On 24 June 1944, Flight Lieutenant David Ernest Hornell of No. 162 Squadron RCAF carried out one of the most determined anti-submarine attacks of the war, pressing home his strike against a German U-boat in northern waters even after his aircraft had been badly hit. The action ended with the destruction of the submarine, the loss of Hornell’s aircraft, and a posthumous Victoria Cross that recognised extraordinary courage in one of the Battle of the Atlantic’s hardest arenas.
The patrol and the attack
Hornell was flying a Consolidated Canso, the Canadian-built Catalina used on long maritime patrols, when his crew sighted the surfaced U-boat U-1225. There was no element of surprise for long. The submarine’s anti-aircraft guns opened fire as Hornell turned in to attack, and the aircraft was struck repeatedly on the approach. Even so, he held his course. That decision mattered. Anti-submarine flying demanded steadiness under fire because the attacking aircraft had to remain committed long enough to deliver its depth charges accurately. To break away too soon was to give the U-boat a chance to escape and return to the shipping lanes. Hornell therefore continued the run despite the damage already suffered, and his attack sank the submarine. The cost was severe. His aircraft was left burning and badly damaged, but he still managed to bring it down at sea rather than lose everyone outright. In the cold North Atlantic conditions that followed, survival became a second battle.
Survival in the water
After the forced alighting, the crew faced heavy swell, cold water and the failure of much of their emergency equipment. Only one dinghy remained serviceable. The men had to cling on, rotate positions and endure prolonged exposure while awaiting rescue. Hornell, already injured and exhausted, used what strength he had left to help preserve order among the survivors and improve their chances of lasting until help arrived. Rescue eventually came after many hours in the water, but the ordeal proved too much for Hornell. He died soon after being picked up. His gallantry was not simply that he destroyed the enemy before thinking of himself; it was that he made the attack knowing the danger, then continued to fight for the survival of his crew after the aircraft had been lost.
Why the award mattered
The Victoria Cross awarded to Hornell recognised more than a single act of bravery. By the summer of 1944, Allied sea communications were central to the invasion of Europe, and Coastal Command’s anti-submarine work remained strategically vital. German U-boats still posed a serious threat to convoys, troop movements and the huge maritime effort supporting operations after D-Day. Hornell’s action lay at the intersection of personal gallantry and strategic necessity. A patrol aircraft over remote waters might seem far removed from the great land battles in France, yet the wider campaign depended on keeping the Atlantic routes open. In that sense, his attack represented the continuing air-sea struggle that underpinned Allied freedom of action.
A wider reflection on RAF and Commonwealth air power
Although Hornell served in the Royal Canadian Air Force, his mission formed part of the wider RAF Coastal Command system in which British and Commonwealth airmen fought a shared campaign across vast ocean spaces. His Victoria Cross remains one of the best-known examples of the courage demanded by maritime air operations: long hours of routine, sudden violence, and life-or-death consequences in some of the harshest conditions of the war. On that day, Hornell’s name entered RAF and Commonwealth history not because he survived the fight, but because he ensured the mission succeeded and gave others the chance to do so.
