At the news of this invasion the archdukes, though taken by surprise, displayed a promptness and decision that proved them worthy of the sovereignty which seemed at stake. With incredible activity they mustered, in a few days, an army of twelve thousand men, which they passed in review near Ghent. On this occasion Isabella, proving her title to a place among those heroic women with whom the age abounded, rode through the royalist ranks, and harangued them in a style of inspiring eloquence that inflamed their courage and secured their fidelity. Albert, seizing the moment of this excitement, put himself at their head, and marched to seek the enemy, leaving his intrepid wife at Bruges, the nearest town to the scene of the action he was resolved on. He gained possession of all the forts taken and garrisoned by Maurice a few days before; and pushing forward with his apparently irresistible troops, he came up on the morning of the 2d of July with a large body of those of the states, consisting of about three thousand men, sent forward under the command of Count Ernest of Nassau to reconnoitre and judge of the extent of this most unexpected movement: for Prince Maurice was, in his turn, completely surprised; and not merely by one of those manoeuvres of war by which the best generals are sometimes deceived, but by an exertion of political vigor and capacity of which history offers few more striking examples. Such a circumstance, however, served only to draw forth a fresh display of those uncommon talents which in so many various accidents of war had placed Maurice on the highest rank for military talent. The detachment under Count Ernest of Nassau was chiefly composed of Scottish infantry; and this small force stood firmly opposed to the impetuous attack of the whole royalist army--thus giving time to the main body under the prince to take up a position, and form in order of battle. Count Ernest was at length driven back, with the loss of eight hundred men killed, almost all Scottish; and being cut off from the rest of the army, was forced to take refuge in Ostend, which town was in possession of the troops of the states.
