[3] In October Endymion joined the North Sea fleet with orders to pursue the scattered Dutch ships in the aftermath of the Battle of Camperdown.

Endymion reached Plymouth, but the merchantman Bhavani wrecked on the French coast near Boulogne on 12 November.

[9] On 14 February 1800 Endymion and HMS Amazon recaptured Trelawney,[10] which had been sailing from Liverpool to Leghorn when the French privateer Bougainville had captured her.

[12] Endymion was sailing in company with Champion and a convoy for the Mediterranean when they came upon a heavily laden Portuguese ship from Brazil, totally dismasted and abandoned.

During these first years of service, Endymion took a number of French and Spanish prizes, mainly merchants and privateers, but also some warships of up to 20 guns.

She was 40 days out of Martinque, bound for Brest, and had a crew of 65 men under the command of lieutenant de vaisseaux Caro.

Seven days later, Endymion captured the French corvette Bacchante, of eighteen 12-pounder guns and 200 men, in the Atlantic after a chase of eight hours.

Bacchante, under the command of lieutenant de vaisseau Kerimel was returning to Brest after a three-month voyage to Santo Domingo.

Kerimel's attempts to escape resulted in Bacchante losing eight men killed and nine wounded; her return fire caused no casualties on Endymion.

Captain Charles Paget described Bacchante as a "remarkably fine Ship, of large Dimensions, quite New, and sails very fast."

[14] In July 1803 Endymion encountered the East Indiaman Culland's Grove, which was returning to Britain after having sailed to Bengal and Benkulen.

Culland's Grove's captain and second officer protested vehemently that this would leave them short-handed, but Paget was acting within the law.

The Royal Navy was short of men and was in the habit of stopping homecoming merchant vessels and taking some of their best sailors.

In 1807 she took part in the Dardanelles Operation, where she was detached to Constantinople with the British ambassador for negotiations with the Ottoman Empire.

The mission was a failure and when the squadron sailed back through the Dardanelles, Turkish shore batteries attacked the British, with Endymion suffering three killed and nine wounded.

In August 1810, Endymion, in company with HMS Princess Charlotte, sailed to the then little-known remote islet of Rockall.

John Purdy's Memoir[16] was long accepted for dating the first landing on Rockall as being on this voyage, on 8 July 1810.

To quote Hall's own book, "As we had nothing better on our hands, it was resolved to make an exploring expedition to visit this little islet.

Two boats were accordingly manned for the purpose; ... the artists prepared their sketch books and the geologists their hammers, for a grand scientific field day.

The sea on this "fine autumnal morning" was unusually smooth, but a swell of many feet made landing difficult and required a great deal of confidence when leaping ashore.

At this point planning began for a long stay on the island, despite their lack of provisions or fresh water.

On 6 December 1813 as John and James, Crosby, master, was returning from Chili with 1000 barrels of oil, Pomone captured her and sent her into Bermuda.

[b] On 1 January 1814, Endymion captured the American merchant ship Felicity in the Atlantic Ocean, set her afire, and sank her.

[26] The objective was the American frigate Adams, of twenty-six 18-pounder guns, which had taken refuge some 27 miles up stream at Hampden, Maine.

[28] On 14 January 1815, USS President under the command of Commodore Stephen Decatur left New York for a mission in the Indian Ocean.

Endymion's foresails had been damaged in the engagement and she hove to for repairs to the rigging (being unable to take possession of her prize due to a lack of boats that would "swim").

On the other hand, Endymion - as the smaller and weaker ship (see below) - managed to slow down and damage the American frigate, pouring in three raking broadsides that caused heavy casualties and forcing her to strike.

In this it is recorded that when Pomone's boats boarded President, Decatur insisted that his sword be sent to the captain of "the black ship" (Endymion), as he had struck to her alone.

In reality there is no debate, since witness testimony from officers on President stated clearly that no casualties were caused, due mainly to poorly aimed broadsides and many American personnel being below decks.

[33] On 8 December 1846, she rescued eight crew of USS Somers, which was wrecked off Vera Cruz, Mexico whilst blockading that port.
