The Second War of Scottish Independence broke out in 1332 when Edward Balliol (seal pictured) led an English-backed invasion of Scotland. Balliol was crowned king but within three months was forced out of Scotland. He appealed to the English king, Edward III, who invaded Scotland in 1333 and heavily defeated a large Scottish army at the Battle of Halidon Hill. As allies of Scotland via the Auld Alliance, the French covertly supported the loyalists of David II, the Scottish king. Increasing friction caused the French king to start the Hundred Years' War. Forced to focus on the French theatre, the English lost ground in Scotland. In 1346, while Edward campaigned in France, David invaded England believing most of its previous defenders were in France. He was surprised by a sizable English force, which crushed the Scots at the Battle of Neville's Cross and captured David.
