Although Spain had been unable to drive the British from the coast or occupy any position, in the course of the diplomatic negotiations following the war, Britain found itself making concessions to Spain. In the 1786 Convention of London, Britain agreed to evacuate British settlers and their slaves from the Mosquito Coast to their as yet informal colony in what was to become British Honduras; later treaties recognized Britain's commercial, but never territorial rights in the region. Some of the settlers and their slaves remained after they swore loyalty to the King of Spain, especially in Bluefields.
