 Mansell was rewarded for his part in the victory and was named Vice @-@ Admiral of the Narrow Seas in commemoration of the name of the battle . Van Duyvenvoorde and Cant both received honorary golden chains from the States of Holland . As for Spinola , he managed to save half of the galleys , as the two which had reached Nieuwpoort were soon able to join San Luis in Dunkirk . From there , the three ships sailed unmolested to Sluis , where Spinola with his five galleys still possessed a threat to the English and Dutch shipping . Both the English and the Dutch were gradually able to gain supremacy in the seas not just in and around the English Channel but in all the European waters . As a result , Spinola would be defeated again and mortally wounded at the Battle of Sluys by the blockading Dutch forces in an attempt to escape . Spinola 's death and the subsequent surrender of Sluis to the Dutch in 1604 ended his and Philip III 's dreams , and English fears , of a galley @-@ borne invasion of England from Flanders .
