21. =Peace with the Dutch. 1674.=--The war with the Dutch was brought to an end by a treaty signed on February 19, =1674=. On the 24th Charles prorogued Parliament, and did not summon it again for more than a year. During the interval, he attempted to win friends all round, without committing himself to any definite policy. On the one hand, he remained on friendly terms with Louis, whilst, on the other hand, he offered the hand of Mary, the eldest child of his brother James, to her cousin, William of Orange. William's position was far higher than it had been two years before. He was now at the head of an alliance in which the Emperor Leopold, the King of Spain, and the Duke of Lorraine combined with him to restrain the inordinate ambition of Louis. It is true that his generalship was less conspicuous than his diplomacy, and that in the whole course of his life he never succeeded in beating a French army in the field. Yet even in war his indomitable courage and conspicuous coolness stood him in good stead, and he knew better than most commanders how to gather his troops after a defeat and to place them in strong positions in which the enemy did not dare to attack them. The history of Europe during the remainder of his life was the history of a duel between the ambitious and autocratic Louis and the cool-headed William, the first magistrate of a republic in which his action was checked by constitutional restraints on every side, and the head of a coalition of which the members were always prone to take offence and to pursue their individual interests at the sacrifice of the common good. To win England to the alliance was, for William, a most desirable object, but he knew that James might very well have a son by his second marriage, and, knowing that in that case he would reap no political advantage from a marriage with Mary, he for the present refused the offer of her hand.[31] [Footnote 31: Genealogy of some of the descendants of Charles I.:--
