In six days afterwards the Jacobite army arrived at Preston, and from this place, where the Prince halted, he sent the Duke of Perth to Scotland to summon his friends from Perth to join him, in order to renew the attack upon England. The Prince was resolved to retire only until he met that reinforcement, and then to march to London, be the consequence what it would.[253] But this scheme, so dearly cherished by Charles, was impracticable. The Duke of Perth, taking with him an escort of seventy or eighty horse, set out for Kendal. He was assailed as he passed through that place by a mob, which he dispersed by firing on them, and resumed his march; but near Penrith he was attacked by a far more formidable force in a band of militia both horse and foot, greatly superior in numbers to his troops, and was obliged to retire to Kendal. On the fifteenth he rejoined the Prince's army, after this fruitless attempt. The retreat of the Prince's army, managed as it was with consummate skill by Lord George Murray, continued without any division of the forces until they had passed the river Esk. There the army separated; and the Duke of Perth commanding one column of the army took the eastern line to Scotland, while Charles marched to Annan in Dumfrieshire. The siege of Stirling is the next event of note in which we find the Duke of Perth engaged. He here acted again as Lieutenant-General, and commanded the siege. Here, too, the valour and fidelity of two other members of his family were again proved. Lord John Drummond, who had landed in Scotland while the Jacobites were at Derby, with the French brigade, was slightly wounded in the battle of Falkirk. He had the honour of being near the Prince in the centre of the battle with his grenadiers; and it was on his artillery and engineers that the Chevalier chiefly depended for success in reducing Stirling. Lord Strathallan had also assembled his men, and joined the army.
