England has been destined in three wars to experience the truth that a country whose people refuse to submit to invaders cannot practically be conquered, however superior may be the invaders in military skill or resources: in a fourth war she helped the Spaniards to exemplify the same maxim. Between England and Scotland at the beginning of the fourteenth century no comparison was possible; the southern people were wealthier, more numerous, better organised. Yet the war begun by Wallace's brief career ended in the establishment of Scottish independence. So also the French had no chance in the field against the English of Edward III. and Henry V.; yet the English attempt at conquering France ended in total failure. The little English armies won nearly every engagement against the revolted American colonists; yet the task of subjugating the colonies would have been hopeless, even if other enemies had not assailed England, and hastened the catastrophe. Edward I. won a great victory at Falkirk, but he never was able to subdue Scotland. Just before his death the Scots found a new leader in Robert Bruce, representing the house rival to the Balliols at the time of the disputed succession and now accepted instead of them, who was duly crowned king. Edward's death stopped a great invasion of Scotland, and his incompetent son neglected Scottish affairs, till gradually the whole country was lost except Stirling Castle. This was, as has been pointed out, the most important post in Scotland: but it could not be held indefinitely, and the governor ultimately agreed to surrender unless relieved before Midsummer day 1314. Edward II. was driven for once into activity, and approached just in time, with an army to which the chroniclers ascribe the incredible number of 100,000 men. Robert Bruce had no choice but to await attack at Stirling: if he marched to meet his enemy, it was obvious that the English might evade him and reach Stirling unopposed. They might even, with their great superiority of numbers,[17] engage him on more than equal terms, and have plenty to spare to be pushed forward to Stirling. Fortunately for him, he had an admirable position ready to his hand within a very short distance.
