[1] On 5 November as Parthian was bringing dispatches back to England she encountered a corvette and three brigs in the Bay of Biscay at 48°N 11°W / 48°N 11°W / 48; -11.

[1] A master's mate, angry at being disrated, shot Captain Balderston as Parthian was getting under weigh from Plymouth for Cadiz.

The British recognized the brig as the famous privateer Nouvelle Gironde, and gave chase.

[8] Commodore Owen placed Captain Dawson in charge of a division of gun boats covering the retreat of the rear guard during the evacuation in December.

[10] In January 1810 Lloyd's List reported that Parthian had recaptured Thames, Greeve, master and sent her into Fowey.

[12][13] Three of these may have been the three vessels laden with pitch, tar, rope, seed, and linseed that Parthian brought into Yarmouth on 11 May.

[1] Parthian, Pincher, and Thrasher were in company on 22 and 25 October when they captured To Wenner, Esperance, and Jeune Remmer.

[1] Ship arrival and departure data show Parthian subsequently sailing between Plymouth or Falmouth and Lisbon or Cadiz with mails or a messenger.

In the first half of 1824, two British vessels, Pilgrim and Shannon, sailed from Campeachy, Mexico for Bristol and Cork, respectively.

Neither arrived at their destination and were initially believed to have foundered in the Atlantic Ocean with the loss of all hands.

Shannon was burnt in the Laguna de Términos and the pirates stuck her captain's head on a post on shore.

The pirate vessel was a pilot schooner armed with one 8-pounder gun, with a crew of 36 men under the command of Juan el Valenciano, and owned by Sr. Molas of Yalafar[24][25] On 21 June Parthian arrived at Sacrificios from Falmouth.

On her the British found Pilgrim's letter bag, and a quantity of clothes, among them several shirts with Captain Watson's initials.

[c] A report dated Alvarado, Veracruz, 28 June, stated that Parthian had passed by Sacrificios and seen a number of vessels anchored there that had been taken by pirates.

A report dated Mexico, 30 June, stated that Parthian had captured a pirate schooner off Silsa.

It was believed that the pirate vessel was the one that had taken the French brig Ancienne and put her captain and supercargo ashore 40 leagues from Alvarado.

Her anchors failed and the sea pushed her on to the shore between Marabout (Marabut) Island and Arab's Tower.

The subsequent court martial blamed a strong southerly current that had carried Parthian further west than Captain Hotham and the sailing master had realized.

The court martial board admonished them to be more careful in the future when sailing close to shore.
