A storm broke upon Holland just as William was ripening into manhood; and discord at home threatened to aggravate the misfortunes of the country. The House of Orange had again become popular; and a loud cry was raised for the instant abolition of the Perpetual Edict, and for installing the young prince in all the offices enjoyed by his ancestors. The Republican party, headed by the De Witts, prevented this; but they were forced to yield to his being chosen captain-general and high-admiral. Many persons hoped that William's military rank and prospects would incline his uncle Charles II. to make common cause with the friends of liberty and independence; but the English monarch was the pensioner of the French king, and France and England jointly declared war against the States, April 7, 1672. The Dutch made large preparations; but new troops could not suddenly acquire discipline and experience. The enemy meditated, and had nearly effected, the entire conquest of the country; the populace became desperate; a total change of government was demanded; the De Witts were brutally massacred, and William was invested with the full powers of stadtholder. His fitness for this high office was soon demonstrated by the vigor and the wisdom of his measures. Maestricht was strongly garrisoned; the prince of Orange, with a large army, advanced to the banks of the Issel; the Dutch fleet cruised off the mouth of the Thames, to prevent the naval forces of England and France from joining. The following year, 1763, Louis XIV. took Maestricht; while the Prince of Orange, not having forces sufficient to oppose the French army, employed himself in retaking other towns from the enemy. New alliances were formed; and the prince's masterly conduct not only stopped the progress of the French, but forced them to evacuate the province of Utrecht. In 1674 the English Parliament compelled Charles II. to make peace with Holland. The Dutch signed separate treaties with the Bishop of Munster and the Elector of Cologne. The gallantry of the prince had so endeared him to the States of Holland, that the offices of stadtholder and captain-general were declared hereditary in his male descendants. Meanwhile he continued to display both courage and conduct in various military operations against the French. The battle of Seneffe was desperately fought. After sunset, the conflict was continued by the light of the moon; and darkness, rather than the exhaustion of the combatants, put an end to the contest, and left the victory undecided. The veteran Prince of Conde gave a candid and generous testimonial to the merit of his young antagonist: "The Prince of Orange," said he, "has in every point acted like an old captain, except in venturing his life too much like a young soldier."
