Although soldiers destroyed one Arapaho village and established Fort Connor to protect gold miners on the Bozeman Trail, the expedition is considered a failure because it failed to defeat the Indians and invade their lands.

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.
The Battle of Birch Coulee occurred September 2–3, 1862 and resulted in the heaviest casualties suffered by U.S. forces during the Dakota War of 1862. The battle occurred after a group of Dakota warriors followed a U.S. burial expedition, including volunteer infantry, mounted guards and civilians, to an exposed plain where they were setting up camp. That night, 200 Dakota soldiers surrounded the camp and ambushed the Birch Coulee campsite in the early morning, commencing a siege that lasted for over 30 hours, until the arrival of reinforcements and artillery led by Colonel Henry Hastings Sibley.
The Surrender at Camp Release was the final act in the Dakota War of 1862. After the Battle of Wood Lake, Colonel Henry Hastings Sibley had considered pursuing the retreating Sioux, but he realized he did not have the resources for a vigorous pursuit. Furthermore, he was aware that Chief Little Crow had been losing support and was in contact with several Mdewakanton chiefs who had signaled their opposition to further conflict.

The Department of the Northwest was an U.S. Army Department created September 6, 1862 to put down the Sioux uprising in Minnesota. Major General John Pope was made commander of the Department. At the end of the Civil War the Department was redesignated the Department of Dakota. Immediately upon arriving in St. Paul General Pope sent letters to the Governors of Iowa and Wisconsin for additional troops to assist the 5th Minnesota Infantry Regiment. From Iowa he got the 27th Iowa Infantry Regiment and from Wisconsin he received the 25th Wisconsin Infantry Regiment. Both quickly crossed the border to assist with the uprising. The 25th Wisconsin was in Minnesota three months and the 27th Iowa was there a month before both headed south. After they departed, the Minnesota District would be garrisoned by Minnesota units: 5th, 6th, 7th, 8th, 9th, 10th Infantry Regiments, 1st and 2nd Minnesota Cavalry Regiments plus Minnesota Independent Cavalry Battalion as well as the 3rd Minnesota Light Artillery Battery.
