Neerwinden and
Wattignies. The following year he was involved in the sieges of
Landrecies and
Charleroi. In 1795 he fought in the Army of the Upper

Castiglione campaign, he commanded a brigade in the column of
Johann Mészáros. In the third relief attempt of the
Siege of Mantua, Hohenzollern commanded the army's advance guard. He led his troops in a hard-fought victory over
Napoleon Bonaparte during the
Second Battle of Bassano on 6 November. At the
Battle of Caldiero on 12 November, Bonaparte attacked Hohenzollern's advance guard with two French divisions. Though initially outnumbered two-to-one, he managed to repulse repeated enemy attacks until Austrian reinforcements arrived and drove the French back into
Verona. He played a lesser role in the
Battle of Arcole, after which the Austrians were forced to retreat. In April 1797, the Knight's Cross of the
Military Order of Maria Theresa was awarded to him.

Novi. He won promotion to
Feldmarschal-Leutnant in October 1799. Hohenzollern defeated
Nicolas Soult at La Bochetta near
Genoa on 9 April 1800 and at
Sassello on 10 April. He participated in the
Siege of Genoa under the overall command of
Peter Ott. On 13 May, Hohenzollern defeated and captured Soult at Monte Creto, ending a series of successful French sorties. After the fall of Genoa in early June, Ott appointed him commander of the captured port. After Bonaparte's decisive victory at the
Battle of Marengo on 14 June, Genoa passed into French hands again. Hohenzollern fought at the
Battle of Pozzolo in December 1800. In 1802, he became the proprietor of
