How did the buffalo soldiers affect the Texas frontier

The Buffalo Soldiers comprised one of the most interesting military aggregations in post-war Texas. On July 28, 1866, the U. S. Congress authorized six regiments of black troops - two of cavalry and four of infantry - to be added to the U. S. Army. The nickname "Buffalo Soldiers" was given by Indians, who thought that the tightly curled hair of the black soldiers resembled the curly hair on a bison's face. Since the bison was revered by the Indians, the nickname was considered a term of respect, and the Buffalo Soldiers proudly featured a bison on their regimental crest.
