Allied intelligence thought that five or six German divisions were in the area, although U.S. 5th Army intelligence severely underestimated the German 10th Army's fighting capacity at the time, believing many of their units would be worn out after the defensive battles fought since September.
De allierede efterretningstjenester mente, at der var fem eller seks tyske divisioner i området, men den amerikanske 5. armés efterretningsvæsen undervurderede stærkt den 10. tyske armés aktuelle kampkraft, idet den mente, at mange af enhederne var udkørte efter at have været involveret i defensive slag siden september.
