Such were the circumstances under which Edward entered on the expedition which terminated with so little success to the English arms. He landed at Sluys in the month of August, and immediately on his arrival quarrels broke out among the sailors of the fleet, who came from different seaports, and between whom there had been long-standing feuds. Such was the extent to which these animosities were carried, that a regular engagement took place between the mariners of Yarmouth and those of the Cinque Ports, and twenty-five ships belonging to the former were burnt. It is related that, during the conflict, three of their largest ships, one of which carried the royal treasure, were taken possession of and conveyed out to sea.

While such was the condition of the British navy at this period, the land troops were occupied with similar quarrels and disorders. Among the allies of Edward there was little more unity. The cities of Flanders, rivals in wealth and power, regarded each other with a jealousy which threatened the most serious dissensions. Among the various factions were some who adhered to Philip of France, and their numbers were greatly increased when that king marched into the country at the head of an imposing force of 60,000 men. The French gained a victory over the Flemings at Furnes, and obtained possession of a number of their chief towns.

Damme had been occupied by Philip, who was compelled to retire before the English forces, and Edward then advanced into the country, making an unsuccessful attack on Bruges, and going into winter quarters at Ghent. Here the most deadly quarrels broke out between the English troops and the townspeople; and in a riot which took place in the town 700 of the English were killed. Every effort was made by the king and Count Guy to repress these tumults; but the feud continued without abatement, and effectually prevented any combined movements against the enemy.

Such was the position of affairs in the winter of 1297, when proposals for a truce having been made by Philip, they were readily accepted, and the English king returned to his own country. Edward had spent large sums of money in this expedition, which had ended in a manner wholly unworthy of his fame and his resources. But the humiliation of the king had not been confined to the non-success of his arms; he was compelled to give his assent to various reforms introduced by his barons, and to add confirmations of those charters which checked the abuse of arbitrary power. Early in the preceding year the constable of the kingdom, with the earl marshal and many other of the nobles, interposed in defence of the privileges of Parliament, and forbade the officers of the exchequer, in the names of the barons of the kingdom, to collect certain taxes which had been laid on by the king without the consent of the national representatives. The citizens of London were allied with the barons in this measure, and Edward found himself at length compelled to submit. From the city of Ghent, where he was then staying, he sent instructions to this effect to the council of regency, some of whom were known to favour the demands of Parliament; and at the same place he granted a new confirmation of the two charters, and also of an important enactment, by which it was declared that no impost should be levied without the consent of the peers spiritual and temporal, the knights burgesses, and other freemen of the realm.

Such concessions as these were not made by Edward without great reluctance, and his annoyance at the restrictions thus placed upon him was clearly shown soon after his return to England. His barons, however, were determined that the statutes should not be evaded, and a Parliament having been summoned at York, the king was called upon to give a solemn ratification of the charters he had granted. Edward excused himself at that time under the plea that he was on his way to chastise the Scots; but he gave his promise to do what was desired of him on his return, and the Bishop of Durham and three barons made oath in his name to that effect.

On his return from Scotland, Edward met his parliament, which was assembled in March, 1299, at Westminster. He now endeavoured by every means in his power to gain time, and when closely pressed, he quitted London, as it were by stealth. The barons, however, were not to be thus defeated, and having followed him, and urged the fulfilment of his solemn obligations Edward found himself compelled to assent. By an extraordinary act of craft, however, he took measures to evade the provisions of the document by adding a clause at the end, "saving the rights of the crown," which destroyed the value of the concession, and subverted the meaning of what had gone before. The cunning of the king had, in this instance, overreached itself. With few exceptions, the barons rose up in indignation, and quitted the assembly and the city, with their retainers. Edward now proposed, as he had done before, to secure the goodwill of the people; and to this end he directed the sheriffs of London to call a meeting of the citizens, and to read to them the new confirmation of the charters. The people assembled in large numbers in St. Paul's Churchyard, and listened attentively. It appears that they possessed more intelligence than the king gave them credit for, since, after having applauded the earlier clauses, they no sooner heard the last, than they gave every demonstration of indignation, and proved that they fully comprehended its unworthy purport. The king now perceived that the country was unanimously against him; and having called his Parliament once more together, he threw out the obnoxious clause, and granted all the concessions that had been demanded. There was, in fact, no alternative, if Edward desired to maintain his position and authority. Four years later, the king sent to the reigning Pope, Clement V., to request a dispensation absolving him from the oaths he had taken, and to which he said he had been driven by a traitorous conspiracy. The Pope, however, evaded the request; and when the further solicitations of Edward failed to produce a more decided effect, he found himself compelled to respect those grants which he had made law.

