Although temporarily displaced by the Cromwellian protegés Robert Sedgwick and William Brayne, command of the forces ultimately devolved completely upon D'Oyley in September 1657.
Much of D'Oyley's time was taken up fighting the Maroons in the mountainous forests of the interior; they were runaway slaves who secured their freedom from their Spanish masters when the English took the island.
In about 1660, he persuaded the leader of one of the Maroon bands, Juan de Bolas, to switch sides and join the English.
[3][4] Besides this, D'Oyley was unable to persuade Juan de Serras, leader of the Karmahaly Maroons, to follow suit, and this group continued to fight against the English.
[6] In 1662, D'Oyley returned to England, where he established himself in St Martin-in-the-Fields, an Anglican parish in the City of Westminster, London.
