Certainly, such language was not becoming the pen which wrote the famous Compromise. The Prince himself was, however, not to be induced, even by the captivity and the remonstrances of so valued a friend, to swerve from the path of duty. He still maintained, in public and private, that the withdrawal of foreign troops from the provinces, the restoration of the old constitutional privileges, and the entire freedom of conscience in religious matters, were the indispensable conditions of any pacification. It was plain to him that the Spaniards were not ready to grant these conditions; but he felt confident that he should accomplish the release of Saint Aldegonde without condescending to an ignominious peace.
The most pressing matter, upon the Great Commander's arrival, was obviously to relieve the city of Middelburg. Mondragon, after so stanch a defence, would soon be obliged to capitulate, unless he should promptly receive supplies. Requesens, accordingly, collected seventy-five ships at Bergen op Zoom; which were placed nominally under the command of Admiral de Glimes, but in reality under that of Julian Romero. Another fleet of thirty vessels had been assembled at Antwerp under Sancho d'Avila. Both, amply freighted with provisions, were destined to make their way to Middelburg by the two different passages of the Hondo and the Eastern Scheld. On the other hand, the Prince of Orange had repaired to Flushing to superintend the operations of Admiral Boisot, who already; in obedience to his orders, had got a powerful squadron in readiness at that place. Late in January, 1574, d'Avila arrived in the neighbourhood of Flushing, where he awaited the arrival of Romero's fleet. United, the two Commanders were to make a determined attempt to reinforce the starving city of Middelburg. At the same time, Governor Requesens made his appearance in person at Bergen op Zoom to expedite the departure of the stronger fleet, but it was not the intention of the Prince of Orange to allow this expedition to save the city. The Spanish generals, however valiant, were to learn that their genius was not amphibious, and that the Beggars of the Sea were still invincible on their own element, even if their brethren of the land had occasionally quailed.
Admiral Boisot's fleet had already moved up the Scheld and taken a position nearly opposite to Bergen op Zoom. On the 20th of January the Prince of Orange, embarking from Zierick Zee, came to make them a visit before the impending action. His galley, conspicuous for its elegant decorations, was exposed for some time to the artillery of the fort, but providentially escaped unharmed. He assembled all the officers of his armada, and, in brief but eloquent language, reminded them how necessary it was to the salvation of the whole country that they should prevent the city of Middelburg—the key to the whole of Zealand, already upon the point of falling into the hands of the patriots—from being now wrested from their grasp. On the sea, at least, the Hollanders and Zealanders were at home. The officers and men, with one accord, rent the air with their cheers. They swore that they would shed every drop of blood in their veins but they would sustain the Prince and the country; and they solemnly vowed not only to serve, if necessary, without wages, but to sacrifice all that they possessed in the world rather than abandon the cause of their fatherland. Having by his presence and his language aroused their valor to so high a pitch of enthusiasm, the Prince departed for Delft, to make arrangements to drive the Spaniards from the siege of Leyden.
On the 29th of January, the fleet of Romero sailed from Bergen, disposed in three divisions, each numbering twenty-five vessels of different sizes. As the Grand Commander stood on the dyke of Schakerloo to witness the departure, a general salute was fired by the fleet in his honor, but with most unfortunate augury. The discharge, by some accident, set fire to the magazines of one of the ships, which blew up with a terrible explosion, every soul on board perishing. The expedition, nevertheless, continued its way. Opposite Romerswael, the fleet of Boisot awaited them, drawn up in battle array. As an indication of the spirit which animated this hardy race, it may be mentioned that Schot, captain of the flag-ship, had been left on shore, dying of a pestilential fever. Admiral Boisot had appointed a Flushinger, Klaaf Klaafzoon, in his place. Just before the action, however, Schot, "scarcely able to blow a feather from his mouth," staggered on board his ship, and claimed the command.
There was no disputing a precedency which he had risen from his death-bed to vindicate. There was, however, a short discussion, as the enemy's fleet approached, between these rival captains regarding the manner in which the Spaniards should be received. Klaafzoon was of opinion that most of the men should go below till after the enemy's first discharge. Schot insisted that all should remain on deck, ready to grapple with the Spanish fleet, and to board them without the least delay.
The sentiment of Schot prevailed, and all hands stood on deck, ready with boarding-pikes and grappling-irons.
