At the head of the disinherited was Edward Balliol, the son of the deposed King John. Brought up in England, first under the care of his cousin, Earl Warenne, and afterwards in the household of the half-brothers of Edward II., Edward Balliol, who succeeded in 1315 to the French estates on which his father spent his latter years, divided his time between England and France. The forfeiture of his father still kept him out of Barnard Castle and the other Balliol lands in England. Young and warlike, poor and ambitious, with few lands and great pretensions, he never formally abandoned either the lordship of Galloway or the throne of Scotland. In 1330 he received permission to take up his quarters in England during pleasure. He soon associated himself with his fellow-exiles in a bold attempt to win back their patrimony. Chief among his followers were three titular Scottish earls, closely related by intermarriage, each of whom was also a baron of high rank in England. Of these the French-born Henry of Beaumont, kinsman of Eleanor of Castile, and brother of Bishop Louis of Durham, was the oldest and most experienced. As the husband of a sister of the last of the Comyn Earls of Buchan, he posed as the heir of the greatest of the Scottish houses which had paid the penalty of its opposition to King Robert, and was summoned to the English parliament as Earl of Buchan. Beaumont's great-nephew, the young Gilbert of Umfraville, lord of Redesdale, was a grandson of another Comyn heiress, and his ancestors had inherited in the middle of the thirteenth century the ancient Scottish earldom of Angus, though they also had incurred forfeiture for their adhesion to the English policy. David of Strathbolgie, Earl of Athol, had a better right to be called a Scot than Umfraville or Beaumont. But his father abandoned Bruce, and was driven into England, where he held the Kentish barony of Chilham, and sat in the English parliament under his Scottish title. The younger Athol was son-in-law to the titular Earl of Moray, and all three kinsmen were bound by common interests to embrace the policy of Edward Balliol. Many lesser men associated themselves with the three earls and the claimant to a throne. Nearly every nobleman of the Scottish border made himself a party to a scheme of adventure which had its best parallels in the Norman invasions of Wales and Ireland.

The object of the disinherited was to raise an army and prosecute their Scottish claims by force. Edward III. gave them no open countenance, and took up an ostentatiously correct attitude. He solemnly forbade all breach of the peace, and prevented the adventurers from adopting the easy course of marching from England to an open attack on Scotland. No obstacles, however, were imposed to hinder their raising a small but efficient army of 500 men-at-arms and 1,000 archers. Mercenaries, both English and foreign, were hired to supplement their scanty numbers, and among those who took service with them was a young gentleman of Hainault, Walter Manny, whose father had a few years before perished in the service of Edward II. in Gascony, and who had first come to England in the service of his countrywoman, Queen Philippa. Ships were collected in the Humber, and on the last day of July, 1332, the disinherited and their followers sailed from Ravenspur on a destination which was officially supposed to be unknown. A week later, on August 6, they landed at Kinghorn in Fife.

Scotland was singularly unready to meet invasion. The regent Moray had died a few weeks earlier, and his successor, Donald, Earl of Mar, incompetent to carry on his vigorous policy, had perhaps already been intriguing with the adventurers. The only resistance to Balliol's landing, made by the Earl of Fife, was altogether unsuccessful. The little army established itself easily in the enemies' territory, and, after two days' rest at Dunfermline, advanced over the Ochils towards Perth. The regent had by that time gathered together an imposing army. As the invaders approached Strathearn on their way northwards, they found Mar encamped on Dupplin Moor, on the left bank of the Earn, and holding in force the only bridge available for crossing the river. There was some parleying between the two hosts. "We are sons of magnates of this land," declared the disinherited to Mar. "We are come hither with the lord Edward of Balliol, the right heir of the realm, to demand the lands which belong to us by hereditary right." Mar returned a warlike answer to their words, and both armies made preparation for battle.

