The Battle of Wood Lake in Minnesota on September 23rd 1862 was the beginning of the end of the Minnesota Sioux uprising.
Colonel Henry Hastings Sibley set out on September 19th 1862 with about 1,400 volunteers; among them 300 members of the 3rd Minnesota who were on parole after being captured by the Confederates at Murfreesboro. They left from Fort Ridgely to put down the Santee Sioux who were raiding in Minnesota. The soliders were nearly ambushed by 700 Indians under Chief Little Crow on September 23rd 1862 as the force approached Wood Lake. Sibley’s men were saved from ambush by some of the soldiers from the 3rd Minnesota Regiment who were looking for food. The Sioux shot at them, they returned the fire, and the sound of battle brought the rest of Sibley’s troops into the fray. The fight went on for two hours. US forces inflicted heavy casualties on the Sioux, winning the day.
Sibley was promoted to Brigadier General for his actions during this command. The battle led to the release of white captives held by the Sioux, who had been taken during the Sioux uprising.
