On 22 December 1783 he married Louise Marie Victoire Henriette Fayd'herbe de Maudave at Port-Louis, Mauritius.

The young Morard de Galles next became an ensign on board the frigate Hermine, and there received a mission to burn one of the corsairs which had taken refuge under the protection of the coastal batteries.

Favoured by a cloudy night, he boarded the enemy vessel and attached a coat of sulphur to one of her sides - a terrible explosion half an hour later announced the success of this audacious enterprise.

Returning to France, he remained attached to the group directing the naval building works at Brest until 1776, when he took to sea again in Duchaffault's squadron.

Morard was first officer on Annibal, under Trémigon, when she left with a division under Captain Suffren bound for the Dutch Cape Colony and Isle de France (Mauritius).

[8] However, he had barely arrived at Isle de France when he was appointed to Argonaute and ordered to rejoin the squadron outside Gondelour.

Morard was promoted to vice admiral in 1793 and given command of a squadron of three ships of the line and 7 frigates, with his flag on the 110-gun Républicain.

This expedition was a failure: Séduisant was wrecked in the passe du Raz as she tried to sail out of Brest, and long before seeing Bantry Bay, the fleet was blocked by opposing winds and had to find refugee in Rochefort.
