Gordon Webb was called up for military service as a Gunner in the Royal Artillery on the 9th September 1939. However in 1936 at Trinity College he had completed the requirements  necessary for the Officers Training Corps and was therefore eligible for consideration for a commission which he received [1][2].

March 1941, 2nd Lieutenant, No 4 Commando, Mentioned in Despatches for distinguished service during Operation Claymore.

Lieutenant Webb had been detailed to seize the Post Office and the only hotel in Svolvaer. This he did with incredible speed and thoroughness, thus stopping all communications to the mainland from the former, and taking a number of important enemy personnel prisoner in the latter. Had it not been for his quick action, news of the raid would undoubtedly have reached Narvik before it did, with consequences which might have been fatal to our Forces. [Recommended for the MC, received a MiD]. [3]

Captain Webb  was wounded by mortar fire on the beaches (Dieppe) during the initial landing. His right arm became useless but he insisted in going forward and led the whole of his force across country to the concentration area to the rear of the German battery. In the final assault Capt. Webb led a bayonet charge, using a revolver and grenades with his left hand. His troops accounted for many of the enemy including several officers [5].
