"Were you not bound by your vows as a knight of the Order, how would you feel in the matter?"

"I should feel worse," Gervaise said, without hesitation. "I have oftentimes thought that over, and I see that it is good for me I am so bound. It does not decrease my chances, for, as I know, there are no chances; but it renders it more easy for me to know that it is so."

"But why should you say that you have no chances, Tresham?"

"Because it is easy to see that it is so. I am, save for my commandery and prospects in the Order, a penniless young knight, without home or estate, without even a place in my country, and that country not hers. I know that it is not only sinful, but mad, for me to think so frequently of her, but at least I am not mad enough to think that I can either win the heart or aspire to the hand of one who is, you say, so beautiful, and who is, moreover, as I know, the heiress to wide estates."

"'There was a squire of low degree, Loved the king's daughter of Hungarie,'" Caretto sang, with a laugh. "You are not of low degree, but of n.o.ble family, Gervaise. You are not a squire, but a knight, and already a very distinguished one; nor is the young lady, though she be a rich heiress, a king's daughter."

"At any rate, the squire was not vowed to celibacy. No, no, Sir Fabricius, it is a dream, and a pleasant one; but I know perfectly well that it is but a dream, and one that will do me no harm so long as I ever bear in mind that it is so. Many a knight of the Order before me has borne a lady's gage, and carried it valiantly in many a fight, and has been no less true to his vows for doing so."

"Upon the contrary, he has been all the better a knight, Gervaise; it is always good for a knight, whether he belongs to the Order or not, to prize one woman above all others, and to try to make himself worthy of his ideal. As to the vow of celibacy, you know that ere now knights have been absolved from their vows, and methinks that, after the service you have rendered to Italy by ridding the sea of those corsairs, his Holiness would make no difficulty in granting any request that you might make him in that or any other direction. I don't know whether you are aware that, after you sailed from here, letters came from Rome as well as from Pisa, Florence, and Naples, expressive of the grat.i.tude felt for the services that you had rendered, and of their admiration for the splendid exploit that you had performed."

"No; the grand master has had his hands so full of other matters that doubtless an affair so old escaped his memory. Indeed, he may have forgotten that I sailed before the letters arrived."

"Do not forget to jog his memory on the subject, for I can tell you that the letters did not come alone, but were each accompanied by presents worthy of the service you rendered. But as to the vows?"

"As to the vows, I feel as I said just now, that I would not free myself of them if I could, for, being bound by them, I can the more easily and pleasantly enjoy my dream. Besides, what should I do if I left the Order without home, country, or means, and with naught to do but to sell my sword to some warlike monarch? Besides, Caretto, I love the Order, and deem it the highest privilege to fight against the Moslems, and to uphold the banner of the Cross."

"As to that, you could, like De Monteuil and many other knights here, always come out to aid the Order in time of need. As to the vows, I am not foolish enough to suppose that you would ask to be relieved from them, until you had a.s.sured yourself that Claudia was also desirous that you should be free."

"It is absurd," Gervaise said, almost impatiently. "Do not let us talk any more about it, Caretto, or it will end by turning my head and making me presumptuous enough to imagine that the Lady Claudia, who only saw me for three or four days, and that while she was still but a girl, has been thinking of me seriously since."

"I do not know Claudia's thoughts," Caretto remarked drily, "but I do know that last year she refused to listen to at least a score of excellent offers for her hand, including one from a son of the doge himself, and that without any reasonable cause a.s.signed by her, to the great wonderment of all, seeing that she does not appear to have any leaning whatever towards a life in a nunnery. At any rate, if at some future time you should pluck up heart of grace to tell her you love her, and she refuses you, you will at least have the consolation of knowing that you are not the only one, by a long way, whose suit has been rejected. And now as to our affairs here. Methinks that tomorrow that battery will open fire upon us. It seems completed."

"Yes, I think they are nearly ready," Gervaise said, turning his mind resolutely from the subject they had been discussing. "From the palace wall I saw, before I came down here, large numbers of men rolling huge stones down towards the church. Our guns were firing steadily; but could they load them ten times as fast as they do, they would hardly be able to stop the work, so numerous are those engaged upon it."

"Yes we shall soon learn something of the quality of their artillery.

