Cromwell tanks of Guard's Armoured Division, British XXX Corps driving along 'Hell's Highway' toward Nijmegen, the Netherlands, 20 Sep 1944.

The ground on either side of the highway was in places too soft to support tactical vehicle movement and there were numerous dykes and drainage ditches. Dykes tended to be topped by trees or large bushes and roads and paths were lined with trees. In early autumn this meant that observation would be seriously restricted
