Returning from the west country, Agricola entered upon the campaign of three years' duration, which issued in the Battle of Mons Grampus, the crowning glory of his arms in Scotland, and the immediate occasion of his recall. He chose the alternative route this time. From his chain of forts he could see the broad expanse of the Firth of Forth, the coast of Fife, the central Lomonds, and the distant hill-country, whose acquaintance he had already made. That distant point was the goal of his endeavour, and the shortest way to it was across the Firth of Forth, through the western division of Fife, and on by one of the Ochil passes—Glendevon, or some other further east into Strathearn. There was no time to lose. For, while he was engaged in the subjugation of Fife, the fleet, after exploring the harbours, had doubled the East Neuk, passed safely through St Andrews Bay, and entered the Firth of Tay. Its unexpected appearance caused the greatest consternation among the Caledonians. The immediate result was to greatly increase the peril in which the devoted garrisons in Strathearn stood. So great was their danger, and so well was it known, that there were those with Agricola who advised a retreat to the chain of forts between the Firths. But Agricola was not to be shaken in his resolve, which was to finally break the power of the tribes who dwelt to the north and east of the Grampians, and who, so long as they remained free and unchastised, were a standing menace to the Strath of the Earn and to the garrisons who held it at the hazard of their lives. He formed a camp to winter in at a place called Grassy Walls, on the east side of the Tay, near to Perth. But there was still time, before the winter set in, for a little exploration and a brush with the enemy to revive the courage of his soldiers, which had begun to droop a little. Advancing northward on the left bank of the river, Agricola reached the Isla, and not caring to cross it so late in the year, in the face of the enemy who were massed upon the Hill and Muir of Blair beyond, he diverged to the right, following the course of the Isla until he came to the place where Coupar Angus stands now. Here he paused. He had marched from Perth in three divisions to prevent surprise, and in this neighbourhood there are three positions marked by Roman remains that correspond with these divisions. The main force was stationed at Coupar Angus; the Ninth Legion at Lintrose, two miles south-east; a third small body at a place two miles south-west, overlooking the Tay, and guarding the passage. These details are important, as helping to determine the true site of the Battle of Mons Grampus. It may be taken for granted that the Roman General made good use of his opportunity to survey the ground upon which the decisive battle was fought. Before retiring to winter quarters at Grassy Walls, the Roman soldiers had a chance given them of testing the strength and valour of the Caledonians. The Ninth Legion was stationed at Lintrose, and here the enemy delivered their attack under cover of night. They had penetrated into the camp ere they were discovered, and it might have gone hard with the Legion if help had not been at hand. But the alarm quickly spread to where Agricola was stationed with the main body. On his arrival the Caledonians took to flight. With the first touch of winter the march southward was begun, and when the summer came the legionaries and the auxiliaries clamoured impatiently to be led northward to the final encounter.
The theory maintained in this paper regarding the last campaign of Agricola, and the site of the Battle of Mons Grampus was first broached in the Statistical Account of the parish of Bendochy, published in 1797. It has been since adopted by Skene in his classical work on Celtic Scotland, to which I desire in this place to acknowledge my great indebtedness. Other sites have been fixed upon, but there are none that can fairly be put in comparison with the neck of land at the junction of the Isla with the Tay. What may be called the traditional view of the site of the battle locates it at Ardoch, in the vicinity of the great camp. No doubt, good authorities can be quoted in favour of the correctness of the traditional view. But there are several reasons which render it highly improbable that the great battle was fought at Ardoch. The very name Mons Grampus implies the existence of some conspicuous eminence in the near neighbourhood. There is no such eminence near Ardoch. Further, we know that Agricola's scheme of operation embraced joint action on the part of the fleet and land forces. There could have been no such co-operation if the movement of the legions had been west of the Tay. And it is a fatal objection to the Ardoch site that there are not three stations corresponding to those which we have seen the three divisions of Agricola's force occupied on the night of the surprise. General Roy, indeed, has tried to turn the edge of this objection by placing the Ninth Legion at Dalginross, the main body under Agricola at Ardoch, and the other division at Strageath, overlooking and guarding the Earn. But it has been retorted upon him that Agricola could have made no worse disposition of his forces, from a strategic point of view, than to have stationed his weakest division at Comrie, nine miles distant from the main body, in the very heart of the enemy's country, close to the hills, from which they could rush down upon any favourable opportunity, and to which they could retreat in the event of a repulse.
