Sioux and Cheyenne warriors made on this day one of their many attacks on railroad building works in western Kansas that were happening with regularity for months during the summer of 1867. This attack was on the Kansas Pacific works near Fort Harker at Kanapolis in present-day Ellsworth County and took the life of one worker. J.D. Perry, the president of the Kansas Pacific, complained to military authorities claiming that attacks were occurring almost daily and that a thousand workers had fled into Fort Harker and were refusing to return to the exposed engineering camps.
