As the alliance of such a powerful and war-like chief as Mackay would have been of great importance to the Sutherland interest, an attempt was made to detach him from the Earl of Caithness. The plan appears to have originated with Hugh Murray of Aberscors, who made repeated visits to Strathbogie, to consult with the Earl of Sutherland and his friends on this subject, and afterwards went into Strathnaver and held a conference with Mackay, whom he prevailed upon to accompany him to Strathbogie. Mackay then entered into an engagement with the Earl of Huntly and the Earl of Sutherland, to assist the latter against the Earl of Caithness, in consideration of which, and on payment of £300 Scots, he obtained from the Earl of Huntly the heritable right and title of the lands of Strathnaver; but Mackay, influenced by Barbara Sinclair, the wife of the Earl of Sutherland, with whom he now publicly cohabited, broke his engagement, and continued to oppress the earl’s followers and dependents.

From some circumstances which have not transpired, the Earl of Caithness became suspicious of his son John, the Master of Caithness, as having, in connection with Mackay, a design upon his life. To put an end to the earl’s suspicion, Mackay advised John to go to Girnigo (Castle Sinclair), and to submit himself to his father’s pleasure, a request with which the Master complied; but, after arriving at Girnigo, he was, while conversing with his father, arrested by a party of armed men, who, upon a secret signal being given by the earl, had rushed in at the chamber door. He was instantly fettered and thrust into prison within the castle, where, after a miserable captivity of seven years, he died, a prey to famine and vermin.

Mackay, who had accompanied the Master to Girnigo, and who in all probability would have shared the same fate, escaped and returned home to Strathnaver, where he died, within four months thereafter, of grief and remorse for the many bad actions of his life. During the minority of his son Houcheon, John Mor-Mackay, the cousin, and John Beg-Mackay, the bastard son of Y-Mackay, took charge of the estate; but John Mor-Mackay was speedily removed from his charge by the Earl of Caithness, who, considering him as a favourer of the Earl of Sutherland, caused him to be apprehended and carried into Caithness, where he was detained in prison till his death. During this time John Robson, the chief of the clan Gun in Caithness and Strathnaver, became a dependent on the Earl of Sutherland, and acted as his factor in collecting the rents and duties of the bishop’s lands within Caithness which belonged to the earl. This connexion was exceedingly disagreeable to the Earl of Caithness, who in consequence took a grudge at John Robson, and, to gratify his spleen, he instigated Houcheon Mackay to lay waste the lands of the clan Gun, in the Brea-Moir, in Caithness, without the knowledge of John Beg-Mackay, his brother. As the clan Gun had always been friendly to the family of Mackay, John Beg-Mackay was greatly exasperated at the conduct of the earl in enticing the young chief to commit such an outrage; but he had it not in his power to make any reparation to the injured clan. John Robson, the chief, however, assisted by Alexander Earl of Sutherland, invaded Strathnaver and made ample retaliation. Meeting the Strathnaver men at a place called Creach-Drumi-Doun, he attacked and defeated them, killing several of them, and chiefly those who had accompanied Houcheon Mackay in his expedition to the Brea-Moir. He then carried off a large quantity of booty, which he divided among the clan Gun of Strathully, who had suffered by Houcheon Mackay’s invasion.[183]

The Earl of Caithness, having resolved to avenge himself on John Beg-Mackay for the displeasure shown by him at the conduct of Houcheon Mackay, and also on the clan Gun, prevailed upon Neill-Mac-Iain-Mac-William, chief of the Sliochd-Iain-Abaraich, and James Mac-Rory, chief of the Sliochd-Iain-Mhoir, to attack them. Accordingly, in the month of September, 1579, these two chiefs, with their followers, entered Balnekill in Durines during the night-time, and slew John Beg-Mackay and William Mac-Iain-Mac-Rob, the brother of John Robson, and some of their people. The friends of the deceased were not in a condition to retaliate, but they kept up the spirit of revenge so customary in those times, and only waited a favourable opportunity to gratify it. This did not occur till several years thereafter. In the year 1587, James Mac-Rory, “a fyne gentleman and a good commander,” according to Sir Robert Gordon, was assassinated by Donald Balloch-Mackay, the brother of John Beg-Mackay; and two years thereafter John Mackay, the son of John Beg, attacked Neill Mac-Iain-Mac-William, whom he wounded severely, and cut off some of his followers. “This Neill,” says Sir R. Gordon, “heir mentioned, wes a good captain, bold, craftie, of a verie good witt, and quick resolution.”

