British settlements on the "Spanish Continent" were…
July 1786 CE
British settlers in the area have resisted implementation of the 1783 agreement, observing (as they had after the 1763 treaty) that the Spanish had never actually controlled the area, and that it therefore does not belong to the "Spanish Continent".
After both sides increase military activities in the area of the Black River Settlement, where most of the British settlers live, it is decided to engage in further negotiations to resolve the issue.
In the agreement signed July 14, 1786, Britain agrees to evacuate all British settlements from the Mosquito Coast.
In exchange, Spain agrees to expand the territory available to British loggers on the Yucatan Peninsula, and allows them to cut mahogany and other hardwoods that are increasing in value.
Over the opposition of the Mosquito Coast settlers, the agreement is implemented, and the British evacuate more than two thousand people.
Most of them go to Belize, but others are relocated to Jamaica, Grand Cayman, or Roatán.
Control of Black River is formally turned over to the Spanish on August 29, 1787, by the grandson of its founder, William Pitt.
