U-Boats Expected Safe Harbor in France — RAF Tallboy Bombs Collapsed Concrete Pens

Discover how RAF Tallboy bombs shattered Germany's "impregnable" U-boat fortresses in France. When Germany captured France in 1940, the Atlantic coast became a submarine paradise—until Barnes Wallis designed a revolutionary 12,000-pound weapon that defied physics itself. This documentary reveals the incredible engineering battle between Organisation Todt's massive concrete bunkers at Lorient, St. Nazaire, and Brest versus RAF 617 Squadron's precision Tallboy bombs. Watch how conventional bombing failed spectacularly for three years before Barnes Wallis—creator of the bouncing bomb—calculated a devastating solution: deep-penetration weapons that punched through seven metres of reinforced concrete and triggered earthquake effects from inside the structure. From Admiral Dönitz's strategic triumph gaining French Atlantic bases to Wing Commander Leonard Cheshire's surgical strikes that collapsed "bombproof" pens, experience the complete story of how British innovation destroyed Germany's most valuable naval infrastructure and crippled the U-boat campaign's final year. Featuring authentic dates, technical specifications, combat statistics, and the remarkable physics that transformed aerial warfare forever. #wwii #battleofbritain #britishsoldier #britishhistory SOURCES Primary Archives & Official Records: The National Archives, Kew – AIR 14/3410: Bomber Command Operations Records, U-boat Base Attacks 1942-1944 The National Archives – AIR 27/2128: 617 Squadron Operations Record Book 1943-1945 Imperial War Museum – Documents.12891: Barnes Wallis Papers on Tallboy Development RAF Museum, Hendon – AC/72/12: Tallboy Bomb Technical Specifications and Trial Results German Military Archives: 5.
