During the
War of the Fifth Coalition, Bertoletti served in the Italian division under the command of
Eugène de Beauharnais, the Viceroy of Italy. At the outbreak of war, he led a brigade in
Achille Fontanelli's Division. Later, Jean Rusca took command of the division, which missed the
Battle of Piave River. Bertoletti led his brigade in an action at
Klagenfurt on 8 June and at Papa,
Hungary on 12 June, as well as the major
Battle of Raab on 14 June. During the
Battle of Wagram, his brigade defended Klagenfurt on Eugene's line of communications. In June 1813, Bertoletti
defended Tarragona with 1,600 soldiers against British Lieutenant-General
John Murray's 16,000-man army. Realising he could not hope to hold the outer walls with his small Franco-Italian garrison, he pulled back into the inner defences and two
outworks. Ultimately, Murray abandoned the siege and 18 heavy cannon when he heard that two French relief columns were due to arrive. When Murray's troops withdrew, Bertoletti alertly called for help from the nearest French column, which soon marched into the fortress. At the news that French reinforcements were nearby, Murray gave up a second plan to capture Tarragona. After the
Napoleonic Wars, Bertoletti served the
Austrian crown as
Generalmajor (July 1814),
Feldmarschalleutnant (1830) and
Feldzeugmeister (1845). He died in
Vienna. The
Arc de Triomphe bears the inscription BERTOLETTI on the 37th column. ==Sources==
