King William had felt deeply the disaster of his fleet. The news had reached him a few days after that of the battle of Fleurus, which had been won by the Marshal de Luxembourg from the Prince de Waldeck, commanding the allied forces. "I cannot express to you," wrote William to Heinsius, "how I am distressed at these two great great disasters which almost simultaneously have fallen upon the arms of the Republic. That of the fleet affects me the more deeply, because I have been informed that my vessels have not properly assisted those of the States, and left them in a critical position. I have ordered an inquiry to take place; the queen has given similar orders; no personal consideration shall prevent my rigorously punishing the guilty." William had a right to feel in the bottom of his soul a secret pride for his native country. The Dutch vessels had born the whole weight of the contest at Beachy Head, while the Marshal de Luxembourg wrote after the battle of Fleurus: "Prince de Waldeck will never forget the French cavalry, and I shall remember the Dutch infantry. It has done still better than the Spaniards at Rocroi."

The indignation of England was great against Admiral Herbert, created Lord Torrington, who was wrongfully accused of treason. An inquiry was held upon his conduct, and many people were found to be compromised in a Jacobite plot. Lord Clarendon, the queen's uncle, was of the number. Before his departure to Ireland the king had already had proof of his intrigues. The queen interceded for him. William had summoned Lord Rochester. "Your brother has plotted against me," he had said, "I am assured. I have been advised to except him from the amnesty, but I have been unwilling to cause this grief to the queen. It is for her sake that I forgive the past; but let Lord Clarendon take care in future; he will perceive that I am not jesting." This kind advice had not sufficed; Lord Clarendon's name was connected anew with Jacobite plots. The advisers of the queen hesitated to accuse him in her presence. "I know," said Mary, "and everybody knows as well as I, that Lord Clarendon is accused of things too grave to suffer him to be excepted from the precautionary measures." A warrant was signed for Clarendon's arrest. "I am more grieved for Lord Clarendon than people will believe," the queen wrote to her husband.

William returned to England, after meeting with a repulse before the walls of Limerick, defended by the Irish with the patriotic and sectarian zeal which had before animated the Protestant citizens of Londonderry. Lauzun and the auxiliary regiments, after withdrawing to Galway, had just embarked for France. King William bid Marlborough to make a descent upon Cork and Kinsale. The two places fell into the hands of that able general, and five weeks from his departure from Portsmouth he paid his respects to the king at Kensington. "There is not in Europe a general, having so little experience in war, who is worthier of great commands than the Earl of Marlborough," William said generously, for he did not like him. The return of the king, and his journey from Bristol to London, had been greeted with national transports of joy. He had left in Ireland the Dutch general Ginckel, a resolute and prudent man, at the head of an army, well disciplined, well equipped, and well victualled. Before the close of the following year, Ginckel had completed his task of pacifying Ireland. On the 20th of June, 1691, in spite of the presence and exertions of Saint-Ruth, who had come with reinforcements from France, he carried by storm the town of Athlone, the true key of Connaught, and the strongest place in Ireland. "His master should have him hanged for attempting to take Athlone," said the French general, "and my master can do the same to me, if I lose it." On the 12th of July Saint-Ruth was killed at the battle of Aghrim, and the Irish signally defeated. On the 26th of August, Ginckel laid siege to Limerick.

Tyrconnel had just breathed his last, old and prematurely worn out by fatigue and debauches. King James's troops were commanded by Lord Sarsfield, the most able and brilliant of the Irish officers. On the 1st of August a capitulation was signed, and was soon followed by a treaty. The Irish regiments were permitted to choose between the service of William and that of Louis XIV. A large number of soldiers went over spontaneously to France, forming in the armies of Louis XIV. and Louis XV. that Irish brigade, whose name has become famous. "Has this last campaign altered your opinion of our military qualities?" asked Sarsfield of the English officers. "To tell the truth," answered they, "we think almost the same of them as we have always thought." "Well," replied Sarsfield, "whatever bad opinion you may have of us, only let us change our king and begin again, and you will see." Ginckel was raised to the dignity of Earl of Athlone and Aghrim. King William and Parliament had ratified the terms offered by the general to the Irish; the struggle was over, the conquest consummated; the Protestant colonists, lately oppressed, became the masters, and often the oppressors of the indigenous race, which was dejected and decimated. Scotland was absorbed with the triumph of the Presbyterians, who had just legally recovered the religious supremacy in their country, to the great detriment of Episcopalians and Cameronians. The English Parliament had voted supplies generously, the Jacobite plots were exploded; the trial of Lord Torrington had ended in an acquittal, which never succeeded in erasing from the king's mind a distrust, which was merited by the dissolute life and known intemperance of the admiral. William had not waited for this first interval of domestic peace to respond to the needs of his soul, and the imperious call of political necessity. On the 18th of January, 1691, in spite of the severity of the season, he had embarked at Gravesend for Holland. "I yearn for this moment more than I can express to you," he wrote six months before to Heinsius.

The English fleet had arrived in sight of the coasts of Holland. The voyage had been unpleasant; disembarkation seemed impossible: enormous blocks of ice encumbered the channel, while a thick fog hid the land. For eighteen hours the four little ships were obliged to keep to sea. The king was, as usual, weak and suffering, yet he had wished to put off in an open boat, to gain his natal soil the quicker. The whole night was spent before he could step on dry land; the cold was intense, and the danger serious. Some of the sailors were in despair. "Fie!" said William to them, "are you afraid to die with me?" Some great British noblemen, the Dukes of Ormond and Norfolk, the Earls of Devonshire, Dorset and Monmouth, were with him; Portland and Zulestein were glad to accompany their beloved sovereign to Holland. It was only at daybreak, by the feeble light of a winter's morning, that they were able at last to land on the island of Goree. The king rested there some hours before taking the road to the Hague.

Joy beamed on the face which the English were accustomed to find stern and haughty. Heart was responding to heart; England had accepted its deliverance from the hand of William III., without affinity for him and through necessity. The Dutch loved the heir of the greatest name in their nation and of their race, the liberator of their country, the man who had carried to the throne of England the glory, the name and the manners of his Dutch fatherland. The people pressed upon his steps. "Let them alone," said the king; "let them come near me and all be my friends." A splendid reception had been prepared at the Hague: he was opposed to the pageant and the ceremonies, and murmured against this useless expenditure. "It is quite enough to have to bear the cost of the war," he observed. His countrymen spared him neither a speech nor a salvo of artillery; the joy of the population was at its height. "It would be quite another thing if Mary had accompanied me," said the king to those who congratulated him upon his triumph; "she is more popular than I."

The States-General were solemnly convened. William was more moved than he had been formerly on leaving his native country. "When I took leave of you," he said, "I informed you of my intention to cross over to England, to save, thanks to your aid, that kingdom from a deluge of evils present and to come. Providence has blessed my enterprise, and the nation has offered me the crown of the three kingdoms. I have accepted it, not from ambition, God is my witness, but to put the religion, the welfare, the peace of Great Britain beyond the power of any assault, and to be able to protect the allies, the republic in particular, against the supremacy of France. I have loved this country from my earliest youth, and, if anything could increase this love, it is the certainty that I have found a reciprocal attachment in the hearts of my countrymen. If it pleases God that I should become the instrument which Providence may deign to use in order to restore repose to Europe and re-establish security in your state, I shall have lived long enough and shall go down tranquilly to the grave."
