The first military effort of the new governor was to endeavour to relieve the city of Middleburg, the capital of the Island of Walcheren, which had long been besieged by the Protestants. Mondragon the governor was sorely pressed by famine, and could hold out but little longer, unless rescue came. The importance of the city was felt by both parties. Requesens himself went to Bergen op Zoom, where seventy-five ships were collected under the command, nominally, of Admiral de Glines, but really under that of Julian Romero, while another fleet of thirty ships was assembled at Antwerp, under D'Avila, and moved down towards Flushing, there to await the arrival of that of Romero. Upon the other hand, the Prince of Orange collected a powerful fleet under the command of Admiral Boisot, and himself paid a visit to the ships, and assembling the officers roused them to enthusiasm by a stirring address.
On the 20th of January the Good Venture again entered the port of Delft; and hearing that a battle was expected in a few days, Captain Martin determined to take part in it. As soon as he had unloaded his cargo he called the crew together and informed them of his determination, but said that as this was no quarrel of theirs, any who chose could remain on shore until his return.
But Englishmen felt that the cause of Holland was their own, and not a single man on board availed himself of this permission. Ned informed the Prince of Orange of his father's intention, and asked leave to accompany him.
"Assuredly you may go if you please," the prince said; "but I fear that, sooner or later, the fortune of war will deprive me of you, and I should miss you much. Moreover, almost every sailor in port is already in one or other of Boisot's ships; and I fear that, with your weak crew, you would have little chance if engaged with one of these Spanish ships full of men."
"We have enough to work our cannon, sir," Ned said; "besides, I think we may be able to beat up some volunteers. There are many English ships in port waiting for cargoes, which come in but slowly, and I doubt not that some of them will gladly strike a blow against the Spaniards."
Ned and Peters accordingly went round among the English vessels, and in the course of two hours had collected a hundred volunteers. In those days every Englishman regarded a Spaniard as a natural enemy. Drake and Hawkins, and other valiant captains, were warring fiercely against them in the Indian seas, and officers and men in the ships in Delft were alike eager to join in the forthcoming struggle against them.
The Good Venture had, flying the Dutch flag, joined Boisot's fleet at Romerswael, a few miles below Bergen, on the 27th of January; and when the Hollanders became aware of the nationality of the vessel which had just joined them, they welcomed them with tremendous cheers. Two days later the fleet of Romero were seen coming down the river in three divisions. When the first of the Spanish ships came near they delivered a broadside, which did considerable execution among the Dutch fleet. There was no time for further cannonading. A few minutes later the fleets met in the narrow channel, and the ships grappling with each other, a hand to hand struggle began.
The fighting was of the most desperate character; no quarter was asked or given on either side, and men fought with fury hand to hand upon decks slippery with blood. But the combat did not last long. The Spaniards had little confidence in themselves on board ship. Their discipline was now of little advantage to them, and the savage fury with which the Zeelanders fought shook their courage. Fifteen ships were speedily captured and 1200 Spaniards slain, and the remainder of the fleet, which, on account of the narrowness of the passage had not been able to come into action, retreated to Bergen.
Romero himself, whose ship had grounded, sprang out of a porthole and swam ashore, and landed at the very feet of the Grand Commander, who had been standing all day upon the dyke in the midst of a pouring rain, only to be a witness of the total defeat of his fleet. Mondragon now capitulated, receiving honourable conditions. The troops were allowed to leave the place with their arms, ammunition, and personal property, and Mondragon engaged himself to procure the release of Sainte Aldegonde and four other prisoners of rank, or to return and give himself up as a prisoner of war.
Requesens, however, neither granted the release of the prisoners, nor permitted Mondragon to return. It was well for these prisoners, that Bossu was in the hands of the prince. Had it not been for this they would have all been put to death.
