A fresh treaty was made between England and the Netherlands, Sir Francis Vere being sent out as special ambassador to negotiate. England was anxious for peace, but would not desert the Netherlands if they on their part would relieve her to some extent of the heavy expenses caused by the war. This the States consented to do, and the treaty was duly signed on both sides. A few days before its conclusion Lord Burleigh, who had been Queen Elizabeth's chief adviser for forty years, died, and within a month of its signature Philip of Spain, whose schemes he had so long opposed, followed him to the grave. On the 6th of the previous May Philip had formally ceded the Netherlands to his daughter Isabella, between whom and the Archduke Albert a marriage had been arranged. This took place on the 18th of April following, shortly after his death. It was celebrated at Valencia, and at the same time King Philip III was united to Margaret of Austria. In the course of 1599 there was severe fighting on the swampy island between the rivers Waal and Maas, known as the Bommel Waat, and a fresh attempt at invasion by the Spaniards was repulsed with heavy loss, Sir Francis Vere and the English troops taking a leading part in the operations. The success thus gained decided the States General to undertake an offensive campaign in the following year. The plan they decided upon was opposed both by Prince Maurice and Sir Francis Vere as being altogether too hazardous; but the States, who upon most occasions were averse to anything like bold action, upon the present occasion stood firm to their decision. Their plan was to land an army near Ostend, which was held by the English, and to besiege the town of Nieuport, west of Ostend, and after that to attack Dunkirk. In the opinion of the two generals an offensive operation direct from Holland would have been far preferable, as in case of disaster the army could fall back upon one of their fortified towns, whereas, if beaten upon the coast, they might be cut off from Ostend and entirely destroyed. However, their opinions were overruled, and the expedition prepared. It consisted of 12,000 infantry, 1600 cavalry, and 10 guns. It was formed into three divisions. The van, 4500 strong, including 1600 English veterans, was commanded by Sir Francis Vere; the second division by Count Everard Solms; the rear division by Count Ernest of Nassau; while Count Louis Gunther of Nassau was in command of the cavalry. The army embarked at Flushing, and landed at Philippine, a town at the head of the Braakeman inlet. There was at the time only a small body of Spaniards in the neighbourhood, but as soon as the news reached the Archduke Albert at Brussels he concentrated his army round Ghent. The troops had for some time been in a mutinous state, but, as was always the case with them, they returned to their habits of military obedience the moment danger threatened.
