What the "Unit Citation and Campaign Participation Credit Register" tells me is the following (you may know much of this already but here goes...)
113th Cavalry Reconnaissance Squadron
Campaigns: Normandy (6/6/44 - 7/24/44) Northern France (7/25 - 9/14/44) Rhineland (9/15/44 - 3/21/45) Central Europe (3/22 - 5/11/45)
Distinguished Unit Citation: Issued for action (Troop C only) occurring during 4/4 - 4/7/45 (this would put him in Central Europe somewhere (Germany??))
War Department General Order: WD-GO-119-46 (this means that it was the 119th War Department General Order issued in 1946)
The squadron as a whole received a Foreign Unit Award called the "Belgian Fourragere" which was Belgiums highest national military award. This was for action from 9/5 - 9/8/44 and 9/11/44 and confirmed by Department of the Army General Order 43-50. They also received "occupation credit" in Germany from 5/2 - 9/19/45.
I hope of this will be of help to you. You can request the WDGO and the DAGO from:
Textual Reference Branch National Archives and Records Administration 8601 Adelphi Road College Park, MD 20740-6001
IF you get an archivist that has some good knowledge of WW2 records, they should be able to find these documents for you...it just may taken many weeks or months: be patient.
