sentences:  At the outbreak of the War of the Third Coalition the year after, and with the Coronation of Napoleon I and the advent of the First French Empire on 2 December 1804, Ganteaume was promoted to Vice-Admiral, made a Count of the Empire, and appointed to command the fleet in Brest.In 1805, after the death of Vice-Admiral Latouche-Tréville and the outbreak of the Trafalgar Campaign, Napoléon briefly considered entrusting Ganteaume with an expedition to land an 18 000-man army in Ireland, in a move similar to what had been attempted in 1796 with the ill-fated Expédition d'Irlande; eventually, Ganteaume was ordered to the Caribbean to land reinforcements there and return to Europe with the fleets under Rear-Admiral Missiessy and Vice-Admiral Villeneuve.Adverse weather prevented Ganteaume from leaving Brest, and he finally departed one month after Missiessy.
