It was the opinion of his most faithful adherents, absolutely devoted, as before Derby, to a cause the weakness of which they appreciated, and which they were resolved to defend to the very end. After his victory at Falkirk, the prince wished to again undertake the siege of Stirling Castle, without other counsel than that of a French engineer, M. de Mirabelle, and some subordinates. The chiefs were gloomy; they presented a remonstrance to the prince; desertions were becoming every day more numerous in the face of foes who were each day more threatening. "We are humbly of opinion," said the highland chiefs, "that the only means of snatching the army from an imminent peril is to withdraw to the highlands, and we can easily occupy the winter in getting possession of the northern fortresses. {211} We are thus certain of retaining sufficient men to deter the enemy from following us into the mountains at this season of the year. In the spring a new army of ten thousand men will be ready to accompany your Royal Highness where it may seem good to you." On this occasion again the determined will of the men who had risked everything in his cause overcame the young prince's obstinacy. In his rage he dashed his head against the wall. "Good God! have I lived long enough to see this?" he cried. But the siege of Stirling Castle was abandoned, and the retreat toward the mountains began without any order or method.

The Duke of Cumberland pursued the retreating army. On the 2nd of February he had entered Stirling; on the 25th he took up quarters at Aberdeen, being himself irritated and gloomy. "All the inhabitants of the country are Jacobites," he wrote; "gentleness would be quite out of place; there would be no end if I should enumerate the villains and the villainies which abound here." The hour of vengeance was approaching, rendered more cruel by the natural harshness of the conqueror, as well as by the passionate obstinacy of those of the rebels who should become his victims. {212} Already the march of the royal army was marked by gibbets. The duke's advance was for a time hindered by the departure of the Dutch troops. Scarcely had Lord John Drummond set foot in Scotland than he had communicated to the troops of the States-General his commission from Louis XV. As prisoners of war who had capitulated at Tournay and at Dendermonde, the Dutch regiments were pledged not to bear arms against France. They had
