Operation Deadlight: The Day 116 Nazi U-Boats Were Sent to the Bottom of the Ocean

On May 8, 1945, the guns fell silent, but over 100 German U-boats were still prowling the oceans. In one of the most fascinating and overlooked chapters of World War II, the "Grey Wolves" of the Kriegsmarine were ordered to surface and surrender. But what actually happened to these formidable machines after the war ended?

In this episode of World War II Chronicles, we uncover the massive logistical challenge of the surrender at Loch Eriboll and Lisahally, the secret race between the US, UK, and Soviet Union to steal advanced Type XXI technology, and the explosive finale known as Operation Deadlight.

From the bottom of the Irish Sea to the museum exhibits in Chicago and Laboe, discover the final fate of Hitler’s submarine fleet.
