Ah, and that was the armoured attack through forests that were thought to be impassable to tanks but which were in fact NOT impassable....
Something tells me that Churchill's would not have fared too well on the Kall Trail.
Having walked the ground at both locations, possibly. OTOH having gone through some of the unit War Diaries, the M4 might not have fared too well in the Reichswald either.
Having gone through most accounts of the November Hurtgen battle, including the 707th TB records, it seems unlikely. The main problem was the infamous "boulder" on the trail constricting the width at one curve. In backing and filling to get around a couple of tanks lost tracks, and IIRC one slid down the slope. They tried to blast it away, but didn't want to lose what trail they had. I suspect the extra two feet of width in the Churchill would have put paid to that.
OTOH, I readily agree the Sherman probably wouldn't have done too well in the Reichswald, where the Churchill was in its element.
TBH I was pretty surprised they managed to get tanks down the Kall Trail, and the track marks were still clear when I was there. I suspect the Churchill's extra weight wouldn't have helped either, especially with regard to that dinky bridge over the river...
TBH in turn, I have never been able to figure out why anyone expected the so-called "plan", such as it was, foisted upon Cota by Gerow, Hodges, and Bradley, to succeed. Three regiments, attacking in three different directions, with three dispersed objectives. Hubris or stupidity? I think a bit of both and mostly generated from Bradley.
