John Stewart, 3rd Earl of Buchan and Constable of France

[William Douglas]

I have included this article on the strength of his marriage - and because I like his portrait.

John Stewart, Earl of Buchan (c. 1381 – 17 August 1424) was a Scottish nobleman and soldier who fought alongside Scotland's French allies during the Hundred Years War. In 1419 he was sent to France by his father the Duke of Albany, Regent of Scotland, with an army of 6,000 men. Stewart led the combined Franco-Scottish army at the Battle of Baugé on 21 March 1421, where he comprehensively defeated the English forces, proving that the English could at last be beaten. However, two years later, Stewart was defeated and captured by Thomas Montacute, 4th Earl of Salisbury at the Battle of Cravant in 1423. After the battle he was exchanged, and after his release in 1424 he was appointed Constable of France making him the effective Commander-in-Chief of the French army. On 17 August 1424 Buchan was killed at the disastrous Battle of Verneuil, along with most of the Scottish troops in France.

Stewart married Elizabeth Douglas (dc.1451), daughter of Archibald Douglas, 4th Earl of Douglas, who also died at Verneuil. They had just one child, Margaret Stewart (before 1425–before 1461), who married George Seton, 3rd Lord Seton.
