In 1327, when Edward III. was only fifteen years old, Douglas led a raid into Northumberland and Durham which did the English much damage. Edward came after them with an English army, and the Scots, being outnumbered, were compelled to dodge up and down in order to avoid a pitched battle. But in one bold night attack, Douglas and five hundred of the Scots penetrated to the king’s tent, and almost succeeded in taking him prisoner. Failing in this, they returned unharmed to their own country, and shortly afterwards, at the Treaty of Northampton in 1328, King Edward III. agreed to acknowledge Robert Bruce as King of Scotland, and the long war between Scotland and England ended. A year later Bruce died, but after a romantic custom of that day he bequeathed his heart to his gallant friend, Sir James Douglas. Douglas had this heart enclosed in a silver casket and carried it hung about his neck. The war with England being over, this restless knight sought adventures in Spain, fighting against the Saracen followers of Mahomet. In one fierce battle, he and his men were surrounded by their enemies. Douglas, probably realising that this was his last fight, took the casket and flung it into the midst of his foes, crying: "Go first in fight, as thou wert used to do; Douglas will follow thee or die!" He then rushed desperately after it, fighting his way on till at last his dead body fell on this dearly prized relic, which he guarded to the end. The casket lies buried in the Abbey of Melrose, but Douglas’s body was laid in his own church. Of the bold Earl Douglas who fought and died at Otterbourne the tale is told in our last chapter. We may pass on to another famous Douglas, this time a heroine, who lived in the reign of James I. of Scotland (quite a different king from James I. of England). When James was only twelve years old, he was taken prisoner by Henry IV. of England, and kept captive till he was thirty. But he was given an education fit for a king, and in England he met the lady he devotedly loved, Lady Joan Beaufort, daughter of the Earl of Somerset. He addressed a beautiful poem to her and married her, and these two always most dearly loved one another. When at last his long captivity came to an end, he got back to Scotland to find the kingdom in disorder, and the nobles defying the law and acting as they pleased. James, a strong and able king, set his strength against their strength, and gradually got his whole kingdom into order and ruled with wisdom and justice.
