Clan Cameron defended their lands against the Clan MacLean. Clan Cameron won the battle. Prior to this the Cameron lands had been bestowed upon John Garve Maclean of Coll by Alexander, Lord of the Isles. It is recorded that a young Maclean Chieftain, Ewen/John Abrach (the son of John Garve Maclean, so called from his residence in Lochaber) was killed in this battle. It is not likely that this is one in the same with "Hector Bui M'Lean." Rather, they were possibly the leaders of their respective tribes of the Macleans. With the defeat of the Macleans at Corpach, the Camerons continued to retain their lands, despite Maclean attempts to "dislodge" them.
