The Scottish revolt had become so formidable that Edward was compelled to abandon his unfruitful Flemish campaign; he patched up an unsatisfactory truce with the king of France, which left four-fifths of his lost Gascon lands in the power of the enemy, and returned to England in the spring of 1298. In July he invaded Scotland at the head of a formidable army of 15,000 men, and on the 22nd of that month brought Wallace to action on the moors above Falkirk. The steady Scottish infantry held their own for some time against the charge of the English men-at-arms. But when Edward brought forward his archers to aid his cavalry, as William I. had done at Hastings, Wallace's columns broke up, and a dreadful slaughter followed. The impression made on the Scots was so great that for some years they refused to engage in another pitched battle. But the immediate consequences were not all that might have been expected. Edward was able to occupy many towns and castles, but the broken bands of the insurgents lurked in the hills and forests, and the countryside as a whole remained unsubdued. Wallace went to France to seek aid from King Philip, and his place was taken by John Comyn, lord of Badenoch, a nephew of Baliol, who was a more acceptable leader to the Scottish nobles than the vanquished knight of Falkirk. Edward was detained in the south for a year, partly by negotiations with France, partly by a renewed quarrel with his parliament, and during his absence Comyn recovered Stirling and most of the other places which had received English garrisons. It was not till 1300 that the king was able to resume the invasion of Scotland, with an army raised by grants of money that he had only bought by humiliating concessions to the will of his parliament, formulated in the _Articuli super cartas_ which were drawn up in the March of that year. Even then he only succeeded in recovering some border holds, and the succeeding campaign of 1301 only took him as far as Linlithgow. But in the following year his position was suddenly changed by unexpected events abroad; the king of France became involved in a desperate quarrel with the pope, and at the same moment his army received a crushing defeat before Courtrai at the hands of the Flemings. To free himself for these new struggles Philip made up his mind to conclude peace with England, even at the cost of sacrificing his conquests in Gascony. Bordeaux had already revolted from him, and he gave up the rest of his ill-gotten gains of 1294 by the treaty of Paris (May 20, 1303). Edward again invades Scotland, 1303.
