Such were the characteristics of this famous siege during the winter and early spring. Alva might well write to his sovereign, that "it was a war such as never before was seen or heard of in any land on earth." Yet the Duke had known near sixty years of warfare. He informed Philip that "never was a place defended with such skill and bravery as Harlem, either by rebels or by men fighting for their lawful Prince." Certainly his son had discovered his mistake in asserting that the city would yield in a week; while the father, after nearly six years' experience, had found this "people of butter" less malleable than even those "iron people" whom he boasted of having tamed. It was seen that neither the skies of Greece or Italy, nor the sublime scenery of Switzerland, were necessary to arouse the spirit of defiance to foreign oppression—a spirit which beat as proudly among the wintry mists and the level meadows of Holland as it had ever done under sunnier atmospheres and in more romantic lands.
Mendoza had accomplished his mission to Spain, and had returned with supplies of money within six weeks from the date of his departure. Owing to his representations and Alva's entreaties, Philip had, moreover, ordered Requesens, governor of Milan, to send forward to the Netherlands three veteran Spanish regiments, which were now more required at Harlem than in Italy. While the land force had thus been strengthened, the fleet upon the lake had also been largely increased. The Prince of Orange had, on the other hand, provided more than a hundred sail of various descriptions, so that the whole surface of the mere was now alive with ships. Seafights and skirmishes took place almost daily, and it was obvious that the life and death struggle was now to be fought upon the water. So long as the Hollanders could hold or dispute the possession of the lake, it was still possible to succor Harlem from time to time. Should the Spaniards overcome the Prince's fleet, the city must inevitably starve.
At last, on the 28th of May, a decisive engagement of the fleets took place. The vessels grappled with each other, and there was a long, fierce, hand-to-hand combat. Under Bossu were one hundred vessels; under Martin Brand, admiral of the patriot fleet, nearly one hundred and fifty, but of lesser dimensions. Batenhurg commanded the troops on board the Dutch vessels. After a protracted conflict, in which several thousands were killed, the victory was decided in favor of the Spaniards. Twenty-two of the Prince's vessels being captured, and the rest totally routed, Bossu swept across the lake in triumph. The forts belonging to the patriots were immediately taken, and the Harlemers, with their friends, entirely excluded from the lake.
This was the beginning of the end. Despair took possession of the city. The whole population had been long subsisting upon an allowance of a pound of bread to each man, and half-a-pound for each woman; but the bread was now exhausted, the famine had already begun, and with the loss of the lake starvation was close at their doors. They sent urgent entreaties to, the Prince to attempt something in their behalf. Three weeks more they assigned as the longest term during which they could possibly hold out. He sent them word by carrier pigeons to endure yet a little time, for he was assembling a force, and would still succeed in furnishing them with supplies. Meantime, through the month of June the sufferings of the inhabitants increased hourly. Ordinary food had long since vanished. The population now subsisted on linseed and rape-seed; as these supplies were exhausted they devoured cats, dogs, rats, and mice, and when at last these unclean animals had been all consumed, they boiled the hides of horses and oxen; they ate shoe-leather; they plucked the nettles and grass from the graveyards, and the weeds which grew between the stones of the pavement, that with such food they might still support life a little longer, till the promised succor should arrive. Men, women, and children fell dead by scores in the streets, perishing of pure starvation, and the survivors had hardly the heart or the strength to bury them out of their sight. They who yet lived seemed to flit like shadows to and fro, envying those whose sufferings had already been terminated by death.
Thus wore away the month of June. On the 1st of July the burghers consented to a parley. Deputies were sent to confer with the besiegers, but the negotiations were abruptly terminated, for no terms of compromise were admitted by Don Frederic. On the 3rd a tremendous cannonade was re-opened upon the city. One thousand and eight balls were discharged—the most which had ever been thrown in one day, since the commencement of the siege. The walls were severely shattered, but the assault was not ordered, because the besiegers were assured that it was physically impossible for the inhabitants to hold out many days longer. A last letter, written in blood, was now despatched to the Prince of Orange, stating the forlorn condition to which they were reduced. At the same time, with the derision of despair, they flung into the hostile camp the few loaves of bread which yet remained within the city walls. A day or two later, a second and third parley were held, with no more satisfactory result than had attended the first. A black flag was now hoisted on the cathedral tower, the signal of despair to friend and foe, but a pigeon soon afterwards flew into the town with a letter from the Prince, begging them to maintain themselves two days longer, because succor was approaching.
