When did Robert Bruce defeat Edward ii?

Robert Bruce did not directly defeat Edward II in a single battle, but he was instrumental in the broader conflict known as the Wars of Scottish Independence. Notably, Bruce's forces achieved a significant victory over the English at the Battle of Bannockburn in June 1314, which was a turning point in the struggle against English rule. Edward II was leading the English army during this battle but was ultimately forced to retreat, solidifying Bruce's position as a key figure in Scottish history.
