Jean Dornal de Guy

Jean Dornal de Guy (13 October 1771 in Urrugne – 10 May 1855 in Saint Jean de Luz ) was a French naval officer.

Career
In 1803, Commander Dornal de Guy was serving in the flotilla at the Camp de Boulogne. On 7 August, a British brig and a cutter anchored off Boulogne; and the next day, Dornal de Guy received the order from Bruix to attack the ships with five boats. Due to the tides, he couldn't set sail until 3:00 a.m. the next day. The British put to sail and exchanged gun fire with the boats, before retreating.

In 1805, de Guy captained the frigate Félicité, in the Brest squadron. In 1806, he ferried troops, weapons and ammunitions from Brest to San Domingo, where he arrived in time to take part in the Battle of San Domingo. Félicité was among the three French ships that survived the battle, and she returned to Lorient on 26 March 1806.

In 1807, Dornal de Guy was appointed captain of the Manche at Cherbourg. Along with the brig Cygne under Menouvrier Defresne, Manche had several encounters with HMS Uranie, under Captain Christopher Laroche. On 20 June, Uranie made a lukewarm attack on the brig, to which the French hardly reacted. The incident later led to the court-martial and eventual dismissal of Laroche.

Manche captured the 16 gun brig-sloop HMS Seaflower (1782) on 27 September 1808 near Bengkulu.

In 1809, Manche was dispatched from Cherbourg to Port-Louis at Ile de France to replace the aging Sémillante, which had been decommissioned and sold to Robert Surcouf. De Guy arrived on 6 March, and after a one-month leave, Manche undertook her first cruise in the Mozambique Channel. Along with Vénus, she took part in the Action of 18 November 1809, capturing three large Indiamen. Dornal de Guy eventually returned to Ile de France after an eight-month patrol, along with Créole and two of the prizes.

After the capture of Jacques Hamelin at the Action of 18 September 1810, Dornal de Guy became the senior naval officer of the French forces in the Indian Ocean. In November, seeing that the British forces received sustained reinforcements, he moored his ships (Manche, Astrée, Bellone and Minerve) and disambarked the crews to reinforce the garrison of Port Louis. The Invasion of Île de France occurred in November, and the island surrendered the next month.
