The young King, thinking the time ripe for the downfall of Mortimer, took counsel with Lord Montacute how he should proceed. A Parliament was going to be held at Nottingham, and that lord recommended that the favourite should be seized by night in Nottingham Castle, where he was sure to be. Now, this, like many other things, was more easily said than done; because, to guard against treachery, the great gates of the Castle were locked every night, and the great keys were carried up-stairs to the Queen, who laid them under her own pillow. But the Castle had a governor, and the governor being Lord Montacute’s friend, confided to him how he knew of a secret passage underground, hidden from observation by the weeds and brambles with which it was overgrown; and how, through that passage, the conspirators might enter in the dead of the night, and go straight to Mortimer’s room. Accordingly, upon a certain dark night, at midnight, they made their way through this dismal place: startling the rats, and frightening the owls and bats: and came safely to the bottom of the main tower of the Castle, where the King met them, and took them up a profoundly-dark staircase in a deep silence. They soon heard the voice of Mortimer in council with some friends; and bursting into the room with a sudden noise, took him prisoner. The Queen cried out from her bed-chamber, ‘Oh, my sweet son, my dear son, spare my gentle Mortimer!’ They carried him off, however; and, before the next Parliament, accused him of having made differences between the young King and his mother, and of having brought about the death of the Earl of Kent, and even of the late King; for, as you know by this time, when they wanted to get rid of a man in those old days, they were not very particular of what they accused him. Mortimer was found guilty of all this, and was sentenced to be hanged at Tyburn. The King shut his mother up in genteel confinement, where she passed the rest of her life; and now he became King in earnest. The first effort he made was to conquer Scotland. The English lords who had lands in Scotland, finding that their rights were not respected under the late peace, made war on their own account: choosing for their general, Edward, the son of John Baliol, who made such a vigorous fight, that in less than two months he won the whole Scottish Kingdom. He was joined, when thus triumphant, by the King and Parliament; and he and the King in person besieged the Scottish forces in Berwick. The whole Scottish army coming to the assistance of their countrymen, such a furious battle ensued, that thirty thousand men are said to have been killed in it. Baliol was then crowned King of Scotland, doing homage to the King of England; but little came of his successes after all, for the Scottish men rose against him, within no very long time, and David Bruce came back within ten years and took his kingdom.