Besides, help came from the main body in the course of a few hours—between night and morning. It would be a difficult task even now for a body of men to cover the ground between Ardoch and Comrie in the dead of night; and we must remember that in the time of Agricola the country was a pathless wild, rough with woods in the higher parts, and covered with treacherous morasses in the valleys. The Damnonii—within whose territories Ardoch, Comrie, and Strageath lay—were more highly civilised than the Caledonians beyond the Tay and the Grampian range. They had towns, as we have seen; they probably engaged to some extent in agriculture; their food did not altogether consist of fish, milk, and the produce of the chase. But their towns were few and far between, and the means of communication very imperfect. The native tribes were not road-makers, and the Romans had not been long enough in possession, nor had leisure been granted them to form the solid and straight lines of communication upon which, everywhere, their power was based. We have Roman roads in Strathearn, and I daresay a careful student of the district could walk every foot of the way from Ardoch to Perth along these roads—street-roads, they are called locally, as I discovered one night to my surprise on making inquiries as to the shortest route between the manses of Gask and Trinity-Gask. But these roads were not in existence when the Battle of Mons Grampus was fought. Much rough pioneering work had to be gone through ere it was possible to lay them down. Meantime, the respective positions of the Romans and Caledonians had changed somewhat. The tide of conquest did not remain at the high-water mark of Agricola's advance. The Roman garrisons were withdrawn from Strathearn and from Ardoch. The Wall of Hadrian, between the Solway and the Tyne, was substituted for the frontier chain of forts between the Forth and Clyde, and, in consequence, the native tribes kept pressing ever southward. Hadrian's Wall checked their progress, but their presence in ever-increasing numbers was a danger to the province. They had now come to be known as the Caledonii and the Meatae—the men of the hills and the men of the plains. At length the spirit of Rome revived in the Emperor Severus, who determined to revisit the scene of Agricola's early conquests. He came to Britain in 208 A.D., fully one hundred and twenty years after the Battle of Mons Grampus had been fought and won. He moved slowly, but did his work effectively. It was a costly process both in treasure and human life; but, from the point of view of permanent conquest, it was well done. Roads were formed, bridges built, and the habits of civilisation introduced into the wilds of Strathearn, and far away in the North. For, marching by way of Forfar, Kincardine, and Aberdeen, Severus reached the Moray Firth, and got from the Caledonians a cession of land to the north of the Tay. It has been conjectured that he returned south by way of Fortingall and Fendoch and Ardoch, where are Roman remains of a peculiar kind, of which no more satisfactory explanation can be given than that they mark the sites of his stations. Severus was borne on a litter in his northward march, frail and aged. He accomplished his purpose, but the undertaking was greater than his strength had warranted. He died at York in 211 A.D.
