The French Navy requisitioned her in March 1794 for coastal escort and patrol purposes.

[3] On 16 March 1798 HMS Magnanime was escorting a small convoy when she spied a privateer lurking about, seeking an opportunity to pick off a prize.

Captain Michael de Courcy set Magnanime in chase.

She had been armed with 18 guns, eight of which she had thrown overboard during the chase, and had a crew of 107 men.

The Royal Navy took her into service under the name HMS Pandour, but never commissioned her.
