As captain of HMS Endymion, he was involved in the action on 14 January 1815 which ended in the capture of the American warship USS President.

On 2 April 1798, he joined the yacht Princess Augusta on the River Thames as a 3rd Class volunteer.

In May 1800, he transferred as a midshipman to the 74-gun third rate ship of the line Kent, which was under the command of his cousin, Captain William Johnstone Hope.

The Indivisible and Dix-Août succeeded in shooting away Swiftsure's yards and masts, forcing her to surrender.

He continued to serve on Leda in the Mediterranean and the Home station under Captains John (or James) Hardy and Robert Honyman (or Honeyman).

He then joined Captain George Burlton in the 50-gun fourth rate Adamant,[3] which had just spent a year undergoing refitting.

In January 1808 Glatton and the brig-sloop Delight had received information that the French had captured four Sicilian gunboats and taken them into Scylla, near Reggio, Calabria.

[6] On 31 January 1808, as Delight approached the port, a strong current pushed her towards the shore and she grounded.

[3] In October 1809, a squadron under Rear-Admiral George Martin, of Cuthbert Collingwood's fleet, chased an enemy convoy off the south of France.

They succeeded in driving two of the three escorting ships of the line, Robuste and Lion, ashore near Frontignan, where their crews burnt them after dismantling them and stripping them of all usable material.

[9] The transports that had been part of the convoy, including the armed storeship Lamproie, of 18 guns, two bombards (Victoire and Grondeur), and the xebec Normande, sailed into the Bay of Rosas where they hoped that the castle of Rosas, Fort Trinidad and several shore batteries would protect them.

In 1811 Captain Hope took command of HMS Salsette, a Perseverance-class fifth-rate frigate of a nominal 36 guns.

On 7 March 1814, Endymion, Belvidera and Rattler captured the American privateer Mars, which was armed with 15 guns and had a crew of 70 men.

On 11 October 1814 Endymion's boats attempted to capture the notorious American privateer Prince de Neufchatel, but were unsuccessful.

Captain Henry Hope thereupon sent 111 men in five boats to cut out the privateer, which was defended by 40 Americans.

[18][19] On 14 January 1815, USS President, under the command of Commodore Stephen Decatur, left New York for the Indian Ocean.

[21] Following the arrival of Endymion and the President in Bermuda, Captain Henry Hope was presented with a silver plate in honour of his success.

[22] On 15 January 1815 Hope was made a Companion of the Order of the Bath for his role in the capture of President.
