key to the whole series of fortifications, and was connected by a curtain with the old church, which was in the heart of the old town. Spinola had assumed command in October, but the winter was already closing in with its usual tempests and floods before there had been time for him to produce much effect. It seemed plain enough to the besieged that the object of the enemy would be to work his way through the Polder, and so gradually round to the Porcupine and the Sand Hill. Precisely in what directions his subterraneous passages might be tending, in what particular spot of the thin crust upon which they all stood an explosion might at any moment be expected, it was of course impossible to know. They were sure that the process of mining was steadily progressing, and Maurice sent orders to countermine under every bulwark, and to secretly isolate every bastion, so that it would be necessary for Spinola to make his way, fort by fort, and inch by inch. Thus they struggled drearily about under ground, friend and foe, often as much bewildered as wanderers in the catacombs. To a dismal winter succeeded a ferocious spring. Both in February and March were westerly storms, such as had not been recorded even on that tempest-swept coast for twenty years, and so much damage was inflicted on the precious Sand Hill and its curtain, that, had the enemy been aware of its plight, it is probable that one determined assault might have put him in possession of the place. But Ostend was in charge of a most watchful governor, Peter van Gieselles, who had succeeded Charles van der Noot at the close of the year 1603. A plain, lantern jawed, Dutch colonel; with close-cropped hair, a long peaked beard, and an eye that looked as if it had never been shut; always dressed in a shabby old jerkin with tarnished flowers upon it, he took command with a stout but heavy heart, saying that the place should never be surrendered by him, but that he should never live to see the close of the siege. He lost no time in repairing the damages of the tempest, being ready to fight the west wind, the North Sea, and Spinola at any moment, singly or conjoined. He rebuilt the curtain of the Sand Hill, added fresh batteries to the Porcupine and Hell's Mouth, and amused and distracted the enemy with almost daily sorties and feints. His soldiers passed their days and nights up to the knees in mud and sludge and sea-water, but they saw that their commander never spared himself, and having a superfluity of food and drink, owing to the watchful care of the States-General, who sent in fleets laden with provisions faster than they could be consumed, they were cheerful and content.
