However, it is of no great importance to us. I saw you lads just now on the wall; I did not care about ordering you down at the time; but don't go up again except to help to carry down the wounded. Make it a rule, my boys, never to shirk your duty, however great the risk to life may be; but, on the other hand, never risk your lives unless it is your duty to do so. What is gallantry in the one case is foolishness in the other. Although you are but pages, yet it may well be that in such a siege as this you will have many opportunities of showing that you are of good English stock; but while I would have you shrink from no danger when there is a need for you to expose yourselves, I say also that you should in no way run into danger wantonly."

Several times in the course of the afternoon the boys took their turn in going up and helping to bring down wounded men. As the time went on several yawning gaps appeared in the walls. The court-yard was strewn with fragments of masonry, and the pages were ordered to keep under shelter of the wall of the castle unless summoned on duty. Indeed, the court-yard had now become a more dangerous station than the wall itself; for not only did the cannon-shot fly through the breaches, but fragments of bricks, mortar, and rubbish flew along with a force that would have been fatal to anything struck.

Some of the pages were big fellows of seventeen or eighteen years old, who had been serving for some years under Morgan and Williams, and would soon be transferred into the ranks.

"I like not this sort of fighting," one of them said. "It is all very well when it comes to push of pike with the Spaniards, but to remain here like chickens in a coop while they batter away at us is a game for which I have no fancy. What say you, Master Vickars?"

"Well, it is my first experience, Somers, and I cannot say that it is agreeable. I do not know whether I should like hand-to-hand fighting better; but it seems to me at present that it would be certainly more agreeable to be doing something than to be sitting here and listening to the falls of the pieces of masonry and the whistling of the b.a.l.l.s. I don't see that they will be any nearer when they have knocked this place to pieces. They have no boats, and if they had, the guns on the city wall would prevent their using them; besides, when the bridge of boats is removed they could do nothing if they got here."

Towards evening a council was held, all the princ.i.p.al officers being present, and it was decided to evacuate the castle. It could indeed have been held for some days longer, but it was plain it would at length become untenable; the bridge of boats had already been struck in several places, and some of the barges composing it had sunk level with the water. Were it destroyed, the garrison of the castle would be completely cut off, and as no great advantage was to be gained by holding the position, for it was evident that it was upon the other end of the town the main attack was to be made, it was decided to evacuate it under cover of night. As soon as it became dark this decision was carried into effect, and for hours the troops worked steadily, transporting the guns, ammunition, and stores of all kinds across from the castle to the town.

Already communication with their friends outside had almost ceased, for the first operation of the enemy had been to block the approach to Sluys from the sea. Boats had been moored head and stern right across Zwin, and a battery erected upon each sh.o.r.e to protect them; but Captains Hart and Allen twice swam down to communicate with friendly vessels below the obstacle, carrying despatches with them from the governor to the States-General, and from Roger Williams to the English commanders, urging that no time should be lost in a.s.sembling an army to march to the relief of the town.

Both contained a.s.surances that the garrison would defend the place to the last extremity, but pointed out that it was only a question of time, and that the town must fall unless relieved. The Dutch garrison were 800 strong, and had been joined by as many English. Parma had at first marched with but 6000 men against the city, but had very speedily drawn much larger bodies of men towards him, and had, as Roger Williams states in a letter to the queen sent from Sluys at an early period of the siege, four regiments of Walloons, four of Germans, one of Italians, one of Burgundians, fifty-two companies of Spaniards, twenty-four troops of horse, and forty-eight guns. This would give a total of at least 17,000 men, and further reinforcements afterwards arrived.

Against so overwhelming a force as this, it could not be hoped that the garrison, outnumbered by more than ten to one, could long maintain themselves, and the Duke of Parma looked for an easy conquest of the place. By both parties the possession of Sluys was regarded as a matter of importance out of all proportion to the size and population of the town; for at that time it was known in England that the King of Spain was preparing a vast fleet for the invasion of Britain, and Sluys was the nearest point to our sh.o.r.es at which a fleet could gather and the forces of Parma embark to join those coming direct from, Spain. The English, therefore, were determined to maintain the place to the last extremity, and while Parma had considered its capture as an affair of a few days only, the little garrison were determined that for weeks at any rate they would be able to prolong the resistance, feeling sure that before that time could elapse both the States and England, knowing the importance of the struggle, would send forces to their relief.

