For 70 years, a significant chunk of taxpayers' money had been gathering silt. Five hundred miles from the nearest land and three
miles beneath the surface of the Atlantic, £50 million worth of British silver has lain on the seabed. Now, thanks to the deepest
salvage operation in history, H.M. Treasury had got most of its silver back.
On November 6, 1942, the steamer City of Cairo is on a desperate mission. From across the empire, Whitehall had called in
Britain's remaining riches to fund a war that still felt like a threat to its very existence.
Steaming across the Atlantic, midway through a perilous journey that began in India and took it around the Cape of Good Hope,
the merchant ship was carrying 100 tonnes of silver rupees to pay for British food and arms. They are not to reach their
destination.
Spotted by a U-boat and torpedoed, the City of Cairo is fatally holed. The U-boat captain surfaced amid the lifeboats and pointed
them towards the nearest land: Saint Helena, 500 miles away, or, as far again but harder to miss, Namibia. "Goodnight," he said,
"and sorry for sinking you."
As U-68 left to continue hunting, and the lifeboats embarked on a weeks-long journey led by Captain William Rogerson that
would became one of the epic tales of maritime survival, a cargo that would be worth £50 million today hit the Atlantic floor.
It has required some extraordinary advances in undersea exploration, but a salvage company led by John Kingsford, a British
deep sea diver, has retrieved the vast majority of it - from a depth a mile lower than the Titanic's final resting place.
After signing a contract with the British government, his company has been allowed to keep an undisclosed proportion of the
treasure.
