Montrose had advanced as far as Loch Katrine, when a messenger brought him intelligence that General Hurry was in the Enzie with a considerable force, that he had been joined by some of the Moray-men, and, after plundering and laying waste the country, was preparing to attack Lord Gordon, who had not a sufficient force to oppose him. On receiving this information, Montrose resolved to proceed immediately to the north to save the Gordons from the destruction which appeared to hang over them, hoping that, with such accessions of force as he might obtain in his march, united with that under Lord Gordon, he would succeed in defeating Hurry before Baillie should be aware of his movements.

He, therefore, returned through Balquidder, marched, with rapid strides, along the side of Loch Tay, through Athole and Angus, and, crossing the Grampian hills, proceeded down the Strath of Glenmuck. In his march, Montrose was joined by the Athole-men and the other Highlanders who had obtained, or rather taken leave of absence after the battle of Inverlochy, and also by Macdonald and his party. On arriving in the neighbourhood of Auchindoun, he was met by Lord Gordon, at the head of 1,000 foot and 200 horse. Montrose crossed the Dee on the 1st of May, at the mill of Crathie—having provided himself with ammunition from a ship in Aberdeen harbour—continued his march towards the Spey, and before Hurry was even aware that the enemy had crossed the Grampians, he found them within six miles of his camp. The sudden appearance of Montrose with such a superior force—for Hurry had only at this time about 1,000 foot and 200 horse—greatly alarmed him, and raising his camp, he crossed the Spey in great haste, with the intention of marching to Inverness, where he would be joined by the troops of the garrison, and receive large reinforcements from the neighbouring counties. Montrose immediately pursued him, and followed close upon his heels to the distance of 14 miles beyond Forres, when, favoured by the darkness of the night, Hurry effected his escape, with little loss, and arrived at Inverness.

The panic into which Hurry had been thrown soon gave way to a very different feeling, as he found the Earls of Seaforth and Sutherland with their retainers, and the clan Fraser, and others from Moray and Caithness, all assembled at Inverness, as he had directed. This accession of force increased his army to 3,500 foot and 400 horse. He therefore resolved to act on the offensive, by giving battle to Montrose immediately.

Montrose had taken up a position at the village of Auldearn, about three miles south-east from Nairn, on the morning after the pursuit. In the course of the day, Hurry advanced with all his forces, including the garrison of Inverness, towards Nairn; and, on approaching Auldearn, formed his army in order of battle. Montrose’s force, which had been greatly weakened by the return of the Athole-men and other Highlanders to defend their country from the depredations of Baillie’s army, now consisted of only 1,500 foot and 250 horse. It was not, therefore, without great reluctance, that he resolved to risk a battle with an enemy more than double in point of numbers, and composed in great part of veteran troops; but, pressed as he was by Hurry, and in danger of being attacked in his rear by Baillie, who was advancing by forced marches to the north, he had no alternative but to hazard a general engagement. He therefore instantly looked about him for an advantageous position.

The village of Auldearn stands upon a height, behind which, or on the east, is a valley, overlooked by a ridge of little eminences, running in a northerly direction, and which almost conceals the valley from view. In this hollow Montrose arranged his forces in order of battle. Having formed them into two divisions, he posted the right wing on the north of the village, at a place where there was a considerable number of dikes and ditches. This body, which consisted of 400 men, chiefly Irish, was placed under the command of Macdonald. On taking their stations, Montrose gave them strict injunctions not to leave their position on any account, as they were effectually protected by the walls around them, not only from the attacks of cavalry, but of foot, and could, without much danger to themselves, keep up a galling and destructive fire upon their assailants. In order to attract the best troops of the enemy to this difficult spot where they could not act, and to make them believe that Montrose commanded this wing, he gave the royal standard to Macdonald, intending, when they should get entangled among the bushes and dikes, with which the ground to the right was covered, to attack them himself with his left wing; and to enable him to do so the more effectually, he placed the whole of his horse and the remainder of the foot on the left wing to the south of the village. The former he committed to the charge of Lord Gordon, reserving the command of the latter to himself. After placing a few chosen foot with some cannon in front of the village, under cover of some dikes, Montrose firmly awaited the attack of the enemy.

Hurry divided his foot and his horse each into two divisions. On the right wing of the main body of the foot, which was commanded by Campbell of Lawers, Hurry placed the regular cavalry which he had brought from the south, and on the left the horse of Moray and the north, under the charge of Captain Drummond. The other division of foot was placed behind as a reserve, and commanded by Hurry himself.

