Thomas de Beauchamp, 11th Earl of Warwick, KG (c. 14 February 1313 – 13 November 1369), sometimes styled as Lord Warwick, was an English nobleman and military commander during the Hundred Years' War. His reputation as a military leader was so formidable that he was nicknamed 'the devil Warwick' by the French. In 1348 he became one of the founders and the third Knight of the Order of the Garter.
Thomas was undoubtedly a brave warrior in battle and proved to be a strong military leader. For example, the 14th century Anonimalle Chronicle states that when news arrived of his landing at Calais, the Duke of Burgundy, whose forces were camped nearby, made a hasty retreat under cover of darkness to avoid an encounter with 'the devil Warwick'.
He fought in Scotland as captain of the army against the Scots in 1337 at the age of 24. He also fought in the Hundred Years Wars with France, commanding the English victory at the Battle of Crecy in 1346.
