In late August 1513 the Master of Angus rode out with his father the Earl, and his younger brother Sir William Douglas of Glenbervie at the head of a large Douglas contingent and their adherents. On reaching the mustering point at the Ellemford, north of Duns, they joined with the largest and most modern army that Scotland had ever fielded. The army proceeded under King James into England where it eventually met with the army of the Earl of Surrey at Flodden Edge.
