of King James IV of Scotland, sister of King Henry VIII and half-sister of the deceased King James V. After Lennox had seized the French money and artillery that was sent to Mary of Guise, she offered the hand of her daughter Queen Mary in marriage. When the Parliament of Scotland rejected the Greenwich treaty, Lennox changed sides, and supported King Henry VIII's military efforts to secure a marriage between Queen Mary and his son Prince Edward, in the war now known as the Rough Wooing. In the summer of 1544 Lennox plundered the Isle of Arran, and made himself master of the Isle of Bute and Rothesay Castle, with the support of eighteen ships and 800 men supplied by King Henry VIII.
