Like his younger brother Charles, Edward Henry A’Court fought for many years in the Napoleonic wars, though in his case in the navy. In 1800, on his first ship, he served in the Channel and off the Western Isles. In November 1803, ‘in command of a boat with only five hands, he succeeded in capturing, after a severe struggle, a French schooner, with a detachment on board, besides other passengers, of between thirty and forty soldiers’. In January 1804 he was in joint command of part of the successful invasion force against Curaçao. Promoted lieutenant for these exploits, he saw service with several vessels on the Jamaica station and at the Cape. He was captain of the Owen Glendower in 1811 and of the Perseus, 1813-15, in the Mediterranean, and off Newfoundland and Halifax.
A’Court was probably also involved in the electoral management of Heytesbury, now fully under the control of the family, but seems to have mostly deferred to his brother Charles, with whom he was returned unopposed for the borough at the general election of 1820. In the Commons he was one of the almost silent members of the ‘ministerial phalanx’.
jumped on the table and said, if they wished to fight, he was ready, that he had come into the House of Commons a few weeks before and had been glad to do so because he thought it would introduce him into a society of gentlemen, but that it had never before been his fate to be in company with such a set of blackguards, and that the sooner he got out of Parliament the better he should be pleased.

He voted against more extensive tax reductions to relieve distress, 11, 21 Feb., and abolition of one of the joint-postmasterships, 13 Mar. 1822. He divided against inquiry into the right of voting in parliamentary elections, 20 Feb., abolition of the tax on houses worth less than £5, 10 Mar., repeal of the Foreign Enlistment Act, 16 Apr., and inquiry into the legal proceedings against the Dublin Orange rioters, 22 Apr. 1823. He voted against reform of the representation of Edinburgh, 26 Feb. 1824, 13 Apr. 1826, and inquiry into the prosecution of the Methodist missionary John Smith in Demerara, 11 June 1824. He divided for the Irish unlawful societies bill, 25 Feb. 1825, and against Catholic relief, 1 Mar., 21 Apr., 10 May, and the Irish franchise bill, 26 Apr. He voted for the duke of Cumberland’s grant, 30 May, 6, 10 June 1825.
A’Court was again returned unopposed for Heytesbury at the general election of 1826, as he was in 1830 and 1831. He voted against Catholic relief, 6 Mar. 1827, 12 May 1828. He may possibly have travelled to Russia during the latter year, on the appointment of his brother, now Lord Heytesbury, as ambassador. No trace of parliamentary activity has been found during the 1829 session, and Planta, the Wellington ministry’s patronage secretary, listed him among those who would be absent from the House when Catholic emancipation was considered. He probably remained opposed to this, however, as the wife of the Russian ambassador, Princess Lieven, told her brother Alexander Benckendorff that ‘your Captain A’Court’, whom she and her husband considered ‘a charming man’, ‘would not vote in the final division in the Commons’.
At the ensuing general election, A’Court apparently canvassed Wiltshire against the pro-reform and, in the end, unopposed sitting Members.