The view taken as to the uselessness of defending the castle was fully justified, as the Spaniards on the following day removed the guns that they had employed in battering it, to their works facing the western gate, and fire was opened next morning. Under cover of this the Spanish engineers pushed their trenches up to the very edge of the moat, in spite of several desperate sorties by the garrison. The boys had been forbidden by Captain Vere to take their place with the company on the walls.

"In time," he said, "as our force decreases, we shall want every one capable of handling arms to man the breaches, but at present we are not in any extremity; and none save those whom duty compels to be there must come under the fire of the Spaniards, for to do so would be risking life without gain."

They had, however, made friends with the wine merchant whose cellars they had visited, and obtained permission from him to visit the upper storey of his warehouse whenever they chose. From a window here they were enabled to watch all that was taking place, for the warehouse was much higher than the walls. It was not in the direct line of fire of the Spanish batteries, for these were chiefly concentrated against the wall a little to their right. After heavy fighting the Spaniards one night, by means of boats from the Zwin, landed upon the d.y.k.e which divided the moat into two channels, and thus established themselves so close under the ramparts that the guns could not be brought to bear upon them. They proceeded to intrench themselves at once upon the d.y.k.e.

The governor, Arnold Groenvelt, consulted with the English leaders, and decided that the enemy must be driven off this d.y.k.e immediately, or that the safety of the city would be gravely imperilled. They therefore a.s.sembled a force of four hundred men, sallied out of the south gate, where two bastions were erected on the d.y.k.e itself, and then advanced along it to the a.s.sault of the Spaniards. The battle was a desperate one, the English and Dutch were aided by their comrades on the wall, who shot with guns and arquebuses against the Spaniards, while the latter were similarly a.s.sisted by their friends along the outer edge of the moat, and received constant reinforcements by boats from their ships.

The odds were too great for the a.s.sailants, who were forced at last to fall back along the d.y.k.e to the south gate and to re-enter the town. It was already five weeks since the English had arrived to take part in the defence, and the struggle now began upon a great scale--thirty cannon and eight culverins opening fire upon the walls. The heaviest fire was on St. James' day, the 25th of July, when 4000 shots were fired between three in the morning and five in the afternoon. While this tremendous cannonade was going on, the boys could not but admire the calmness shown by the population. Many of the shots, flying over the top of the walls, struck the houses in the city, and the chimneys, tiles, and ma.s.ses of masonry fell in the streets. Nevertheless the people continued their usual avocations. The shops were all open, though the men employed served their customers with breast and back pieces buckled on, and their arms close at hand, so that they could run to the walls at once to take part in their defence did the Spaniards attempt an a.s.sault upon them. The women stood knitting at their doors, Frau Menyn looked as sharply after her maids as ever, and washing and scouring went on without interruption.

"I believe that woman will keep those girls at work after the Spaniards have entered the city, and until they are thundering at the door,"

Lionel said. "Who but a Dutch woman would give a thought to a few particles of dust on her furniture when an enemy was cannonading the town?"

"I think she acts wisely after all, Lionel. The fact that everything goes on as usual here and in other houses takes people's thoughts off the dangers of the position, and prevents anything like panic being felt."

The lads spent the greater part of the day at their look-out, and could see that the wall against which the Spanish fire was directed was fast crumbling. Looking down upon it, it seemed deserted of troops, for it would be needlessly exposing the soldiers to death to place them there while the cannonade continued; but behind the wall, and in the street leading to it, companies of English and Dutch soldiers could be seen seated or lying on the ground.

They were leaning out of the dormer-window in the high roof watching the Spanish soldiers in the batteries working their guns, when, happening to look round, they saw a crossbow protruded from a window of the warehouse to their right, and a moment afterwards the sharp tw.a.n.g of the bow was heard. There was nothing unusual in this; for although firearms were now generally in use the long-bow and the cross-bow had not been entirely abandoned, and there were still archers in the English army, and many still held that the bow was a far better weapon than the arquebus, sending its shafts well nigh as far and with a truer aim.

