The English men-at-arms had succeeded in overthrowing the Scots, against whom they had charged, and had pursued them some distance; but upon drawing rein and turning to rejoin the army, they found the aspect of affairs changed indeed. The troops left at the head of the bridge were overthrown and destroyed. The royal banner and that of Surrey were down, and the bridge in the possession of the enemy. The men-at-arms charged back and strove in vain to recover the head of the bridge. The Scots fought stubbornly; those in front made a hedge of pikes, while those behind hurled darts and poured showers of arrows into the English ranks. The greater proportion of the men-at-arms were killed. One valiant knight alone, Sir Marmaduke de Twenge, with his nephew and a squire, cut their way through the Scots, and crossed the bridge. Many were drowned in attempting to swim the river, one only succeeding in so gaining the opposite side.
The men-at-arms defeated, Wallace and the chosen band under him, who had been engaged with them, joined those who were attacking the English and Welsh, now cooped up in the promontory. Flushed with the success already gained the Scots were irresistible, and almost every man who had crossed was either killed or drowned in attempting to swim the river. No sooner had he seen that the success in this quarter was secure than Wallace led a large number of his followers across the bridge. Here the English, who still outnumbered his army, and who had now all the advantage of position which had previously been on the side of the Scots, might have defended the bridge, or in good order have given him battle on the other side. The sight, however, of the terrible disaster which had befallen nearly half their number before their eyes, without their being able to render them the slightest assistance, had completely demoralized them, and as soon as the Scotch were seen to be crossing the bridge they fled in terror. A hot pursuit was kept up by the fleet footed and lightly armed Scots, and great numbers of fugitives were slain.
More than 20,000 English perished in the battle or flight, and the remainder crossed the Border a mere herd of broken fugitives.
The Earl of Surrey, before riding off the field, committed the charge of the Castle of Stirling to Sir Marmaduke de Twenge, promising him that he would return to his relief within ten weeks at the utmost. All the tents, wagons, horses, provisions, and stores of the English fell into the hands of their enemies, and every Scotch soldier obtained rich booty.
Cressingham was among the number killed. It was said by one English historian, and his account has been copied by many others, that Cressingham's body was flayed and his skin divided among the Scots; but there appears no good foundation for the story, although probably Cressingham, who had rendered himself peculiarly obnoxious and hateful to the Scots, was hewn in pieces. But even were it proved that the ill story is a true one, it need excite no surprise, seeing the wholesale slaying, plundering, and burning which had been carried on by the English, and that the Scottish prisoners falling into their hands were often mutilated and tortured before being executed and quartered. The English historians were fond of crying out that the Scotch were a cruel and barbarous people whenever they retaliated for the treatment which they suffered; but so far from this being the case, it is probable that the Scotch, before the first invasion of Edward, were a more enlightened and, for their numbers, a more well-to-do people than the English. They had for many years enjoyed peace and tranquillity, and under the long and prosperous reign of Alexander had made great advances, while England had been harassed by continuous wars and troubles at home and abroad. Its warlike barons, when not engaged under its monarchs in wars in Wales, Ireland, and France, occupied themselves in quarrels with each other, or in struggles against the royal supremacy; and although the higher nobles, with their mailclad followers, could show an amount of chivalrous pomp unknown in Scotland, yet the condition of the middle classes and of the agricultural population was higher in Scotland than in England.
Archie, as one of the principal leaders of the victorious army, received a share of the treasure captured in the camp sufficient to repay the money which he had had for the strengthening of the Castle of Aberfilly, and on the day following the battle he received permission from Sir William to return at once, with the 250 retainers which he had brought into the field, to complete the rebuilding of the castle. In another three months this was completed, and stores of arms and munition of all kinds collected.
Immediately after the defeat at Stirling Bridge, King Edward summoned the Scottish nobles to join Brian Fitzallan, whom he appointed governor of Scotland, with their whole forces, for the purpose of putting down the rebellion. Among those addressed as his allies were the Earls Comyn of Badenoch, Comyn of Buchan, Patrick of Dunbar, Umfraville of Angus, Alexander of Menteith, Malise of Strathearn, Malcolm of Lennox, and William of Sutherland, together with James the Steward, Nicholas de la Haye, Ingelram de Umfraville, Richard Fraser, and Alexander de Lindsay of Crawford. From this enumeration it is clear that Wallace had still many enemies to contend with at home as well as the force of England. Patrick of Dunbar, assisted by Robert Bruce and Bishop Anthony Beck, took the field, but was defeated. Wallace captured all the castles of the earl save Dunbar itself, and forced him to fly to England; then the Scotch army poured across the Border and retaliated upon the northern counties for the deeds which the English had been performing in Scotland for the last eight years. The country was ravaged to the very walls of Durham and Carlisle, and only those districts which bought off the invaders were spared. The title which had been bestowed upon Wallace by a comparatively small number was now ratified by the commonalty of the whole of Scotland; and associated with him was the young Sir Andrew Moray of Bothwell, whose father had been the only Scotch noble who had fought at Stirling, and it is notable that in some of the documents of the time Wallace gives precedence to Andrew Moray.
They proceeded to effect a military organization of the country, dividing it up into districts, each with commanders and lieutenants. Order was established and negotiations entered into for the mutual safeguard of traders with the Hanse towns.
The nobles who ventured to oppose the authority of Wallace and his colleague were punished in some cases by the confiscation of lands, which were bestowed upon Sir Alexander Scrymgeour and other loyal gentlemen, and these grants were recognized by Bruce when he became king. In these deeds of grant Wallace and Moray, although acting as governors of Scotland, state that they do so in the name of Baliol as king, although a helpless captive in England. For a short time Scotland enjoyed peace, save that Earl Percy responded to the raids made by the Scots across the Border, by carrying fire and sword through Annandale; and the English writers who complain of the conduct of the Scots, have no word of reprobation for the proclamation issued to the soldiers on crossing the Border, that they were free to plunder where they chose, nor as to the men and women slain, nor the villages and churches committed to the flames.
