Battle of Halidon Hill
The Battle of Halidon Hill took place on 19 July 1333 when a Scottish army under Sir Archibald Douglas attacked an English army commanded by King Edward III of England () and was heavily defeated. The year before, Edward Balliol had seized the Scottish Crown from five-year-old David II (), surreptitiously supported by Edward III. This marked the start of the Second War of Scottish Independence. Balliol was shortly expelled from Scotland by a popular uprising, which Edward III used as a "casus belli", invading Scotland in 1333. The immediate target was the strategically important border town of Berwick-upon-Tweed, which the English besieged in March.
