After a siege lasting from 2 to 26 May , General Eugenio Navarro ' s Spanish garrison capitulated . Spanish losses were 160 killed and wounded , 22 colors , 91 artillery pieces , and 7 , 000 prisoners who were paroled after agreeing not to fight against France until exchanged .

French losses were 150 killed and wounded . The French won a significant victory in the Battle of the Black Mountain on 17 – 20 December 1794 .

On the 13th around 2 : 00 PM , André Masséna probed the Austrian and Piedmontese positions which were fortified and supported by 18 pieces of artillery . The next day at 11 : 00 AM , Masséna began moving Jean - Baptiste Meynier ' s division forward in two columns to attack the 3 , 000 defenders . On the right , Jean Jacques La Salcette had 1 , 800 troops including the 17th Light Infantry Demi - Brigade . In the center , Masséna took personal control of 2 , 600 men of the 14th and 32nd Line Infantry . On the left , Amédée Emmanuel Francois Laharpe took his division to the west bank of the Bormida di Spigno and unlimbered six guns to support the attack . When La Salcette ' s flanking column began to threaten the Austrian left flank about 3 : 00 PM , Masséna waved his men forward to attack Dego from the south . Laharpe formed his division into three columns and sent his men across the river north of Dego to attack the Austro - Piedmontese right flank . Causse led two battalions of the 51st Line Infantry on the right flank , Jean - Baptiste Cervoni led one battalion of the 75th Line Infantry in the center while another battalion of the 75th advanced on the left . Henri Christian Michel de Stengel covered the left flank with two regiments of cavalry . The French attack relentlessly forced the defenders into retreat . When the Austrian wing commander Eugene - Guillaume Argenteau belatedly showed up with two battalions of reinforcements , the French simply brushed him aside . In all , the French captured 16 guns , four colors , and as many as 1 , 500 prisoners . That evening the hungry French soldiers went completely beyond the control of their officers and dispersed in search of food and plunder . Meanwhile , Laharpe ' s division was ordered away on another mission . It rained all night and at 7 : 00 AM on 15 April an Austrian brigade under Josef Philipp Vukassovich attacked Dego . After battling for three hours , some key officers were hit and the French position unraveled . By 11 : 00 PM , Vukassovich was in full possession of Dego and several hundred French prisoners . Masséna rallied his routed troops while orders of recall went to Laharpe . When Laharpe ' s grumbling soldiers returned , the French had to attack Dego in a replay of the previous day ' s action . Under his command , Laharpe had the 51st Line under Causse and the 4th Light and 18th Line under Victor . Causse ' s attack immediately ran into trouble and he was fatally hit . The 51st Line was driven back and their chef de brigade was captured but later escaped . Ultimately , the French advantage of numbers compelled Vukassovich to retreat . Causse died on 15 April 1796 . A bust of the slain general stands in the Galerie des Batailles at the Palace of Versailles .