But to return to Agricola—to whom the honour belongs of opening up Strathearn. He had gone into winter quarters near Perth, after his autumn expedition to the Isla. All hesitation had vanished from the minds of his soldiers. They were impatient to try conclusions with the barbarian Caledonians; and so soon as the season permitted, the camp was broken up. They retraced their steps to the Isla, and found the enemy occupying the old position on the lower slopes of the Hill of Blair—battle-hill; probably so called in memory of the big fight now impending. It was a well-chosen position, showing no little military skill on the part of Galgacus, the Caledonian chief. From the foot of the hill a plain extended southward to the junction of the rivers. The Isla bounded the plain on the east, while a series of morasses, moors, and small lochs stretched to the west, in the direction of the Grampian range. Upon their defeat, the Caledonians made their escape this way. The Roman army boldly crossed the Isla this time, and began to throw up entrenchments. Traces of a rampart are to be seen extending from Meikleour on the Tay across country to the Isla. In connection with this a fort was constructed and a triangular bit of ground enclosed, capable of containing the whole force. The local name of the rampart is Cleaven Dykes, and all the while the Caledonians were gathering from all parts—from the distant Highlands and from the siege of the Strathearn forts. The Buzzard Dykes, on the lower slopes of the Hill of Blair, marks their position. At length they thought themselves strong enough to begin the attack. A defensive policy would have been wiser. But the concentrated power of a trained army—the very regularity of its motions always draws the attack of a less highly disciplined force. Probably the Caledonians deceived themselves into thinking that fear was the cause of the inaction of their opponents. It was not so. Agricola had come so far in order to fight, and his soldiers were impatient to be led against the enemy. They had gained confidence from the experience of the year before—they were hungry as wolves for the honour of victory. They knew that upon their valour depended the lives of their fellow-soldiers, who had been fighting for well nigh four years against tremendous odds away west in Strathearn. And when the Caledonians came on, Agricola promptly advanced to meet them, having 8000 auxiliaries in his first line, protected on the wings by 3000 cavalry. The legionaries were stationed behind these—veteran Roman soldiers, upon whose steadiness he could rely if there should come repulse and panic. The rampart at Meikleour was in the rear of the reserve force—to serve as a last defence if the worst happened. Agricola himself went to the front with the colours. As usual, the battle began with a discharge of missiles from a distance. The darts and stones flew thick, and all the while the Caledonians were edging away to right and left in the hope of surrounding the Romans. Agricola strained his thin line almost to breaking point, but his opponents had the advantage of numbers, and still pressed him. The danger of a gaping centre grew imminent. The crisis of the conflict came. Three Batavian and two Tungrian cohorts charged sword in hand. The issue was not long in doubt. The small shields and long swords of the Caledonians were ill-fitted to encounter the straight home-thrust of the finely-tempered blade, 19 inches in length, with which the Roman soldiers were armed. They wavered, and then the end came quickly. The whole line of the auxiliaries charged uphill and carried everything before them, and although the war chariots, armed with scythe-blades, were brought into action, they did more harm than good. The ground was rough, and unsuitable for the effective use of these murderous weapons of warfare. Their own men, now in hopeless confusion, were the chief sufferers from them. And although the Caledonian reserve succeeded in getting behind the Roman first line, they were promptly checked by a cavalry attack. It was never necessary to bring the Roman reserves of legionary soldiers into action. The fight was over, and the Caledonians sought safety in headlong flight among the morasses which stretched westward in the direction of the Grampian range.
Agricola did not push his advantage further. He was content with the victory he had gained, He could now hope that there would be peace in Strathearn, bringing with it the opportunity of extending the boundary of the Roman province to the Tay. His eager Roman spirit was planning other enterprises. He had seen the coast of Ireland from Kintyre, and doubtless courted the distinction of annexing it to the Empire. One can't help thinking what a pity it was that the opportunity of doing so was not given him. Had the distressful country got the benefit of the firm and civilising Roman rule, a happier history might have been hers. From his winter quarters behind the Firths of Forth and Clyde, Agricola sent his fleet to explore the distant northern parts. His sailors visited and took possession of the Orkney Islands—sighted a distant peak, which became the "Ultima Thule" of history; noted the peculiar feature of the West Coast of Scotland—the sea-lochs now so well known to the tourists of every land; circumnavigated the island till they reached the Trutulensian harbour—Dover, as we call it now; and then returned to their station in the Firth of Forth. It was not permitted to Agricola to turn the information thus acquired to practical use. His brilliant success in Scotland had excited the jealousy of the Emperor Domitian, and he was recalled under the pretence of appointing him to a higher command. The traces of him in Strathearn and elsewhere were speedily obliterated. The Roman province shrank to the wall of Hadrian between Tyne and Sol-way; civilisation was beaten back, and kept back for four generations.
