Entered military service as a volunteer with the Royal Corsican regiment, in garrison at Antibes, on 24 June 1770, and in the following month became second lieutenant in the Colonel's Company. He continued to serve with this unit as lieutenant (1774), then as second captain (1781). On 14 May 1788 he transferred with this rank to the Corsican Chasseurs, formed by splitting his former regiment into two. At the time of the formation of the battalions of volunteers, he was elected lieutenant-colonel of the 4th of Isère (18 November 1791). He served with the Army of the Alps, particularly at the affair of the Col de La Madeleine, and, having become chef de brigade of the 46th Line (27 February 1794) he was wounded at the action of Colle Ardente (26-7 April 1794). On 24 December 1795, the Directory confirmed his appointment to the rank of general of brigade, signed by Massena. In Italy, in 1796, he distinguished himself at Mondovì (22 April), at Castiglione (3 and 5 August) and in the actions around Mantua. On 14 November 1797 he became a general of division in the service of the Cisalpine Republic. At the time of the disasters in Italy after the formation of the Second Coalition, his superiors appointed him commander of the fortress of Turin (3 may 1799). The defensive works were in a poor state, and the garrison was insufficient in numbers and quality. It not being possible to defend the town effectively, General Fiorella took measures to reinforce the citadel. From 4 June 1799 the enemy opened his entrenchments and commenced a deadly and destructive bombardment. When all defence seemed impossible, a council of war of the fortress decided for surrender (20 June). The garrison was to made prisoner, but to keep it for the Republic, the general offered himself instead, with his staff, and was taken to Austria as a prisoner. In 1801, he was reintegrated as a general of brigade in the French service, and employed in Italy. On 30 April 1804, he became lieutenant-general in the service of the Italian Republic. During the whole period of the Empire, he exercised commands in Lombardy and Venetia, except for a short campaign in the Tyrol in 1809, at the time of the insurrection of the hotel-keeper Andreas Hofer. On 10 October 1809, he became a senator of the Kingdom of Italy. He had then remarried in the country, to Marie-Félicité Goetti (1805). He left the Po valley in 1814, and, during the Hundred Days, was for a some weeks the commander of the arrondissements of Ajaccio and Sartène. Under the Restoration, he had serious difficulties in having validated his appointment to the rank of lieutenant-general, which had been obtained in the Kingdom of Italy. He succeeded none the less (16 February 1817). The governor of Corsica, the Marquis de Rivière,
held him, however, to be somewhat suspect. In his report on the subject of retiring Fiorella, he did not fear to say "the general has the right to the maximum according to his age and the seniority of his service, but he has behaved badly, and will always behave badly towards the King, according to the reports I have had. He only deserves the minimum". A road in Ajaccio is named after him. Balteau, J. and others. Dictionnaire de biographie française, Paris, 1933-, vol. 13, pp. 1380-1.
