1827 at the request of the Regent, Infanta Isabel Maria of Braganza, he gave up his ambitions because of the resistance he encountered among the new Portuguese elite and returned to Britain. In the 1840s, Beresford expanded the Bedgebury Estate near Goudhurst, Kent. He built the hamlet of Kilndown to the north west of Bedgebury. Legacy Napier, in his History of the Peninsular War, severely criticized the tactics of Beresford at the Battle of Albuera, which gave origin to a heated correspondence between the Marshal and the historian. The published letters of Beresford which are mentioned below refer to this controversy. Wellington himself had no illusions over Beresford's ability as a General, but he appreciated his abilities as a military organizer, and recommended that Beresford should take command if he himself were disabled. He published: Strictures on Certain Passages of L. Col. Napier's History of Peninsular War; Further Strictures; Refutation of Col. Napier's Justification, London, 1831–1834, 3 Vol.; Letter to Charles Edward Long, Esq. on the Extracts Recently Published from the Ms. Journal and Private Correspondence of the Late Lieut-Gen. R. B. Long, London, John Murray, 1833; A Second Letter to Charles Edward Long, Esq. on the Ms. Journal and Private Correspondence of the Late Lieut. General R. B. Long (1834). Also of interest is the Colecção das Ordens do Dia (Collection of Orders of the Day) produced by Beresford's general headquarters nos Anos de 1809 a 1823 (for the years 1809 to 1823), Lisbon, 13 Vol. (at the Library of the English Institute of the University of Coimbra). As a reward for his services in the fight against the French he was raised to the peerage as Baron Beresford, of Albuera and Dungarvan in the County of Waterford, on 3 May 1814. On 28 March 1823 he was further honoured when he was made Viscount Beresford, of Beresford in the County of Stafford. Beside many national and foreign honours and decorations he received the Grand Cross of the Portuguese Order of the Tower and Sword. Some authors infer that he also had the title of 1st Duke of Elvas; but no document recording the granting this title is extant. Beresford County, New South Wales, Australia was named in his honour. He is the namesake of Beresford, New Brunswick. Parliament Beresford was Member of Parliament (MP) for County Waterford from a by-election on 28 June 1811 to 25 April 1814,