The disinherited, though few in number, were well trained in warfare, and from the beginning showed capacity to out-general the unwieldy host and feeble leader opposed to them. At sunset, some of their forces crossed the Earn by a ford which the Scots had neglected to guard, and falling upon an outlying portion of the enemies' camp, where the infantry were quartered, slaughtered the surprised Scots at their leisure. Luckily for Mar, the whole of his knights and men-at-arms were far away, uselessly watching the bridge, over which they had expected the disinherited to force a passage. Thus saved from the night ambuscade, the kernel of the Scottish army prepared next morning, August 12, to attack the disinherited. Puffed up by the memory of Bannockburn and the consciousness of superior numbers, they marched to battle as if certain of victory. All fought on foot, and the men-at-arms were drawn up in a dense central mass, supported at each side by wings. The disinherited were sufficiently schooled in northern warfare to adopt the same tactics. Save for a few score of horsemen in reserve, their heavily armed troops, leaving their horses in the rear, formed a compact column after the Scottish fashion. But archers were distributed in open order on the right and left flanks, with both extremities pushed forward, so that they formed the horns of a half-moon. Then the Scots advanced to the charge, and both sides joined in battle. The irresistible weight of the Scottish main phalanx forced back the little column of the disinherited, and for a moment it looked as if the battle were won. Meanwhile the archers on the flanks poured a galling shower on the collateral Scottish columns. The unvisored helmets of the Scots made them an easy prey to the storm of missiles, and they were driven back on to the main body. By this time the disinherited had rallied from the first shock; and still the deadly hail of arrows descended from right and left, until the whole of the Scottish army was thrown into panic-stricken disorder. Escape was impossible for the foremost ranks by reason of the closeness of their formation. At last, the rear files sought safely in flight, and were closely pursued by the victors, mounted on their fresh horses. A huge mass of slain, piled up upon each other, marked the place of combat. As at Bannockburn, the small disciplined host prevailed, but discipline was now with the English and numbers only with the Scots.[1]

[1] The significance of the battle of Dupplin was first pointed out by Mr. J.E. Morris in Engl. Hist. Review, xii. (1897), 430-31.

The victory of Dupplin Moor was for the moment decisive. Balliol occupied Perth, and received the submission of many of the Scottish magnates, among them being that Earl of Fife who first opposed his landing. A few weeks later, on September 24, Balliol was crowned King of Scots at Scone by the Bishop of Dunkeld. It was a soldier's coronation, and the magnates sat at the coronation feast in full armour, save their helmets. The disinherited then received the lands for which they had striven; and thereupon quitted the new king, either to secure their estates or to revisit their property in England. But the Scots, of no mind to receive a king from the foreigner, chose a new regent in Sir Andrew Moray, son of the companion of Wallace; and prepared to maintain King David. On December 16, Balliol was surprised at Annan by a hostile force under the young Earl of Moray, son of the late regent, and by Sir Archibald Douglas. His followers were cut off, his brother was slain, and he himself had the utmost difficulty in effecting his escape to England. He had only reigned four months.

During Balliol's brief triumph, Edward III. had declared himself in his favour. Debarred by the treaty of Northampton from questioning the independence of King David, he was able to make what terms he liked with David's supplanter. In November a treaty was drawn up at Roxburgh, by which Balliol recognised the overlordship of Edward, and promised him the town, castle, and shire of Berwick. In return for these concessions, Edward III. acknowledged his namesake as lawful King of Scots. When, a few weeks later, his new vassal appeared as a fugitive on English soil, Edward had no longer any scruples in openly supporting him in an attempt to win back his throne. In the spring of 1333, Balliol and the disinherited once more crossed the frontier in sufficient force to undertake the siege of Berwick. The border stronghold held out manfully, but the Scots failed in an attempt to divert the attention of the English by an invasion of Cumberland. After Easter, Edward III. went in person to Berwick, and devoted the whole resources of England to ensuring its reduction. The siege lasted on until July, when the garrison, at the last gasp, offered to surrender, unless the town were relieved within fifteen days. The Scots made a great effort to save Berwick from capture, and the English king was forced to fight a pitched battle, before he could secure its possession.

