Ronald was introduced to him as soon as he joined at Perth, and finding that young Leslie had had some military experience, Lord George at once appointed him one of his aides de camp, and soon took a warm liking to the active and energetic young officer, whose whole soul was in his work, and who cared nothing for the courtly gatherings around the person of the prince.
Malcolm rode as Ronald's orderly, and during the few days of their stay in Perth, Ronald was at work from morning till night riding through the country with messages from Lord George, and in the intervals of such duty in trying to inculcate some idea of discipline into the wild Highland levies. At this time Charles was using all his efforts to persuade Lord Lovat, one of the most powerful of the northern noblemen, to join him, offering him his patent as Duke of Fraser and the lord lieutenancy of the northern counties.
Lovat, however, an utterly unscrupulous man, refused openly to join, although he sent repeatedly assurances of his devotion. Throughout the struggle he continued to act a double part, trying to keep friends with both parties, but declaring for the prince at the moment when his fortunes were at their highest. The result was that while he afforded the prince but little real assistance, his conduct cost him his head.
Sir John Cope, finding that his march to Inverness had failed to draw the prince after him, and had left the Lowlands and the capital open to the insurgents, directed his march to Aberdeen, and sent to Edinburgh for transports to bring down his army to cover that city. But Prince Charles determined to forestall him, and on the 11th of September commenced his march south. The age and infirmities of the Marquis of Tullibardine prevented his accompanying Prince Charles during active operations.
It was impossible for the army to march direct against Edinburgh, as the magistrates of that town had taken the precaution to withdraw every ship and boat from the northern side of the Forth, and the prince was consequently obliged to make a detour and to cross the river at the fords eight miles above Stirling, and then marching rapidly towards Edinburgh, arrived on the evening of the 16th within three miles of that town.
So long as the coming of the prince was doubtful the citizens of Edinburgh had declared their willingness to defend the town to the last. Volunteer regiments had been formed and guns placed on the walls; but when the volunteers were ordered to march out with Hamilton's regiment of dragoons, to oppose the advance of the insurgents, the men quitted their ranks and stole away to their houses, leaving the dragoons to march out alone. The latter, however, showed no greater courage than that of their citizen allies, when on the following day they came in contact with a party of mounted gentlemen from the prince's army, who fired their pistols at their pickets. These rode off in haste, their panic was communicated to the main body, whose officers in vain endeavoured to check them, and the whole regiment galloped away in wild confusion, and passing close under the walls of Edinburgh continued their flight, without halting, to Preston. There they halted for the night; but one of the troopers happening in the dark to fall into a disused well, his shouts for assistance caused an alarm that they were attacked, and mounting their horses the regiment continued their flight to Dunbar, where they joined General Cope's army, which had just landed there.
This disgraceful panic added to the terror of the citizens of Edinburgh, and when, late in the afternoon, a summons to surrender came in from Prince Charles, the council could arrive at no decision, but sent a deputation to the prince asking for delay, hoping thereby that Cope's army would arrive in time to save them. But the prince was also well aware of the importance of time, and that night he sent forward Lochiel with five hundred Camerons to lie in ambush near the Netherbow Gate. They took with them a barrel of powder to blow it in if necessary; but in the morning the gate was opened to admit a carriage, and the Highlanders at once rushed in and overpowered the guard, and sending parties through the streets they secured these also without disturbance or bloodshed, and when the citizens awoke in the morning they found, to their surprise, that Prince Charles was master of the city.
The Jacobite portion of the population turned out with delight to greet the prince, while the rest thought it politic to imitate their enthusiasm. The Highlanders behaved with perfect order and discipline, and although the town had, as it were, been taken by storm, no single article of property was touched. An hour later Prince Charles, at the head of his troops, entered the royal palace of Holyrod, being met by a crowd of enthusiastic supporters from the city, who received him with royal shouts and tears of joy.
In the evening a grand ball was held in the palace, in spite of the fact that it was within range of the guns of Edinburgh Castle, which still held out. But one day was spent in Edinburgh. This was occupied in serving out about a thousand muskets found in the magazines to the Highlanders, and in obtaining tents, shoes, and cooking vessels, which the town was ordered to supply. They were joined during the day by many gentlemen, and on the night of the 19th the army, two thousand five hundred strong, of whom only fifty were mounted, moved out to the village of Duddingston. There the prince that evening called a council of war, and proposed to march next morning to meet the enemy halfway, and declared that he would himself lead his troops and charge in the first ranks.
The chiefs, however, exclaimed against this, urging that if any accident happened to him ruin must fall upon the whole, whether they gained or lost the battle; and upon the prince persisting they declared that they would return home and make the best terms they could for themselves. He was therefore obliged to give way, declaring, however, that he would lead the second line. The next morning the army commenced its march. They had with them only one cannon, so old that it was quite useless, and it was only taken forward as an encouragement to the Highlanders, who had the greatest respect for artillery.
Sir John Cope, who had received intelligence of all that had happened at Edinburgh, had also moved forward on the 19th, and on the 20th the two armies came in sight of each other. The Highlanders, after passing the bridge of Musselburgh, left the road, and turning to the right took up their position on the brow of Carberry Hill, and there waited the attack. The English forces were marching forward with high spirit, and believed that the Highlanders would not even wait their assault. Cope had with him two thousand two hundred men, including the six hundred runaway dragoons. The numbers, therefore, were nearly equal; but as the English were well armed, disciplined, and equipped, while only about half the Highlanders had muskets, and as they had, moreover, six pieces of artillery against the one unserviceable gun of Prince Charles, they had every reason to consider the victory to be certain.
On seeing the Highland array Cope drew up his troops in order of battle —his infantry in the centre, with a regiment of dragoons and three pieces of artillery on each flank. His right was covered by a park wall and by the village of Preston. On his left stood Seaton House, and in his rear lay the sea, with the villages of Prestonpans and Cockenzie. Their front was covered by a deep and difficult morass.
