On 3 September 1631 Sir Lachlan Maclean created a Baronet of Nova Scotia. Later during the Scottish Civil War he was devoted to Charles I of England and called out his clan to fight for James Graham, 1st Marquis of Montrose who was the king's captain general. The Clan Maclean fought as royalists at the Battle of Inverlochy (1645), Battle of Auldearn and Battle of Kilsyth, alongside men from Clan MacDonald, and other allies from Ireland raised by Alasdair MacColla. Their enemy was the Scottish Argyll government forces of Clan Campbell, led by Archibald Campbell, 1st Marquess of Argyll. Through cunning tactics the Royalist force of 1500 MacDonalds and MacLeans defeated the Argyll Campbell force of 3000.
