An attack made by his fleet on Barbadoes proved unsuccessful, but the damage done to English trade was considerable. Then De Ruyter stretched along the coast of North America as far as Newfoundland. He failed to retake New Amsterdam, which, under the name of New York, remained in our hands at the close of the war. From Newfoundland he returned home. This counter-stroke provoked a furious outcry of anger in England, for it is perhaps more the custom of the English than any other nation to be seized with unaffected moral indignation when another does unto them the disagreeable thing which they have just been doing to someone else. Letters of marque and reprisal were now issued on both sides, and a privateering war of plunder preceded regular hostilities. The Dutch oligarchy would still have made peace if they could, but the English Court had at last found its pretext, and was resolved to force on the quarrel. The terms upon which it insisted were such as a people far less courageous and less powerful than the Dutch could not possibly have accepted. The formal declaration of war was delayed until March 1665. No great change had taken place in the relative strength of the two navies since the conclusion of the first Dutch war. The English still had the superiority which they derived from unity of command and the greater strength of their ships. The Loevenstein Party had done nothing to remove the fatal defects of organisation in the fleets of the United Provinces. Indeed it could do nothing, since the only way in which unity of command could be given to the different squadrons of the Provinces was by again naming a Stadtholder, and allowing the office to carry with it the post of Admiral-General. But to ask the Loevenstein Party to do this was to ask them to commit suicide. So we find the same divisions of authority in the Dutch fleet in this as in the former war. The commercial government of the Republic had done nothing, and perhaps from its character could do nothing, to establish a higher standard of military spirit among its officers. On the side of England the monarchy was still profiting by the work of the Council of State and Oliver Cromwell. The corruption which in the later years of King Charles's reign invaded every detail of the administration of the navy had not yet got the upper hand. Although the practice of giving the command of ships to young gentlemen who had absolutely no qualification beyond their interest at Court was already followed, still the bulk of the captains and all the flag-officers, with few exceptions, were the veterans of the first Dutch war. These men were already accustomed to act together; they had fought side by side in many battles, and had cruised in company for months. They had the tradition of the last war fresh in their minds. To this must be attributed the general good discipline and efficiency displayed in the coming struggle.
