On the 8th September the stadholdet threw a bridge over the Rhine, and crossing that river and the Lippe, came on the 11th before Grol. There was no Christopher Mondragon now in his path to check his progress and spoil his campaign, so that in seventeen days the city, being completely surrounded with galleries and covered ways up to its walls, surrendered. Count van Stirum, royal governor of the place, dined with the stadholder on that day, and the garrison, from twelve hundred to fifteen hundred strong; together with such of the townsfolk as chose to be subjects of Philip rather than citizens of the republic, were permitted to depart in peace. On the 9th October the town and castle of Brevoort were taken by storm and the town was burned. On the 18th October, Maurice having summoned Enschede, the commandant requested permission to examine the artillery by which it was proposed to reduce the city. Leave being granted, two captains were deputed accordingly as inspectors, who reported that resistance was useless. The place accordingly capitulated at once. Here, again, was an improvement on the heroic practice of Alva and Romero. On the 21st and 22nd October, Ootmarsum and Oldenzaal were taken, and on the 28th the little army came before Lingen. This important city surrendered after a fortnight's siege. Thus closed a sagacious, business-like, three-months' campaign, in the course of which the stadholder, although with a slender force, had by means of his excellent organization and his profound practical science, achieved very considerable results. He had taken nine strongly-fortified cities and five castles, opened the navigation of the Rhine, and strengthened the whole eastern bulwarks of the republic. He was censured by the superficial critics of the old school for his humanity towards the conquered garrisons. At least it was thought quite superfluous to let these Spanish soldiers go scot free. Five thousand veterans had thus been liberated to swell the ranks of the cardinal's army, but the result soon proved the policy of Maurice to be, in many ways, wholesome. The great repudiation by Philip, and the consequent bankruptcy of Alberta converted large numbers of the royal troops into mutineers, and these garrisons from the eastern frontier were glad to join in the game.
