James Douglas, Lord of Douglas

Sir James Douglas, called the Black Douglas (c. 1286–1330), was Robert the Bruce's most feared lieutenant in the Scottish Wars of Independence. He retook Douglas Castle in the 1307 massacre remembered as the Douglas Larder, seized Roxburgh Castle in 1314 and fought at Bannockburn.

His raids into England helped force the 1328 Treaty of Northampton. After Bruce died he carried the king's heart to Spain and was killed fighting the Moors at Teba on 25 August 1330.
