The battle of Falkirk, which in itself appeared so brilliant an affair for Prince Charles, was really one of his most serious disasters. The Highlanders, according to their regular custom when loaded with plunder, went off in great numbers to their homes with their booty. His chief officers became furious against each other in discussing their respective merits in the battle. Lord George Murray, who had himself behaved most bravely in the field, complained that Lord John Drummond had not exerted himself, or pursuit might have been made and the royal army been utterly annihilated. This spirit of discontent was greatly aggravated by the siege of the castle of Stirling. Old General Blakeney, who commanded the garrison, declared he would hold out to the last man, in spite of the terrible threats of Lord George Murray if he did not surrender. The Highlanders grew disgusted with work so contrary to their habits; and, indeed, the French engineer, the so-called Marquis de Mirabelle, was so utterly ignorant of his profession, that the batteries which he constructed were commanded by the castle, and the men were so much exposed that they were in danger of being destroyed before they took the fortress. Accordingly, on the 24th of January they struck to a man, and refused to go any more into the trenches. This was followed by a memorial, signed by most of the chief officers, including Lord George Murray, Lochiel, Keppoch, Clanranald, and Simon Fraser, Master of Lovat. This was sent by Lord George to Charles, and represented that so many men were gone home, and more still going, in spite of all the endeavours of their chiefs, that if the siege were continued they saw nothing but absolute destruction to the whole army. The prince sent Sir Thomas Sheridan to remonstrate with the chiefs, but they would not give way, and Charles, it is said, sullenly acquiesced in the retreat.