The tower is strong enough to resist ordinary guns, but it will soon crumble under the blows of such enormous missiles. Never have I seen or heard in Europe of cannon of such size; but indeed, in this matter the Turks are far ahead of us, and have, ever since cannon were first cast, made them of much larger size than we in Europe have done. However, there is one comfort; they may destroy this fort, but they have still to cross the water, and this under the fire of the guns on the palace walls; when they once land, their great battery must cease firing, and we shall be able to meet them on equal terms in the breach. Fight as hard as they may, I think we can hold our own, especially as reinforcements can come down to us more quickly than they can be brought across the water."

The next morning, at daybreak, the deep boom of a gun announced to the city that the great battering cannon had begun their work. In the fort the sleeping knights sprang to their feet at the concussion that seemed to shake it to its centre. They would have rushed to the walls, but Caretto at once issued orders that no one should show himself on the battlements unless under special orders.

"There is nothing whatever to be done until the Turks have breached the wall, and are ready to advance to attack us. Every sword will be needed when that hour comes, and each man owes it to the Order to run no useless risk, until the hour when he is required to do his share of the fighting."

The time required to reload the great cannon was considerable, but at regular intervals they hurled their heavy missiles against the wall, the distance being so short that every ball struck it. After some twenty shots had been fired, Caretto, accompanied by Gervaise, went out by a small gate on the eastern side of the tower, and made their way round by the foot of the wall to see what effect the shots had produced on the solid masonry.

Caretto shook his head.

"It is as I feared," he said. "No stones ever quarried by man could long resist such tremendous blows. In some places, you see, the stones are starred and cracked, in others the shock seems to have pulverised the spot where it struck; but, worse, still, the whole face of the wall is shaken. There are cracks between the stones, and some of these are partly bulged out and partly driven in. It may take some time before a breach is effected, but sooner or later the wall will surely be demolished."

"I will go up and make my report to the grand master."

"Do so, Gervaise. I almost wonder that he has not himself come down to see how the wall is resisting."

Gervaise, on reaching the palace, heard that D'Aubusson was at present engaged in examining no less a person than Maitre Georges, the right hand of Paleologus, who had soon after daybreak presented himself before the wall on the other side of the town, declaring that he had left the Turkish service, and craving to be admitted. News had been sent at once to D'Aubusson, who despatched two of the senior knights, with orders to admit him and receive him with all honour. This had been done, and the grand master, with some of his council, were now closeted with the newcomer. Several of the knights were gathered in the courtyard, discussing the event. There was no question that if the renegade came in good faith, his defection would be a serious blow to the a.s.sailants, and that his well known skill and experience would greatly benefit the defenders.

"For my part," Sir John Boswell, who formed one of the detachment which the English langue, as well as all the others, contributed to form the garrison of the palace said, "I would have hung the fellow up by the neck over the gateway, and he should never have set foot within the walls. Think you that a man who has denied his faith and taken service with his enemies is to be trusted, whatever oaths he may take?"

"You must remember, Boswell," another said, "that hitherto Georges has not fought against Christians, but has served Mahomet in his wars with other infidels. I am not saying a word in defence of his having become a renegade; yet even a renegade may have some sort of heart, and now that he has been called upon to fight against Christians he may well have repented of his faults, and determined to sacrifice his position and prospects rather than aid in the attack on the city."

"We shall see. As for me, I regard a renegade as the most contemptible of wretches, and have no belief that they have either a heart or conscience."

When Maitre Georges came out from the palace, laughing and talking with the two knights who had entered with him, it was evident that he was well pleased with his reception by the grand master, who had a.s.signed to him a suite of apartments in the guest house. In reality, however, D'Aubusson had no doubt that his object was a treacherous one, and that, like Demetrius, who had come under the pretence of bringing about a truce, his object was to find out the weak points and to supply the Turks with information. Georges had, in his conversation with him, laid great stress on the strength of the Turkish army, the excellent quality of the troops, and the enormous battering train that had been prepared.

But every word he spoke but added to the grand master's suspicions; for if the man considered that the capture of the city was morally certain, it would be simply throwing away his life to enter it as a deserter.