On July 19 Edward, leaving a sufficient portion of his army to maintain the blockade of Berwick, took up a position with the remainder on Halidon Hill, a short distance to the west of the town. The lessons of Bannockburn, Boroughbridge, and Dupplin were not forgotten, and the English host was arranged much after the fashion which had procured the first victory of the disinherited. Knights and men-at-arms sent their horses to the rear and, from the king downwards, all, save a small reserve of horse, prepared to fight on foot. Edward divided his forces into three lines or "battles," each of which consisted of a central column of dismounted heavily armed troops, flanked by a right and a left wing of archers in open order, John of Eltham and the titular Earl of Buchan commanded the right battle, the king the centre, and Edward Balliol the left. The Scots still employed the traditional tactics which had failed so signally at Dupplin. Sir Archibald Douglas led his followers up the slopes of the hill in three dense columns. But a pitiless rain of arrows spread havoc among their ranks, and there were no answering volleys to disturb their foes. The battle was won for the English almost before the two lines had joined in close combat. It was only on Edward's right that the Scots were strong enough to push home their attack. On the centre and left, the English easily drove the enemy in panic flight down the slopes which they had ascended so confidently. The pursuit was long and bloody; few were taken prisoners, but many were slain or driven into the sea. Seven Scottish earls were believed by the English to have fallen, while the victors lost one knight, one squire, and a few infantry soldiers. Thus, for a second time the tactics, which had served the Scots so well in the defensive fight of Bannockburn, failed in offence to secure victory for them. The experience of this day completed the evolution of the new English battle array of men-at-arms fighting on foot and supported by wings of archers, which was soon to excite the wonder of Europe, when its possibilities were demonstrated on continental fields.

Next day Berwick opened its gates, and was handed over to the English, according to the treaty of Roxburgh, to be for the rest of its history an English frontier town. Edward Balliol again conquered Scotland as easily as he had done on the former occasion, and far more effectually. It was no longer possible for the few remaining champions of the house of Bruce to safeguard the person of the little king and queen. David and Joan were accordingly sent off to France, where they were to grow up as good friends of King Philip. But Balliol had so clearly regained his throne through English help that he was no longer an independent agent. No sooner was his conquest assured than he was forced not only to confirm the surrender of Berwick, but to yield up the whole of south-eastern Scotland as the price of the English assistance. The depth of his humiliation was sounded when, in the treaty of Newcastle, June 12, 1334, Edward, King of Scots, granted Edward, King of England, lands worth two thousand pounds a year in the marches of Scotland, and in part payment thereof yielded up to him, besides Berwick and its shire, the castle, town, and county of Roxburgh, the forests of Jedburgh Selkirk, and Ettrick, the town and county of Selkirk, and the towns, castles, and counties of Peebles, Dumfries, and Edinburgh. Of these Dumfries then included the Stewartry of Kirkcudbright, while the shire of Edinburgh took in the constabularies, the modern shires, of Haddington and Linlithgow. Thus the whole of Lothian, the whole of the central upland region, and Balliol's own inheritance of Galloway east of the Cree were directly transferred to the English crown, and were divided into sheriffdoms, and officered after the English fashion. On June 18 Balliol personally performed homage for so much of Scotland as Edward chose to leave him. The wrongs of the disinherited had been the means of re-opening the whole Scottish question, and Edward III. seemed assured of a position as supreme as that which had once been held by Edward I.

It was always easier in the Middle Ages to conquer a country than to keep it. And the experience of forty years might well have convinced Englishmen that no land was more difficult to hold than the stubborn and impenetrable northern kingdom, with its strenuous population, ever willing to cry a truce between local feuds when there was an opportunity of uniting against the southerners. Edward overshot his mark in grasping too eagerly the fairest portions of Balliol's realm. He needed for his policy a Scottish king, strong enough to maintain himself against his subjects, and loyal enough to remain true to the English connexion. Any faint chance of Balliol occupying such a position was completely destroyed by his studied humiliation. Henceforward the King of Scots, who had fought so well at Dupplin and Halidon, was but a pawn in Edward's game. Hated by the Scots as the betrayer of his country, distrusted by the English who henceforth spied his actions and commanded his armies in his name, the gallant victor of Dupplin lost faith in himself and in his cause. After all, he was his father's son, and in no wise capable of bearing adversity and indignity with equanimity. His helplessness soon proved the worst obstacle in the way of the success of Edward's plans. Even with the aid of a large Scottish party, Edward I. had failed to bring about the subjection of Scotland. It was clearly impossible for his grandson to succeed in the same task when all Scotland was united against him, and braced to action by a series of glorious memories.
