ADM 1 / 10830 – Awards to Members of the crew of HMS Cossack – Humane Society –At 1050 a British aircraft was shot down by enemy fighters and crashed near HMS Cossack. Sgt Johnstone was thrown out of the plane as sit struck the water. Cossack stopped about 100 yards short of the aircraft and Lt Gretton immediately jumped fully clothed into the water, which was thick with petrol, to assist the sergeant to safely reach the ship. This was regardless of the fact that Cossacks propellers were still in motion and that the ship may have to leave the scene if enemy aircraft arrived leaving him and the plane crew behind. Lt Gretton was awarded the Royal Humane Society Testimonial on Vellum.
