"It were best for you to yield, Sir Archibald Forbes, without giving us the trouble of making our way across your moat. You have made a stout resistance, and have done enough for honour, and you must see that sooner or later we must win our way in."

"Then I would rather it should be later," Archie replied. "I may have done enough for honour, but it is not for honour that I am fighting, but for Scotland. Your work is but begun yet, I can assure you. We are far from being at the end of our resources yet. It will be time enough to talk about surrendering when you have won the breach and the outer walls."

The knights retired; and as some hours passed without the besiegers seeing any preparation for an assault they judged that the report carried back to camp was not an encouraging one. Large numbers of men were, however, seen leaving the camp, and these toward sunset came back staggering under immense loads of brushwood which they had cut in the forest.

"They intend to fill up the moat," Archie said; "it is their wisest course."

He at once directed his men to make up large trusses of straw, over which he poured considerable quantities of oil. Early the next morning the English drew out of their camp, and advanced in martial array. Each man carried a great faggot, and, covering themselves with these as they came within bowshot, they marched down to the moat. Each in turn threw in his faggot, and when he had done so returned to the camp and brought back another. Rapidly the process of filling up the moat opposite to the breach continued. The besiegers kept up a rain of arrows and darts, and many of the English were killed. But the work was continued without intermission until well nigh across the moat a broad crossway was formed level with the outer bank, but a narrow gap remained to be filled, and the English leaders advanced to the front to prevent the Scots on the breach rushing down to assault those placing the faggots.

Somewhat to the surprise of the English the defenders remained stationary, contenting themselves with hurling great stones at their busy enemy. Suddenly there was a movement. Archie and a party of his best men dashed down the breach, and, climbing on the causeway, for a moment drove the workers and their guards back. They were followed by twenty men carrying great trusses of straw. These were piled against the faggots forming the end of the causeway. Archie and his band leapt back as a torch was applied to the straw. In a moment the hot flames leapt up, causing the knights who had pressed after the retreating Scots to fall back hastily. A shout of triumph rose from the garrison and one of dismay from the besiegers. Saturated with oil, the trusses burnt with fury, and the faggots were soon alight. A fresh wind was blowing, and the flames crept rapidly along the causeway. In a few minutes this was in a blaze from end to end, and in half an hour nothing remained of the great pile save charred ashes and the saturated faggots which had been below the water in the moat, and which now floated upon it.

The besiegers had drawn off when they saw that the flames had gained a fair hold of the causeway. The smoke had scarcely ceased to rise when a great outcry arose from the English camp, and the lookout from the top of the keep perceived a strong force marching toward it. By the bustle and confusion which reigned in the camp Archie doubted not that the newcomers were Scots. The garrison were instantly called to arms. The gates were thrown open, and leaving a small body only to hold the gates, he sallied out at the head of his men and marched toward the English camp. At the approach of the Scottish force the English leaders had marched out with their men to oppose them. Bruce had been able to collect but three hundred and fifty men, and the English, seeing how small was the number advancing against them, prepared to receive them boldly. Scarcely had the combat begun when Archie with his band entered the English camp, which was almost deserted. They at once fired the tents, and then advanced in a solid mass with level spears against the rear of the English. These, dismayed at the destruction of their camp, and at finding themselves attacked both front and rear, lost heart and fell into confusion. Their leaders strove to rally them, and dashed with their men-at-arms against the spearmen, but their efforts to break through were in vain, and their defeat increased the panic of the footmen. Archie's party broke a way through their disordered line and joined the body commanded by the king, and the whole rushed so fiercely upon the English that these broke and fled in all directions, pursued by the triumphant Scots.

"I am but just in time I see, Sir Archie," Bruce said, pointing to the breach in the wall; "a few hours more and methinks that I should have been too late."

"We could have held out longer than that, sire," Archie replied. "We have repulsed an attack this morning and burnt a causeway of faggots upon which they attempted to cross the moat; still, I am truly glad that you have arrived, and thank you with all my heart for coming so speedily to my rescue, for sooner or later the hold must have fallen; the great machines which they brought with them from Stirling proved too strong for the wall."

"And how has the Lady Marjory borne her during the siege?" the king inquired.
