Jamestown was founded in 1659 by the
East India Company and is named after James, Duke of York, the future King
James II of England. A fort, originally named the Castle of St John, was quickly built and, with the restoration of the monarchy in 1660, the fort was renamed James Fort, the town Jamestown and the valley James Valley. In January 1673 the
Dutch East India Company briefly seized control of the island until the English East India Company recaptured it in May. Since then the town has been continuously inhabited under English and then British rule. After his defeat in the
Battle of Waterloo in June 1815 and the subsequent occupation of Paris, the
Emperor of the French,
Napoleon, surrendered to the British and was exiled to St Helena. He arrived on 21 October aboard the 74-gun ship and resided at the
Briars in Jamestown for several months until he was transferred to
Longwood House in a more remote part of the island in December. Jamestown was chosen to host a vice admiralty court and a naval base for British efforts to stop the slave traffic between Africa and the Americas. Captured
slave ships were often brought to Jamestown to be sold and their cargos were off-loaded in Rupert's Valley. By the time that the naval station was closed in the 1870s, an estimated 25,000 slaves had been rescued, although about 5,000 died shortly after arrival and were buried in Rupert's Valley. Their graves, long lost, were rediscovered in 2006 in conjunction with preliminary digging for the airport. A team of
archaeologists arrived in mid-2008 to excavate the graves. Some of the finds from the excavations are on exhibit at the
International Slavery Museum in
Liverpool, England. The island was too isolated to play any role in the
First World War and only played a minimal one during the Second World War. The
oil tanker RFA Darkdale was sunk by the in James Bay on 22 October 1941 with only nine of the 50-man crew surviving. She had been sent to St Helena a few months earlier to refuel ships operating in the South Atlantic. The wreck continued to leak small amounts of oil until June 2015 when the
Ministry of Defence sent a team of divers to pump out all the remaining oil. ==Geography and description==
