In 1803 Symes was obliged to give up a promising military and diplomatic career in the East Indies for the sake of his health. Lord Wellesley recommended him to the prime minister, 5 Nov., by reference to his two important missions to Burma and a third in ‘Hindo-stan’ which he had been obliged to forego, and to his ‘integrity, knowledge and discretion’, which would afford Addington ‘the most satisfactory information on every subject connected with the political interests of the British Empire in India’.
It was very likely at Wellesley’s instigation that Symes came in for Lord Charleville’s borough of Carlow on a vacancy in June 1806: but the seat was not available to him at the dissolution. Symes, with another Wellesleyite, Henry Montgomery, was unsuccessful in contesting St. Ives, where they were to have paid £3,500 each for their return and formed part of a squad of eight Wellesleyites in Parliament.
Although Symes was thought to have good prospects at St. Ives if ‘properly patronised and better supported’,
civil and military virtues and accomplishments were equally the objects of admiration. He possessed the highest capacity for science, with the most shining talents for action; and was not less endowed with the amiable qualities which embellish private life.
