But being one of the Three Keys of the kingdom, its possession was eagerly sought during any foreign or civil war, great efforts being made both to attain and retain it. In 1296, Edward I. took Stirling for the second time, and held it for three years. Wallace had won a great victory within sight of the walls, a victory which had dispersed the English army, but had not been sufficient to take the castle. When the Scots obtained possession in the winter of 1299 after starving the garrison into surrendering, Sir William Oliphant became governor of the castle, to himself sustain a siege of many months in 1304. Edward I. was so angry at being hindered from his purpose for so long, that when he at last gained the castle he broke faith with Oliphant, sending him to the Tower of London. Ten years later, when Robert Bruce was winning back Scotland from the feeble grasp of Edward II., Stirling still held out. With superlative chivalry, Edward Bruce, who was conducting the siege, promised a year's respite, after which the castle must surrender unless relieved. Urged by dire necessity, Edward II. was persuaded to leave his frivolous Court, and gathering a magnificent army to march to Scotland. But all their splendid equipment did not avail against the courage and ingenuity of the Bruce, who, on the field of Bannockburn won for Scotland her greatest victory. Thousands of the English lay dead upon the field, while Edward fled for his life. Stirling Castle surrendered, and its fortifications were levelled. Once again Stirling was to be held by the English, when Bruce's son was on the throne; but in 1342 it was regained, never to fall again into the hands of a foreign foe. In a room in the castle, still pointed out by the guide, William, Earl of Douglas, was murdered by his royal master, James II. By special invitation, backed by a safe-conduct signed by the King, Douglas had come to Stirling in 1452. When supper was over, the King took Douglas into an inner room, where he accused him of being in league with Ross and Crawford against his monarch, and ordered him to break his bond. The haughty Douglas refused to do so, whereat James, forgetful of his safe-conduct, struck at him with his dagger, and the courtiers in attendance, dashing to the assistance of their King, Douglas fell covered with wounds, as the Duc de Guise was to do over a century later in the cabinet of Henri III. Douglas was undoubtedly a danger to his country, at the head of so powerful and unruly a house, but James should have taken more legal measures to subdue him. However, the Parliament of his day acquitted him of all blame. [Illustration: STIRLING CASTLE. One of the three Keys of Scotland, acting as a stronghold against the Highlanders of the North.]
