Battle of Cassano ( 1799 ) The Battle of Cassano d ' Adda was fought on 27 April 1799 near Cassano d ' Adda , about 28 km ENE of Milan . It resulted in a victory for the Austrians and Russians under Alexander Suvorov over Jean Moreau ' s French army . The action took place during the War of the Second Coalition during the larger conflict known as the French Revolutionary Wars . Background . While General Napoleon Bonaparte campaigned in Egypt , the Second Coalition launched an invasion of French - occupied Italy . General of Division ( MG ) Barthélemy Schérer fought inconclusive actions the Austrians at Pastrengo , Verona , and Legnago on 26 March 1799 . Feldmarschal - Leutnant ( FML ) Pál Kray and his Austrians then defeated Schérer at the Battle of Magnano on 4 April . This defeat forced the French army into a long retreat . Attempts by Schérer to hold the lines of the Mincio and Oglio rivers failed when an Austrian force led by FML Josef Vukassovich turned his northern flank . Schérer , completely out of his depth , handed over army command to the more capable MG Moreau . Austria ' s Russian allies , led by Suvorov , soon began appearing at the front . When Field Marshal Suvorov joined the allied army , he took over the top command from Kray , though the latter had just been promoted to Feldzeugmeister . The arrival of General of Cavalry Michael von Melas displaced Kray the top Austrian field command . Therefore , Kray was assigned to capture the fortress of Mantua , while Melas and Suvorov pursued the French . The Siege of Mantua lasted from April until the garrison surrendered on 28 July . Battle . Moreau deployed the divisions of MGs Paul Grenier , Claude Victor , Jean Sérurier , and Pierre de Laboissière to defend the line of the Adda River . The Austrians still made up the bulk of the allied army , since only three formations of Cossacks were present . The Austrian division commanders were FML Peter Ott , FML Johann Zoph , General - Major Franz de Lusignan ( acting commander for FML Michael Fröhlich ) , and FML Konrad Valentin von Kaim . Even before the battle , a Russian force under Petr Bagration outflanked the French position by seizing a bridge over the Adda at Lecco on 26 April . This put Sérurier ' s division in an awkward position . On 27 April , General of Cavalry Michael von Melas with the divisions of Fröhlich and Kaim stormed the French positions at Cassano , while Ott and Zoph attacked 6 km farther north at Vaprio d ' Adda . Suvarov ' s assault forced Moreau to retreat . Results . The French suffered 2 , 500 killed and wounded , plus 5 , 000 soldiers , 27 cannon , and 3 colors captured . The Austro - Russians lost 2 , 000 killed and wounded . Moreau retreated , leaving a 2 , 400 - man garrison in Milan ' s citadel . On 28 April , Vukassovich trapped Serurier ' s division at Verderio and the French lost another 300 killed and wounded , plus 2 , 700 captured . Grenier ' s division withdrew to Novara while Victor and Laboissière pulled back to Valenza . Another authority gives allied losses as 6 , 000 and French prisoners as 7 , 000 , without listing French killed and wounded . Kaim pressed on to capture Turin on 20 June . Milan ' s citadel capitulated on 24 May . The next major action was the Battle of Trebbia ( 1799 ) on 17 – 20 June .
