The last time that Dunbar resounded to the march of an army bent on immediate fight was in 1745, when the boastful English general, Sir John Cope, landed here to engage the Highland followers of Prince Charles Edward (called the "Young Pretender"). Prince Charlie was at Edinburgh, and Dunbar Castle commanded the road into England. Cope asserted that the Highlanders would run away at the mere sight of his army. He marched westward, but was surprised in the early morning by his enemies when near Prestonpans. In less than ten minutes it was the unprepared English who were flying in disorder, utterly routed. The foregoing is but a brief outline of the stormy history of those grey and ruined battlements overlooking the bleak North Sea at the southernmost point of entrance to the noble Firth of Forth. The mention of these stirring incidents, however, will serve to show what a very important place Dunbar was, and that it was necessary to Scottish safety that a strong hand should have charge of its fortress. We are now to see how at one of the most critical hours a woman was to hold command, and to hold it worthily. Early in the reign of King Edward III. of England Scottish affairs were in some confusion. King Robert Bruce had lately died, leaving a son, King David II., then only five years old. That great leader and friend of Bruce, Randolph, Earl of Moray, was appointed Guardian of Scotland, but he too soon died. Edward III., anxious to interfere in Scottish affairs, agreed to help Edward Balliol to make himself king of the Scots. So an English army was again in Scotland, and one of the places they were keenest to take was the fortress of Dunbar. [Illustration: _Black Agnes_] The castle was a very strong one. It was built on a chain of great rocks that stretched out to sea, and could only be reached from land by one road, which was, of course, strictly guarded. The lord of the castle was the Earl of March (the word March in those days meant a border-land), but he was away with the Scottish army, and his wife was in charge of the castle. She was the daughter of that brave Earl of Moray, Guardian of Scotland, who has just been mentioned. The English army was led by an experienced general, the Earl of Salisbury, and he probably thought that he would not have much trouble in overcoming "Black Agnes," as the dark-haired countess was called.
