She served briefly as a tender to the frigate before mutineers and British prisoners recaptured her and sailed to Australia.

Seringapatam appeared in Lloyd's Register in 1800 as "East Indian" with W. Day, master, P. Mellish, owner, and trade London–Southern Fisheries.

She was one of the vessels in the convoy at the action of 4 August 1800, when HMS Belliqueux and the East Indiaman Exeter captured the French frigates Concorde and Médée.

[6] War with France had resumed in 1803 and Captain John Bird acquired a letter of marque on 7 August 1804.

[6] On 13 November 1807, Lloyd's List reported that she had captured two Spanish privateers round Cape Horn.

At the time of her capture Seringapatam did not have a letter of marque in hand as she had left before the outbreak of war with the United States and as she did not expect to encounter any French vessels.

Although she did not have a letter of marque in hand, she nevertheless, on her way, captured Edward, of Nantucket, which was carrying 1200 barrels of oil, and sent her in to London as a prize.

[14] In early 1813 Captain David Porter entered the Pacific, via Cape Horn, in the thirty-two gun frigate USS Essex.

Around the Galapagos, Porter and his men captured numerous British vessels and recaptured an American ship from the Peruvians.

One of the vessels he captured was the letter of marque Greenwich, of 338 tons burthen, armed with 10 guns and having a crew of 25 men under the command of Captain Shuttleworth.

[15] At Tumbes he fitted her up as a storeship, increased her armament to 20 guns, and put her under the command of Lieutenant John M. Gamble, USMC.

[16] Greenwich captured Seringapatam off Tumbes, Peru, on 13 July 1813, after an exchange of broadsides, but apparently no casualties on either side.

Seringapatam was somewhat damaged so Porter sent over his gunners and carpenters to work on her and in a few days they had repaired her, and upgraded her armament to 22 guns.

[16] Captain Stavers, when asked to surrender his privateer's commission, revealed that though he had applied for a letter of marque, he had not yet received one, but that it was probably waiting for him in Lima.

Captain Porter announced that Stavers would be taken to the United States and be tried as a pirate, and ordered him and his crew to be put in irons.

They were given more freedom after some liberated American whalers told Porter that the British had treated them well during their time as prisoners aboard Seringapatam.

[17] In September, Porter found the frigate Essex in need of repairs and provisions and set sail for the island of Nuka Hiva, in the Marquesas, nearly 3,000 miles away.

Soon after Porter sailed away, the local inhabitants became so troublesome that Gamble was forced to land a detachment of men to restore order.

In April 1814, despairing of Porter's return, Gamble began to rig Seringapatam and Sir Andrew Hammond with the intention of quitting the island.

[b] Despite this precaution, the mutineers freed the prisoners of war and together captured Seringapatam on 7 May, wounding Gamble in the process.

[18] On 16 October, at Governor Lachlan Macquarie's request, Captain Eber Bunker sailed Seringapatam to England, where she was returned to her owners.

Lloyd's List reported that 14 seamen from Greenwich and Sir Andrew Hammond had recaptured her in the Marquesas Islands and taken her into Port Jackson.

Captain Kenny of Asp received a report that the Spanish authorities were seeking Seringapatam's master for the death of two boys.

Seringapatam was at Tonga, and in March 1821 at Bay of Islands with 80 barrels of whale oil and "Toy", master.

The Hobart Town Gazette of 22 June 1822, reported that Seringapatam was in Derwent, having been "uncommonly successful since her short stay here", having taken five or six whales.

In 1852 Seringapatam returned to Lloyd's Register, still with Crichton, owner, but no master, and no trade, though she was listed as being at London.
