French frigate Hortense (1803)

The Hortense was a 40-gun Hortense Class frigate of the French Navy.

In January 1805, under Captain Delamarre de Lamellerie, she was sent to observe British movements off Toulon, along with Incorruptible. On 4 February, they attacked a convoy, destroying 7 ships. Three days later, they encountered another convoy escorted by the 20-gun sloop HMS Arrow (1796) and the 8-gun bomb vessel HMS Acheron (1803); the French frigates destroyed the two Royal Navy vessels and captured three ships of the convoy.

Hortense took part in the Battle of Cape Finisterre, in the Battle of Trafalgar and in Lamellerie's expedition.

In 1814, she was renamed to Flore.
