To oppose these invaders the English raised rapidly an army said to amount to 60,000 men. They had recalled John of Hainault and some cavalry which they had dismissed; and the young king of fourteen, burning with impatience to chastise the Scots, marched hastily towards the north. His progress, however, suffered some delay at York, from a violent quarrel which broke out between the English archers, and the foreign troops under John of Hainault. The archers, and especially those of Lincolnshire, who probably had an old feud with the natives of Flanders, displayed a dogged dislike to these troops, and in the streets of York they came actually to downright battle, and many men were killed on both sides. This difference quelled, if not settled, the English army moved on. Very soon they came in sight of burning farms and villages, which marked the track of the Scots. These Scots, however, themselves were nowhere visible, for they retreated with double the celerity with which the English, heavily loaded with baggage, could follow them. The Scots did not retreat directly north, but took, according to Froissart, their way westward amongst the savage deserts and "bad mountains and valleys," as he calls them, of Cumberland and Westmoreland. The English crossed the Tyne, trusting to cut off the homeward route of the enemy; but the utterly desolated condition of the country compelled them to recross that river, for no sustenance could be procured for the troops. After thus vainly pursuing this light-footed foe for some time, Edward, excessively chagrined in not being able to come up with them, or even to find them, offered a freehold worth £100 a year, and the honours of knighthood to any one who would bring him intelligence of the enemy. After the soldiers had undergone severe hardships and enormous fatigue wading through waters and swamps, a man, one Thomas of Rokeby, came riding hard to the camp and claimed the reward offered by the king. He said he had been made prisoner by the Scots, and that they had said they should be as glad to see the English king as he would be to see them. This was not very probable, as they might have waited for the king, which they had taken care not to do. They lay, however, at not more than three leagues distant.

The reason why the Scots had halted was visible enough when the English came up. They found them posted on the right bank of the Wear, where the river was deep and rapid, and there was no possibility of getting at them. Even could they cross the river, they must climb a steep hill in face of the enemy to attack them. Under these circumstances, Edward sent a challenge to the Scottish generals to meet him on a fair and open field, either by drawing back and allowing him to cross the river to attack them, or giving them the same option to cross over to his side. Douglas, annoyed at this proposal, advised to accept the challenge; but the more politic Moray refused, and replied to Edward that he never took the advice of an enemy in any of his movements. He reminded the king, as if to pique him to dare the unequal attempt of crossing in their faces, how long they had been in his country, spoiling and wasting at their pleasure. If the king did not like their proceedings, he added, insultingly, he might get over to them the best way he could.

Edward kept his ground opposite to them for three days; the Scots at night making huge fires along their lines, and all night long, according to the chronicler, "horning with their horns, and making such a noise as if all the great devils from hell had come there." In the daytime some of the most adventurous knights from the English army swam their strong horses across the river, and skirmished with the Scots—rather to show their gallantry than for any real effect. On the fourth morning it was found that the Scots had entirely decamped, and were discovered after awhile posted in a still stronger position higher up the river. Here Edward again sat down facing them, confidently hoping that they must be forced, from want of provisions, to come out and fight. As, however, they did not do this, the young king's patience became exhausted, and he desired to pass the river at all hazards, and come to blows with the Scots. This Mortimer would not assent to; and while lying, highly discontented with this restraint, on the bank of the river, Edward had a narrow escape of being taken prisoner.

The brave Douglas, being held back by Moray, as Edward was by Mortimer, from a general engagement, planned one of those heroic exploits in which he so much delighted. Making himself acquainted with the English password for the night, and taking an accurate survey of the English camp, he advanced, when it was nearly night, with 200 picked horsemen, silently crossed the river, at some distance above the English position, and then, as silently turning, made for the English camp. He found it carelessly guarded, and, seeing this, he rode past the English sentinels, as if he had been an English officer, saying, "Ha, St. George! you keep bad watch here!" Presently, he heard an English soldier say to his comrades, as they lay by a fire, "I cannot tell what is to happen here, but somehow I have a great fear of the Black Douglas playing us some trick."

"You shall have cause to say so," said Douglas to himself. When he had got fairly into the English camp, he cut the ropes of a tent with his sword, calling out his usual war-cry, "A Douglas! a Douglas! English thieves, ye are all dead men." His followers immediately fell upon the camp, cutting down the tents, overturning them, and killing the men as they started up to grasp their arms. Douglas, meanwhile, had reached the royal pavilion, and was as near as possible seizing the young king, but the chaplain, the chamberlain, and some of the king's household, being alarmed, stood boldly in his defence, and enabled him to escape under the canvas of the tent, though they lost their own lives. Douglas, being now separated from his followers, many of whom were killed, endeavoured to make good his retreat, but was in danger of being killed by a man who attacked him with a huge club. This man, however, he slew, and escaped in safety to his own camp; his party having, it is said, killed about 300 men.

Soon after this the Scots made an effectual retreat in the night by having beforehand cut a pathway through a great bog which lay behind them, and filling it with faggots; the road may still be seen in Weardale, and called from this cause the "Shorn Moss." The young king, on entering the evacuated place of encampment the next day, found nothing but six Englishmen tied to trees, with their legs broken, to prevent them from carrying any intelligence to their countrymen.

Edward, disgusted with his want of success, returned southward, and the Scots arrived in safety in their own country. On reaching York the English king disbanded his army. He then returned to London, highly dissatisfied, young as he was, with the state of things. Mortimer had usurped all power. Edward believed that from cowardice, or from some hidden motive, he had prevented him from taking ample vengeance on the Scots. At court he had set aside the whole of the royal council; consulted neither prince of the blood nor the nobles on any public measure, concentrating in himself, as it were, all the sovereign authority. He endowed the queen with nearly the whole of the royal revenues, and enjoyed them in her name. He himself was so besieged with his own party and parasites, that no one else could approach him, and all sorts and conditions of men now hated him as cordially as they had once done Gaveston.

Sensible of this public odium, Mortimer sought to make a peace with Scotland, to secure himself from attack on that side; and perhaps the king was not so far wrong in attributing his backwardness to attack the Scots to some private motive. Certain it is that in the following year, 1328, he made peace with Robert Bruce on terms which astonished and deeply incensed the whole nation. To give the greatest firmness to the treaty he proposed a marriage between Joan, or Joanna, the sister of Edward, then only seven years of age, and David, the son of Robert Bruce, then only five. That the Scots might accede promptly to this offer, he agreed to renounce the great principle for which the English nation had been so long contending—its claim of right to the crown of Scotland. These terms were, of course, eagerly accepted, and the treaty, to make all sure, was at once carried into effect. About Whitsuntide a Parliament was called together at Northampton which ratified the treaty, thus acknowledging the full independence of Scotland, and on the 22nd of July, the marriage was solemnised at Berwick, where Isabella had brought her daughter. This young bride was significantly called by the Scots "Joan Makepeace," and with her were delivered up many jewels, charters, &c., which had been carried away from Scotland by Edward I.

In return for these unlooked-for advantages, Bruce agreed to pay the King of England 30,000 marks as compensation for damages done in his kingdom.

Edward himself, a few months previous to this marriage of his sister, had received his long-affianced wife, Philippa of Hainault, who had been brought to this country by Isabella's champion, John of Hainault, the young queen's uncle. Philippa proved one of the best wives and queens the annals of England can boast.
