Osterley (1771 EIC ship)

Osterley was an East Indiaman launched on 9 October 1771 by Wells, Deptford. She made two voyages for the British East India Company (EIC) before the FRENCH FRIGATE Pourvoyeuse captured her on 21 February 1779 while she was on her third voyage. She then sailed for a few years as a French merchantman.

Career
1st EIC voyage (1771–1773): Captain Francis Fortescue sailed from the Downs on 18 May 1772, bound for Bencoolen and China. Osterley reached Bencoolen on 18 May 1772, and arrived at Whampoa Anchorage on 1 August. Homeward bound, she crossed the Second Bar on 1 December, reached the Cape of Good Hope (the Cape) on 23 February 1783, St Helena on 13 March, and Ascension Island on 23 March, and arrived back at the Downs on 26 May.

2nd EIC voyage (1774–1776): Captain Fortescue sailed from the Downs on 26 December 1774, bound for St Helena and Bencoolen. Osterley reached St Helena on 11 March 1775 and Simon's Bay on 19 May before arriving at Bencoolen on 5 August. She then visited two ports on Sumatra (Manna on 10 November, and Pring on 27 November, before returning to Bencoolen on 24 December. Homeward bound, she was at St Helena again on 12 May 1776, and arrived back at the Downs on 17 August.

3rd EIC voyage (1778-capture): Captain Samuel Rogers sailed from Plymouth on 9 February 1778, bound for Madras and Bengal. British records give the date of her capture as 22 February 1779, suggesting that she was homeward bound at the time of her capture.

Capture and fate
On 6 May 1779, FRENCH FRIGATE Pourvoyeuse, under Captain Saint-Orens captured Osterley off Cape Agulhas, helped by the armed merchantman Elisabeth. In early June, Osterley, Pourvoyeuse, and Elisabeth arrived at Île de France (Mauritius).

Funds from the sale of the cargo were embezzled, leading to a heated dispute. Tronjoli, commander of the French forces in the Indian Ocean, demanded that Saint-Orens explain himself. The day before he was to testify before the authorities, Saint-Orens was found dead, officially from an aneurism, although rumour said that he had been mortally wounded in a sword duel with a M. Villeneuve, formerly a Counselor at Pondichéry.

After Tronjoly was recalled to France and transferred command of the French forces to Thomas d'Estienne d'Orves, he embarked on Osterley to return to Brest. He arrived in late April 1781.

She was sold as a merchant ship at Isle de France in January 1783. She continued to sail in the Indian Ocean until at least 1784.
