On 9/10 May 1918 at Ostend, Belgium, Lieutenant Drummond commanding HMML (Motor Launch) 254, volunteered for rescue work and was following HMS Vindictive to the harbour when a shell burst on board killing an officer and a deck hand and badly wounding the coxswain and Lieutenant Drummond. Notwithstanding his wounds, this officer brought M.L. 254 alongside Vindictive and then took off two officers and 38 men, some of whom were killed or wounded while embarking. He retained consciousness long enough to back his vessel away from the piers and towards the open sea before collapsing exhausted from his wounds.
