Donald Dubh, XI chief of Clan Cameron, supported the Lord of the Isles, and his clansmen joined a large force of 10,000 men. This force sacked the town of Inverness and surrounding crown lands. On the return of their army to Lochaber they were intercepted by King James I of Scotland with his large army. Donald Dubh Cameron, finding himself opposed to his Sovereign, led his men in deserting the Lord of the Isles and joined forces with the King. The Clan Mackintosh are said to have done the same. The Lord of the Isles army was defeated, with Alexander MacDonald of Islay submitting to the King and being imprisoned afterwards.
