Archibald Douglas
Sir Archibald Douglas (before 1298–1333) was the younger son of William le Hardi and half-brother of the Good Sir James. When Edward Balliol invaded with English backing in 1332, Douglas surprised him in a night attack at Annan and drove him back to England.
He was appointed Guardian of Scotland in March 1333. In July he marched to relieve besieged Berwick and was killed leading the uphill assault at the Battle of Halidon Hill on 19 July 1333.
