What tribe what American Horse a part of?
John Wallace Crawford John Wallace ("Captain Jack)" Crawford (1847–1917), known as "The Poet Scout", was an American adventurer, educator, and author. "Captain Jack" was a master storyteller about the Wild West and is known in American history as one of the most popular performers in the late nineteenth century. His daring ride of 350 miles in six days to carry dispatches to Fort Laramie for the "New York Herald", to tell the news of the great victory by Gen. George Crook against the village of Chief American Horse at the Battle of Slim Buttes during the Great Sioux War of 1876-1877, made him a national celebrity.
Primitive markings Primitive markings are a group of hair coat markings and qualities seen in several equine species, including horses, donkeys, and asses. In horses, they are associated with primitive breeds, though not limited to such breeds. The markings are particularly associated with the dun coat color family. All dun horses possess at least the dorsal stripe, but the presence of the other primitive markings varies. Other common markings may include horizontal striping on the legs, transverse striping across the shoulders, and lighter guard hairs along the edges of a dark mane and tail.
