'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 assailants, 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 assigned 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 assaults 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
