Early on the morning of the 11th of September the English began their passage across the narrow wooden bridge which was the only means of communication with the opposite bank of the river. It is evident that a large force would occupy many hours in crossing the river by this means, and during that time they must lie in a great measure at the mercy of a determined enemy. Wallace did not neglect the opportunity thus afforded him. He suffered the English to transport about one-half of their forces, and then took possession of one end of the bridge, thus effectually cutting off their further advance. He then surrounded the body of the enemy who were thus separated, threw them into confusion, and gained a bloody victory. Many thousands of the English fell by the sword or perished in the water, and among the dead was the treasurer, Cressingham. This man, during his administration had made himself peculiarly obnoxious to the Scottish people, and they now revenged themselves after a barbarous fashion, by stripping the skin from the dead body of their enemy, and cutting it into small pieces to be worn as the North American Indian of a later day carried the scalp of his fallen foe.

The Earl of Surrey had not crossed the river, and as soon as he perceived that the destruction of his troops was inevitable, he caused as many of them as could be collected to occupy the castle of Stirling, and then took horse and rode at full speed to Berwick. Among the Scots the loss was comparatively small, and the only man of note who fell was the patriotic Sir Andrew Moray of Bothwell. The result of this victory was no less than the restoration of the country to freedom. Wallace pushed his success without delay, and wherever he went his progress was almost without opposition. The castles of Edinburgh, Berwick, Dundee, and Roxburgh at once surrendered, and within a short time the rest of the Scottish strongholds submitted to the victor, so that there was not a fortress in the country remaining in the possession of the English king.

A few months later a famine arose in Scotland and, driven in some measure by the want of supplies, Wallace invaded England. He remained for awhile in Cumberland, and on his return an assembly of the nobility was held at the Forest Kirk, in Selkirkshire. It is generally understood to have been at this time that Wallace was invested with the title of guardian or governor of the kingdom of Scotland and commander of its army.

It is worthy of remark that the name of Balliol was retained in this instrument, and the appointment of Wallace was declared to be made with the authority of King John, whose legitimate right to the crown appears to have been universally recognised.

At this time Edward was still in Flanders, engaged in a war with Philip of France, which had followed the seizure of Guienne. A treaty of peace having been at length agreed to, Philip endeavoured to influence Edward in favour of the Scots, and to include them also in the amnesty. But the English king would listen to no such proposals. His conquest had been suddenly wrested from him, and he was intent on vengeance. He issued letters to the barons of the kingdom, commanding that the whole military force of the realm should be assembled at York on the 14th of January, 1298.

The immense army thus collected together, and numbering 100,000 foot and 4,000 horse, was placed under the Earl of Surrey, who led it as far as Berwick. On his arrival there, the earl received the king's direction not to proceed until he himself should be there to take the command.

Edward landed in England in March, and again summoned the barons, with all the forces at their command, to meet him at York at the approaching feast of Pentecost. A still more numerous army than before was thus organised, and the king placed himself at its head, and marched triumphantly towards the north. Having reached Roxburgh, he proceeded thence along the coast, attended by a fleet which had been dispatched to furnish the army with supplies. During this part of his course he encountered no opposition, saw no enemy, and the few habitations which were to be found along the route had been deserted by their inhabitants.

The Scottish patriots were gathered together among the mountains, and the great and noble of the land once more ranged themselves beneath the standard of Wallace. Among them was Robert Bruce, who now finally declared himself on the side of freedom. With a cool judgment, which merited a more fortunate issue, Wallace for a time avoided coming into collision with the enemy, whose overwhelming numbers threatened to crush him in an open conflict. He hung upon the flank of the English army unseen, but close at hand, ready to take advantage of any opportunity of inflicting damage upon it. The march of Edward was not unattended with difficulties. The scanty resources of the country were wholly insufficient to afford sustenance for his troops, and the store-ships were detained and driven about by contrary winds. A quarrel also took place between the English and Welsh soldiers under his command; and the latter, to the number of 40,000, showed a disposition to desert, and go over to the Scots. "Let my enemies," said Edward, "go and join my enemies. One day I will chastise them all." Meanwhile, the ships still failed to arrive, and the scarcity of provisions seemed likely to approach a famine. Edward was about to retreat to Edinburgh, when he learned that the Scottish army was encamped not far off in the wood of Falkirk. The news is said to have been brought to the king privately by two of the Scottish nobles, the Earls of Dunbar and Angus. He immediately determined to go forth to meet the insurgents, and on that night the royal army lay in the fields. Edward himself, sleeping beside his horse, received a kick from the animal, which broke two of his ribs. The news soon spread through the camp that the king had been killed, and a state of confusion ensued which threatened the complete demoralisation of the troops. Edward, however, restored discipline among them by mounting his horse, and riding at their head, regardless of the pain he endured.

The English army began its march at dawn on the 22nd of July, 1298. Within a short time the enemy were observed to have taken up a position in a field which lay at the side of some rising ground in the neighbourhood of Falkirk. The force under the command of Wallace was greatly inferior to that opposed to him; but he had posted his troops with great judgment, and for a long time the Scottish infantry repelled the furious attacks directed against them. Not so the cavalry, of whom Wallace possessed no more than 1,000. These did not even attempt to resist the superior numbers of the enemy, but, without striking a blow, they turned and fled from the field. Cowardice is certainly not the characteristic of the race to which these men belonged, and therefore their flight can only be attributed to treason on the part of their leaders. Be the cause what it might, the loss of this division speedily decided the fate of the day, and the heroic resistance of the infantry was rendered totally unavailing. The Scots at length gave way before the repeated charges of heavy cavalry, and the victory of the king was complete. Little or no quarter seems to have been asked or given, for we are told that 15,000 Scots were left dead upon the field.
