Edward II's defeat at Bannockburn confirmed Robert the Bruce's victory in the wars of Scottish independence. Edward II had marched into Scotland to relief the siege of Stirling. They were met by Bruce on the approach to Stirling, and despite outnumbering the Scots 2 to 1, a combination of bad morale, bad leadership and a very poor position led to an overwhelming victory for the Bruce and a defeat for Edward II from which his reputation could not recover. The defeat at Bannockburn left the north of England exposed to Scottish raids and allowed Edward Bruce, Robert's brother, to invade and devastate large parts of Ireland.
