In August 1862, violence swept across Minnesota in what became known as the “Minnesota Sioux Uprising.” It hit fast and close. Along the Minnesota River valley, families fled farms and small towns with little warning.

New Ulm was attacked on August 19, and panic spread across southern Minnesota. Fort Ridgely was assaulted on August 20 and again on August 22. Settlers crowded into towns or ran east, leaving wide stretches of countryside empty.
On September 6, the War Department created the Department of the Northwest and placed Major General John Pope in command, with headquarters at St. Paul. Pope’s orders were clear: restore order and end the violence. His first problem was also clear. He needed troops.
The Civil War made that difficult. Regular army units were tied down in the South and East. Pope had to pull help from nearby states, even if the men were brand new. Iowa responded with the 27th Iowa Volunteer Infantry.
