“[Due to] concern over riots and strong Southern sympathies in St. Joseph as well as with the new ownership and management, Atchison became the eastern terminus of the Pony Express. It was about fifteen miles further west, and by then, it was also served by the railroad and the telegraph.”
[N.B. re: ownership and management: “On April 26 [1861], Russell was asked to resign [as president of California Overland Central and Pike’s Peak], and Bela Hughes became president of the C.O.C & P.P. Hughes was Benjamin Holladay’s cousin.”]
