After pursuing the remnant of the Spanish fleet to Dunkirk, the Dutch Admiral returned triumphant to the Downs, and saluted the English squadron by striking his flag and firing nineteen guns,--“as a token,” says an ironical observer, “that his Majesty was Sovereign of these his seas!”[603] Tromp indeed, in those years, was most punctiliously respectful to this symbol of the king’s sovereignty. Even during the height of the battle, when he was violating not merely the sovereignty claimed by Charles but the well-understood Law of Nations, he kept his flag down until he was a good way off from the Downs,--a circumstance which Pennington reported with satisfaction. Had the Dutch Admiral shown the same willingness to strike to the flag of the Commonwealth when he encountered Blake thirteen years later, the war that followed might, perhaps, have been averted, or at least postponed. Charles was very naturally highly incensed at this open flouting of his authority. It was an ugly blot on the lustre of his ancient prerogative, and a painful proof of the contempt in which his much-vaunted naval power was held by the Dutch Republic, and--what perhaps he felt quite as much at the time--it robbed him of all chance of blackmailing Spain. When that Power was asked to pay the great sum above mentioned, the Cardinal Infant put the proposal aside, considering that it was the king’s own interest to protect the Spanish fleet; and when Tromp’s precipitation broke in on the negotiations, it was decided to withhold any payment at all until it was seen how Charles would resent the injury done to Spain.[604] At first he resolved to punish the affront. Pennington was ordered to cause the Dutch fleet, which had returned to the Downs, and was suspected of meditating further “insolency” by falling upon the stranded galleons, to immediately quit the road. The king, he was told, had made up his mind not to allow them the liberty of his ports or roads “until he shall have received satisfaction for the insolency already committed.” If they refused to leave, Pennington, immediately the other ten ships had reinforced him, was to drive them out with all his power and strength, or answer the contrary at his uttermost peril. Before these orders could be executed, Tromp voluntarily departed.[605] Copies of the letter to Pennington were sent to Brussels and Madrid to show the Spaniards that the king was full of resolution. They were told he was very sensible of the affront and insolence of the Hollanders, and “would make such demonstration of it, and demand and expect such reparation as in honour he is obliged.” But he was quite unable to carry out his good intention. It was in vain that he was urged from Madrid to take strong measures against the Dutch; to seize their property; even to invade Normandy as a punishment to their ally.[606] He had no fleet and no money to enable him to cope with the Dutch Republic, even if the condition of home affairs had permitted the attempt.