"If that fellow is noticed," Geoffrey said, "we shall have the Spanish musketeers sending their b.a.l.l.s in this direction. The governor has, I heard Captain Vere say, forbidden shooting from the warehouses, because he does not wish to attract the Spanish fire against them. Of course when the wall yields and the breach has to be defended the warehouses will be held, and as the windows will command the breach they will be great aids to us then, and it would be a great disadvantage to us if the Spaniards now were to throw sh.e.l.ls and fire-b.a.l.l.s into these houses, and so to destroy them before they make their attack. Nor can much good be gained, for at this distance a cross-bow would scarce carry its bolts beyond the moat."

"Most likely the man is using the cross-bow on purpose to avoid attracting the attention of the Spaniards, Geoffrey. At this distance they could not see the cross-bow, while a puff of smoke would be sure to catch their eye."

"There, he has shot again. I did not see the quarrell fall in the moat.

See, one of the Spanish soldiers from that battery is coming forward.

There, he has stooped and picked something up. Hallo! do you see that?

He has just raised his arm; that is a signal, surely."

"It certainly looked like it," Lionel agreed. "It was a sort of half wave of the hand. That is very strange!"

"Very, Lionel; it looks to me very suspicious. It is quite possible that a piece of paper may have been tied round the bolt, and that someone is sending information to the enemy. This ought to be looked to."

"But what are we to do, Geoffrey? Merely seeing a Spanish soldier wave his arm is scarcely reason enough for bringing an accusation against anyone. We are not even sure that he picked up the bolt; and even if he did, the action might have been a sort of mocking wave of the hand at the failure of the shooter to send it as far as the battery."

"It might be, of course, Lionel. No, we have certainly nothing to go upon that would justify our making a report on the subject, but quite enough to induce us to keep a watch on this fellow, whoever he may be.

Let us see, to begin with, if he shoots again."

They waited for an hour, but the head of the cross-bow was not again thrust out of the window.

"He may have ceased shooting for either of two reasons," Geoffrey said.

"If he is a true man, because he sees that his bolts do not carry far enough to be of any use. If he is a traitor, because he has gained his object, and knows that his communication has reached his friends outside. We will go down now and inquire who is the occupier of the next warehouse."

The merchant himself was not below, for as he did business with other towns he had had nothing to do since Sluys was cut off from the surrounded country; but one of his clerks was at work, making out bills and accounts in his office as if the thunder of the guns outside was unheard by him. The boys had often spoken to him as they pa.s.sed in and out.

"Who occupies the warehouse on the right?" Geoffrey asked him carelessly.

"William Arnig," he replied. "He is a leading citizen, and one of the greatest merchants in our trade. His cellars are the most extensive we have, and he does a great trade in times of peace with Bruges, Ghent, Antwerp, and other towns."

"I suppose he is a Protestant like most of the towns-people?" Geoffrey remarked.

"No, he is a Catholic; but he is not one who pushes his opinions strongly, and he is well disposed to the cause, and a captain in one of the city bands. The Catholics and Protestants always dwell quietly together throughout the Low Countries, and would have no animosities against each other were it not for the Spaniards. Formerly, at least, this was the case; but since the persecutions we have Protestant towns and Catholic towns, the one holding to the States cause, the other siding with the Spaniards. Why do you ask?"

"Oh, I hadn't heard the name of your next neighbour, and was wondering who he might be."

The boys had now been nearly two months in Holland, and were beginning to understand the language, which is not difficult to acquire, and differed then even less than now from the dialect spoken in the eastern counties of England, between whom and Holland there had been for many generations much trade and intimate relations.

"What had we better do next, Geoffrey?" Lionel asked as they left the warehouse.

"I think that in the first place, Lionel, we will take our post at the window to-morrow, and keep a close watch all day to see whether this shooting is repeated. If it is, we had better report the matter to Captain Vere, and leave him to decide what should be done. I do not see that we could undertake anything alone, and in any case, you see, it would be a serious matter to lay an accusation against a prominent citizen who is actually a captain of one of the bands."

Upon the following day they took their post again at the window, and after some hours watching saw three bolts fired from the next window.

