[7] The evidence is also ample that the Rosses managed to secure some of these lands lying in the parishes of Edderton and Kincardine in Ross-shire.

Sir Robert Gordon, 1st Baronet's manuscript, A Genealogical History of the Earldom of Sutherland, was written in about 1630 and says the following for the battle: In the dayes of this John Earle Southerland, the battell of Aldycharrish was foughtin, the eleventh day of Julie 1487, upon this occasion: Angus Macky (the sone of Neill Gald, or Neill-Wasse-Macky) being slain at Tarbat by the surname of Rosse, as I have shewen alreadie, John Reawigh Macky (the sone of this Angus) came to John Earle of Southerland, upon whom he depended, and desired, he sayd, to revenge his father's death: whereunto Earle John yeelded, and presentie sent his uncle, Robert Southerland, with a company of chosen men, to assist him.

So Robert Southerland, John Reawigh Macky, and William-Dow-Mack -Ean-Abreigh, did invade Strath-oy-kell with fyre and sword, burnt, spoilled, and wasted many lands apperteyning to the Rosses.

In end, the inhabitants of Rosse, being unable to indure the enemies force, were untterly disbanded and put to flight.

It quotes as sources the manuscripts of Fern and Beuly: That year also happened to be fatall for a bloody conflict fell out at Altcharrish in Brea Rosse upon this occasion.

Anguis Macky being slain at Tarbut, anno 1438, by the Rosses, as was reported, John Revach M'ky his sone came to the Earle of Sutherland, upon whom he depended, and desired his Lordships aid and concurrance to revenge his fathers death, to which the Earl of Sutherland as a bad neighbour, and a worse judge, yelds, and sent his own uncle, Robert Sutherland, with a company of men, along with John Revach to invade Rosse, they joining together, being furious and forward enugh, they fell upon Strathoikell and Strathcharron with fire and sword, burnt, plundered, and laid wast divers lands appertaining to the Rosses, the Laird of Ballnigown, cheefe of the Rosses, getting sudden advertisement of the attempt, a great losse, convocats all his fensible men, and at a randivous near Edderton, piled out 400 men, with quhom he marcht in person, and met Robert Sutherland and John Revach at a passe in Strathoickel called Altcharrish, and there ensued a dreadfull conflict which continued hot a full day with incredible currage and furry and much blood on both sids.

Alexander Ross, Laird of Ballnigown, was there slaine, with 70 other landed gentlemen of his name, besids a considerable number of commone soldiers: also Robert Sutherland fell in that field and merito qho came theire to court his death.

Thereupon Robert Sutherland and John Riabhach Mackay did invade Strathoyckel and Strathcarron with fire and sword; burnt, spoiled, and laid waste divers lands appertaining to the Rosses.

There ensued a cruel and furious conflict combat, which continued a long time, with incredible obstinacy; much blood was shed on either side.

In the end, the inhabitants of Ross being unable to endure or resist the enemies' forces were utterly disbanded and put to flight.

Ross of Balnagown immediately raised all of the power of the county to oppose the invaders, upon which a most severe conflict ensued, and for a considerable time it appeared doubtful which party would have the victory.

Sir Robert states that the Assint-men insisted that the men of Sutherland should receive no share of the spoil, but that William-Dow, who detected such injustice, said, that he should be an enemy to any who would act such a fraudulent and base part.

[17] On 15 March 1504, Iye Roy Mackay, 10th of Strathnaver secured from the king the lands of Ferencostrig, Strathhalladale, Creichmore, Assent, Coigach, Gruids, and Strathfleet.

[17] The Mackays continued to raid the Rosses well into the 16th century and did not stop until they became caught up in quarrels with their neighbours, the powerful Clan Sutherland.
