Great preparations were made in England to recover this disgrace; eighty sail put to sea under Blake, Dean, and Monk, so celebrated subsequently as the restorer of the monarchy. Tromp and De Ruyter, with seventy-six vessels, were descried on the 18th of February, escorting three hundred merchantmen up Channel. Three days of desperate fighting ended in the defeat of the Dutch, who lost ten ships of war and twenty-four merchant vessels. Several of the English ships were disabled, one sunk; and the carnage on both sides was nearly equal. Tromp acquired prodigious honor by this battle; having succeeded, though defeated, in saving, as has been seen, almost the whole of his immense convoy. On the 12th of June and the day following two other actions were fought: in the first of which the English admiral Dean was killed; in the second, Monk, Pen, and Lawson amply revenged his death by forcing the Dutch to regain their harbors with great loss.

The 21st of July was the last of these bloody and obstinate conflicts for superiority. Tromp issued out once more, determined to conquer or die. He met the enemy off Scheveling, commanded by Monk. Both fleets rushed to the combat. The heroic Dutchman, animating his sailors with his sword drawn, was shot through the heart with a musket-ball. This event, and this alone, won the battle, which was the most decisive of the whole war. The enemy captured or sunk nearly thirty ships. The body of Tromp was carried with great solemnity to the church of Delft, where a magnificent mausoleum was erected over the remains of this eminently brave and distinguished man.

This memorable defeat, and the death of this great naval hero, added to the injury done to their trade, induced the states-general to seek terms from their too powerful enemy. The want of peace was felt throughout the whole country. Cromwell was not averse to grant it; but he insisted on conditions every way disadvantageous and humiliating. He had revived his chimerical scheme of a total conjunction of government, privileges, and interests between the two republics. This was firmly rejected by John de Witt, now grand pensionary of Holland, and by the States under his influence. But the Dutch consented to a defensive league; to punish the survivors of those concerned in the massacre of Amboyna; to pay nine thousand pounds of indemnity for vessels seized in the Sound, five thousand pounds for the affair of Amboyna, and eighty-five thousand pounds to the English East India Company, to cede to them the island of Polerone in the East; to yield the honor of the national flag to the English; and, finally, that neither the young Prince of Orange nor any of his family should ever be invested with the dignity of stadtholder. These two latter conditions were certainly degrading to Holland; and the conditions of the treaty prove that an absurd point of honor was the only real cause for the short but bloody and ruinous war which plunged the Provinces into overwhelming difficulties.

For several years after the conclusion of this inglorious peace, universal discontent and dissension spread throughout the republic. The supporters of the House of Orange, and every impartial friend of the national honor, were indignant at the act of exclusion. Murmurs and revolts broke out in several towns; and all was once more tumult, agitation, and doubt. No event of considerable importance marks particularly this epoch of domestic trouble. A new war was at last pronounced inevitable, and was the means of appeasing the distractions of the people, and reconciling by degrees contending parties. Denmark, the ancient ally of the republic, was threatened with destruction by Charles Gustavus, king of Sweden, who held Copenhagen in blockade. The interests of Holland were in imminent peril should the Swedes gain the passage of the Sound. This double motive influenced De Witt; and he persuaded the states-general to send Admiral Opdam with a considerable fleet to the Baltic. This intrepid successor of the immortal Tromp soon came to blows with a rival worthy to meet him. Wrangel, the Swedish admiral, with a superior force, defended the passage of the Sound; and the two castles of Cronenberg and Elsenberg supported his fleet with their tremendous fire. But Opdam resolutely advanced; though suffering extreme anguish from an attack of gout, he had himself carried on deck, where he gave his orders with the most admirable coolness and precision, in the midst of danger and carnage. The rival monarchs witnessed the battle; the king of Sweden from the castle of Cronenberg, and the king of Denmark from the summit of the highest tower in his besieged capital. A brilliant victory crowned the efforts of the Dutch admiral, dearly bought by the death of his second in command, the brave De Witt, and Peter Florizon, another admiral of note. Relief was poured into Copenhagen. Opdam was replaced in the command, too arduous for his infirmities, by the still more celebrated De Ruyter, who was greatly distinguished by his valor in several successive affairs: and after some months more of useless obstinacy, the king of Sweden, seeing his army perish in the island of Funen, by a combined attack of those of Holland and Denmark, consented to a peace highly favorable to the latter power.

