Orange had returned to Antwerp early in February. During his absence, Hoogstraaten had acted as governor at the instance of the Prince and of the Regent. During the winter that nobleman, who was very young and very fiery, had carried matters with a high hand, whenever there had been the least attempt at sedition. Liberal in principles, and the devoted friend of Orange, he was disposed however to prove that the champions of religious liberty were not the patrons of sedition. A riot occurring in the cathedral, where a violent mob were engaged in defacing whatever was left to deface in that church, and in heaping insults on the papists at their worship, the little Count, who, says a Catholic contemporary, "had the courage of a lion," dashed in among them, sword in hand, killed three upon the spot, and, aided by his followers, succeeded in slaying, wounding, or capturing all the rest. He had also tracked the ringleader of the tumult to his lodging, where he had caused him to be arrested at midnight, and hanged at once in his shirt without any form of trial. Such rapid proceedings little resembled the calm and judicious moderation of Orange upon all occasions, but they certainly might have sufficed to convince Philip that all antagonists of the inquisition were not heretics and outlaws. Upon the arrival of the Prince in Antwerp, it was considered advisable that Hoogstraaten should remain associated with him in the temporary government of the city.
During the month of February, Brederode remained in Antwerp, secretly enrolling troops. It was probably his intention—if so desultory and irresponsible an individual could be said to have an intention—to make an attempt upon the Island of Walcheren. If such important cities as Flushing and Middelburg could be gained, he thought it possible to prevent the armed invasion now soon expected from Spain. Orange had sent an officer to those cities, who was to reconnoitre their condition, and to advise them against receiving a garrison from government without his authority. So far he connived at Brederode's proceedings, as he had a perfect right to do, for Walcheren was within what had been the Prince's government, and he had no disposition that these cities should share the fate of Tourney, Valenciennes, Bois le Duc, and other towns which had already passed or were passing under the spears of foreign mercenaries.
It is also probable that he did not take any special pains to check the enrolments of Brederode. The peace of Antwerp was not endangered, and to the preservation of that city the Prince seemed now to limit himself. He was hereditary burgrave of Antwerp, but officer of Philip's never more. Despite the shrill demands of Duchess Margaret, therefore; the Prince did not take very active measures by which the crown of Philip might be secured. He, perhaps, looked upon the struggle almost with indifference. Nevertheless, he issued a formal proclamation by which the Count's enlistments were forbidden. Van der Aa, a gentleman who had been active in making these levies, was compelled to leave the city. Brederode was already gone to the north to busy himself with further enrolments.
In the mean time there had been much alarm in Brussels. Egmont, who omitted no opportunity of manifesting his loyalty, offered to throw himself at once into the Isle of Walcheren, for the purpose of dislodging any rebels who might have effected an entrance. He collected accordingly seven or eight hundred Walloon veterans, at his disposal in Flanders, in the little port of Sas de Ghent, prepared at once to execute his intention, "worthy," says a Catholic writer, "of his well-known courage and magnanimity." The Duchess expressed gratitude for the Count's devotion and loyalty, but his services in the sequel proved unnecessary. The rebels, several boat-loads of whom had been cruising about in the neighborhood of Flushing during the early part of March, had been refused admittance into any of the ports on the island. They therefore sailed up the Scheld, and landed at a little village called Ostrawell, at the distance of somewhat more than a mile from Antwerp.
The commander of the expedition was Marnix of Tholouse, brother to Marnix of Saint Aldegonde. This young nobleman, who had left college to fight for the cause of religious liberty, was possessed of fine talents and accomplishments. Like his illustrious brother, he was already a sincere convert to the doctrines of the reformed Church. He had nothing, however, but courage to recommend him as a leader in a military expedition. He was a mere boy, utterly without experience in the field. His troops were raw levies, vagabonds and outlaws.
Such as it was, however, his army was soon posted at Ostrawell in a convenient position, and with considerable judgment. He had the Scheld and its dykes in his rear, on his right and left the dykes and the village. In front he threw up a breastwork and sunk a trench. Here then was set up the standard of rebellion, and hither flocked daily many malcontents from the country round. Within a few days three thousand men were in his camp. On the other handy Brederode was busy in Holland, and boasted of taking the field ere long with six thousand soldiers at the very least. Together they would march to the relief of Valenciennes, and dictate peace in Brussels.
It was obvious that this matter could not be allowed to go on. The Duchess, with some trepidation, accepted the offer made by Philip de Lannoy, Seigneur de Beauvoir, commander of her body-guard in Brussels, to destroy this nest of rebels without delay. Half the whole number of these soldiers was placed at his disposition, and Egmont supplied De Beauvoir with four hundred of his veteran Walloons.
With a force numbering only eight hundred, but all picked men, the intrepid officer undertook his enterprise, with great despatch and secrecy. Upon the 12th March, the whole troop was sent off in small parties, to avoid suspicion, and armed only with sword and dagger. Their helmets, bucklers, arquebusses, corselets, spears, standards and drums, were delivered to their officers, by whom they were conveyed noiselessly to the place of rendezvous. Before daybreak, upon the following morning, De Beauvoir met his soldiers at the abbey of Saint Bernard, within a league of Antwerp. Here he gave them their arms, supplied them with refreshments, and made them a brief speech. He instructed them that they were to advance, with furled banners and without beat of drum, till within sight of the enemy, that the foremost section was to deliver its fire, retreat to the rear and load, to be followed by the next, which was to do the same, and above all, that not an arquebus should be discharged till the faces of the enemy could be distinguished.
The troop started. After a few minutes' march they were in full sight of Ostrawell. They then displayed their flags and advanced upon the fort with loud huzzas. Tholouse was as much taken by surprise as if they had suddenly emerged from the bowels of the earth. He had been informed that the government at Brussels was in extreme trepidation. When he first heard the advancing trumpets and sudden shouts, he thought it a detachment of Brederode's promised force. The cross on the banners soon undeceived him. Nevertheless "like a brave and generous young gentleman as he was," he lost no time in drawing up his men for action, implored them to defend their breastworks, which were impregnable against so small a force, and instructed them to wait patiently with their fire, till the enemy were near enough to be marked.
These orders were disobeyed. The "young scholar," as De Beauvoir had designated him, had no power to infuse his own spirit into his rabble rout of followers. They were already panic-struck by the unexpected appearance of the enemy. The Catholics came on with the coolness of veterans, taking as deliberate aim as if it had been they, not their enemies, who were behind breastworks. The troops of Tholouse fired wildly, precipitately, quite over the heads of the assailants. Many of the defenders were slain as fast as they showed themselves above their bulwarks. The ditch was crossed, the breastwork carried at, a single determined charge. The rebels made little resistance, but fled as soon as the enemy entered their fort. It was a hunt, not a battle. Hundreds were stretched dead in the camp; hundreds were driven into the Scheld; six or eight hundred took refuge in a farm-house; but De Beauvoir's men set fire to the building, and every rebel who had entered it was burned alive or shot. No quarter was given. Hardly a man of the three thousand who had held the fort escaped. The body of Tholouse was cut into a hundred pieces. The Seigneur de Beauvoir had reason, in the brief letter which gave an account of this exploit, to assure her Highness that there were "some very valiant fellows in his little troop." Certainly they had accomplished the enterprise entrusted to them with promptness, neatness, and entire success. Of the great rebellious gathering, which every day had seemed to grow more formidable, not a vestige was left.
