Lieut. (T./Capt.) Adrian James Boswell Tonks (Sea Patrol).
A brave and determined airman who has destroyed four enemy aeroplanes and driven down six out of control. In a recent engagement with twelve enemy scouts he destroyed one and drove off others who were attacking some pilots in his flight. In these combats he expended all his ammunition, but seeing three enemy machines attacking one of ours, he, with great gallantry, dived amongst them with a view to distracting their attention. In this he succeeded. A courageous and meritorious action.
