De Ruyter's activities in the American waters had less satisfactory results than those off West Africa. Arriving off Barbados in the Caribbean at the end of April 1665 aboard his flagship "Spiegel" ("Mirror"), he led his fleet of thirteen vessels into Carlisle Bay, exchanging fire with the English batteries and destroying many of the vessels anchored there. Unable to silence the English guns and having sustained significant casualties and considerable damage to his vessels, he retired to French Martinique for repairs.
