and made "Máel Coluim, son of the king of the Cumbrians" a king (Malcolmum, regis Cumbrorum filium, ut rex jusserat, regem constituit). The identity of Máel Coluim and the reasons for Siward's help are controversial. The traditional historical interpretation was that "Máel Coluim" is Máel Coluim mac Donnchada, known sometimes today as Malcolm III or Malcolm Canmore, and that Siward was attempting to oust Macbeth in his favour. The traditional historical interpretation that "Máel Coluim" is Máel Coluim mac Donnchada derives from the Chronicle attributed to the 14th-century chronicler of Scotland, John of Fordun, as well as from earlier sources such as William of Malmesbury. The latter reported that Mac Bethad was killed in the battle by Siward, but it is known that Mac Bethad outlived Siward by two years. A. A. M. Duncan argued in 2002 that, using the Anglo-Saxon Chronicle entry as their source, later writers innocently misidentified Máel Coluim "son of the king of the Cumbrians" with the later Scottish king of the same name. Duncan's argument has been supported by several subsequent historians specialising in the era, such as Richard Oram, Dauvit Broun and Alex Woolf. It has also been suggested that Máel Coluim may have been a son of the Strathclyde British king Owain Foel, perhaps by a daughter of Máel Coluim II, King of Scotland. Duncan in fact believes that the Battle of the Seven Sleepers did not lead directly to a change of leadership in the Kingdom of Scotland. It has been suggested that the chief consequence of Siward's expedition was not the overthrow of Mac Bethad, but the transfer of British territory—perhaps previously lying under Scottish suzerainty—to Northumbrian overlordship. Alex Woolf has posited that, in such a context, Máel Coluim might have been a discontented Cumbrian prince who had been forced to "put himself under English protection". Evidence for Northumbrian control of Strathclyde in this period includes 11th-century Northumbrian masonry found at the site of Glasgow Cathedral as well as early 12th-century claims from the archbishopric of York that Archbishop Cynesige (1051–1060) had consecrated two Bishops of Glasgow. Death and legacy The 12th-century historian, Henry of Huntingdon, in his Historia Anglorum, relates that when Siward was attacked by dysentery, fearing to die "like a cow" and wishing rather to die like a soldier, he clothed himself in armour and took to hand an axe and shield. Ennobled in such a manner, Siward
