"I do not say that it is not a good one," Sandy replied cautiously, "or that it is not one that Sir Archie might have carried out if he had been here."

"Very well, Andrew, then that is quite enough. I give you the orders and I am responsible, and if you and Sandy do not choose to obey me, I shall call the men together myself and lead them without you."

As Sandy and Andrew were quite conscious that their lady would be as good as her word, they at once proceeded to carry her orders into effect. The wheels of the portcullis and drawbridge were oiled, as were the bolts and hinges of the gate. The men were formed up in the courtyard, where presently they were joined by Marjory who had put on a light steel cap and a shirt of mail, and who had armed herself with a light sword. The men gathered round her enthusiastically, and would have burst into cheers had she not held up her hand to command silence.

"I will to the wall now," she said, "to watch for the signal. The instant the attack begins and the attention of those in the outwork is called that way, draw up the portcullis noiselessly and open the gate, oil the hinges of the drawbridge and have everything in readiness; then I will join you. Let the drawbridge be lowered swiftly, and as it falls we will rush across. You have, I suppose, told off the men who are to remain behind. Tell them that when the last of us have crossed they are to raise the drawbridge a few feet, so that none can cross it until we return."

Then, accompanied by Macpherson, she ascended the walls. All was quiet in the hostile camp, which was about a quarter of a mile distant, and only the creaking of the wheels of the machines, the orders of those directing them, and the dull crash as the great stones struck the wall, broke the stillness of the night. For half an hour they watched, and then a sudden uproar was heard in the camp. The Scottish war cry pealed out, followed by shouts and yells, and almost instantly flames were seen to mount up.

"My lord is at work," Marjory said, "it is time for us to be doing also." So saying she ran down to the courtyard. Sandy Grahame, Macpherson, and a few picked men took their place around her, then the drawbridge was suddenly run down, and the Scots dashed across it. As Marjory had anticipated, the English in the outwork had gathered on the farther side and were watching the sudden outbreak in the camp. Alarmed at the prospect of an attack, perhaps by the Bruce, in that quarter, they were suddenly startled by the rush of feet across the drawbridge, and before they had time to recover from their surprise the Scots were upon them. The latter were superior in numbers, and the English, already alarmed by the attack upon their camp, offered but a feeble resistance. Many were cut down, but the greater part leapt from the wall and fled towards the camp. The moment resistance ceased the outer gate was thrown open, and at full speed the Scotch made for the machines. The party here had suspended their work and were gazing towards the camp, where the uproar was now great. The wind was blowing briskly and the fire had spread with immense rapidity, and already half the camp was in flames. Suddenly from the bank above the Scots poured down upon them like a torrent. There was scarcely a thought of resistance. Stricken with dismay and astonishment at this unexpected attack, the soldiers working the machines fled hastily, only a few falling beneath the swords of the Scots. The men with axes at once fell upon the machines, cutting the ropes and smashing the wheels and levers which worked them, while those with the faggots piled them round. In less than two minutes the work was done, lighted torches were applied to the faggots, and the flames soon shot up hotly.

The Scots waited but a minute or two to see that the work was thoroughly done and that the flames had got fair hold, and then, keeping in a close body, they retired to the castle. Not a soul was met with by the way, and leaving Andrew Macpherson with fifty men to hold the outwork until Archie should return and decide whether it should be occupied, Marjory, with the rest, re-entered the castle.

She at once ascended to the walls again, where Sandy also posted the men to be in readiness to open fire with their arrows should the English return and endeavour to extinguish the flames round the machines. The sound of fighting had ceased at the camp. By the light of the flames numbers of the English could be seen pulling down the tents which the fire had not yet reached and endeavouring to check the conflagration, while a large body of horse and foot were rapidly advancing toward the castle.

As soon as they came within bowshot range the archers opened fire, and the English leaders, seeing that it was already too late to save the machines, which were by this time completely enveloped in flames, and that men would only be sacrificed to no good purpose, halted the troops. They then moved towards the outwork, but finding this in possession of the Scots, they fell back again to the camp to take council as to the next steps to be adopted. Archie's attack had been crowned with complete success. Apprehending no danger from behind, the English had neglected to place sentries there, and the Scots were already among the tents before their presence was discovered. Numbers of the English were cut down and the tents fired, and as soon as the English recovered from their first surprise and began to form, Archie gave the word for a retreat. This was effected without molestation, for the first thought of the English was to save the camp from total destruction. The reports of the men who escaped from the castle outwork and the outburst of flames around the machines added to the confusion which reigned, and the leaders, who had by the light of the flames ascertained that the assault upon the camp had been made by a small body of the enemy, deemed it of the first importance to move at once to save the machines if it were still possible.

The Scots regained the entrance to the passage without the loss of a single man, and passing through, soon re-entered the castle. Marjory had laid aside her warlike trappings and awaited her husband's return at the inner entrance of the passage.
