The king now determined to inflict summary vengeance upon his captives. Those who were most conspicuous for their crimes were immediately executed; among whom were James Campbell, who was tried, convicted, and hanged for the murder of John of the Isles; and Alexander Macreiny and John Macarthur, who were beheaded. Alexander of the Isles and Angus Dubh, after a short confinement, were both pardoned; but the latter was obliged to deliver up, as a hostage for his good behaviour, his son Neill, who was confined on the Bass rock, and, from that circumstance, was afterwards named Neill-Wasse-Mackay.[151] Besides these, many others who were kept in prison in different parts of the kingdom, were afterwards condemned and executed.
The royal clemency, which had been extended so graciously to the Lord of the Isles, met with an ungrateful return; for shortly after the king had returned to his lowland dominions, Alexander collected a force of ten thousand men in Ross and the Isles, and with this formidable body laid waste the country; plundered and devastated the crown lands, against which his vengeance was chiefly directed, and razed the royal burgh of Inverness to the ground. On hearing of these distressing events, James, with a rapidity rarely equalled, collected a force, the extent of which has not been ascertained, and marched with great speed into Lochaber, where he found the enemy, who, from the celerity of his movements, was taken almost by surprise. Alexander prepared for battle; but, before its commencement, he had the misfortune to witness the desertion of the clan Chattan, and the clan Cameron, who, to a man, went over to the royal standard. The king, thereupon, attacked Alexander’s army, which he completely routed, and the latter sought safety in flight.
Reduced to the utmost distress, and seeing the impossibility of evading the active vigilance of his pursuers, who hunted him from place to place, this haughty lord, who considered himself on a par with kings, resolved to throw himself entirely on the mercy of the king, by an act of the most abject submission. Having arrived in Edinburgh, to which he had travelled in the most private manner, the humbled chief suddenly presented himself before the king, on Easter-Sunday, in the church of Holyrood, when he and his queen, surrounded by the nobles of the court, were employed in their devotions before the high altar. The extraordinary appearance of the fallen prince denoted the inward workings of his troubled mind. Without bonnet, arms, or ornament of any kind, his legs and arms quite bare, his body covered with only a plaid, and holding a naked sword in his hand by the point, he fell down on his knees before the king, imploring mercy and forgiveness, and, in token of his unreserved submission, offered the hilt of his sword to his majesty. At the solicitation of the queen and nobles, James spared his life, but committed him immediately to Tantallan castle, under the charge of William Earl of Angus, his nephew. This took place in the year 1429. The Countess of Ross was kept in close confinement in the ancient monastery of Inchcolm, on the small island of that name, in the Frith of Forth.[152] The king, however, relented, and released the Lord of the Isles and his mother, after about a year’s imprisonment.
