I came across your message about the 116 Ammunition Train while searching for more information about their service.
My grandfather was a Sgt. in Co. C, 116 Ammunition Train.
His personal notes records: Line of March:Brest; Langres; Anji; Montrichard; St. Cignon; La Celle, Burere; St. Amand; Paris
I also just found a reference to the 116th being reassigned in 1918 to the Remount Service:
THE CAVALRY JOURNAL Volume XXX, April 1921, Number 123 THE REMOUNT SERVICE IN THE A.E.F. By Maurice F. De Barneville (Former Lieutenant, Remount Service, A.E.F., American Embassy, Paris) (Excerpt) Until March 1918, only 12 troops of the 3rd Cavalry were performing remount work. Urgent requests sent to G.H.Q., by the Chief of Remount Service through the Chief Quartermaster caused the 2d and 15th Cavalry and the 116th Ammunition Train to be assigned to remount duty. But, even with this additional personnel (equivalent to about 33 Remount Squadrons), it was still difficult to handle the situation satisfactorily and a request for 43 remount squadrons was sent by Remount Headquarters to the Chief Quartermaster on May 11, 1918. On May 12, four remount squadrons arrived in France. On June 24, 1918, in response to a memorandum calling for an estimate of the remount personnel required, a report was sent to the Commanding General, S.O.S., asking for 89 Remount Squadrons in addition to the combatant troops then already assigned or for 122 remount squadrons in case this combatant personnel was relieved.
I would like to learn how long the 116th served with the Remount Service.
