How a 5-Foot British Plate Made 14 U-Boats Sink Themselves—Their Own Torpedoes Turned Around

The Germans spent years building a torpedo so smart it could hunt by sound alone. The British defeated it in 48 hours — with two steel bars. In 1943, the Kriegsmarine unleashed the Zaunkönig — an acoustic torpedo designed to home in on the propeller noise of Allied destroyers. It was supposed to win back the Battle of the Atlantic. Instead, a crude British noisemaker called the Foxer lured these sophisticated weapons away from their targets, sent them circling in the dark, and in at least 14 confirmed cases drove them straight back toward the U-boats that fired them. This is the story of the cheapest, simplest, and most brutally effective counter-weapon of World War Two. #WW2 #BattleOfTheAtlantic #NavalHistory #Uboats #WorldWarTwo #MilitaryHistory #RoyalNavy #Kriegsmarine #WW2History #SubmarineWarfare #HistoryDocumentary #WW2Documentary