These transactions placed the United Provinces on a still higher pinnacle of glory than they had ever reached. Intestine disputes were suddenly calmed. The Algerines and other pirates were swept from the seas by a succession of small but vigorous expeditions. The mediation of the States re-established peace in several of the petty states of Germany. England and France were both held in check, if not preserved in friendship, by the dread of their recovered power. Trade and finance were reorganized. Everything seemed to promise a long-continued peace and growing greatness, much of which was owing to the talents and persevering energy of De Witt; and, to complete the good work of European tranquillity, the French and Spanish monarchs concluded in this year the treaty known by the name of the "peace of the Pyrenees."

Cromwell had now closed his career, and Charles II. was restored to the throne from which he had so long been excluded. The complimentary entertainments rendered to the restored king in Holland were on the proudest scale of expense. He left the country which had given him refuge in misfortune, and done him honor in his prosperity, with profuse expressions of regard and gratitude. Scarcely was he established in his recovered kingdom, when a still greater testimony of deference to his wishes was paid, by the states-general formally annulling the act of exclusion against the House of Orange. A variety of motives, however, acting on the easy and plastic mind of the monarch, soon effaced whatever of gratitude he had at first conceived. He readily entered into the views of the English nation, which was irritated by the great commercial superiority of Holland, and a jealousy excited by its close connection with France at this period.

It was not till the 22d of February, 1665, that war was formally declared against the Dutch; but many previous acts of hostility had taken place in expeditions against their settlements on the coast of Africa and in America, which were retaliated by De Ruyter with vigor and success. The Dutch used every possible means of avoiding the last extremities. De Witt employed all the powers of his great capacity to avert the evil of war; but nothing could finally prevent it, and the sea was once more to witness the conflict between those who claimed its sovereignty. A great battle was fought on the 31st of June. The duke of York, afterward James II., commanded the British fleet, and had under him the earl of Sandwich and Prince Rupert. The Dutch were led on by Opdam; and the victory was decided in favor of the English by the blowing up of that admiral's ship, with himself and his whole crew. The loss of the Dutch was altogether nineteen ships. De Witt the pensionary then took in person the command of the fleet, which was soon equipped; and he gave a high proof of the adaptation of genius to a pursuit previously unknown, by the rapid knowledge and the practical improvements he introduced into some of the most intricate branches of naval tactics.

Immense efforts were now made by England, but with a very questionable policy, to induce Louis XIV. to join in the war. Charles offered to allow of his acquiring the whole of the Spanish Netherlands, provided he would leave him without interruption to destroy the Dutch navy (and, consequently, their commerce), in the by no means certain expectation that its advantages would all fall to the share of England. But the king of France resolved to support the republic. The king of Denmark, too, formed an alliance with them, after a series of the most strange tergiversations. Spain, reduced to feebleness, and menaced with invasion by France, showed no alacrity to meet Charles's overtures for an offensive treaty. Van Galen, bishop of Munster, a restless prelate, was the only ally he could acquire. This bishop, at the head of a tumultuous force of twenty thousand men, penetrated into Friesland; but six thousand French were despatched by Louis to the assistance of the republic, and this impotent invasion was easily repelled.

The republic, encouraged by all these favorable circumstances, resolved to put forward its utmost energies. Internal discords were once more appeased; the harbors were crowded with merchant ships; the young Prince of Orange had put himself under the tuition of the states of Holland and of De Witt, who faithfully executed his trust; and De Ruyter was ready to lead on the fleet. The English, in spite of the dreadful calamity of the great fire of London, the plague which desolated the city, and a declaration of war on the part of France, prepared boldly for the shock.

The Dutch fleet, commanded by De Ruyter and Tromp, the gallant successor of his father's fame, was soon at sea. The English, under Prince Rupert and Monk, now duke of Albemarle, did not lie idle in port. A battle of four days continuance, one of the most determined and terrible up to this period on record, was the consequence. The Dutch claim, and it appears with justice, to have had the advantage. But a more decisive conflict took place on the 25th of July,[6] when a victory was gained by the English, the enemy having three of their admirals killed. "My God!" exclaimed De Ruyter; during this desperate fight, and seeing the certainty of defeat; "what a wretch I am! Among so many thousand bullets, is there not one to put an end to my miserable life?"
