Snana (1839–1908), also known as Maggie Brass, was a Mdewakanton Dakota woman who rescued and protected a fourteen-year-old German girl, Mary Schwandt, after she was taken captive during the Dakota War of 1862. She was reunited with Mary Schwandt Schmidt in 1894, leading to a feature article in the St. Paul Pioneer Press. Snana’s narrative of the war, “Narration of a Friendly Sioux,” was edited by historian Return Ira Holcombe and published in 1901. Snana is one of six Dakota "heroes" commemorated by the Faithful Indians’ Monument in Morton, Minnesota.
