"This year, the Earl of Northumberland made a league and covenant and friendship with Owyn Glyndwr and Edmund Mortimer, son of the late Edmund Earl of March, in certain articles of the form and tenor following:--In the first place, that these Lords, Owyn, the Earl, and Edmund, shall henceforth be mutually joined, confederate, united, and bound by the bond of a true league and true (p. 151) friendship, and sure and good union. Again, that every of these Lords shall will and pursue, and also procure, the honour and welfare one of another; and shall, in good faith, hinder any losses and distresses which shall come to his knowledge, by any one whatsoever intended to be inflicted on either of them. Every one, also, of them shall act and do with another all and every those things which ought to be done by good, true, and faithful friends to good, true, and faithful friends, laying aside all deceit and fraud. Also, if ever any of the said Lords shall know and learn of any loss or damage intended against another by any persons whatsoever, he shall signify it to the others as speedily as possible, and assist them in that particular, that each may take such measures as may seem good against such malicious purposes; and they shall be anxious to prevent such injuries in good faith; also, they shall assist each other to the utmost of their power in the time of necessity. Also, if by God's appointment it should appear to the said Lords in process of time that they are the same persons of whom the Prophet speaks, between whom the government of the Greater Britain ought to be divided and parted, then they and every of them shall labour to their utmost to bring this effectually to be accomplished. Each of them, also, shall be content with that portion of the kingdom aforesaid limited as below, without further exaction or superiority; yea, each of them in such portion assigned to him shall enjoy equal liberty. Also, between the same Lords it is unanimously covenanted and agreed that the said Owyn and his heirs shall have the whole of Cambria or Wales, by the borders, limits, and boundaries underwritten divided from Leogoed which is commonly called England; namely, from the Severn sea, as the river Severn leads from the sea, going down to the north gate of the city of Worcester; and from that gate straight to the ash-trees, commonly called in the Cambrian or Welsh language Ouuene Margion, which grow on the high way from Bridgenorth to Kynvar; thence by (p. 152) the high way direct, which is usually called the old or ancient way to the head or source of the river Trent; thence to the head or source of the river Meuse; thence as that river leads to the sea, going down within the borders, limits, and boundaries above written.
