Department of the Northwest

Last updated

The Department of the Northwest was an U.S. Army Department created on 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 received the 27th Iowa Infantry Regiment and from Wisconsin the 25th Wisconsin Infantry Regiment. Both quickly crossed the border to assist with the uprising. [1] 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: the 5th, 6th, 7th, 8th, 9th, and 10th Infantry Regiments, the 1st and 2nd Minnesota Cavalry Regiments, plus the Minnesota Independent Cavalry Battalion (Hatch's Battalion) as well as the 3rd Minnesota Light Artillery Battery. In 1864 companies of the 30th Wisconsin Infantry Regiment saw service in the Minnesota and Dakota Districts, too.

From November 17, 1862, the Department was divided into four districts for a short time. The First District was composed of the Iowa and Dakota Territory, the Second was the vicinity of Fort Snelling, the Third was the vicinity of Fort Ripley and the Fourth was the vicinity of Fort Abercrombie. These last three districts were merged into the District of Minnesota on November 23, 1862. The First District remained until June 1, 1863, when the Dakota Territory was merged into the District of Dakota and Iowa into the District of Iowa. Wisconsin was also a District. The Montana Territory was added to the Department on May 26, 1864. The Department of the Northwest, Department of Kansas, and Department of Missouri were combined to form the Division of Missouri on January 30, 1865. On February 17, 1865, the Montana and Dakota Territories west of 110 degrees west longitude were also attached with Major General Pope, who was elevated to commander of the Division.

The Department of the Northwest through the remainder of the Civil War consisted of the Districts of Wisconsin (under Brig. Gen. Thomas A. Davies), Minnesota (Brig. Gen. Henry H. Sibley) and Iowa (Brig. Gen. Alfred Sully). The Department of the Northwest was merged with the Department of the Missouri on June 27, 1865. In 1866 most of the Department of the Northwest was reorganized as the Department of Dakota.

The Department's forces comprised the Sibley and Sully Expeditions of 1863 as well as Sully's Northwest Indian Expeditions of 1864 and 1865. All of these actions were against the Sioux in the Dakota Territory. [2] [3]

The Dakota War of 1862, also known as the Sioux Uprising, the Dakota Uprising, the Sioux Outbreak of 1862, the Dakota Conflict, or Little Crow's War, was an armed conflict between the United States and several eastern bands of Dakota collectively known as the Santee Sioux. It began on August 18, 1862, when the Dakota, who were facing starvation and displacement, attacked white settlements at the Lower Sioux Agency along the Minnesota River valley in southwest Minnesota. The war lasted for five weeks and resulted in the deaths of hundreds of settlers and the displacement of thousands more. In the aftermath, the Dakota people were exiled from their homelands, forcibly sent to reservations in the Dakotas and Nebraska, and the State of Minnesota confiscated and sold all their remaining land in the state. The war also ended with the largest mass execution in United States history with the hanging of 38 Dakota men.

The area that eventually became the U.S. state of Montana played little direct role in the American Civil War. The closest the Confederate States Army ever came to the area was New Mexico and eastern Kansas, each over a thousand miles away. There was not even an organized territory using "Montana" until the Montana Territory was created on May 26, 1864, three years after the Battle of Fort Sumter. In 1861, the area was divided between the Dakota Territory and the Washington Territory, and in 1863, it was part of the Idaho Territory.
