By tradition, during the Wars of Scottish Independence, chief Robert Munro, 6th Baron of Foulis led the clan in support of Robert the Bruce at the Battle of Bannockburn in 1314. Robert Munro survived the battle but his son, George, was killed. George however had already had a son of his own, also called George, who succeeded his grandfather Robert as chief and led the clan at the Battle of Halidon Hill in 1333 where he died.
