For conspicuous good service and devotion to duty on special operations. Sergeant Sherwood has carried out many patrols in which his work has been of a consistently high order. Also, when detached to work with the Eighth Army on the Cyrenaican coast, Sergeant Sherwood particularly distinguished himself when an attempt was made to capture a party of enemy on an island. Two folbots were used in this attempt, one being manned by Sergeant Sherwood and Captain Grant-Watson, Scots Guards. This boat capsized, and Captain Grant-Watson and Sergeant Sherwood attempted to swim to the mainland. The former, however, collapsed. A search for them was made by the first folbot, and Sergeant Sherwood was eventually found in the surf still supporting Capt Grant-Watson, though in great distress and difficulty himself. After artificial respiration had been applied Sgt Sherwood recovered, but Capt Grant-Wilson unfortunately died. It is clear that Sgt Sherwood made a most gallant and selfless attempt to save him.
