The Battle

History & Significance

A naval battle off the coast of Mull between the Lord of the Isles and his illegitimate son Angus Mór Og, who had raised a rebellion against his father. Angus won and captured his father. The bitter patricidal conflict shattered the unity of the Lordship of the Isles at its most critical moment. James IV would use this internal weakness to forfeit the Lordship just a decade later (1493), ending the most powerful autonomous Gaelic political institution in Scotland.
