The Battle of Inverlochy (1431) (Scottish Gaelic: Blàr Inbhir Lochaidh) was fought after Alexander of Islay (Alasdair Ìle, Rìgh Innse Gall), Lord of the Isles and Earl of Ross, had been imprisoned by King James I. A force of Highlanders led by Donald Balloch, Alexander's cousin, defeated Royalist forces led by the Earls of Mar and Caithness at Inverlochy, near present-day Fort William. Over 1000 men were supposedly killed, among them the Earl of Caithness. Balloch then went on to ravage the country of Clan Cameron and Clan Chattan, who had been loyal to the king during the rebellion.