Philip the Fair, who was inferior to Edward in warlike accomplishments, was his equal in craft and cruelty. After the English king quitted Flanders, in 1297, he had no opportunity of conducting further measures of importance in that country, which during the succeeding years was overrun by the French troops. In the year 1302 the Flemings rose against their oppressors, and gained a complete victory over them at Courtrai. That the "rabble of Flemings," as the French called them, should thus overcome the chivalry of France, was a disgrace not to be endured; but while the nobles were panting for a knightly vengeance, their king was planning a safer and bloodier retaliation. For some time previously Edward had determined to abandon his ally, the Count of Flanders, and to regain possession of Guienne from the King of France by treaty. The Pope was now appealed to, and he proposed an alliance of marriage between the two kings. Edward, who was now a widower, was to marry Margaret, the sister of Philip, and the Prince of Wales was to marry Isabella, the daughter of the French king. Such an alliance had already been contemplated with satisfaction by the negotiators. It is true that there were difficulties in the way. Edward had sworn solemnly to marry his son to Philippa, daughter of the Count of Flanders; he had also pledged his honour that he would never make truce with the French king without the entire concurrence of his ally. But these obstacles served only to delay the progress of the negotiations for a few months. Edward broke off his solemn engagements abroad as readily as he threw aside his oaths at home; and in September, 1299, the double marriage took place, the son being contracted to Isabella by proxy at the same time that his father was married to Margaret.

A peace between France and England necessarily attended the conclusion of this alliance; and it was agreed that injuries remaining unredressed on either side should be compensated for, and that the possession of Guienne should be settled by negotiation; pending which, Philip gave several towns in Gascony to be held as security by the Pope. In these arrangements the French king entirely disregarded his alliance with the Scots; and neither in this treaty, nor at its subsequent ratification, were they in any way mentioned. On the 20th of May, 1301, the treaty was formally concluded. Edward regained possession of the province of Guienne, and, in return, he gave up the Flemings into the hands of their enraged enemies. A few months later, the French barbarously revenged themselves for their former defeat at Courtrai, by attacking the Flemish peasants of the district of Lille, and putting them to death in what was a massacre rather than a battle. A year previously, Count Guy of Flanders had fallen into the hands of Philip, by whom the noble old man was subjected to cruelty, which soon resulted in his death. He died in his prison at Compiègne at the age of eighty-one.

Having concluded peace with France, Edward immediately turned his attention to Scotland. Notwithstanding the decisive victory of Falkirk, and the apparent surrender of the cause by Wallace, the subjugation of that country was far from being effected. There still existed in every quarter a determined spirit of hostility to the English, kept alive by the memory of the recent defeats, and not less so of the preceding triumphs. In 1300 the king made an incursion into Annandale, which he laid waste, and received the speedy submission of Galloway. The Scots, who were making zealous efforts to secure assistance from foreign courts, thought it prudent to make a truce, which was ratified in November at Dumfries, and was to continue in force till the summer of the following year. Their applications, however, to the Continental courts received but little encouragement. Philip of France, as was to be expected after so recent a pacification with the English monarch, rejected their suit. The only person who seems to have responded to their appeal was Pope Boniface VIII. He wrote a letter to Edward, entreating him to put an end to his ravages and oppressions in Scotland, and adducing a great number of historical proofs of the ancient and unquestionable independence of that kingdom—proofs with which, no doubt, the Scottish envoys had taken care to supply him. With a singular inconsistency, however, the Pope concluded his letter by asserting that Scotland was, in reality, a fief of the Holy See. This claim, never before heard of, and in utter contradiction to the whole tenor of the Papal brief, called forth the most earnest reply from Edward, who set about and constructed a catalogue of sovereign claims on Scotland, from the fabled age of Brutus, the Trojan, who, he asserted, founded the British monarchy in the days of Eli and Samuel, down to those of King Arthur, the hero of romance rather than of history; concluding with the full and absolute homage done by William of Scotland to Henry II. of England; taking care to omit all mention of the formal abolition of that deed by Richard Cœur-de-Lion, who had frankly pronounced it an extorted one, and therefore invalid. This royal epistle was seconded by a very spirited remonstrance from 104 barons, assembled by the king's command at Lincoln, who proudly maintained the temporal independence of both the kingdoms of Scotland and England of the see of Rome; declaring that they had sworn to defend the king's prerogatives, and that at no time would they permit them to be questioned.
