Hot and stirring was the Douglas blood, and hardly a battlefield of the Middle Ages in Scotland but was stained with some of its best. Derived far back amid the mists of antiquity, none could tell how the race arose, and it was wont to be a boast with the house that none could point to its “first mean man.” There is a tower in Yarrow by the Douglas (_dhu glas_, black water) Burn which is said to have been the stronghold of “the Good Lord James”; and amid the fastnesses of Cairntable in Lanark there is another Douglas Water and Douglas Castle. From one of these, no doubt, in ancient Scots fashion, the family took its name; but when that happened, and what the story was of its early days, must remain a tale untold. The house’s mediæval greatness began, however, with the rise of Robert the Bruce, and from that time onwards its deeds mark with stain or blazon every page of Scottish history. Lords of the broad Scottish Border, east and west, their hands were sometimes stronger than the King’s. At one time a Douglas could ride to the field with twenty thousand spears at his back, and the gallop of the Douglas steeds sometimes was terrible alike on the causeway of Edinburgh and on the moorland marches of Northumberland. Douglas Earls and Knights fought as leaders through all the wars of David Bruce. A dead Douglas in 1388 won the famous fight with Hotspur on the moonlit field of Otterbourne. At Shrewsbury, in the days of Robert III., Henry IV. of England himself ran close to being hewn in pieces by the Earl of Douglas; and for gallantry on the battlefields of France this same great Earl was invested by the French King with the Dukedom of Touraine. The fame of Scottish chivalry for three hundred years was blown abroad under the Douglas name; for courtesies and blows alike were exchanged by the race on many battlefields besides those of the northern Borderland. Not that dark deeds are lacking in their history. Dark deeds belonged to their times. But in the tilting-yard or on the tented field were to be met no fairer foes. Nor was their heroism all of the sword-and-buckler order, or confined to one sex. The finest thing recorded of the race, after all, was done by a woman. On that dark February night in 1437, when James I. was murdered in the Blackfriars Abbey at Perth, when the noise and clashing was heard as of men in armour, and the torches of the coming assassins in the garden below cast up great flashes of light against the windows of the King’s chamber, was it not a Catherine Douglas who, for lack of a bolt, thrust her own fair arm into the staples of the door?
