William saw with stern delight his adversaries toiling to clear away obstacle after obstacle from his path. While they raised against themselves the enmity of all sects, he laboured to conciliate all. The great design which he meditated, he with exquisite skill presented to different governments in different lights; and it must be added that, though those lights were different, none of them was false. He called on the princes of Northern Germany to rally round him in defence of the common cause of all reformed Churches. He set before the two heads of the House of Austria the danger with which they were threatened by French ambition, and the necessity of rescuing England from vassalage and of uniting her to the European confederacy.453 He disclaimed, and with truth, all bigotry. The real enemy, he said, of the British Roman Catholics was that shortsighted and headstrong monarch who, when he might easily have obtained for them a legal toleration, had trampled on law, liberty, property, in order to raise them to an odious and precarious ascendency. If the misgovernment of James were suffered to continue, it must produce, at no remote time, a popular outbreak, which might be followed by a barbarous persecution of the Papists. The Prince declared that to avert the horrors of such a persecution was one of his chief objects. If he succeeded in his design, he would use the power which he must then possess, as head of the Protestant interest, to protect the members of the Church of Rome. Perhaps the passions excited by the tyranny of James might make it impossible to efface the penal laws from the statute book but those laws should be mitigated by a lenient administration. No class would really gain more by the proposed expedition than those peaceable and unambitious Roman Catholics who merely wished to follow their callings and to worship their Maker without molestation. The only losers would be the Tyrconnels, the Dovers, the Albevilles, and the other political adventurers who, in return for flattery and evil counsel, had obtained from their credulous master governments, regiments, and embassies.
While William exerted himself to enlist on his side the sympathies both of Protestants and of Roman Catholics, he exerted himself with not less vigour and prudence to provide the military means which his undertaking required. He could not make a descent on England without the sanction of the United Provinces. If he asked for that sanction before his design was ripe for execution, his intentions might possibly be thwarted by the faction hostile to his house, and would certainly be divulged to the whole world.
He therefore determined to make his preparations with all speed, and, when they were complete, to seize some favourable moment for requesting the consent of the federation. It was observed by the agents of France that he was more busy than they had ever known him. Not a day passed on which he was not seen spurring from his villa to the Hague. He was perpetually closeted with his most distinguished adherents. Twenty-four ships of war were fitted out for sea in addition to the ordinary force which the commonwealth maintained. There was, as it chanced, an excellent pretence for making this addition to the marine: for some Algerine corsairs had recently dared to show themselves in the German Ocean. A camp was formed near Nimeguen. Many thousands of troops were assembled there. In order to strengthen this army the garrisons were withdrawn from the strongholds in Dutch Brabant. Even the renowned fortress of Bergopzoom was left almost defenceless.
Field pieces, bombs, and tumbrels from all the magazines of the United Provinces were collected at the head quarters. All the bakers of Rotterdam toiled day and night to make biscuit. All the gunmakers of Utrecht were found too few to execute the orders for pistols and muskets. All the saddlers of Amsterdam were hard at work on harness and bolsters. Six thousand sailors were added to the naval establishment. Seven thousand new soldiers were raised.
