The manning of the fleet caused nearly as much discussion as did the victualling, and about this period Rupert and James of York were by no means of one mind concerning it. Rupert dismissed James's men as cowards, and James rejected Rupert's "stout men" as drunkards. "If they will turn out every man that will be drunk, they must turn out all the commanders in the fleet," cried the exasperated Prince. "What is the matter if a man be drunk, so, when he comes to fight, he do his work?"[[59]] But the dispute ran high; James declared he "knew not how" Colonel Legge's son had been made a captain after a single voyage, and, though he liked Colonel Legge well, he insisted that the boy must serve a longer apprenticeship. "I will ask the King to let me be that I am—Admiral!" he declared wrathfully, when Rupert combated his decisions.[[60]] The King listened to all these disputes with his usual lazy good nature. "If you intend to man the fleet without being cheated by the captains and pursers, you may go to bed and never have it manned at all," he said.[[61]] But James had his way in so far that Sir William Penn was appointed to command the summer fleet, in spite of Rupert's aversion to him. "I do pity Sir William Penn," quoth Pepys, naively.[[62]]

Owing to the representations of Rupert "and other mad, silly people," as Pepys phrased it,[[63]] no large fleet was fitted out in 1668; and, so far as the navy was concerned, no events occurred until 1672, when the second Dutch war broke out.

This war was as unpopular as the first had been popular. In the interval between them Charles II had made the secret Treaty of Dover with Louis XIV, and he now entered into this war solely to assist Louis' ambition. Therefore instead of the English opposing the Dutch and French, as formerly, the French and English were now allied against the Dutch. Rupert and Ormonde vigorously opposed the declaration of war, and perhaps it was on account of his dislike to the whole business that the Prince remained at home, while the Duke of York took command of the fleet. Nevertheless Rupert was put in command of all naval affairs on shore, and he resolved that the fleet should not suffer as it had before done, for the want of all necessary supplies.

His first act in his new capacity was to summon Pepys, and his colleagues to give an exact list of the fleet, the station and condition of each ship, and an account, "particular, not general," of all their stores, great and small.[[64]] He diligently superintended the fortification of the coast, inspected the regiments there stationed, and kept a watchful eye on the necessities of the fleet. But, in spite of this efficient assistance on shore, James accomplished nothing of moment, and the battle of Southwold Bay, fought May 28, left the honours to the Dutch, though both sides claimed the victory.

Before the next campaign, the Test Act had been passed, by which Roman Catholics were prevented from holding any office under the Crown. This forced the Duke of York to resign his command of the fleet, and Rupert was appointed to take his place.

Rupert's position was a difficult one. He detested the secret policy of Charles, and consequently the French, who were his allies. With the Cabal, as the home Ministry was then called, he was also at enmity. The Ministers, therefore, in order to make him as inefficient as possible, manned the fleet with adherents of the Duke of York, who were told—though falsely—that detracting from the Prince would please the Duke. Therefore "they crossed him in all that they could, and complained of all that he did." In short, Rupert had to contend with intrigues at home, limitation of his proper powers, want of men, ammunition and provisions, the deceit of the Naval Commissioners, insubordination among his officers, and defection of his allies.[[65]]

As his second in command, he begged to have Holmes, with whom his connection had been so long and intimate. Thanks to the favour of both Rupert and the Duke of York, Holmes had risen high in the navy, and was now an Admiral, and Governor of Sandown Castle, in the Isle of Wight. His promotion seems to have excited some jealousy, and Marvell described him bitterly, as "First an Irish livery boy, then a highwayman, (a pirate would be nearer the mark,) now Bashaw of the Isle of Wight, the cursed beginner of the two Dutch wars."[[66]] The last sentence alludes to Holmes's exploits in Africa in 1664, and his attack on the Smyrna fleet in 1672, which were the immediate causes of the wars of 1665 and 1672 respectively. But in both cases Holmes only obeyed orders for which he was not responsible. Pepys hinted darkly, concerning him, that "a cat will be a cat still,"[[67]] but then Pepys had private reasons for disliking him. He was a good soldier, and an experienced sailor, and the Cabal Ministry had no better reason for refusing to let him go with Rupert than the fact that he was the Prince's friend. Instead of Holmes they forced Rupert to take Sir Edward Spragge, with whom he was not, then, on good terms.[[68]]

The long delay in setting out the fleet tempted the Dutch to repeat their descent upon the Medway, and this they would undoubtedly have done, but for the personal energy of the Prince. Collecting together a few ships, he "made a demonstration", and sailed through the Channel, to the great surprise of the Dutch, who immediately retired.[[69]]

By May 20th the English fleet was ready to sail, and it was at once joined by the French, under Admiral D'Estrées. About a week later they fell in with the Dutch off Schoneveldt. Rupert sent a few vessels forward to draw out the enemy from their harbour, but De Ruyter came upon them so unexpectedly that they crowded back in confusion, each falling to the squadron nearest to her. The place was narrow, the wind for the Dutch, and some of the officers advised retreat. "But," said the English proudly," our Admiral never knew what it was to go back,"[[70]] and Rupert insisted on fighting then and there. When De Ruyter attacked, the line of the allies was not ready, and the result was an indecisive battle, attended with great loss of life.[[71]] In his official report, the Prince acknowledged that all had done their best:—"All the officers and seamen generally behaved themselves very well, of which I shall send the particulars when I am better informed; in my squadron, more especially Captain Legge, Sir John Holmes, Captain Welwang, Sir Roger Strickland and Sir William Reeves. Sir Edward Spragge also, on his side, maintained the fight with so much courage and resolution, and their whole body gave way to such a degree, that, had it not been for fear of the shoals, we had driven them into their harbours. The case being thus, I judged it fit to stand off a little, and anchor where now I ride. I hope his Majesty will be satisfied, that, considering the place we engaged in, and the shoals, there was as much done as could be expected; and thus I leave it to His Majesty's favourable construction, to whom I wish many happy years to come, this being his birthday."[[72]]
