1862, and was the final battle in the Dakota War of 1862. The two-hour battle, which actually took place at nearby Lone Tree Lake, was a decisive victory for the U.S. forces led by Colonel Henry Hastings Sibley. With heavy casualties inflicted on the Dakota forces led by Chief Little Crow, the "hostile" Dakota warriors dispersed. Little Crow and 150 followers fled for the northern plains, while other Mdewakantons quietly joined the "friendly" Dakota camp started by the Sisseton and Wahpeton bands, which would soon become known as Camp Release.
