 Among the German casualties were the operations officers of two of the three XC "Korps" divisions.Of the units of the outsized (six divisions) XV Corps, only a regiment of the 45th Infantry Division (Maj. Gen. Robert T. Frederick) faced a water obstacle at the start.That regiment had to cross the Blies River at a site upstream from where the Blies turns northeast to meander up the Kaiserslautern corridor.
