In the undertaking of the 5th of April all had been accomplished that human ingenuity could devise; yet the triumph had been snatched away even at the very moment when it was complete. A determined and vigorous effort was soon to be made upon the Kowenstyn, in the very face of Parma; for it now seemed obvious that the true crisis was to come upon that fatal dyke. The great bulwark was three miles long. It reached from Stabroek in Brabant, near which village Mansfeld's troops were encamped, across the inundated country, up to the line of the Scheldt. Thence, along the river-dyke, and across the bridge to Kalloo and Beveren, where Parma's forces lay, was a continuous fortified road some three leagues in length; so that the two divisions of the besieging army, lying four leagues apart, were all connected by this important line.
Could the Kowenstyn be pierced, the water, now divided by that great bulwark into two vast lakes, would flow together in one continuous sea. Moreover the Scheldt, it was thought, would, in that case, return to its own cannel through Brabant, deserting its present bed, and thus leaving the famous bridge high and dry. A wide sheet of navigable water would then roll between Antwerp and the Zeeland coasts, and Parma's bridge, the result of seven months' labour, would become as useless as a child's broken toy.
Alexander had thoroughly comprehended the necessity of maintaining the Kowenstyn. All that it was possible to do with the meagre forces at his disposal, he had done. He had fringed both its margins, along its whole length, with a breastwork of closely-driven stakes. He had strengthened the whole body of the dyke with timber-work and piles. Upon its river-end, just at the junction with the great Scheldt dyke, a strong fortress, called the Holy Cross, had been constructed, which was under the special command of Mondragon. Besides this, three other forts had been built, at intervals of about a mile, upon the dyke. The one nearest to Mondragon was placed at the Kowenstyn manor-house, and was called Saint James. This was entrusted to Camillo Bourbon del Monte, an Italian officer, who boasted the blood royal of France in his veins, and was disposed on all occasions to vindicate that proud pedigree by his deeds. The next fort was Saint George's, sometimes called the Black Sconce. It had been built by La Motte, but it was now in command of the Spanish officer, Benites. The third was entitled the Fort of the Palisades, because it had been necessary to support it by a stockade-work in the water, there being absolutely not earth enough to hold the structure. It was placed in the charge of Captain Gamboa. These little castles had been created, as it were, out of water and upon water, and under a hot fire from the enemy's forts and fleets, which gave the pioneers no repose.
"'Twas very hard work," said Parma, "our soldiers are so exposed during their labour, the rebels playing upon them perpetually from their musket-proof vessels. They fill the submerged land with their boats, skimming everywhere as they like, while we have none at all. We have been obliged to build these three forts with neither material nor space; making land enough for the foundation by bringing thither bundles of hurdles and of earth. The fatigue and anxiety are incredible. Not a man can sleep at night; not an officer nor soldier but is perpetually mounting guard. But they are animated to their hard work by seeing that I share in it, like one of themselves. We have now got the dyke into good order, so far as to be able to give them a warm reception, whenever they choose to come."
Quite at the farther or land end of the Kowenstyn, was another fort, called the Stabroek, which commanded and raked the whole dyke, and was in the neighbourhood of Mansfeld's head-quarters.
Placed as were these little citadels upon a slender, and—at brief distance—invisible thread of land, with the dark waters rolling around them far and near, they presented an insubstantial dream-like aspect, seeming rather like castles floating between air and ocean than actual fortifications—a deceptive mirage rather than reality. There was nothing imaginary, however, in the work which they were to perform.
A series of attacks, some serious, others fictitious, had been made, from time to time, upon both bridge and dyke; but Alexander was unable to inspire his soldiers with his own watchfulness. Upon the 7th of May a more determined attempt was made upon the Kowenstyn, by the fleet from Lillo. Hohenlo and Colonel Ysselstein conducted the enterprise. The sentinels at the point selected—having recently been so often threatened by an enemy, who most frequently made a rapid retreat, as to have grown weary and indifferent-were surprised, at dawn of day, and put to the sword. "If the truth must be told," said Parma, "the sentries were sound asleep." Five hundred Zeelanders, with a strong party of sappers and miners, fairly established themselves upon the dyke, between St. George's and Fort Palisade. The attack, although spirited at its commencement, was doomed to be unsuccessful. A co-operation, agreed upon by the fleet from Antwerp, failed through a misunderstanding. Sainte Aldegonde had stationed certain members of the munition-chamber in the cathedral tower, with orders to discharge three rockets, when they should perceive a beacon-fire which he should light in Fort Tholouse. The watchmen mistook an accidental camp-fire in the neighbourhood for the preconcerted signal, and sent up the rockets. Hohenlo understanding, accordingly, that the expedition was on the point of starting from Antwerp, hastened to perform his portion of the work, and sailed up from Lillo. He did his duty faithfully and well, and established himself upon the dyke, but found himself alone and without sufficient force to maintain his position. The Antwerp fleet never sailed. It was even whispered that the delinquency was rather intended than accidental; the Antwerpers being supposed desirous to ascertain the result of Hohenlo's attempt before coming forth to share his fate. Such was the opinion expressed by Farnese in his letters to Philip, but it seems probable that he was mistaken. Whatever the cause, however, the fact of the Zeelanders' discomfiture was certain. The St. George battery and that of the Palisade were opened at once upon them, the balls came plunging among the sappers and miners before they had time to throw up many spade-fulls of earth, and the whole party were soon dead or driven from the dyke. The survivors effected their retreat as they best could, leaving four of their ships behind them and three or four hundred men.
"Forty rebels lay dead on the dyke," said Parma, "and one hundred and fifty more, at least, were drowned. The enemy confess a much larger loss than the number I state, but I am not a friend of giving details larger than my ascertained facts; nor do I know how many were killed in the boats."
This enterprise was but a prelude, however, to the great undertaking which had now been thoroughly matured. Upon the 26th May, another and most determined attack was to be made upon the Kowenstyn, by the Antwerpers and Hollanders acting in concert. This time, it was to be hoped, there would be no misconception of signals. "It was a determination," said Parma, "so daring and desperate that there was no substantial reason why we should believe they would carry it out; but they were at last solemnly resolved to die or to effect their purpose."
Two hundred ships in all had been got ready, part of them under Hohenlo and Justinus de Nassau, to sail up from Zeeland; the others to advance from Antwerp under Sainte Aldegonde. Their destination was the Kowenstyn Dyke. Some of the vessels were laden with provisions, others with gabions, hurdles, branches, sacks of sand and of wool, and with other materials for the rapid throwing up of fortifications.
