Aware that he should now infallibly be discovered, Gilbert started to his feet, and drawing a dagger which he had picked up in the giants’ chamber, stood upon his defence. The movement betrayed him. Though confounded by his appearance, the sentinel nearest him presented his partizan at his breast and commanded him to surrender. Gilbert answered by striking up the man’s arm, and instantly sprang over the battlements.
A loud splash told that he had fallen into the moat. The men held the torch over the side of the turret. But it was too dark to distinguish any object below. Presently, however, a noise was heard in the water that convinced them the fugitive was swimming for the opposite bank. One of the soldiers instantly discharged his caliver in the direction of the sound,—but without effect.
This served as an alarm to the guards posted on the western ramparts, as well as to those on the Middle Tower, both of which commanded this part of the moat, and other shots were immediately fired. A signal was then rapidly passed from tower to tower, and from portal to portal, until it reached the Bulwark-gate, which formed the only entrance to the fortress on the west, and a body of armed men carrying lights instantly sallied forth and hurried towards the side of the moat.
Gilbert, meanwhile, swam for his life. Guided by the torches, which served to discover his enemies rather than to betray him, he effected a secure landing, But before he had climbed the steep bank, he was observed by a soldier, who, making towards him, shouted to his comrades for assistance. In the struggle that ensued, the torch borne by the soldier was extinguished, and bursting from him, Gilbert darted at a swift pace up Tower-hill. His pursuers were close upon him. But, well acquainted with the spot, he contrived to baffle them, by flinging himself beneath the permanent scaffold, then standing upon the brow of the eminence, and thus eluded observation. As soon as his foes had passed, he struck off swiftly to the left, and leaping a low wall, skirted All-hallows Church, and speedily gained Tower-street.
While Gilbert was flying in this direction, his pursuers finding themselves at fault, hastened back, and endeavoured to discover some trace of him. Some mounted the steps of the scaffold to see whether he had taken refuge on its blood-stained planks,—some crept under it,—others examined the posts of the neighbouring gallows,—while a fourth party flew to the postern gate, which defended the southern extremity of the city wall, in the hope that he might have been stopped by the watch. All, however, it is needless to say, were disappointed. And after some time had been fruitlessly expended, the whole party returned to the Tower to report the unsuccessful issue of their expedition.
