German Submariners Studied American Convoy Routes - Then A New Weapon Found Them First.

Описание: In October 1940, German U-boats surrounded Allied convoys in the North Atlantic and tore them apart with devastating wolf pack tactics. Legendary commanders like Otto Kretschmer, Gunther Prien, and Joachim Schepke became heroes in Germany, sinking hundreds of thousands of tons of shipping while Allied escorts struggled to fight back. When Germany declared war on America, U-boat commanders like Reinhard Hardegen sailed to the American coast armed only with tourist guidebooks, launching Operation Drumbeat and beginning the Second Happy Time that would sink over six hundred ships in just eight months. But thousands of miles away, British scientists were developing secret weapons that would change everything. The cavity magnetron, the Leigh Light, the Hedgehog mortar, and the acoustic homing torpedo would combine with Ultra intelligence and new escort carriers to create a technological revolution the German submarine force never saw coming. This documentary tells the complete story of the Battle of the Atlantic, from the wolf pack triumphs of 1940 to the catastrophic Black May of 1943 when forty two U-boats were lost in a single month. Featuring verified accounts from commanders on both sides, detailed explanations of the technologies that turned the tide, and the human stories of the young submariners who faced a seventy percent casualty rate, this is the dramatic history of how the longest campaign of the Second World War was won and lost beneath the waves.
