Though our own documents fail to supply us with any further information as to the proceedings of Henry of Monmouth through the year 1407, and though he might have been allowed some breathing time by the decreased energy of the Welsh rebels, yet Monstrelet informs us that he was actively engaged in a campaign at the other extremity of the kingdom. The historian thus introduces his readers to this affair: "How the Prince of Wales, eldest son of the King of England, accompanied (p. 233) by his two uncles and a very great body of chivalry, went into Scotland to make war." He then commences his chapter by the not very usual assurance that he is about to relate a matter of fact. "Then it is the truth that at this time, 1407, about the Feast of All Saints (1st November), Henry Prince of Wales[225] mustered an army of one thousand men-at-arms and six thousand archers; among whom were his two uncles, the Duke of York, the Earl of Dorset, the Lords Morteines, de Beaumont, de Rol, and Cornwal, together with many other noblemen; who all marched towards Scotland, chiefly because the Scots had lately broken the truce between the two kingdoms, and done great damage by fire and sword in the duchy of Lancaster, and the district around Roxburgh. The Scots were not aware of their approach till they were near at hand, and had committed great devastation. As soon as the King of Scotland, who was at the town of Saint "Iango" (Andrew's) in the middle of his kingdom, heard of it, he issued orders immediately to his chiefs; and in a few days a powerful army was assembled, which he sent under the command of the Earl of Douglas and Buchan towards the Marches. But, when they were within six leagues, they learnt that the English (p. 234) were too strong for them. They consequently sent ambassadors to the Prince of Wales and his council, who brought about a renewal of the truce for a year; and thus the aforesaid Prince of Wales, having done much damage in Scotland, returned into England, and the Scots dismissed their army." [Footnote 225: The Pell Rolls record payment (16th November 1407) to the Prince, by the hand of John Strange, his treasurer of war, for one hundred and twenty men-at-arms and three hundred and sixty archers, then remaining at the abbey of Stratfleure, to reduce the rebels, and give battle in North and South Wales.]
