The Dutch government this week got back tens of thousands of dollars worth of silver bullion that was lost in a shipwreck in 1739. The Rooswijk, a ship owned by the Dutch East India Company, had just embarked on a voyage to the East Indies, laden with silver to be made into coins, when it sank in the English Channel. There were no survivors among the 250 crew and passengers. A British diver found the wreck last year, with chests of silver bars still intact. But the discovery was kept secret to give archaeologists time to study the wreckage and recover the treasure.
