It is interesting to note that Edward made an effort even then for the constitutional union of the two countries which had so honourably lost and won the day at Falkirk, but he was four centuries before his time. The war continued with varying fortune during the ensuing years. The maker of the English archers died, and under his feeble son the English army learned at Bannockburn an ignominious lesson in tactics. The Scotch army, forty thousand strong, was composed principally of pikemen, who were drawn up, as at Falkirk, in four battalions, with the burn in their front and broken ground on either flank. Their cavalry, numbering a thousand, a mere handful compared to the host of the English men-at-arms, was kept carefully in hand. Edward opened the action by advancing his archers to play on the Scottish infantry, but omitted to support them; and Bruce, seeing his opportunity, let loose his thousand horse on their flank and rolled them up in confusion. The English cavalry then dashed in disorder against the serried pikes, failed, partly from want of space and partly from bad management, to make the slightest impression on them, and were driven off in shameful and humiliating defeat. So the English learned that their famous archers could not hold their own against cavalry without support,[13] and they took the lesson to heart. The old system of dismounting the men-at-arms had been for the moment abandoned with disastrous results; the man who was to revive it had been born at Windsor Castle just two years before the fight. [Sidenote: 1327.] [Sidenote: 1333.] Thirteen years later this boy ascended the throne of England as King Edward the Third, and almost immediately marched with a great host against the Scots. The campaign came to an end without any decisive engagement, but on the one occasion when an action seemed imminent, the English men-at-arms dismounted and put off their spurs after the old English fashion. Peace was made, but only to be broken by the Scots, and then Edward took his revenge for Bannockburn at Halidon Hill. The English men-at-arms alighted from their horses, and were formed into four battalions, each of them flanked by wings of archers, the identical formation adopted two centuries later for the pikemen and musketeers. The Scots, whose numbers were far superior, were also formed on foot in four battalions, but without the strength of archers. "And then," says the old historian,[14] "the English minstrels blew aloud their trumpets and sounded their pipes and other instruments of martial music, and marched furiously to meet the Scots." The archers shot so thick and fast that the enemy, unable to endure it, broke their ranks, and then the English men-at-arms leaped on to their horses for the pursuit. The Scotch strove gallantly to rally in small bodies, but they were borne down or swept away; they are said to have lost ten thousand slain out of sixty thousand that entered the battle.
