Hi! Fred Cardwell died during an air raid (or patrol flight) to Kronstadt on 25 October 1919. The weather was bad. He was flying a seaplane when the Soviet anti-aircraft got him and his plane crashed to the sea. The Royal Navy sent a CMB to rescue him but it came too late. The Reds had towed his plane off. Fred Cardwell is most probably buried on Kronstadt (if not there then in St. Petersburg). The sea plane base was situated on the North side of the Sudensaari island very close to the town on Koivisto (Björkö) and it was a part of the RAF squadron attached to HMS Vindictive (one of the first air craft carriers).
