from the East India Company, which had leased it as a calling-place on the sea-route round the Cape. This was Cormantin, a few miles east of the Dutch station of Cape Coast Castle, now in Ghana. The 1663 charter prohibits others to trade in "redwood, elephants' teeth, negroes, slaves, hides, wax, guinea grains, or other commodities of those countries". In 1663, as a prelude to the Dutch war, Captain Holmes's expedition captured or destroyed all the Dutch settlements on the coast, and in 1664, Fort James was founded on an island about twenty miles up the Gambia river, as a new centre for English trade and power. This, however, was only the beginning of a series of captures and recaptures. In the same year, de Ruyter won back all the Dutch forts except Cape Coast Castle and also took Cormantin. In 1667, the Treaty of Breda confirmed Cape Coast Castle to the English. Forts served as staging and trading stations, and the company was responsible for seizing any English ships that attempted to operate in violation of its monopoly (known as interlopers). In the "prize court", the King received half of the proceeds and the Company half from the seizure of these interlopers. The Company fell heavily into debt in 1667, during the Second Anglo-Dutch War. For several years after that, the Company maintained some desultory trade, including licensing single-trip private traders, but its biggest effort was the creation in 1668 of the Gambia Adventurers. This new company was separately subscribed and granted a ten-year licence for African trade north of the Bight of Benin with effect from 1 January 1669. At the end of 1678, the licence to the Gambia Adventurers expired and its Gambian trade was merged into the company. The African Company was ruined by its losses and surrendered its charter in 1672, to be followed by the still more ambitious Royal African Company of England. Its new charter was broader than the old one and included the right to set up forts and factories, maintain troops, and exercise martial law in West Africa, in pursuit of trade in gold, silver and African slaves. Until 1687, the company was very prosperous. It set up six forts on the Gold Coast, and another post at Ouidah, farther east on the Slave Coast, which became its principal centre for trade. Cape Coast Castle was strengthened and rose to be