The grand master was, however, too politic to betray any doubt of Georges' sincerity. Were he treated as a traitor, Paleologus might find another agent to do the work. It was, therefore, better to feign a belief in his story, to obtain all the information possible from him, and at the same time to prevent his gaining any knowledge of affairs that would be of the slightest use to the Turks. Instructions were therefore given to the two knights that, while Georges was to be treated with all courtesy, he was to be strictly watched, though in such a manner that he should be in ignorance of it, and that, whenever he turned his steps in the direction of those parts of the defences where fresh works had been recently added and preparations made of which it was desirable the Turks should be kept in ignorance, he was to be met, as if by accident, by one of the knights told off for the purpose, and his steps diverted in another direction.

Georges soon made himself popular among many of the knights, who had no suspicions of his real character. He was a man of exceptional figure, tall, strong, splendidly proportioned, with a handsome face and gallant bearing. He was extremely well informed on all subjects, had travelled widely, had seen many adventures, was full of anecdote, and among the younger knights, therefore, he was soon regarded as a charming companion. His very popularity among them aided D'Aubusson's plans, as Georges was generally the centre of a group of listeners, and so had but few opportunities of getting away quietly to obtain the information he sought. Gervaise delivered his report to the grand master.

"I am free now," D'Aubusson said, "and will accompany you to St.

Nicholas. I have been detained by the coming of this man Georges. He is a clever knave, and, I doubt not, has come as a spy. However, I have taken measures that he shall learn nothing that can harm us. No lives have been lost at the tower, I hope?"

"No, sir; Caretto has forbidden any to show themselves on the walls."

"He has done well. This is no time for rash exposure, and where there is naught to be gained, it is a grave fault to run risks."

On arriving at the end of the mole, D'Aubusson, accompanied by Caretto, made an investigation of the effect of the Turks' fire.

"'Tis worse than I expected," he said. "When we laid out our fortifications the thought that such guns as these would be used against them never entered our minds. Against ordinary artillery the walls would stand a long battering; but it is clear that we shall have to depend more upon our swords than upon our walls for our defence. Fortunately, although the Turks have indeed chosen the spot where our walls are most open to the a.s.saults of their battery, they have to cross the water to attack the breach when it is made, and will have to fight under heavy disadvantage."

"Tresham was last night saying to me, that it seemed to him it would not be a difficult matter for one who spoke Turkish well, to issue at night on the other side of the town, and to make his way round to the battery, disguised of course as a Turkish soldier, and then, mixing with the artillery men, to drive a spike into one of the touch holes. He said that he would gladly volunteer for the task."

D'Aubusson shook his head decidedly. "It would be too dangerous; and even were a spike driven in, the Turks would have no great difficulty in extracting it, for the tubes are so big that a man might crawl in and drive the spike up from the inside. Moreover, could one or more of the guns be disabled permanently, others would be brought down and set in their place, so that nothing would be gained but a very short delay, which would be of no advantage to us, and certainly would in no way justify the risking of the life of so distinguished a young knight."

The bombardment of St. Nicholas continued for some days. A breach was fast forming in the wall, and a slope composed of the fallen rubbish extended from the front of the breach to the water's edge. The grand master was frequently on the spot, and as this was at present the sole object of attack, the garrison was strengthened by as many knights as could be sheltered within its walls. At night the shattered masonry that had fallen inside was carried out, and with it a new work thrown up across the mole, to strengthen the defence on that side, should the enemy land between the town and the fort. Small batteries were planted wherever they could sweep the approaches to the breach, and planks studded with nails were sunk in the shallow water of the harbour, to impede the progress of those who might attempt to swim or wade across.

For the time, therefore, the functions of Gervaise were in abeyance, and he laboured with the rest of the garrison at the defences.

