The Battle of Rivoli (14–15 January 1797) was a key victory in the French campaign in Italy against Austria. Napoleon Bonaparte's 23,000 Frenchmen defeated an attack of 28,000 Austrians under Feldzeugmeister Jozsef Alvinczi, ending Austria's fourth and final attempt to relieve the Siege of Mantua. Rivoli further demonstrated Napoleon's brilliance as a military commander and led to French occupation of northern Italy.