When Hurry observed the singular position which Montrose had taken up, he was utterly at a loss to guess his designs, and though it appeared to him, skilful as he was in the art of war, a most extraordinary and novel sight, yet, from the well known character of Montrose, he was satisfied that Montrose’s arrangements were the result of a deep laid scheme. But what especially excited the surprise of Hurry, was the appearance of the large yellow banner or royal standard in the midst of a small body of foot stationed among hedges and dikes and stones, almost isolated from the horse and the main body of the foot. To attack this party, at the head of which he naturally supposed Montrose was, was his first object. This was precisely what Montrose had wished; his snare proved successful. With the design of overwhelming at once the right wing, Hurry despatched towards it the best of his horse and all his veteran troops, who made a furious attack upon Macdonald’s party, the latter defending themselves bravely behind the dikes and bushes. The contest continued for some time on the right with varied success, and Hurry, who had plenty of men to spare, relieved those who were engaged by fresh troops. Montrose, who kept a steady eye upon the motions of the enemy, and watched a favourable opportunity for making a grand attack upon them with the left wing, was just preparing to carry his design into execution, when a confidential person suddenly rode up to him and whispered in his ear that the right wing had been put to flight.

This intelligence was not, however, quite correct. It seems that Macdonald who, says Wishart, “was a brave enough man, but rather a better soldier than a general, extremely violent, and daring even to rashness,” had been so provoked with the taunts and insults of the enemy, that in spite of the express orders he had received from Montrose on no account to leave his position, he had unwisely advanced beyond it to attack the enemy, and though he had been several times repulsed he returned to the charge. But he was at last borne down by the great numerical superiority of the enemy’s horse and foot, consisting of veteran troops, and forced to retire in great disorder into an adjoining enclosure. Nothing, however, could exceed the admirable manner in which he managed this retreat, and the courage he displayed while leading off his men. Defending his body with a large target, he resisted, single-handed, the assaults of the enemy, and was the last man to leave the field. So closely indeed was he pressed by Hurry’s spearmen, that some of them actually came so near him as to fix their spears in his target, which he cut off by threes or fours at a time with his broadsword.[293]

It was during this retreat that Montrose received the intelligence of the flight of the right wing; but he preserved his usual presence of mind, and to encourage his men, who might get alarmed at hearing such news, he thus addressed Lord Gordon, loud enough to be heard by his troops, “What are we doing, my Lord? Our friend Macdonald has routed the enemy on the right and is carrying all before him. Shall we look on and let him carry off the whole honour of the day?” A crisis had arrived, and not a moment was to be lost. Scarcely, therefore, were the words out of Montrose’s mouth, when he ordered his men to charge the enemy. When his men were advancing to the charge, Captain or Major Drummond, who commanded Hurry’s horse, made an awkward movement by wheeling about his men, and his horse coming in contact with the foot, broke their ranks and occasioned considerable confusion. Lord Gordon seeing this, immediately rushed in upon Drummond’s horse with his party and put them to flight. Montrose followed hard with the foot, and attacked the main body of Hurry’s army, which he routed after a powerful resistance. The veterans in Hurry’s army, who had served in Ireland, fought manfully, and chose rather to be cut down standing in their ranks than retreat; but the new levies from Moray, Ross, Sutherland, and Caithness, fled in great consternation. They were pursued for several miles, and might have been all killed or captured if Lord Aboyne had not, by an unnecessary display of ensigns and standards, which he had taken from the enemy, attracted the notice of the pursuers, who halted for some time under the impression that a fresh party of the enemy was coming up to attack them. In this way Hurry and some of his troops, who were the last to leave the field of battle, as well as the other fugitives, escaped from the impending danger, and arrived at Inverness the following morning. As the loss of this battle was mainly owing to Captain Drummond, he was tried by a court-martial at Inverness, and condemned to be shot, a sentence which was carried into immediate execution. He was accused of having betrayed the army, and it is said that he admitted that after the battle had commenced he had spoken with the enemy.[294]

The number of killed on both sides has been variously stated. That on the side of the Covenanters has been reckoned by one writer at 1,000,[295] by another[296] at 2,000, and by a third at 3,000 men.[297] Montrose, on the other hand, is said by the first of these authors to have lost about 200 men, while the second says that he had only “some twenty-four gentlemen hurt, and some few Irish killed,” and Wishart informs us that Montrose only missed one private man on the left, and that the right wing, commanded by Macdonald, “lost only fourteen private men.” The clans who had joined Hurry suffered considerably, particularly the Frasers, who, besides unmarried men, are said to have left dead on the field no less than 87 married men. Among the principal covenanting officers who were slain were Colonel Campbell of Lawers, Sir John and Sir Gideon Murray, and Colonel James Campbell, with several other officers of inferior note. The laird of Lawers’s brother, Archibald Campbell, and a few other officers, were taken prisoners. Captain Macdonald and William Macpherson of Invereschie were the only persons of any note killed on Montrose’s side. Montrose took several prisoners, whom, with the wounded, he treated with great kindness. Such of the former as expressed their sorrow for having joined the ranks of the Covenanters he released—others who were disposed to join him he received into his army, but such as remained obstinate he imprisoned. Besides taking 16 standards from the enemy, Montrose got possession of the whole of their baggage, provisions, and ammunition, and a considerable quantity of money and valuable effects. The battle of Auldearn was fought on the 4th of May, according to Wishart,[298] and on the 9th according to others,[299] in the year 1645.