At daybreak on the 9th of June, a great number of vessels and boats, crowded with soldiers, bore down on St. Nicholas. As they approached, every gun on the fortifications that could be brought to bear upon them opened fire; but in a dense ma.s.s they advanced. Some made their way to the rocks and landed the soldiers there; others got alongside the mole; but the majority grounded in the shallow water of the harbour, and the troops, leaping out, waded to the foot of the breach. On its crest D'Aubusson himself had taken up his station. Beside him stood Caretto, and around them the most distinguished knights of the Order. With wild shouts the Turks rushed up the breach, and swarmed thickly up the ruined masonry until, at its summit, they encountered the steel clad line of the defenders. For hours the terrible struggle continued. As fast as the head of the Turkish column broke and melted away against the obstacle they tried in vain to penetrate, fresh reinforcements took the place of those who had fallen, and in point of valour and devotion the Moslem showed himself a worthy antagonist of the Christian. It was not only at the breach that the conflict raged. At other points the Turks, well provided with ladders, fixed them against the walls, and desperately strove to obtain a footing there. From the breach clouds of dust rose from under the feet of the combatants, mingling with the smoke of the cannon on the ramparts, the fort, and Turkish ships, and at times entirely hid from the sight of the anxious spectators on the walls of the town and fortress, and of the still more numerous throng of Turks on St. Stephen's Hill, the terrible struggle that continued without a moment's intermission.

The combatants now fought in comparative silence. The knights, exhausted and worn out by their long efforts beneath the blazing sun, still showed an unbroken front; but it was only occasionally that the battle cry of the Order rose in the air, as a fresh body of a.s.sailants climbed up the corpse strewn breach. The yell of the Moslems rose less frequently; they sacrificed their lives as freely and devotedly as those who led the first onset had done; but as the hours wore on, the a.s.surance of victory died out, and a doubt as to whether it was possible to break through the line of their terrible foes gained ground. D'Aubusson himself, although, in spite of the remonstrances of the knights, always in the thickest of the fray, was yet ever watchful, and quickly perceived where the defenders were hotly pressed, and where support was most needed.

Gervaise fought by his side, so that, when necessary, he could carry his orders to a little body of knights, drawn up in reserve, and despatch them to any point where aid was needed. The cannon still continued their fire on both sides. A fragment of one of the stone b.a.l.l.s from a basilisk struck off D'Aubusson's helmet. He selected another from among the fallen knights, and resumed his place in the line. Still the contest showed no signs of terminating. The Turkish galleys ever brought up reinforcements, while the defenders grew fewer, and more exhausted.

During a momentary pause, while a fresh body of Turks were landing, Gervaise said to the grand master,

"If you will give me leave, sir, I will go out at the watergate, swim up the inner harbour, and in a very short time turn a few of the craft lying there into fire ships, and tow them out with a couple of galleys.

At any rate, we can fire all these craft that have grounded, and create a panic among the others."

"Well thought of, Gervaise! I will write an order on one of my tablets.

Do you take my place for a minute." Withdrawing behind the line, the grand master sat down on a fragment of stone, and, drawing a tablet from a pouch in his girdle, he wrote on it, "In all things carry out the instructions of Sir Gervaise Tresham: he is acting by my orders and authority, and has full power in all respects."

He handed the slip of parchment to Gervaise, who hurried to the water gate in the inner harbour, threw off his helmet and armour, issued out at the gate, and plunged into the sea. He swam out some distance, in order to avoid the missiles of the Turks, who were trying to scale the wall from the mole, and then directed his course to St. Michael's, which guarded the inner entrance to the fort. He had fastened the parchment in his hair, and as some of the garrison of the tower, noticing his approach, came down to a.s.sist him, he handed it to them and was at once taken to the commander of St. Michael, answering as he went the anxious questions as to how matters stood at the breach.

"Aid is sorely needed. The Turks have gained no foot of ground as yet, but many of the knights are killed and most of the others utterly exhausted with heat and labour. Unless aid reaches them speedily, the tower, with all its defenders, will be lost."

The instant the commander knew what was required, he bade six of the knights embark with Gervaise in a boat moored behind the tower, and row up the harbour to the spot where the shipping was all ma.s.sed together, protected by the high ground of the fortress from the Turkish fire.

Gervaise waved his hand, as he neared the end of the harbour, to the officer on the walls, and while the six knights who were with him ran off to tell the master of the galleys to prepare two of them to leave the port instantly, Gervaise explained to the officer in charge of the wall at that point the plan that he was charged to carry out, and asked for twenty knights to a.s.sist him.

"It will leave us very weak along here," the officer said. "Then let me have ten, and send for another ten from other parts of the wall. Here is the grand master's order, giving me full power and authority, and it is all important that no single moment shall be wasted."
