"I have," was his answer. "Lord Mar and his lady are kept in a square tower which stands in the cleft between the two summits of the rock. It is not only surrounded by embattled walls, which flank the ponderous buttresses of this huge dungeon, but the space on which it stands is bulwarked at each end by a stone curtain of fifteen feet high, guarded by turrets full of armed men. "And yet by that side you suppose we must ascend?" said Wallace. "Certainly; for if you attempt it on the west, we should have to scale the watch-tower cliff, and the ascent could only be gained in file. An auxiliary detachment, to attack in flank, might succeed there; but the passage being so narrow, would be too tedious for the whole party to arrive in time. Should we take the south, we must cut through the whole garrison before we could reach the earl. And on this side, the morass lies too near the foot of the rock to admit an approach without the greatest danger. But on the north, where I descended, by wading through part of the Leven, and climbing from cliff to cliff, I have every hope you may succeed." Edwin recounted the particulars of his progress through the fortress; and by the minuteness of his topographical descriptions, enforced his arguments for the north to be the point assailed. Closing his narrative, he explained to the anxious inquiry of Wallace how he had escaped accident in a leap of so many feet. The wall was covered with ivy; he caught by its branches in his descent, and at last happily fell amongst a thick bed of furze. After this, he clambered down the steep, and fording the Leven (there only knee deep), now appeared before his general, elate in heart, and bright in valor. "The intrepidity of this action," returned Wallace, glowing with admiration at so noble a daring in so young a creature, "merits that every confidence should be placed in the result of your observations. Your safe return is a pledge of our design being approved. And when we go in the strength of Heaven, who can doubt the issue? This night, when the Lord of battles puts that fortress into our hands, before the whole of our little army you shall receive that knighthood you have so richly deserved. Such, my truly dear brother, my noble Edwin, shall be the reward of your virtue and your toil." Wallace would now have sent him to respose himself; but animated by the success of his adventure, and exulting in the honor which was so soon to stamp a sign of this exploit upon him forever, he told his leader that he felt no want of sleep, and would rather take on him the office of arousing the other captains to their stations, the moon, their preconcerted signal, being then approaching its rest.
