This was Philip the Prudent's system for conquering the world, and men looked upon him as the consummation of kingcraft.
On the 3rd July Maurice ordered his whole force to be in readiness for the assault. The mines were then sprung.
The bastion of the east gate was blown to ruins. The mine under the Gast-Huys bulwark, burst outwardly, and buried alive many Hollanders standing ready for the assault. At this untoward accident Maurice hesitated to give the signal for storming the breach, but the panic within the town was so evident that Lewis William lost no time in seizing the overthrown eastern bulwark, from the ruins of which he looked over the whole city. The other broken bastion was likewise easily mastered, and the besieged, seeing the storm about to burst upon them with irresistible fury, sent a trumpet. Meantime Maurice, inspecting the effects of the explosion and preparing for the assault, had been shot through the left cheek. The wound was not dangerous, and the prince extracted the bullet with his own hand, but the change of half an inch would have made it fatal. He was not incapacitated—after his wound had been dressed, amidst the remonstrances of his friends for his temerity-from listening to the propositions of the city. They were refused, for the prince was sure of having his town on his own terms.
Next day he permitted the garrison to depart; the officers and soldiers promising not to serve the King of Spain on the Netherland side of the Rhine for six months. They were to take their baggage, but to leave arms, flags, munitions, and provisions. Both Maurice and Lewis William were for insisting on sterner conditions, but the States' deputies and members of the council who were present, as usual, in camp urged the building of the golden bridge. After all, a fortified city, the second in importance after Groningen of all those regions, was the real prize contended for. The garrison was meagre and much reduced during the siege. The fortifications, of masonry and earthwork combined, were nearly as strong as ever. Saint Barbara had done them but little damage, but the town itself was in a sorry plight. Churches and houses were nearly all shot to pieces, and the inhabitants had long been dwelling in the cellars. Two hundred of the garrison remained, severely wounded, in the town; three hundred and fifty had been killed, among others the young cousin of the Nassaus, Count Lewis van den Berg. The remainder of the royalists marched out, and were treated with courtesy by Maurice, who gave them an escort, permitting the soldiers to retain their side-arms, and furnishing horses to the governor.
In the besieging army five or six hundred had been killed and many wounded, but not in numbers bearing the same proportion to the slain as in modern battles.
The siege had lasted forty-four days. When it was over, and men came out from the town to examine at leisure the prince's camp and his field of operations, they were astounded at the amount of labor performed in so short a time. The oldest campaigners confessed that they never before had understood what a siege really was, and they began to conceive a higher respect for the art of the engineer than they had ever done before. "Even those who were wont to rail at science and labour," said one who was present in the camp of Maurice, "declared that the siege would have been a far more arduous undertaking had it not been for those two engineers, Joost Matthes of Alost, and Jacob Kemp of Gorcum. It is high time to take from soldiers the false notion that it is shameful to work with the spade; an error which was long prevalent among the Netherlanders, and still prevails among the French, to the great detriment of the king's affairs, as may be seen in his sieges."
Certainly the result of Henry's recent campaign before Rouen had proved sufficiently how much better it would have been for him had there been some Dutch Joosts and Jacobs with their picks and shovels in his army at that critical period. They might perhaps have baffled Parma as they had done Verdugo.
Without letting the grass grow under his feet, Maurice now led his army from Steenwyck to Zwol and arrived on the 26th July before Coeworden.
This place, very strong by art and still stronger by-nature, was the other key to all north Netherland—Friesland, Groningen, and Drenthe. Should it fall into the hands of the republic it would be impossible for the Spaniards to retain much longer the rich and important capital of all that country, the city of Groningen. Coeworden lay between two vast morasses, one of which—the Bourtange swamp—extended some thirty miles to the bay of the Dollart; while the other spread nearly as far in a westerly direction to the Zuyder Zee. Thus these two great marshes were a frame—an almost impassable barrier—by which the northern third of the whole territory of the republic was encircled and defended. Throughout this great morass there was not a hand-breadth of solid ground—not a resting-place for a human foot, save the road which led through Coeworden. This passage lay upon a natural deposit of hard, dry sand, interposed as if by a caprice of nature between the two swamps; and was about half a mile in width.
The town itself was well fortified, and Verdugo had been recently strengthening the position with additional earthworks. A thousand veterans formed the garrison under command of another Van den Berg, the Count Frederic. It was the fate of these sister's-children of the great founder of the republic to serve the cause of foreign despotism with remarkable tenacity against their own countrymen, and against their nearest blood relations. On many conspicuous occasions they were almost as useful to Spain and the Inquisition as the son and nearly all the other kinsmen of William the Silent had rendered themselves to the cause of Holland and of freedom.
