Dictionary of National Biography, 1885-1900/Maclachlan, Lauchlan
MACLACHLAN, LAUCHLAN (d. 1746), fifteenth chief of the ancient Argyllshire clan, Lachlan (Lachuinn), of which the original stock is said to be the O'Loughlins of Meath, was served heir to his father on 23 Sept. 1719. In 1745, undeterred by the close proximity of Inverary (the seat of the Campbells), Maclachlan set out from his hereditary tower by the shores of Loch Fyne, at the head of 260 fighting men, and joined Prince Charles. He took part in the defeat of Sir John Cope at Prestonpans, and after the capture of Carlisle was sent by the prince back to Perth to expedite the movements of William Drummond, fourth viscount Strathallan [q. v.] He with his clan took part in the victory over Hawley at Falkirk, and was honourably distinguished at Culloden (16 April 1746). He was stationed in the front on the right wing in the company of the Macintoshes, the Frasers, Stewarts, Camerons, and Macleans, the last-mentioned clan being under his command as well as his own. After loudly protesting against Lord George Murray's fatal error in keeping the highland army motionless to receive the English fire, he, when the order was at last given, charged with so much impetuosity that he swept the English line of soldiers in front of him completely away, and his dead body was found considerably in the rear of the English line covered with wounds. One of his sons, an aide-de-camp of the prince, was killed when riding with the order to charge to Lord George Murray.
