"Treasure is Trouble"

£2.6 billion worth. From the Telegraph:

In a project shrouded in secrecy, work is due to start on recovering the cargo, which was being transported to the United States to help pay for the Allied effort in the Second World War...

In order to protect its find until the cargo is brought to the surface, the company that located the wreck has not released the name of the vessel or its exact location, but has given the ship the code name "Blue Baron".

It says the merchant ship, which had a predominantly British crew, had left a European port, laden with goods for the US Treasury under the Lend-Lease scheme, whereby the American government gave material support to the Allied war effort in exchange for payments.

The Blue Baron first sailed to a port in South America, where it unloaded some general cargo, before continuing north in a convoy, heading for New York.

However, the company claim it was intercepted by German U-boat U87 and sent to the bottom by two torpedoes in June 1942, with the loss of three crew members. Their nationalities are not known.

Sub Sea Research, a US-based marine research and recovery firm, claims it has now located the wreck under 800ft of water about 40 miles off Guyana.

This could be worth as much as £2.6 billion, as the cargo included as much as ten tons of gold bullion, 70 tons of platinum, diamonds, and even tin and copper. Interesting that this was the expected payment for part of the lend-lease program. It is striking as well that there is very little mention of any archaeological study of the wreck, despite the very recent history, and mystery surrounding the sinking of vessel.
