19 June 1869; Wallace, Kansas: Near the end of the railroad tracks at Sheridan, Cheyenne Dog Soldiers attacked a surveying party escorted by a detachment of Company E, 7th Cavalry. One Indian rode up so close to surveyor Howard Schuyler that Schuyler touched him with the muzzle of his gun as he fired. Schuyler's horse was shot four times and collapsed as Schuyler reached the surveyors' camp.
Two surveyors, including Schuyler, were wounded. Two soldiers were also wounded, while reportedly 4 Indians were killed and 12 wounded.
