The Market Garden operation was a mistake in all respects . It used a single road that was used pre war by the Dutch army to demonstrate to it's officer cadets the stupidity of such an exercise . It was a road with soft ground unsuitable for heavy vehicles on both sides .
As I mentioned in another M/G thread my father had a NATO meeting in this area. His NATO guide was in the Dutch Underground during this period. He drove my father up and down XXX Corps route (much of which hasn't changed since 1944), neither of them could understand just how XXX Corps was supposed to get up this easily defended road in 2-3 days. You had to know the Germans would throw every reinforcement available in to stop them...
