King Edward had raised two armies: one was to march to Guienne, and the other to Flanders, to help the Count Guy, who was anxious to avenge his injuries on King Philip. Edmund, King Edward's brother, had died in Guienne. The king himself reckoned upon commanding the expedition in Flanders. He summoned to Salisbury Humphrey Bohun, earl of Hereford and constable of England, and Roger Bigod, earl of Norfolk, field-marshal, to entrust to them the command of the army of Guienne. Both replied that their offices compelled them to remain near the king's person during the war, and that they would not proceed to Guienne without him. "By the Lord God Almighty, my lord earl!" cried Edward, addressing himself to Bigod, "You shall go, or you shall be hanged." "By the Lord God Almighty, Sire king," replied the proud baron, calmly, "I shall not go, neither shall I be hanged." And both retired to their estates, immediately followed by thirty bannerets and by fifteen hundred knights, who everywhere created an opposition to the levying of the taxes.

The king was in an awkward position. He convoked in London a popular assembly, having taken care first of all to become reconciled with the Archbishop of Canterbury, Winchelsea, who had been the prime mover in the resistance of the clergy, and had found himself deprived of all his revenues in consequence; then, accompanied by the prelate, the Earl of Warwick, and Prince Edward, the king appealed directly to the people, assuring them that nothing was more disagreeable to him than to impose heavy burdens upon his well-beloved subjects; but that he had been compelled to do so in order to defend them against the Scotch, the Welsh, and the French. "I am now going to expose myself for you to the risks of war," said he; "if I return alive, I will repay you for everything; if I should die, there is my son: place him upon the throne, and his gratitude will reward your fidelity." The king was weeping, and all those who were present were profoundly touched. Prince Edward was declared regent amid public acclamation; the Archbishop of Canterbury was nominated as his adviser, and the king marched towards the coast. He had only arrived at Winchester, when he was stopped, on the 12th of August, by a remonstrance from the prelates, the earls, the barons, and the commoners of England, declaring that they were not obliged to accompany him into Flanders, their ancestors not having served the kings of England in that country; and they added that, even were they so disposed, the poverty to which they had been reduced did not allow them to do so. "The king," they said, "had already violated on several occasions the charters which he had solemnly ratified; his 'evil toll' was intolerable, and his absence was about to leave the country a prey to the invasions of the Scotch and the Welsh." The king made an evasive reply to this declaration; reckoning upon the affection of the common people, he made sail with the troops who remained with him, and disembarked at Sluys towards the end of August.

Scarcely had Edward left the coasts of England when Bigod and Bohun entered London, on the 24th of August, at the head of considerable forces. The strictest discipline prevailed in the ranks of their followers. They went straight to the treasury, and deposited their complaints against the arbitrary exactions and the violations of Magna Charta committed by the king; then, proceeding to Guildhall, they exhorted the citizens of London to maintain their rights. The young regent, being alarmed, convoked a Parliament, which abolished the impost upon wool, and decreed that no tax whatever should in future be raised without the consent of the bishops, peers, citizens, and freemen of the kingdom, and that the king should not seize upon any goods without the authority of the owners. Orders were sent out to read the Magna Charta in all the churches once a year, under pain of excommunication against those who should endeavor to prevent it. This law was to be proclaimed every Sunday in all the churches.

The act, signed in London, was sent to Ghent, where King Edward was at the time. They demanded that it should be ratified. The barons undertook to join the king in Flanders, or to march against Scotland, where the people had again risen, according to his pleasure. During three days, the pride of King Edward resisted; at length he signed the document, promising himself to make all his concessions void afterwards. As soon as they were secure in their victory, the barons set out for Scotland.

Edward needed the support and good will of his English subjects, for he had gained but little success in Flanders. After having with difficulty quelled the violent rivalries which had occurred in his fleet between the sailors of the different ports, he had found a great number of Flemish towns occupied by the French, supported by a party powerful in the country itself. The Count Guy had again fallen into the hands of the King of France. The Flemish and English would often engage in struggles against each other, after having fought together against the French; Edward's foreign allies, the Emperor, the Duke of Austria, and the Duke of Brabant, sent no help, believing they had done their share in receiving the subsidies of England. King Edward listened to the overtures of Pope Boniface VIII., who was endeavoring to re-establish peace. He left Guy of Flanders in prison, where the latter, as well as his daughter, afterwards died. He affianced his son Edward to Isabel of France, thus laying the foundation of the misfortune of his lifetime, and himself married Princess Margaret, who was then seventeen years of age, contenting himself with recovering Aquitaine, while Guienne still remained in the hands of Philip the Fair. Peace being thus concluded, Edward started on his return to his kingdom, where the position of affairs imperatively required his presence.

The great Scotch noblemen had taken the oath of allegiance to the King of England, but the less powerful ones had not had the honor of accomplishing that act of submission. Sir Malcolm Wallace, of Ellerslie, had not taken the oath, nor had his second son, William Wallace, who was already outlawed for the murder of an English soldier in consequence of a dispute. He had lived since then in the mountains; but, having one day appeared at the market in Lanark, he was insulted by an Englishman, whom he killed. He found a friendly shelter, and contrived to escape; but the house which had protected him was burnt, and the mistress of it lost her life. Wallace swore to wreak a terrible revenge upon the English.

Soon, all the adventurers, outlaws, and bold spirits, weary of subjection, rallied round Wallace. At the moment when King Edward started for Flanders, the Scottish leader had already become a dangerous partisan, attacking the English when he met them in small numbers, and plundering the country under their authority. His forces were increasing in number; many noblemen had joined him, and were raising their standards in favor of John, king of Scotland. A certain number of powerful noblemen followed them. Robert Bruce himself, grandson of him who had contested the crown against Baliol, had come over to the national party. "The Pope will absolve me from all the oaths which I have involuntarily sworn in favor of King Edward," said the future deliverer of Scotland. The Earl of Surrey was raising forces in the southern part of the kingdom.

When the two armies came in sight of each other, near the town of Irvine, in the county of Ayr, they were about equal in numbers; but the English troops were well drilled and obedient to a single general; Wallace's army was disorderly, divided, led by rival chiefs, and little disposed to admit the superiority of an outlaw of low origin. No encounter took place. On the 9th of July, the great Scotch noblemen laid down their arms and tendered their submission to King Edward. One baron alone. Sir Andrew Moray of Bothwell, remained faithful to the national party; but Wallace took with him a large number of vassals of the noblemen who had surrendered, and his raids upon the territory occupied by the English became bolder and bolder every day.
