As soon as the Earl of Sutherland could get his men collected he proceeded to march to the territories of the clan Gun; but meeting by chance, on his way, with a party of Strathnaver men, under the command of William Mackay, brother of Houcheon Mackay, carrying off the cattle of James Mac-Rory, a vassal of his own, from Coireceann Loch in the Diri-Meanigh, he rescued and brought back his vassal’s cattle. After this the earl’s party pursued William Mackay and the Strathnaver men during the whole day, and killed one of the principal men of the clan Gun in Strathnaver, called Angus-Roy, with several others of Mackay’s company. This affair was called Latha-Tom-Fraoich, that is, the day of the heather bush. At the end of the pursuit, and towards evening, the pursued party found themselves on the borders of Caithness, where they found the clan Gun assembled in consequence of the rising of the Caithness people who had taken away their cattle. This accidental meeting of the Strathnaver men and the clan Gun was the means, probably, of saving both from destruction. They immediately entered into an alliance to stand by one another, and to live or die together. Next morning they found themselves placed between two powerful bodies of their enemies. On the one side was the Earl of Sutherland’s party at no great distance, reposing themselves from the fatigues of the preceding day, and on the other were seen advancing the Caithness men, conducted by Henry Sinclair, brother to the laird of Dun, and cousin to the Earl of Caithness. A council of war was immediately held to consult how to act in this emergency, when it was resolved to attack the Caithness men first, as they were far inferior in numbers, which was done by the clan Gun and their allies, who had the advantage of the hill, with great resolution. The former foolishly expended their arrows while at a distance from their opponents; but the clan Gun having husbanded their shot till they came in close contact with the enemy, did great execution. The Caithness men were completely over-thrown, after leaving 140 of their party, with their captain, Henry Sinclair, dead on the field of battle. Had not the darkness of the night favoured their flight, they would have all been destroyed. Henry Sinclair was Mackay’s uncle, and not being aware that he had been in the engagement till he recognised his body among the slain, Mackay felt extremely grieved at the unexpected death of his relative. This skirmish took place at Aldgown, in the year 1586. The Sutherland men having lost sight of Mackay and his party among the hills, immediately before the conflict, returned into their own country with the booty they had recovered, and were not aware of the defeat of the Caithness men till some time after that event.
