It was June 27, 1874 at Adobe Walls on the Canadian River in the Texas panhandle. Young Billy Dixon and 27 Buffalo hunters were suddenly surrounded by more than 500 Kiowa and Comanche warriors. The Kiowa medicine man told the warriors that his medicine made them invisible to the bullets of the white eyes. When Dixon fired his Sharps sporting rifle and knocked a Kiowa from his horse at 1538 yards (7/8 mile), the Indians departed with haste.
