In May 1482 James III's brother, Alexander, Duke of Albany landed in England at Southampton from France in a Scottish carvel, the Michael, captained by James Douglas.
According to the Fotheringhay treaty, Alexander, if he became King of Scotland, would reserve to Edward IV the town of Berwick upon Tweed, Lochmaben Castle with land in southern Scotland in Annandale, Liddesdale, Eskdale and Ewesdale.