The Prince had indeed been doing all which, under the circumstances, was possible. He assembled the citizens of Delft in the market-place, and announced his intention of marching in person to the relief of the city, in the face of the besieging army, if any troops could be obtained. Soldiers there were none; but there was the deepest sympathy for Harlem throughout its sister cities, Delft, Rotterdam, Gouda. A numerous mass of burghers, many of them persons of station, all people of respectability, volunteered to march to the rescue. The Prince highly disapproved of this miscellaneous army, whose steadfastness he could not trust. As a soldier, he knew that for such a momentous enterprise, enthusiasm could not supply the place of experience. Nevertheless, as no regular troops could be had, and as the emergency allowed no delay, he drew up a commission, appointing Paulus Buys to be governor during his absence, and provisional stadholder, should he fall in the expedition. Four thousand armed volunteers, with six hundred mounted troopers, under Carlo de Noot, had been assembled, and the Prince now placed himself at their head. There was, however, a universal cry of remonstrance from the magistracies and burghers of all the towns, and from the troops themselves, at this project. They would not consent that a life so precious, so indispensable to the existence of Holland, should be needlessly hazarded. It was important to succor Harlem, but the Prince was of more value than many cities. He at last reluctantly consented, therefore, to abandon the command of the expedition to Baron Batenburg, the less willingly from the want of confidence which he could not help feeling in the character of the forces. On the 8th of July, at dusk, the expedition set forth from Sassenheim. It numbered nearly five thousand men, who had with them four hundred wagon-loads of provisions and seven field-pieces. Among the volunteers, Oldenbarneveld; afterwards so illustrious in the history of the Republic; marched in the ranks, with his musket on his shoulder. Such was a sample of the spirit which pervaded the population of the province.
Batenburg came to a halt in the woods of Nordwyk, on the south aide of the city, where he remained till midnight. All seemed still in the enemy's camp. After prayers, he gave orders to push forward, hoping to steal through the lines of his sleeping adversaries and accomplish the relief by surprise. He was destined to be bitterly disappointed. His plans and his numbers were thoroughly known to the Spaniards, two doves, bearing letters which contained the details of the intended expedition, having been shot and brought into Don Frederic's camp.
The citizens, it appeared, had broken through the curtain work on the side where Batenburg was expected, in order that a sally might be made in co-operation with the relieving force, as soon as it should appear. Signal fires had been agreed upon, by which the besieged were to be made aware of the approach of their friends. The Spanish Commander accordingly ordered a mass of green branches, pitch, and straw, to be lighted opposite to the gap in the city wall. Behind it he stationed five thousand picked troops. Five thousand more, with a force of cavalry, were placed in the neighbourhood of the downs, with orders to attack the patriot army on the left. Six regiments, under Romero, were ordered to move eastward, and assail their right. The dense mass of smoke concealed the beacon lights displayed by Batenburg from the observation of the townspeople, and hid the five thousand Spaniards from the advancing Hollanders. As Batenburg emerged from the wood, he found himself attacked by a force superior to his own, while a few minutes later he was entirely enveloped by overwhelming numbers. The whole Spanish army was, indeed; under arms, and had been expecting him for two days. The unfortunate citizens alone were ignorant of his arrival. The noise of the conflict they supposed to be a false alarm created by the Spaniards, to draw them into their camp; and they declined a challenge which they were in no condition to accept.
Batenburg was soon slain, and his troops utterly routed. The number killed was variously estimated at from six hundred to two and even three thousand. It is, at any rate, certain that the whole force was entirely destroyed or dispersed, and the attempt to relieve the city completely frustrated. The death of Batenburg was the less regretted, because he was accused, probably with great injustice, of having been intoxicated at the time of action, and therefore incapable of properly, conducting the enterprise entrusted to him.
The Spaniards now cut off the nose and ears of a prisoner and sent him into the city, to announce the news, while a few heads were also thrown over the walls to confirm the intelligence. When this decisive overthrow became known in Delft, there was even an outbreak of indignation against Orange. According to a statement of Alva, which, however, is to be received with great distrust, some of the populace wished to sack the Prince's house, and offered him personal indignities. Certainly, if these demonstrations were made, popular anger was never more senseless; but the tale rests entirely, upon a vague assertion of the Duke, and is entirely, at variance with every other contemporaneous account of these transactions. It had now become absolutely, necessary, however, for the heroic but wretched town to abandon itself to its fate. It was impossible to attempt anything more in its behalf. The lake and its forts were in the hands of the enemy, the best force which could be mustered to make head against the besieging army had been cut to pieces, and the Prince of Orange, with a heavy heart, now sent word that the burghers were to make the best terms they could with the enemy.
