In July, 1595, a serious misfortune befell the allied army. They had laid siege to Crolle, and had made considerable progress with the siege, when the Spanish army, under command of Mondragon, the aged governor of Antwerp, marched to its relief. As the army of Maurice was inferior in numbers, the States would not consent to a general action. The siege was consequently raised; and Mondragon having attained his object, fell back to a position on the Rhine at Orsoy, above Rheinberg, whence he could watch the movements of the allied army encamped on the opposite bank at Bislich, a few miles below Wesel. The Spanish army occupied both sides of the river, the wing on the right bank being protected from attack by the river Lippe, which falls into the Rhine at Wesel, and by a range of moorland hills called the Testerburg. The Dutch cavalry saw that the slopes of this hill were occupied by the Spaniards, but believed that their force consisted only of a few troops of horse. Young Count Philip of Nassau proposed that a body of cavalry should swim the Lippe, and attack and cut them off. Prince Maurice and Sir Francis Vere gave a very reluctant consent to the enterprise, but finally allowed him to take a force of five hundred men. With him were his brothers Ernest and Louis, his nephew Ernest de Solms, and many other nobles of Holland. Sir Marcellus Bacx was in command of them. The English contingent was commanded by Sir Nicholas Parker and Robert Vere. On August 22d they swam the Lippe and galloped in the direction where they expected to find two or three troops of Spanish horse; but Mondragon had received news of their intentions, and they suddenly saw before them half the Spanish army. Without hesitation the five hundred English and Dutch horsemen charged desperately into the enemy's ranks, and fought with extraordinary valour, until, altogether overpowered by numbers, Philip of Nassau and his nephew Ernest were both mortally wounded and taken prisoners. Robert Vere was slain by a lance-thrust in the face, and many other nobles and gentlemen fell. Thus died one of the three brave brothers, for the youngest, Horace, had also joined the army in 1590. The survivors of the band under Sir Nicholas Parker and Marcellus Bacx managed to effect their retreat, covered by a reserve Prince Maurice had posted on the opposite side of the river. CHAPTER XX.
