The hired armed lugger Valiant served the Royal Navy on a contract from 5 May 1794 to 10 November 1801. She was of 109 90⁄94 tons (bm), and was armed with eleven 3-pounder guns.
Lieutenant Thomas Baker commanded Valiant from 20 May 1794 until he moved to HMS Fairy in November as her acting-captain. At the time, Valiant served in the Channel as part of the forces under Rear-Admiral John MacBride.
On 8 June 1794 Valiant played a small part in a striking encounter between a frigate squadron under the Guernseyman Captain Sir James Saumarez, and a larger, stronger French squadron. On 6 June, Saumarez received an order from Admiral Macbride to take his frigate, the 36-gun Crescent, the 32-gun frigate Druid, the 24-gun post ship Eurydice, and six cutters and luggers (Valiant being one of them), to Guernsey and Jersey, and then to reconnoiter the French coast around Cancale and Saint Malo for signs of the French fleet.
The squadron sailed on 7 December and on 8 December they were some leagues northwest of Guernsey when Saumarez sighted six sails in the distance. He did not think they were French, but he sent Valiant to investigate. As Valiant approached, the vessels hoisted French colours and fired on her. The French squadron sailed between the cutters and luggers on the one side and the three British ships on the other, so the small vessels fled back to Plymouth. Saumarez led the French south towards the Hannoways, both sides firing at each other but at such a distance that the fire was pro forma. He sent Eurydice, his slowest ship, ahead, while Crescent and Druid turned towards the Guernsey coast. Saumarez then sent Druid after Eurydice. Both vessels made it around the south coast of Guernsey into Saint Peter Port. Saumarez sailed close to Guernsey's western shore and through some rocks. What made this possible was Saumarez's pilot, Jean Breton, a Guernseyman who knew the waters well. The French gave up the chase, not being willing to risk their vessels in rocky waters they did not know. Tacking back and forth, Crescent sailed around Guernsey's north side and then south to Saint Peter Port. By 14 June Valiant had rejoined Saumarez.
