The principal was the transference of Elmina fort from the Dutch to the British, which took place on the 2nd of April 1872.
The Elmina were regarded by the Ashanti as their subjects, and the king of Ashanti held the Elmina "custom-note," - that is, he received from the Dutch an annual payment, in its origin a ground rent for the fort, but looked upon by the Dutch as a present for trade purposes.
Negotiations for their release were begun, but the Europeans were still prisoners when the sale of Elmina occurred.
They defeated the Fanti, stirred up disputes at Elmina, and encamped at Mampon near Cape Coast, to the great alarm of the inhabitants.
(1481-1495) the fortress of Sao Jorge da Mina, the modern Elmina, was founded for the protection of the Guinea trade in 1481-1482; Diogo Cam, or Cao, discovered the Congo in 1482 and reached Cape Cross in 1486; Bartholomeu Diaz doubled the Cape of Good Hope in 1488, thus proving that the Indian Ocean was accessible by sea.
