I just finished reading a history of the battle of the Hurtgen Forest (also covered in 'When Bugles fade', I believe) and wonder if this battle was based on that battle, if only loosly. That battle went on from SEP '44 to JAN '45, and caused thousands of casualties, as the Allies fought the well dug in German defenders in terrain that was in the defenders' favor. I haven't watched the movie in years, but it seems to fit the fighting and time frame.
shareI suppose is impossible to say what battle is.
The 95th infantry division was in Third Army (Patton), in the south front, next to Mediterranean forces advancing from Marseille (Dever's 6th army group).
Hurtgen forest is near Belgium. Far away from this division.
The 95th inf.div. fought many fortifications, the french-made Metz forts and then the Siegfred wall (West wall, for germans).
The concrete dragon teeth suggested the Siegfred Wall. But 95th assaulted both Metz and West Wall bunkers during late autumn and winter, slouching in mud, snow, and bad weather.
And this "battle" is set in summer - you may read in the trivia that some shots were done at night as was too hot to film in daylight and crews had heatstrokes.
Few U.S.Army unit fighted on Siegfried dragon teeth in warm weather. After the Normandy breakthrought, 4th Infantry div. pursued the fleeing germans up to West Wall in the end of september - bunkers were un-manned, but problems stopped the division (lack of fuel and exposed flanks).
So, I suppose it's a generic "somewhere and sometime during the war" battle.
