It was impossible, under such circumstances, that hostilities should be long deferred. Commodore Young was the first to call on the convoy of a fleet of Dutch merchantmen to salute the British flag. They refused, and Young attacked them so smartly that in the end they complied. In a few days Van Tromp, who was a zealous partisan of Orange, and therefore of the house of Stuart, appeared in the Downs with two-and-forty sail. To Commodore Bourne, whom he found there, he disclaimed any hostile intentions, but pleaded the loss of several anchors and cables for putting in; but the next day, being the 19th of May, he encountered Blake off Dover, and that commander, though he had only twenty ships, demanded that Van Tromp should do homage to his flag. Van Tromp refused, and sailed right on till he came nearly opposite Blake, when the English admiral fired a gun three successive times at the Dutch admiral's flag. Van Tromp returned the compliment by firing a broadside into Blake's ship; and the two fleets were instantly engaged, and a desperate battle was fought from three in the afternoon till darkness separated them. The English had taken two ships, one of which, on account of the damage done it, was allowed to sink. There was much dispute between the two countries which was the aggressor; but it appears the most probable fact that Van Tromp sought an occasion to resist the demand of lowering the Dutch flag to the English one, and found an admiral as prepared to assert that superiority as he was to dispute it. The English Parliament immediately issued strict orders to all its commodores to pursue and destroy all the ships of the Dutch fleet that they could find on the seas; and in the space of a month they took or burnt seventy sail of merchantmen, besides several men-of-war. The Dutch protested that the battle had not been sought by them, and proposed inquiry, and the punishment of whichever of the commanders should be proved the aggressor; but the Parliament replied that it was satisfied that the States were bent on usurping the rights of England on the seas, and on destroying the fleets, which were the walls and bulwarks of the nation, and therefore that it was necessary to stand on the defensive. The States sent De Pauw to reiterate the assurances of their peaceful intentions, and to urge the court of inquiry; but the Parliament was now as high as the States had been before, and insisted on reparation and security. De Pauw demanded what these terms meant, and was answered, full compensation for all the expense that the Commonwealth had been put to by the hostile preparations of the States, and a confederation for the mutual protection of the two nations. De Pauw knew that the first of these terms would be declined, and took his leave. On the 19th of July the Parliament proclaimed war against the States.
