Operation Deadlight – The Royal Navy Scuttled 116 Captured U-Boats After WWII
Operation Deadlight was a post-World War II undertaking by the Allies, primarily led by the British Royal Navy, to scuttle over 100 captured German U-boats in the North Atlantic.
Initiated in late 1945 and extending into 1946, the operation involved towing the submarines to a designated area northwest of Ireland, where they were sunk.
