Treasure hunters will shortly set sail to search for £300bn worth of British gold after identifying 700 war wrecks.
Extensive research over many years has identified the locations of hundreds of the 7,500 merchant ships lost in both world
wars.
Gold bullion was shipped to the US and other locations for safekeeping and to pay for munitions and goods. Whilst there is much information on which ships carried silver, the gold shipments were classified secret, meaning data on possible locations were scarce.
