HMAS CANBERRA intercepted the German raider supply ship COBURG and a captured tanker, KETTY BROVIG east of Italian Somaliland. These two ships were support vessels for three German raiders then active in the Indian Ocean. CANBERRA opened fire on COBURG, and her crew then scuttled the ship, then she launched her Seagull aircraft which intercepted the KETTY BROVIG and dropped bombs close by her to make her stop, but the ships crew began to scuttle the ship. The Seagull aircraft landed close to the KETTY BROVIG, and her observer, (LEUT C.V.S. Malleson, RN), swam across to the ship to try and prevent the ship’s crew from scuttling her, but he was too late. He retrieved some of the ships papers before being taken off the ship. Despite attempts to salvage the vessels, they were both at the point of sinking, and were dispatched by gunfire from CANBERRA.
