[1] In January 1136, during the first months of the reign of Stephen, David I crossed the border and reached Durham.
On 5 February 1136, Stephen reached Durham with an imposing troop of Flemish mercenaries, and the Scottish king was obliged to negotiate.
Stephen recovered Wark, Alnwick, Norham and Newcastle, and let David I retain Carlisle and a great part of Cumberland and Lancashire, alongside Doncaster.
David I asked his son Henry, to make the oath, in return for which he was made Earl of the Honour of Huntingdon and Northampton which up to that point had been held by his father.
In 1138, David invaded the North of England again, leading to the Battle of the Standard and the Treaty of Durham (1139).
