Spigot weapons, a unique British invention during World War II, were different from conventional mortars. Instead of a barrel, these weapons used a steel rod, or 'spigot', on which a bomb was placed before being fired. David Lister explores these weapons, revealing their effectiveness despite their controversial reputations.One such weapon, the PIAT (Projector, Infantry, Anti-Tank), became infamous during the Battle of Arnhem, where British paratroopers struggled with its performance compared to the German alternatives. Contrary to popular belief, the PIAT was a powerful anti-tank weapon, capable of taking down enemy tanks. Similarly, the Blacker Bombard, often mocked as a failure, was a formidable weapon used by the Home Guard, proving more effective than its reputation suggested.At sea, the Hedgehog anti-submarine weapon, another spigot design, was instrumental in sweeping U-boats from the Atlantic, though its potential was underused due to wartime secrecy. Lister examines these overlooked weapons and the genius of Latham Valentine Stewart Blacker, one of Britain’s key weapon inventors, who played a pivotal role in their development.Through these examples, the book uncovers the true power of spigot weapons and their vital contribution to the war effort.Previously published as Defeating the Panzer-Stuka Menace.
