 Having complained for several years about harassment from the MacLeans, in 1647 the Campbells launched a surprise attack on Aros Castle, and killed many MacLeans; for many years in the 20th century, a human skull stood on a ledge in a nearby cave, and it was traditionally said to have been the remains of a Maclean who had been killed in this battle.The skull is no longer there, but the latest editions of Ordnance Survey maps still mark the location as 'Maclean's Skull Cave'.The north of the island, however, remained in MacLean hands until 1737, when it was sold to Donald MacNeil of Colonsay.
