Following his victory at the Battle of Talavera in the Peninsular War, Arthur Wellesley was offered a peerage. The question was what title should he take. His brother, Richard Wellesley, Earl of Mornington, looked around and discovered that a manor in the parish of Wellington was available. It was also reasonably close to the family name. Because Arthur was still in Spain in command of the army fighting the French, Richard oversaw the purchase. By this process Arthur therefore became Marquess of Wellington. According to the book "Wellington as Military Commander" by Michael Glover, Arthur Wellesley first signed himself 'Wellington' on 16 September 1809. At the Battle of Waterloo in 1815, Arthur Wellesley was already further elevated to the peerage rank of the Duke of Wellington. At the time he became Ambassador to France, "The London Gazette" of 4 June 1814 refers to him as having that title but suggests that it was granted by warrant on 25 August 1812.
