She also began one that was aborted after she was captured and recaptured. On her ninth voyage a French privateer again captured her, but this time her captor plundered and then released her. She returned to merchant trade until she sank on 24 May 1810 in the Old Dock at Liverpool.
- Ann (1797 ship) was built in Batavia in 1797. She came into British hands and made a voyage for the British East India Company (EIC).

She then made one voyage for the British East India Company (EIC).
- Ann (1801 ship) was launched at Rotherhithe in the River Thames in 1801. She made eight voyages for the British East India Company (EIC) as an "extra ship", i.e., under charter, between 1801 and 1817. After 1817 she traded with India for some time and she was last listed in 1826.
