Then, and all through this meteoric campaign, the conduct of Charles was characterized by a sincere humanity, which stands out in startling contrast with the cruelties practised later by his enemy, the "Butcher of Cumberland." It prevented the Prince from gaining an important military advantage by the reduction of Edinburgh castle. He attempted the reduction of the castle by cutting off its supplies, but, when the general in command threatened to open fire upon the town in consequence, Charles immediately rescinded the order, although his officers urged that the destruction of a few houses, and even the loss of a few lives, was, in a military sense, of scant importance in comparison with the capture of so valuable a stronghold as Edinburgh castle. The Prince held firmly to his resolve, and Edinburgh castle remained to the end in the hands of the royal troops. Charles displayed a great objection, too, to any plundering or lawless behavior on the part of his wild Highland army. We learn from the Bland Burges papers that when the house of Lord Somerville, who was opposed to the Prince, was molested by a party of Highlanders, the Prince, on hearing of it, sent an apology to Lord Somerville, and an officer's guard to protect him from further annoyance.
But time was running on, and it was necessary to take action again. England was waking up to a sense of its peril. Armies were gathering. The King had come back from Hanover, the troops were almost all recalled from Flanders. It was time to make a fresh stroke. Charles resolved upon the bold course of striking south at once for England, and early in November he marched. He set off on the famous march south. In this undertaking, as before, the same extraordinary good-fortune attended upon the Stuart arms. His little army of less than six thousand men reached Carlisle, reached Manchester, without opposition. On December 4th he was at Derby, only one hundred twenty-seven miles from London. Once again, by skill or by good-fortune, he had contrived to slip past the English general sent out to bar his way. Cumberland with his forces was at Stafford, nine miles farther from the capital than the young Prince, who was now only six days from the city, with all his hopes and his ambitions ahead of him, and behind him the hostile army of the general he had eluded.