The first division of Romero came nearer, and delivered its first broadside, when Schot and Klaafzoon both fell mortally wounded. Admiral Boisot lost an eye, and many officers and sailors in the other vessels were killed or wounded. This was, however, the first and last of the cannonading. As many of Romero's vessels as could be grappled within the narrow estuary found themselves locked in close embrace with their enemies. A murderous hand-to-hand conflict succeeded. Battle-axe, boarding-pike, pistol, and dagger were the weapons. Every man who yielded himself a prisoner was instantly stabbed and tossed into the sea by the remorseless Zealanders. Fighting only to kill, and not to plunder, they did not even stop to take the gold chains which many Spaniards wore on their necks. It had, however, been obvious from the beginning that the Spanish fleet were not likely to achieve that triumph over the patriots which was necessary before they could relieve Middelburg. The battle continued a little longer; but after fifteen ships had been taken and twelve hundred royalists slain, the remainder of the enemy's fleet retreated into Bergen. Romero himself, whose ship had grounded, sprang out of a port-hole and swam ashore, followed by such of his men as were able to imitate him. He landed at the very feet of the Grand Commander, who, wet and cold, had been standing all day upon the dyke of Schakerloo, in the midst of a pouring rain, only to witness the total defeat of his armada at last.
"I told your Excellency," said Romero, coolly, as he climbed, all dripping, on the bank, "that I was a land-fighter and not a sailor. If you were to give me the command of a hundred fleets, I believe that none of them would fare better than this has done." The Governor and his discomfited, but philosophical lieutenant, then returned to Bergen, and thence to Brussels, acknowledging that the city of Middelburg must fall, while Sancho d'Avila, hearing of the disaster which had befallen his countrymen, brought his fleet, with the greatest expedition, back to Antwerp. Thus the gallant Mondragon was abandoned to his fate.
That fate could no longer be protracted. The city of Middelburg had reached and passed the starvation point. Still Mondragon was determined not to yield at discretion, although very willing to capitulate. The Prince of Orange, after the victory of Bergen, was desirous of an unconditional surrender, believing it to be his right, and knowing that he could not be supposed capable of practising upon Middelburg the vengeance which had been wreaked on Naarden, Zutfen, and Harlem. Mondragon, however, swore that he would set fire to the city in twenty places, and perish with every soldier and burgher in the flames together, rather than abandon himself to the enemy's mercy. The prince knew that the brave Spaniard was entirely capable of executing his threat. He granted honorable conditions, which, on the 18th February, were drawn up in five articles, and signed. It was agreed that Mondragon and his troops should leave the place, with their arms, ammunition, and all their personal property. The citizens who remained were to take oath of fidelity to the Prince, as stadholder for his Majesty, and were to pay besides a subsidy of three hundred thousand florins. Mondragon was, furthermore, to procure the discharge of Saint Aldegonde, and of four other prisoners of rank, or, failing in the attempt, was to return within two months, and constitute himself prisoner of war. The Catholic priests were to take away from the city none of their property but their clothes. In accordance with this capitulation, Mondragon, and those who wished to accompany him, left the city on the 21st of February, and were conveyed to the Flemish shore at Neuz. It will be seen in the sequel that the Governor neither granted him the release of the five prisoners, nor permitted him to return, according to his parole. A few days afterwards, the Prince entered the city, re-organized the magistracy, received the allegiance of the inhabitants, restored the ancient constitution, and liberally remitted two-thirds of the sum in which they had been, mulcted.
The Spaniards had thus been successfully driven from the Isle of Walcheren, leaving the Hollanders and Zealanders masters of the sea-coast. Since the siege of Alkmaar had been raised, however, the enemy had remained within the territory of Holland. Leyden was closely invested, the country in a desperate condition, and all communication between its different cities nearly suspended. It was comparatively easy for the Prince of Orange to equip and man his fleets. The genius and habits of the people made them at home upon the water, and inspired them with a feeling of superiority to their adversaries. It was not so upon land. Strong to resist, patient to suffer, the Hollanders, although terrible in defence; had not the necessary discipline or experience to meet the veteran legions of Spain, with confidence in the open field. To raise the siege of Leyden, the main reliance of the Prince was upon Count Louis, who was again in Germany. In the latter days of Alva's administration, William had written to his brothers, urging them speedily to arrange the details of a campaign, of which he forwarded them a sketch. As soon as a sufficient force had been levied in Germany, an attempt was to be made upon Maestricht. If that failed, Louis was to cross the Meuse, in the neighbourhood of Stochem, make his way towards the Prince's own city of Gertruidenberg, and thence make a junction with his brother in the neighbourhood of Delft. They were then to take up a position together between Harlem and Leyden. In that case it seemed probable that the Spaniards would find themselves obliged to fight at a great disadvantage, or to abandon the country. "In short," said the Prince, "if this enterprise be arranged with due diligence and discretion, I hold it as the only certain means for putting a speedy end to the war, and for driving these devils of Spaniards out of the country, before the Duke of Alva has time to raise another army to support them."
