Conflict between Alexander of Islay, Earl of Ross and James I of Scotland Conflict between Aonghas Óg and James III of Scotland Conflict between John of Islay, Earl of Ross and James IV of Scotland Rebellion of Domhnall Dubh The Battle of Inverlochy (1431) (Scottish Gaelic: Blàr Inbhir Lòchaidh) 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.

When King James finally set Alexander free, he was the only magnate who could offer security in the Highlands.

Upon the king's murder in 1437, Alexander was again recognized as the Earl of Ross, and not only received control of Dingwall, but Inverness, too, which he would hold until at least 1447.

The pibroch The End of the Great Bridge is traditionally held to have been composed during the battle and Piobaireachd Domhnull Dubh, named for clan chief Donald Dubh Cameron, commemorates the battle.

Finally, in February 1439, Alexander was appointed Justiciar of Scotia, an office which made him the chief legal official in the Kingdom of Scotland.
