Crawford and John of Islay, stabbed him to death with his own hands, even though Douglas had been issued a safe conduct. Douglas's brothers, James Douglas, 9th Earl of Douglas, Archibald Douglas, Earl of Moray, Hugh Douglas, Earl of Ormonde, and John Douglas, Lord of Balvenie went into open rebellion against the Crown, but were finally put down in a skirmish in 1455 known as the Battle of Arkinholm; the royal forces were led by another Douglas, the "Red" George Douglas, 4th Earl of Angus. The Douglas brothers were all slain, either in battle or executed afterwards, except the 9th Earl who was in England at the time. The 9th Earl was forfeited, but continued to foment unrest in Scotland from England, until his capture at the Battle of Lochmaben Fair in 1484. The aged Douglas was forced to spend the rest of his days at Lindores Abbey, his estates being divided up between the King's supporters, most notably Angus. Black and Red Douglases Following the death of the 2nd Earl at the Battle of Otterburn in 1388 without legitimate issue, the Earldom passed to a bastard son of "The Good Sir James", the poetically named Archibald the Grim, the Lord of Galloway. This occurred through articles of special entail in the resignation of title by Hugh the Dull, Lord of Douglas. George Douglas, 1st Earl of Angus the bastard son of the 1st Earl by his sister-in law Margaret Stewart, Dowager Countess of Mar & Countess of Angus, inherited his mother's Earldom of Angus. Retrospectively the two branches of Douglas and Angus were described as the Black and Red lines respectively. The Black Douglases fell from power and were attainted by King James II in 1455. The seventh Earl was created Earl of Avondale and Lord Balveny in 1437, also in the Peerage of Scotland. These titles also became forfeit in 1455. The title of Douglas was restored in 1633 for the "Red" Douglas line, when William Douglas, 11th Earl of Angus (1589–1660), was created First Marquess of Douglas by Charles I.
