The bowmen had not long been a statutory force before they were called upon for active service. The defeat of the English by William Wallace at Cambuskenneth had summoned Edward from France to take the field in person against the Scots; and he met them on the field of Falkirk. The Scottish army consisted for the most part of infantry armed with pikes, not yet the long pikes of eighteen feet which they were to wield so gallantly under Gustavus Adolphus, but still a good and formidable weapon. Wallace drew them up behind a marsh in four circular battalions ringed in with stakes, posting his light troops, which were armed principally with the short-bow, in the intervals between them, and his one weak body of horse in rear. The English knights were formed as usual in column of three divisions, vanguard, battle and rearguard, and with them was a strong force of archers. Untrue to its old traditions, the English cavalry did not dismount, but galloped straight to the attack. The first division plunged headlong into the swamp (for the mediæval knight, in spite of a hundred warnings, rarely took the trouble to examine the ground before him), did no execution, and suffered heavy loss. The second division, under the Bishop of Durham, then skirted the swamp and came in sight of the Scottish horse. The Bishop hesitated and called a halt. "Back to your mass, Bishop," answered one contemptuous knight. His comrades charged, dispersed the Scottish cavalry, and drove away the archers between the pikemen; but the four battalions stood firm and unbroken, and the knights surged round them in vain. Then the king brought up the archers and the third division of horse. Pushing the archers forward, he held the cavalry back in support until an incessant rain of arrows had riddled the Scottish battalions through and through, and then hurling the knights forward into the broken ranks, he fairly swept them from the field. It was the old story, heavy fire of artillery followed by charges of cavalry, the training of the Scots as Hastings had been of the English, for the trial of Waterloo. [Sidenote: 1314.]
