I had a wide interest on this battle and read almost everything that was available to me, whether it were printed or internet sources or articles.
And I still have it. This was with no doubt one of the hardest, bloodiest and most miserable battles not only in WW2, but in the whole history of warfare! The stiff resistance, the never-ending shelling, mines and fire from pillboxes and fortified villages was one of the worst the American troops on ETO had to get through. The movie
When Trumpets Fade does an excellent job in describing a small episode of it.
It may be of interest, that in the Czech version of the movie I saw they have incorrectly translated Hurtgen as Ardennes. This only adds to the fact of how largely this battle is forgotten, overshadowed by other campaigns.
Troops of both sides fought for months, in miserable conditions, in many cases with minimum food or ammo. While other battles were fought in a relatively short time, this slaughter went on for six months, gentleman! It's not a coincidence, that one German commander compared it to the hard battles he went through on the Eastern front.
I have also created a group dedicated to this tragic battle, join it if you want!
