They take possession of the country from John Mackay, who being unable to resist their forces, retires to the Clan Chattan to seek their support, and leaves his brother Donald Mackay to defend the country as he might.

Thereafter, Neil Nawerigh came and willingly surrendered himself to his nephews John and Donald, who caused apprehend their uncle Neil, and beheaded him at a place called Clash-nan-ceap in Strathnaver.
