“The latter author points out that the real cause of this attack [The May 7 attack by Paiute Indians on the station of J. O. Williams, in which seven men were killed and the house burned] is not definitely known, but two stories exist, both of which blame tho occupants of William’ station. One account charges that they seized several young Bannock squaws (allies of the Pah-Utes), leading to a punitive expedition by the red men, and another that the station keeper, J. O. Williams, himself stole a horse of a Pah-Ute leading to retribution on this score. Even before this attack it was reported that 30 horses belonging to the Pony Express had been stolen by the Indians (San Francisco dispatch, April 27, in New York Daily Tribune, May 8, 1860). William B. Russell replied that inasmuch as the Express still operated, there could be no foundation for the rumor.—Leavenworth Daily Times, May 10, 1860.”
