Lachlan Mor Mackintosh, 16th of Mackintosh and his clan supported Mary, Queen of Scots in her victory over George Gordon, 4th Earl of Huntly at the Battle of Corrichie in 1562, where Huntly was killed. According to 19th century historian Alexander Mackintosh-Shaw, it is likely that Lachlan also fought at the Battle of Langside in 1568 as five days before the battle he had subscribed to a band for the Queen's defence at the town of Hamilton, South Lanarkshire. Of the 136 subscribing barons and chiefs, apart from Mackintosh only two others were Highland chiefs: George Gordon, 5th Earl of Huntly and Alexander Gordon, 12th Earl of Sutherland.
