The Battle

History & Significance

Edward Bruce began the siege of Stirling Castle — the last major English fortress in Scotland. Unable to take it quickly, he made an agreement with the garrison commander Philip Mowbray: if the castle was not relieved by a large English army by Midsummer Day 1314, it would be surrendered. Robert Bruce was reportedly furious with his brother for giving England a year's notice and a specific deadline — which forced Edward II to respond with the largest army sent to Scotland since Edward I. The agreement directly caused the Battle of Bannockburn.
