Military career.
In 1824, at the age of 15, he entered the Royal Navy College in Angoulême, where he was soon noticed for his wit, as evidenced by the many reports he was the subject of.
Student of 2nd class on September 20, 1826, 1st class on September 1, 1828 he embarked on the corvette "Victorieuse". During the four years that followed, he alternated no less than ten embarkations, with periods ashore in Toulon.
Promoted ensign on December 31, 1830, he embarked on the brig "Du Couëdic" with which he participated in the French conquest of Algeria and where he met ensign Gaston de Roquemaurel, future second in command of the "Astrolabe". In 1832, he embarked on the corvette "Isis".
On April 10, 1837, he was appointed "Lieutenant de vaisseau". The same year, he presented his candidacy for a place in the Dumont d'Urville second expedition. He had a major asset, he was the cousin of Commander Charles Jacquinot, who took him on board the corvette "Zélée" as second lieutenant. 
During this expedition, Thanaron was often in charge of hydrographic surveys. In this capacity, he was in charge of the plan of Voces Bay (Strait of Magellan). He accomplished his work with competence and was decorated with the Legion of Honor on the return of the expedition on January 25, 1841.

Then, from 1846 to 1848, he was second in command of the steam frigate "Infernal", then commander of the same ship on a temporary basis for four months. It was another rare fact for a lieutenant of a ship to be in command of the same ship for four months. In January 1850, he left for Africa and ordered, still provisionally, the steam-powered aviso "Chimère". Promoted to "Capitaine de frégate" on October 21, 1850, he received the titular command of another steamboat aviso the "Cerbère".
