He consulted Maitre Georges; but the latter could make no suggestion; his only advice being the erection of a battery at a spot where it was almost self evident that it could be of no utility whatever. Other circumstances combined to render the suspicions D'Aubusson had entertained of the good faith of the renegade almost a certainty. Georges was seized, tried, and put to torture, and under this owned that he had been sent into the town for the purpose of betraying it; and he was, the same day, hung in the great square. His guilt must always be considered as uncertain. There was no proof against him, save his own confession; and a confession extorted by torture is of no value whatever. There are certainly many good grounds for suspicion, but it is possible that Georges really repented his apostacy, and acted in good faith in deserting the standard of Paleologus. He was undoubtedly a man of altogether exceptional ability and acquirements, and even the knights who have written accounts of the siege do justice to the fascination of his manner and the charm of his conversation. D'Aubusson now set to work in another direction to counteract the efforts of the Turks. He erected an immense wooden catapult, which threw huge pieces of rock into the midst of the Turkish works, crushing down the wooden screens erected to hide their approaches, breaking in the covered ways, and causing great loss of life among the besiegers. At the same time galleries were driven below the breach, opening into the ditch, where their exits were concealed by masses of rubbish. Through these strong working parties issued out at night, and carried away up the passages the rocks and other materials that the Turks had, during the day, brought, with immense labour, from a distance to the shoot. The materials so carried away were piled up behind the retrenchment, greatly adding to its thickness and strength. For some days the Turks observed, to their astonishment, that the road they were constructing across the ditch was diminishing instead of increasing in bulk, and at length it became so evident that the garrison were in some way removing the materials, that the pasha determined to deliver the assault before the heap was so far diminished as to become impassable. His former defeats had, however, taught him that success could not be always calculated upon, however good its prospect might appear; and although he had no real hope that the defenders would yield, he sent a formal summons for them to do so. This was refused with disdain, and preparations were at once made for the assault. The pasha promised to his soldiers the sack of the town and all the booty captured, and so assured were they of success that sacks were made to carry off the plunder. Stakes, on which the knights, when taken prisoners, were to be impaled, were prepared and sharpened, and each soldier carried a coil of rope with which to secure his captive.
