Yielding to pressure from the U.S. government in 1851, the Eastern Dakota (Eastern Sioux) sold 35 million acres of their land across southern and western Minnesota. The Dakota moved onto a small reservation along the Minnesota River, stretching from just north of New Ulm to today’s South Dakota border.

In 1853, the U.S. military started construction on Fort Ridgely, near the southern border of the new reservation and northwest of the German settlement of New Ulm. The fort was designed as a police station to keep peace as settlers poured into the former Dakota lands.

Nine years later, unkept promises by the U.S. government, nefarious practices by fur traders and crop failure all helped create tensions that erupted into the U.S.-Dakota war in August 1862. Dakota forces attacked the fort twice-on Aug. 20 and Aug. 22. The fort that had been a training base and staging ground for Civil War volunteers suddenly became one of the few military forts west of the Mississippi to withstand a direct assault. Fort Ridgely’s 280 military and civilian defenders held out until Army reinforcements ended the siege.
