During Iain Mishealbhach's tenure as guardian, the MacLeods of Harris and Dunvegan were at their lowest point in their history.Many of the clan opposed the selection of Iain Mishealbhach, favouring instead Tormod Coil who slew Alastair Cannoch at the Battle of Sligachan.Following these victories, the MacDonalds besieged Dunvegan Castle, where the widow of William Cleireach was living at the time.Iain Borb swore his vassalage to the Lord of the Isles and in accordance to this agreement fought under the MacDonalds at the Battle of Harlaw in 1411.[1] Early 20th century Clan Donald historians A. and A. Macdonald, however, stated that both clans of MacLeods were in the main body of men commanded by Domhnall and that the right wing was made up of MacLeans, commanded by Hector MacLean of Duart (Red Hector of the Battles).The manuscript tells how during a fencing match with his foster-brother, Somerled MacConn, Iain Borb's wound began to bleed so profusely that he bled to death.[7] According to MacKinnon, one of the daughters, Margaret, married Roderick MacLeod of Lewis (6th clan chief).[1] The late 19th-century clan historian A.M. Sinclair stated that her name was Finvola and noted that the couple had two sons, Neil and John Garbh.
