Mere words can convey only a very limited understanding of a very special man: however, they will hopefully prompt further research on the part of those who appreciate just how fundamental to our society are the inseparable virtues of service to, and sacrifice on behalf of, one’s fellow human beings.
"At the end of the quay (facing the U-Boat Pens), we came to the Place de la Vieille Ville, an open, broad area beyond which lay.....Bridge 'D', a girder bridge about 70 yards off. The bridge and the square were under heavy enemy fire, including that from an 88mm gun. We all went for it like long-dogs. I recall (Captain) Donald Roy, sweeping along the middle of the road, erect in his kilt, the cheerful Colonel Charles Newman and the confidence-inspiring Major Bill Copland who was a rock to us all.... A hail of enemy gunfire erupted as we crossed the bridge, projectiles slamming into its girders, bullets whining and ricocheting off them and from the cobbles. There was a roar of gunfire of varying calibres and the percussion of 'potato-masher' grenades as we neared the far end. One of the latter burst at my feet and the explosion, combined with my own forward velocity, lifted me clean off the ground, wounding me in the left leg and shoulder. I remember landing on the back of the sturdy (Captain) Stanley Day, No. 2 Commando's Adjutant. I could feel my left battledress trouser leg wet with blood, but beyond a sense of numbness my leg still worked and I quickly forgot about it."