Watching intently, they saw the two first fall into the moat. They could not see where the other fell; but as there was no splash in the water, they concluded that it had fallen beyond it, and in a minute they saw a soldier again advance from the battery, pick up something at the edge of the water, raise his arm, and retire. That evening when Captain Vere returned from the ramparts they informed him of what they had observed.

"Doubtless it is an act of treachery," he said, "and this merchant is communicating with the enemy. At the same time what you have seen, although convincing evidence to me, is scarce enough for me to denounce him. Doubtless he does not write these letters until he is ready to fire them off, and were he arrested in his house or on his way to the warehouse we might fail to find proofs of his guilt, and naught but ill-feeling would be caused among his friends. No, whatever we do we must do cautiously. Have you thought of any plan by which we might catch him in the act?"

"If two or three men could be introduced into his warehouse, and concealed in the room from which he fires, they might succeed in catching him in the act, Captain Vere; but the room may be an empty one without any place whatever where they could be hidden, and unless they were actually in the room they would be of little good, for he would have time, if he heard footsteps, to thrust any letter he may have written into his mouth, and so destroy it before it could be seized."

"That is so," Captain Vere agreed. "The matter seems a difficult one, and yet it is of the greatest importance to hinder communications with the Spaniards. To-night all the soldiers who can be spared, aided by all the citizens able to use matlock and pick, are to set to work to begin to raise a half-moon round the windmill behind the point they are attacking, so as to have a second line to fall back upon when the wall gives way, which it will do ere long, for it is sorely shaken and battered. It is most important to keep this from the knowledge of the Spaniards. Now, lads, you have shown your keenness by taking notice of what is going on, see if you cannot go further, and hit upon some plan of catching this traitor at his work. If before night we can think of no scheme, I must go to the governor and tell him frankly that we have suspicions of treachery, though we cannot prove them, and ask him, in order to prevent the possibility of our plans being communicated to the enemy, to place some troops in all the warehouses along that line, so that none can shoot therefrom any message to the Spaniards."

Just as Captain Vere finished his supper, the boys came into the room again.

"We have thought of a plan, sir, that might succeed, although it would be somewhat difficult. The dormer-window from which these bolts have been fired lies thirty or forty feet away from that from which we were looking. The roof is so steep that no one could hold a footing upon it for a moment, nor could a plank be placed upon which he could walk. The window is about twelve feet from the top of the roof. We think that one standing on the ledge of our window might climb on to its top, and once there swing a rope with a stout grapnel attached to catch on the ridge of the roof; then two or three men might climb up there and work themselves along, and then lower themselves down with a rope on to the top of the next window. They would need to have ropes fastened round their bodies, for the height is great, and a slip would mean death.

"The one farthest out on the window could lean over when he hears a noise below him, and when he saw the cross-bow thrust from the window, could by a sudden blow knock it from the fellow's hand, when it would slide down the roof and fall into the narrow yard between the warehouse and the walls. Of course some men would be placed there in readiness to seize it, and others at the door of the warehouse to arrest the traitor if he ran down."

"I think the plan is a good one, though somewhat difficult of execution," Captain Vere said. "But this enterprise on the roof would be a difficult one and dangerous, since as you say a slip would mean death."

"Lionel and myself, sir, would undertake that with the aid of two active men to hold the ropes for us. We have both done plenty of bird-nesting in the woods of Hedingham, and are not likely to turn giddy."

"I don't think it is necessary for more than one to get down on to that window," Captain Vere said. "Only one could so place himself as to look down upon the cross-bow. However, you shall divide the honour of the enterprise between you. You, as the eldest and strongest, Geoffrey, shall carry out your plan on the roof, while you, Lionel, shall take post at the door with four men to arrest the traitor when he leaves. I will select two strong and active men to accompany you, Geoffrey, and aid you in your attempt; but mind, before you try to get out of the window and to climb on to its roof, have a strong rope fastened round your body and held by the others; then in case of a slip, they can haul you in again. I will see that the ropes and grapnels are in readiness."

The next morning early Geoffrey proceeded with the two men who had been selected to accompany him to his usual look-out. Both were active, wiry men, and entered fully into the spirit of the undertaking when Geoffrey explained its nature to them. They looked out of the dormer-window at the sharp roof slanting away in front of them and up to the ridge above.
