Deventer and Kampen, the two other places on the river, were in the hands of the States. It was, therefore, desirable for the English and the patriots, by gaining possession of Zutphen, to obtain control of the Yssel; driven, as they had been, from the Meuse and Rhine. Sir John Norris, by Leicester's direction, took possession of a small rising-ground, called 'Gibbet Dill' on the land-side; where he established a fortified camp, and proceeded to invest the city. With him were Count Lewis William of Nassau, and Sir Philip Sidney, while the Earl himself, crossing the Yssel on a bridge of boats which he had constructed, reserved for himself the reduction of the forts upon the Veluwe side. Farnese, meantime, was not idle; and Leicester's calculations proved correct. So soon as the Prince was informed of this important demonstration of the enemy he broke up--after brief debate with his officers--his camp before Rheinberg, and came to Wesel. At this place he built a bridge over the Rhine, and fortified it with two block-houses. These he placed under command of Claude Berlot, who was ordered to watch strictly all communication up the river with the city of Rheinberg, which he thus kept in a partially beleaguered state. Alexander then advanced rapidly by way of Groll and Burik, both which places he took possession of, to the neighbourhood of Zutphen. He was determined, at every hazard, to relieve that important city; and although, after leaving necessary detachments on the way; he had but five thousand men under his command, besides fifteen hundred under Verdugo--making sixty-five hundred in all--he had decided that the necessity of the case, and his own honour; required him to seek the enemy, and to leave, as he said, the issue with the God of battles, whose cause it was. Tassis, lieutenant-governor of Gelderland, was ordered into the city with two cornets of horse and six hundred foot. As large a number, had already been stationed there. Verdugo, who had been awaiting the arrival of the Prince at Borkelo, a dozen miles from Zutphen, with four hundred foot and two hundred horse, now likewise entered the city.
