Sir Robert Gordon (1580–1656) wrote an account of the battle in his book, the
Genealogical History of the Earldom of Sutherland: In the days of Robert, Earl of Sutherland, the year 1426, Angus-Dow Mackay, and his son Niel, assembling all the forces of
Strathnaver, they entered into Caithness with all hostility, and spoiled the same. The inhabitants of Caithness convened with all diligence, and fought against Angus-Dow Mackay at Harpsdale, where there was great slaughter on either side. The report hereof came to the ears of King James the First, who thereupon came north to Inverness, of intention to pursue Angus-Dow Mackay. Hearing of the king's being at
Inverness, he came and submitted himself to the king's mercy, and gave his son Niel in pledge for his good obedience from thenceforward: which submission the king accepted, and sent Niel Mackay to remain in captivity on the
Bass Rock who from thenceforth was always called Niel-Bass Mackay. ==Aftermath==
