After researching the acitivities of the 1st OR Cav., it appears they did not leave the state of Washington so I am assuming that the Harden Williams who died on the troop train was not Harden F. Williams of the 1st OR. Cav. I'm not sure, but I think the Harden Williams who was buried along side the train tracks near Omaha was a Confederate Soldier. What I have to go on is very vague. Clydene
