Service number J.5766.
"This officer was captain of a VLR (Very Long Range) Liberator when he carried out three well-timed attacks against a strong resisting U-Boat with such accuracy that the enemy submarine was assessed as probably destroyed. Later in the same day in the vicinity of a convoy, he engaged another U-Boat with machine gun fire for over an hour, forcing it to submerge. Flight Lieutenant Aldwinckle, through a long career of many operational flying hours in the North Atlantic area, has met a continuously high standard as a captain and pilot. His initiative and devotion to duty have at all times been exemplary."
