The kind-hearted Duke of Perth, seeing this slaughter, made a signal to Cameron of Lochiel to stop the impetuosity of his men; and sent his aid-de-camp, or, as he was then called, his gentleman, for that purpose. No sooner had the Duke done this, than he sprang himself upon a fleet bay mare, a racer, which had won the King's plate at Leith some years before; and, taking a Major of the King's troops along with him, "shot like an arrow through the field," and saved numbers: as also did his gentleman, Mr. Stuart.[237] But these efforts were insufficient to prevent a cruel and terrible destruction of some of the bravest and best of the British officers. In the battle of Preston Pans fell the famous Colonel Gardiner. His fate was, it is said, envied by General Cope, who, witnessing the destruction of his army, wished to have died on the field. Whilst the Highlanders were carried away to the house of Colonel Gardiner, close by, the young Chevalier stood by the road-side, having sent to Edinburgh by the advice of the Duke of Perth for surgeons. At this moment, Henderson, that spectator of the proclamation who had resolved to write a history of the war, having slept at Musselburgh, only at two miles' distance, the night before, stepped forward to take a survey of the field. "It was one scene of horror, capable," writes this historian,[238] "of softening the hardest heart, being strewed not so much with the dead as with the wounded: the broken guns, halberts, pikes, and canteens showing the work of the day. In the midst of this distressing spectacle, an act of mercy shone forth, like a light from Heaven." "Major Bowles," continues Henderson, "of Hamilton's Dragoons, being dismounted, the enemy fell upon and wounded him in eleven different places; and just as some inhuman wretch was fetching a stroke, which perhaps would have proved mortal, Mr. Stuart threw up his sword and awarded the blow."
