other leading figures and he missed the climactic battle where British forces successfully managed to evacuate in the face of Marshal Soult's army at which Moore was killed in action. Wellesley's Spanish campaign When British troops returned to the Iberian Peninsula after the Corunna Campaign, they were commanded by Sir Arthur Wellesley (later the Duke of Wellington). Charles Stewart was appointed, in April 1809, Adjutant General to Wellesley. This was an administrative job and not much to his liking, especially as Wellesley never discussed his decisions with subordinates. Nevertheless, he sometimes managed to see action and distinguished himself, particularly at the battle of Talavera (July 1809) for which he received the thanks of the Parliament on 2 February 1810 when he returned to England on sick leave. He also excelled at Bussaco in September 1810 and at Fuentes de Oñoro (May 1811) where he took a French Colonel prisoner in single combat.

Vienna In 1814 he was also appointed Ambassador to Austria, a post he held for nine years (1814–1823). On 18 June 1814, to make him more acceptable in Vienna, Stewart was ennobled as Baron Stewart, of Stewart's Court and Ballylawn in County Donegal, by the Prince Regent. In the same year, he received honorary degrees from Oxford and Cambridge, was admitted to the Privy Council, and was appointed a Lord of the Bedchamber to the King. Lord Stewart, as he now was, attended the Congress of Vienna with his half-brother Lord Castlereagh as one of the British plenipotentiaries. He was
