The Duke of Perth won many of those who were enemies to Charles Edward, over to his cause, by the humanity and civility with which he treated the conquered citizens, over whom he had the chief command until Charles arrived. But even the important advantage thus gained could not still the animosities which had been kindled in the breasts of those who ought to have laid aside all private considerations for the good of their common undertaking. Hitherto Lord George Murray and the Duke of Perth had had separate commands, and had not interfered with each other until the siege of Carlisle. Here the Duke had acted as the chief in command; he had directed the attack, signed the capitulation, and given orders in the town until the Prince arrived. This was a precedent for the whole campaign, and it ill-suited the fiery temper of Lord George Murray to brook it tamely. There was, indeed, much to be said in favour of Lord George's alleged wrongs, in this preference of one so young and inexperienced as the Duke of Perth. In the first place, Lord George was an older Lieutenant-General than his rival; nor could it be agreeable to his Lordship to serve under a man so much his inferior in age and experience. "Lord George," observes Mr. Maxwell, "thought himself the fittest man to be at the head of the army; nor was he the only person that thought so. Had it been left to the gentlemen of the army to choose a general, Lord George would have carried it by vast odds against the Duke of Perth." But there was still another pretext, which was insisted upon as a reason less offensive to the Duke of Perth, whose gentle and noble qualities had much endeared him even to those who did not wish to see him chief in command; this was his religious persuasion. It was argued that, at that time in England, Roman Catholics were excluded from all employments, civil and military, by laws anterior to the Revolution; it was contended that these laws, whether just or not, ought to be complied with until they were repealed; and that a defiance of these laws would confirm all that had been heard of old from the press and from the pulpit, of the Prince's designs to subvert both Church and State: neither could it be alleged in excuse for the young Prince, that a superiority of genius or of experience had won this distinction, in opposition to custom, for the Duke of Perth.

Whilst these murmurs distracted the camp, immediately after the surrender of Carlisle, Lord George Murray resigned his commission of Lieutenant-General, and informed the Prince that thenceforth he would serve as a volunteer. Upon this step, Mr. Maxwell, who seems to have known intimately the merits of the case, makes the following temperate and beautiful reflection.[246] "It would be rash in me to pretend to determine whether ambition, or zeal for the Prince's service, determined Lord George to take this step; or, if both had a share in it, which was predominant: it belongs to the Searcher of hearts to judge of an action which might have proceeded from very different motives."

Under these circumstances, violent discussions took place in the army; and the result was, the wise resolution on the part of a certain officer, not improbably Mr. Maxwell himself, to represent the consequences of these altercations to the Duke of Perth. The undertaking was one of delicacy and difficulty; but the individual who undertook it had not miscalculated the true gentlemanly humility, the real dignity and disinterestedness, of the gallant man to whom he addressed himself. The narrative goes on as follows:

"A gentleman who had been witness to such conversation, and dreaded nothing so much as dissension in a cause which could never succeed but by unanimity, resolved to speak to the Duke of Perth upon this ungrateful subject. He had observed that those that were loudest in their complaints were least inclined to give themselves any trouble in finding out a remedy."

"The Duke, who at this time was happy, but not elevated, upon his success, reasoned very coolly on the matter. He could never be convinced that it was unreasonable that he should have the principal command; but when it was represented to him, that since that opinion prevailed, whether well or ill founded, the Prince's affairs might equally suffer, he took his resolution in a moment; said he never had anything in view but the Prince's interest, and would cheerfully sacrifice everything to it. And he was as good as his word; for he took the first opportunity of acquainting the Prince with the complaints that were against him, insisted upon being allowed to give up his command, and to serve henceforth at the head of his regiment."

After his resignation, the Duke of Perth sank gracefully into the duties of the post assigned to him. But his ardour in the cause was unsubdued; and he was frequently known, during the march from Carlisle to Derby, to ride down three horses a day when information of the enemy was to be procured.

The short sojourn of the Prince at Derby, and the inglorious retreat, have been detailed by the various biographers and historians of that period; but, amongst the various accounts which have been given, that which is contained in a letter from Derby has not hitherto been presented to the reader, except in a collection rarely to be met with, and now but little known.[247]

On Wednesday, the 4th of December (1745), two of the insurgents entered the town, inquired for the magistrates, and demanded billets for nine thousand men, and more. A short time afterwards the vanguard broke into the town, consisting of about thirty men, clothed in blue faced with gold, and scarlet waistcoats with gold lace; and, being "likely men," they made a good appearance. They were drawn up in the market-place, and remained there two hours; at the same time the bells were rung, and bonfires were lighted, in order to do away with the impression that the Chevalier's vanguard had been received disrespectfully. About three o'clock Lord Elcho, on horseback, arrived at the head of the Life-guards, about one hundred and fifty men, the flower of the army, who rode gallantly into the town, dressed like the vanguard, making a very fine display. The Guards were followed by the main body of the army, who marched in tolerable order, two or three abreast, with eight standards, mostly having white flags and a red cross; the bag-pipers playing as they entered. Whilst they were in the market-place, they caused the Chevalier to be proclaimed King, and then asked for the magistrates. These functionaries appeared without their gowns of office, having cautiously sent them out of the town; a circumstance which was with some difficulty excused by the insurgents.

In the dusk of the evening Charles Edward arrived: he walked on foot, attended by many of his men, who followed him to Exeter House, where the Prince remained until his retreat northwards. Here he had guards placed all round the house, and here he maintained the semblance of a Court, in the very heart of that country which he so longed to enter.

The temporary abode of Charles Edward still remains in perfect repair, and much in the same state, with the exception of change of furniture, as when he held levees there. Exeter House at that time belonged to Brownlow, Earl of Exeter, whose connexion with the town of Derby was owing to his marriage with a lady of that city. The house stands back from Full Street, and is situated within a small triangular court. An air of repose, notwithstanding the noise of a busy and important town, characterizes this interesting dwelling. It is devoid of pretension; its gables and chimneys proclaim the Elizabethan period. A wide staircase, rising from a small hall, leads to a square, oak-panelled drawing-room, the presence-chamber in the days of the ill-fated Charles. On either side are chambers, retaining, as far as the walls are concerned, much of the character of former days, but furnished recently. One of these served the Prince as a sleeping-room; the rest were occupied by his officers of state, and by such of his retinue as could be accommodated in a house of moderate size. The tenement contains many small rooms and closets, well adapted, had there been need, for concealment and escape.
