Profile

Matȟó Wayúhi was a Brulé Lakota chief who signed the Fort Laramie Treaty (1851). He was killed in 1854 when troops from Fort Laramie entered his encampment to arrest a Sioux who had shot a cow belonging to a Mormon emigrant. All 30 troopers in the army detachment were killed, in what would be called the Grattan massacre or "the Mormon Cow War" according to Army Historian S.L.A. Marshall in his book Crimsoned Prairie. Little Thunder took over as chief after his death.
