The "Suicidal" Weapon of World War Two — And Why It Won 6 Victoria Crosses

The Piat was the weapon every British soldier hated and every German tank crew learned to fear. Its effective range was fifty yards. Its mainspring required two hundred pounds of compression to cock manually. One round in four failed to detonate on impact. And if you missed, the tank was still coming while you wrestled the spring back into position with your feet. Every man who carried it said the same thing. It was rubbish. It was also rubbish that stopped a German tank from reaching the beaches of Normandy on D-Day. Rubbish that outperformed Allied aircraft in the tank-killing role during the Normandy campaign. Rubbish that earned six Victoria Crosses — more than any other single British infantry weapon of the Second World War. This is the full story of the Piat — how a secret Churchill-backed weapons unit designed it outside normal military bureaucracy in nineteen forty-two, why its complete absence of backblast gave it a decisive advantage over the American Bazooka and the German Panzerschreck in urban combat, how Canadian infantry used it to blow holes through building walls at Ortona, and what Major Robert Cain did with one at Arnhem over nine days — blinded on the first shot, eardrums burst by the second day, still fighting when everyone else had stopped. If you care about the weapons that won battles by being used in conditions no designer anticipated, and the men who carried them past the point where the specifications ran out — this is the channel for you.
