My late father-in-law served in a 105mm field artillery battalion in the 78th “Lightning” Division during WWII. The division was on the very north edge of the Bulge.

As a side note, in the original “Battlestar Galactica” TV series, the crew of one of the ships wore the 78th’ patch on their uniforms.
Stanton’s WWII Army Order of Battle shows no 1104 Engineer Combat Battalion existed.
