A little before midnight Captain Heraugière told his comrades that the hour had arrived, and that only by the most desperate bravery could they hope to succeed, while death was the certain consequence of failure. The band were divided into two companies. He himself with one was to attack the main guardhouse; the other, under Fervet, was to seize the arsenal of the fortress. Noiselessly they stole out from their hiding-place, and formed upon the wharf within the inclosure of the castle. Heraugière moved straight upon the guard-house. The sentry was secured instantly; but the slight noise was heard, and the captain of the watch ran out but was instantly cut down.

Others came out with torches, but after a brief fight were driven into the guard-house; when all were shot down through the doors and windows. Captain Fervet and his band had done equally well. The magazine of the castle was seized, and its defenders slain. Paolo Lanzavecchia made a sally from the palace with a few of his adherents, but was wounded and driven back; and the rest of the garrison of the castle, ignorant of the strength of the force that had thus risen as it were from the earth upon them, fled panic-stricken, not even pausing to destroy the bridge between the castle and the town.

Young Paolo Lanzavecchia now began a parley with the assailants; but while the negotiations were going on Hohenlohe with his cavalry came up—having been apprised by the boatman that the attempt was about to be made—battered down the palisade near the water-gate, and entered the castle. A short time afterwards Prince Maurice, Sir Francis Vere, and other officers arrived with the main body of the troops. But the fight was over before even Hohenlohe arrived; forty of the garrison being killed, and not a single man of the seventy assailants. The burgomaster, finding that the castle had fallen, and that a strong force had arrived, then sent a trumpeter to the castle to arrange for the capitulation of the town, which was settled on the following terms:—All plundering was commuted for the payment of two months' pay to every soldier engaged in the affair. All who chose might leave the city, with full protection to life and property. Those who were willing to remain were not to be molested in their consciences or households with regard to religion.

The news of the capture of Breda was received with immense enthusiasm throughout Holland. It was the first offensive operation that had been successfully undertaken, and gave new hope to the patriots.

Parma was furious at the cowardice with which five companies of foot and one of horse—all picked troops—had fled before the attack of seventy Hollanders. Three captains were publicly beheaded in Brussels and a fourth degraded to the ranks, while Lanzavecchia was deprived of the command of Gertruydenberg.

For some months before the assault upon Breda the army of Holland had been gaining vastly in strength and organization. Prince Maurice, aided by his cousin Lewis William, stadholder of Friesland, had been hard at work getting it into a state of efficiency. Lewis William, a man of great energy and military talent, saw that the use of solid masses of men in the field was no longer fitted to a state of things when the improvements in firearms of all sorts had entirely changed the condition of war. He therefore reverted to the old Roman methods, and drilled his soldiers in small bodies; teaching them to turn and wheel, advance or retreat, and perform all sorts of manoeuvres with regularity and order. Prince Maurice adopted the same plan in Holland, and the tactics so introduced proved so efficient that they were sooner or later adopted by all civilized nations.

At the time when William of Orange tried to relieve the hard-pressed city of Haarlem, he could with the greatest difficulty muster three or four thousand men for the purpose. The army of the Netherlands was now 22,000 strong, of whom 2000 were cavalry. It was well disciplined, well equipped, and regularly paid, and was soon to prove that the pains bestowed upon it had not been thrown away. In the course of the eighteen years that had followed the capture of Brill and the commencement of the struggle with Spain, the wealth and prosperity of Holland had enormously increased. The Dutch were masters of the sea-coast, the ships of the Zeelanders closed every avenue to the interior, and while the commerce of Antwerp, Ghent, Bruges, and the other cities of the provinces that remained in the hands of the Spaniards was for the time destroyed, and their population fell off by a half, Holland benefited in proportion.

From all the Spanish provinces men of energy and wealth passed over in immense numbers to Holland, where they could pursue their commerce and industries—free from the exactions and cruelty under which they had for so many years groaned. The result was that the cities of Holland increased vastly in wealth and population, and the resources at the disposal of Prince Maurice enormously exceeded those with which his father had for so many years sustained the struggle.

For a while after the capture of Breda there was breathing time in Holland, and Maurice was busy in increasing and improving his army. Parma was fettered by the imperious commands of Philip, who had completely crippled him by withdrawing a considerable number of his troops for service in the war which he was waging with France. But above all, the destruction of the Armada, and with it of the naval supremacy of Spain, had changed the situation.

Holland was free to carry on her enterprises by sea, and had free communication and commerce with her English ally, while communication between Spain and the Netherlands was difficult. Reinforcements could no longer be sent by sea, and had to be sent across Europe from Italy. Parma was worn out by exertions, disappointment, and annoyance, and his health was seriously failing; while opposed to him were three young commanders—Maurice, Lewis William, and Francis Vere—all men of military genius and full of confidence and energy.
