The Battle of Sark, alternatively called the Battle of Lochmaben Stone, was fought between England and Scotland in October 1448. A large battle, it was the first significant Scottish victory over the English in over half a century, following the Battle of Otterburn of 1388. It placed the Scots in a position of strength against the English for over a decade, until Edward IV ascended the English throne, and it brought Clan Douglas to greater prominence in Scotland.
