The battle of Falkirk struck terror into every English heart, and the panic of the Black Monday again spread like a contagion throughout the country. After the retreat from Derby, the higher ranks of society in England, who had betrayed an unwonted degree of alarm, concluded that they had nothing more to fear even from "a band of men so desperately brave who had done so much with such little means." The victory at Falkirk was, therefore, received with redoubled alarm; and at court, during a ball which was held instantly after the event, only two persons appeared with calm and cheerful countenances. These were the King, whose personal courage was undoubted, and General Cope, who rejoiced that Hawley's failure might in some measure excuse his own.[167]

Under these circumstances, and being assured that the panic in Edinburgh equalled that in London, Prince Charles was strongly advised to repair to Edinburgh and to resume the possession of the capital. He hesitated, and the delay proved fatal to his interests. There was no time to be lost;—the conduct of Hawley had inspired universal contempt not only for his abilities, but for his cowardice. "General Hawley," wrote General Wightman to Duncan Forbes, "is much in the same situation as General Cope, and was never seen in the field during the battle; and everything would have gone to wreck in a worse manner than at Preston, if General Huske had not acted with judgment and courage, and appeared everywhere."

Lord George Murray remained at Falkirk with the Clans until apprised, through the secretary Murray, that the Duke of Cumberland was expected at Edinburgh on the twenty-eighth of the month; and that it was Charles's intention to attack him as soon as he arrived at Falkirk. At the first news of the project, Lord George seemed to approve of it; he drew up a plan of the battle, which he submitted to the ardent young Chevalier, who was delighted to think that he was to have to oppose the Duke of Cumberland in person. But this hope was transient; for on the very same evening, a representation, signed at Falkirk, by Lord George Murray and all the commanders of Clans, begging him to retreat, was presented to the disappointed and indignant Charles Edward. The great desertions which were daily taking place since the battle, was made the chief plea of this unexpected address; two thousand men, it was alleged, had gone off since that action, whilst the army of the enemy was reinforced. Some of the battalions were said to be one-third weaker than before the engagement at Falkirk.

The Prince received this address with a dissatisfaction even more apparent than that which he had shown at Derby, when persuaded to retreat. He dashed his head against the wall with violence, exclaiming, "Good God! have I lived to see this?" As the event showed, it had perhaps been wiser to have risked the event of an action at that time, than to have awaited the mournful catastrophe of Culloden. At length, although he never could be brought to approve of the step, Charles gave a reluctant and sorrowful consent to that which all his chieftains called upon him to adopt. The burden of the censure which was afterwards cast upon this decision, was thrown upon the Lieutenant-General. "I was told," writes Lord George, "that I was much blamed for it. I really cannot tell who was the first that spoke of it, but this I am sure, every one of us were unanimously of the same opinion." The siege of Stirling had proved, indeed, wholly unsuccessful; that very morning the battery, although it had been long in preparation, was silenced in a few hours after it began to play. It was therefore determined to abandon it; and it was decided that the time of the army would be more profitably employed in driving Lord Loudon from Inverness, and in taking the forts in the north, than in a rash engagement, or a hopeless siege. The spirit of the enterprise was, indeed, gone; otherwise such a retreat could never have been proposed and entertained. It was, however, fully determined on. The deepest dejection prevailed among the army when it was announced.

The Prince still remained at Bannockburn. On the thirty-first of the month it was determined to have a general review of the troops; the retreat was not to begin until ten o'clock. Early in the morning Charles Edward, still hoping that the desertions were not so numerous as had been represented, and that the "odious retreat" might be prevented, came out to view his troops. There was hardly the appearance of an army to receive him. On hearing the decision of the Prince, the men had risen at day-break and had gone off to the Frews, many of them having arrived by that time at that ford. There was nothing to be done; Lord George Murray, who had now joined the Prince from Falkirk, and who was quartered with some troops in the town of Stirling, was summoned. The Prince marched off with some of the chiefs and the few troops he had with him, and Lord George brought up the rear. A great portion of the artillery was left behind; the heaviest pieces being nailed up and abandoned. The retreat was thus precipitately commenced, and presented a very different aspect to the withdrawal of the Prince's troops from Derby.

Of this disorderly and disreputable march, Lord George Murray knew nothing until it was begun. The very morning on which it took place, the church of St. Ninian's, where the powder was lodged, was blown up. Lord George Murray was in his quarters when he heard the great noise of the explosion, and thought it was a firing from the Castle. "My surprise," he thus writes, "is not to be expressed.[168] I knew no enemy was even come the length of Falkirk; so that, except the garrison of Stirling Castle, nothing could hurt us. I imagined they had sallied, and made the confusion I observed. I shall say no more about this; a particular account of it is wrote. I believe the like of it never was heard of."

The destruction of St. Ninian's tower is attributed by most historians to the awkwardness of the Highlanders, in attempting to destroy their ammunition. "I am apt to think it was an accident," observes Maxwell, "or, at least, the design of some very private person, for there was no warning given to any body to get out of the way. Nine or ten country people, and five of the Jacobite soldiers, perished from the explosion; and the Prince, over whose existence a special Providence appeared to have watched, was within being hurt when the explosion took place."[169]

The Highland army was quartered on the first night of their march at Doune and Dumblain; and assembled the next day at Crieff. Here Charles Edward again reviewed them, and to his surprise found that they had mostly re-assembled, and that scarcely a thousand of the troops were wanting. The young Prince, who had reluctantly consented to the retreat upon the supposition that he had lost one half of his army, reproached Lord George Murray with having advised that step. Many were the censures heaped upon the General for his councils; and it must be acknowledged, that the caution apparent in his character was, in this instance, carried to an extreme. He excused himself on the plea of his opinion having been that of the whole army; but exonerated himself from any participation in the sudden departure, or, as he calls it, "the flight" from Stirling. At the council which was then called, heats and animosities rose to a height which had never before been witnessed, even among the vehement and discordant advisers of the Prince. After many fierce altercations, it was determined that Prince Charles should march to Inverness by the Highland road; and that Lord George Murray, with his horse, and the low country regiments, should proceed along the coast road, by Montrose and Aberdeen to the same place.

During the last few months the Marquis of Tullibardine had been stationary, employing himself in the fruitless endeavour to stimulate the tenantry and the neighbourhood to join the army of Charles Edward. After leaving Bannockburn he remained at Polmaise, a small village in Stirlingshire, until urged by Lord George to repair to Blair Castle, to garrison that place; for which purpose, according to his opinion, a body of fifty men would be sufficient. In his letters to his brother, Lord George recommends a degree of severity towards deserters which was not consonant with the mild temper of Tullibardine: "Those who have gone home without a special licence on furlough, must be exemplarily punished, either in their persons or effects, or in both; for when our all depends, lenity would be folly." After urging the Marquis to send off the men to Blair by dozens, he adds, "If rewards and punishments do not, I know not what will. By the laws of God and man you have both in your power and your person:" thus alluding to the Marquis's position as a chief.
