In the month of December 1542, shortly after the rout of Solway, in which the English made prisoners the flower of the Scottish nobility, the same messenger brought to Henry VIII. the tidings that the grief and shame of this defeat had broken the heart of king James V., and that his queen had brought into the world a daughter, who had received the name of Mary, and was now queen of Scotland. Without stopping to deplore the melancholy fate of a nephew whom he had himself brought to destruction, Henry instantly formed the project of uniting the whole island under one crown, by the marriage of this infant sovereign with the prince his son. All the Scottish prisoners of rank then in London were immediately offered the liberty of returning to their own country on the condition, to which they acceded with apparent alacrity, of promoting this union with all their interest; and so confident was the English monarch in the success of his measures, that previously to their departure, several of them were carried to the palace of Enfield, where young Edward then resided, that they might tender homage to the future husband of their queen.

The regency of Scotland at this critical juncture was claimed by the earl of Arran, who was generally regarded as next heir to the crown, though his legitimacy had been disputed; and to this nobleman,—but whether for himself or his son seems doubtful,—Henry, as a further means of securing the important object which he had at heart, offered the hand of his daughter Elizabeth.
