Battle of Bannockburn

The Battle of Bannockburn was fought on 23–24 June 1314, between the army of Robert the Bruce, King of Scots, and the army of King Edward II of England, during the First War of Scottish Independence. It was a decisive victory for Robert Bruce and formed a major turning point in the war, which ended 14 years later with the de jure restoration of Scottish independence under the Treaty of Edinburgh–Northampton. For this reason, the Battle of Bannockburn is widely considered a landmark moment in Scottish history.

King Edward II invaded Scotland after Bruce demanded in 1313 that all supporters, still loyal to ousted Scottish king John Balliol, acknowledge Bruce as their king or lose their lands. Stirling Castle, a Scots royal fortress occupied by the English, was under siege by the Scottish army.