After the death of John Beg-Mackay, and William Mac-Iain-Mac-Rob, a most deadly and inveterate feud followed, between the clan Gun and the Sliochd-Iain-Abaraich, but no recital of the details has been handed down to us. “The long, the many, the horrible encounters,” observes Sir R. Gordon “which happened between these two trybes, with the bloodshed, and infinit spoills committed in every pairt of the diocy of Catteynes by them and their associats, are of so disordered and troublesome memorie, that, what with their asperous names, together with the confusion of place, tymes, and persons, would yet be (no doubt) a warr to the reader to overlook them; and therefor, to favor myne oune paines, and his who should get little profite or delight thereby, I doe pass them over.”[184]

The clan Chattan, about this time, must have been harassing the surrounding districts to a terrible extent, and causing the government considerable trouble, as in 1583 we find a mandate addressed by King James “to our shirreffs of Kincardin, Abirdene, Banf, Elgen, Fores, Narne, and Invernyss; and to our derrest bruthir, James, Erle of Murray, our lieutenant generale in the north partis of our realme, and to our louittis consingis [ ... ] Erle of Suthirland; John Erle of Cathnes,” &c., &c., commanding them that inasmuch as John M’Kinlay, Thomas Mackinlay, Donald Glass, &c., “throcht assistance and fortifying of all the kin of Clanquhattane duelland within Baienach, Petty, Brauchly, Strathnarne, and other parts thereabout, committs daily fire-raising, slaughter, murder, heirschippis, and wasting of the cuntre,” to the harm of the true lieges, these sheriffs and others shall fall upon the “said Clanquhattane, and invade them to their utter destruction by slaughter, burning, drowning, and other ways; and leave na creature living of that clan, except priests, women, and bairns.” The “women and bairns” they were ordered to take to “some parts of the sea nearest land, quhair ships salbe forsene on our expenses, to sail with them furth of our realme, and land with them in Jesland, Zesland, or Norway; because it were inhumanity to put hands in the blood of women and bairns.” Had this mandate for “stamping out” this troublesome clan been carried out it would certainly have been an effectual cure for many of the disturbances in the Highlands; but we cannot find any record as to what practical result followed the issue of this cruel decree.[185]

In the year 1585 a quarrel took place between Neill Houcheonson, and Donald Neilson, the Laird of Assynt, who had married Houcheon Mackay’s sister. The cause of Donald Neilson was espoused by Houcheon Mackay, and the clan Gun, who came with an army out of Caithness and Strathnaver, to besiege Neill Houcheonson in the isle of Assynt. Neill, who was commander of Assynt, and a follower of the Earl of Sutherland, sent immediate notice to the earl of Mackay’s movements, on receiving which the earl, assembling a body of men, despatched them to Assynt to raise the siege; but Mackay did not wait for their coming, and retreated into Strathnaver. As the Earl of Caithness had sent some of his people to assist Mackay, who was the Earl of Sutherland’s vassal, the latter resolved to punish both, and accordingly made preparations for entering Strathnaver and Caithness with an army. But some mutual friends of the parties interfered to prevent the effusion of blood, by prevailing on the two earls to meet at Elgin, in the presence of the Earl of Huntly and other friends, and get their differences adjusted. A meeting was accordingly held, at which the earls were reconciled. The whole blame of the troubles and commotions which had recently disturbed the peace of Sutherland and Caithness, was thrown upon the clan Gun, who were alleged to have been the chief instigators, and as their restless disposition might give rise to new disorders, it was agreed, at said meeting, to cut them off, and particularly that part of the tribe which dwelt in Caithness, which was chiefly dreaded, for which purpose the Earl of Caithness bound himself to deliver up to the Earl of Sutherland, certain individuals of the clan living in Caithness. To enable him to implement his engagement a resolution was entered into to send two companies of men against those of the clan Gun who dwelt in Caithness and Strathnaver, and to surround them in such a way as to prevent escape. The Earl of Caithness, notwithstanding, sent private notice to the clan of the preparations making against them by Angus Sutherland of Mellary, in Berriedale; but the clan were distrustful of the earl, as they had already received secret intelligence that he had assembled his people together for the purpose of attacking them.

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.

The Earl of Caithness afterwards confessed that he had no intention of attacking the clan Gun at the time in question; but that his policy was to have allowed them to be closely pressed and pursued by the Sutherland men, and then to have relieved them from the imminent danger they would thereby be placed in, so that they might consider that it was to him they owed their safety, and thus lay them under fresh obligations to him. But the deceitful part he acted proved very disastrous to his people, and the result so exasperated him against the clan Gun, that he hanged John Mac-Iain-Mac-Rob, chieftain of the clan Gun, in Caithness, whom he had kept captive for some time.
