On the night of 24/25 October 1944 the leading infantry advancing into South Beveland were stopped by a roadblock of mines and wire obstacles covered by heavy fire from a dyke commanding the area Map Reference 537203. An infantry company attack followed by an artillery concentration, followed by a second company attack failed to secure the roadblock. There was no possible diversion due to flooding. At 0530 hours, 25 October 1944, a small party of Sappers was chosen to attempt to clear the roadblock which was threatening the advance of the division. Lance-Sergeant Jessome specially requested to be included in this task. He personally removed most of the wire obstacles which were being swept by vicious machine gunfire. He then proceeded 100 yards beyond the roadblock to ensure that there were no more mines in the road.

This man's leadership and complete contempt of danger provided a steadying example for the entire Sapper party and the obstructions were completely removed in quick time. The rapid advance of the division was thus maintained
