Simon Anawangmani (He Who Goes Galloping Along) was born in about 1808. A Dakota of the Wahpeton band, he was educated at Dr. Williamson's Lac Qui Parle mission. Although he had an early reputation as a warrior, he was one of the earliest Dakotas to convert to Christianity, and was later known for his prominence in the Hazelwood church, where he was an elder. He was friendly to the whites during the Dakota uprising of 1862. He protected the Hazelwood missionaries and distinguished himself by rescuing a German captive, Mrs. Neuman, and her three children. In 1863 he was in the Dakota camp at Ft. Snelling. Later that year he joined Sibley's army as a scout, serving until 1865. In 1866 he was licensed to preach in the Presbyterian church. After the Sisseton reservation was established in 1867, he settled on land near the agency. He died there in 1891. His name appears on a monument erected by the Minnesota Valley Historical Society at Morton, MN. The monument is in commemoration of the Dakotas who saved lives of the whites during the 1862 uprising.
