This great battle which for the time overthrew the Bernician dynasty and gave the dominion of all Northumbria to Edwin of Deira was fought probably in the year 617. Edwin, who was born in 585, and whose life since he was a child of three years old had been passed in exile, was therefore a man thirty-two years of age when he thus recovered his father’s kingdom. The sons of Ethelfrid fled to the Celts of Scotland, and at least one of them sought the friendly shelter of Iona. Edwin no doubt fixed his capital at York, that great and important city which under its Anglian name of Eoforwac carried on the traditions of Roman Eburacum. The fact that the Roman name subsisted still with so little change in the language of the conquerors makes it probable that there was here no such utter destruction and desolation as at Anderida and Chester, but that there was a continuous civic life from the departure of the last Roman soldier to the enthronement of the first Anglian king. How gladly would we exchange much of the scanty knowledge of the invasion that we do possess for the details of the capture of the Roman capital of the north;[58] but over this conquest, as well as over that of the sister city of Londinium, there hangs a pall of impenetrable darkness. The lines of the Roman city may still be traced with considerable precision; the noble ruin of the multangular tower clearly marks its western corner, but we have not yet recovered, possibly shall never recover, the site of the once stately edifice where the Roman _Dux Britanniarum_ dwelt aforetime, and where in all probability the Anglian kings of Deira held their court. There, however, we may safely imagine Edwin enthroned; from thence his armies marched forth along one or other of the great network of Roman roads which centred at Eburacum. One of his earliest conquests was probably that of the British kingdom of Elmet or Loidis which still lingered on in the dales of the West Riding, but seems to have come to an end about this time. Having consolidated his power over Northumbria, Edwin became the mightiest of all the English kings. The title of Bretwalda was recognised as rightfully belonging to him, and all the other kings of Britain, Anglian, Saxon, Celtic, for a time at least acknowledged him as in a certain sense their superior. Even the islands of Man and Anglesey were added by him to his dominions, the latter island probably deriving from this conquest by the Angles the name which it still bears. Only Jutish Kent still maintained its independence, and with its king Edwin before long formed a close tie of alliance. An unexplained phenomenon in these first ten years of Edwin’s reign, during which, still heathen, he seems to have been pursuing a career of unbroken success, is the disappearance of East Anglia from the scene. It was the might of Redwald the East Anglian which broke the power of Ethelfrid on the great day of the battle at the river Idle, and yet we hear of
