Duncan tells us that this and other of these stories were obtained from "a person who was well known to possess a strong memory of undoubted veracity, and who was himself an eye-witness to many of the circumstances".
Another of the stories related by Duncan is the following --
"Munro had suspicion or intelligence that Cluny would be at the christening of a child of Hugh Macphersons of Uvie. He accordingly surrounded the house with a strong party before daylight, and such was his courage that he forced himself in through a window into a room where he supposed the Chief would be in bed. Fortunately for himself he only found the visiting minister before him, for Cluny was always well armed and fully resolved never to be taken alive."
Yet another tale with an authentic basis to it concerns a tenant of Cluny--
"James Leslie was met by a party of soldiers as he returned from one of Cluny's caves, and as he had a tablecloth and some dishes, they rightly concluded he had been with some victuals to him, and threatened him with instant death if they did not lead them to his hiding-place. Leslie declared he knew nothing about him, and had not seen Cluny for twelve months. They desired him to make oath to that effect, and he accordingly swore point blank on a drawn sword (a mode of swearing held most sacred in the Highlands at that time), that he did not know where he was, and that he did not see him for twelve months back. Being asked what he had been doing with the dishes, he declared he had been with the breakfast for people casting peats."
It's of interest to know that, according to Duncan, his father was more likely to take the Leslies into his confidence as to his location believing that they would be less likely to be suspected or susceptible to coercion than his Macpherson clansmen.
