The morning of Saturday 14 January found Alvinczi engaging the division of Joubert. He had united three Austrian columns between
Caprino on the right and the chapel of San Marco on the left; the brigade of
Franz Josef de Lusignan was advancing to the north of
Monte Baldo; and the troops of
Peter Vitus von Quosdanovich and
Josef Philipp Vukassovich were pouring down the roads on either side of the
Adige. Before daybreak as the French were moving on the road from
Rivoli to Incanale Joubert attacked and drove the Austrians from the chapel of San Marco. At 9 a.m., the Austrian brigades of Samuel Koblos and
Anton Lipthay counterattacked the French forces on the Trambasore Heights. Another column under Prince
Heinrich of Reuss-Plauen attempted to turn the French right via the Rivoli gorge. Meanwhile, on the French right flank, Vukassovich had advanced down the east bank of the Adige and had established batteries opposite Osteria. The fire of his guns and the pressure from Quosdanovich forced the French out of the village of Osteria and onto the Rivoli plateau. By about 11 a.m. the position of Bonaparte was becoming desperate: an Austrian column under Lusignan was cutting off his retreat south of Rivoli. To reopen his line of retreat Bonaparte turned to Massena's 18th
Demi-brigade ("the Brave"), newly arrived from
Lake Garda. Meanwhile, Alvinczi was on the Trambasore Heights urging his victorious battalions forward, though they were unformed by combat and rough terrain. With the 18th dispatched to check Lusignan, Bonaparte turned all his attention to Quosdanovich. He understood the defeat of this column was the key to the battle. Unfortunately the French had very few reserves left and mostly had to accomplish this with troops already at hand. Making the best of interior lines and his advantage in artillery, Bonaparte thinned out Joubert's lines facing the Austrians frontally at the Trambasore Heights as much as possible and concentrated them before the gorge. A battery of 15 French guns were massed and poured
canister shot at point blank range into the advancing Austrian column that was emerging from the gorge. This devastating firepower struck first on the advancing Austrian
dragoons who broke and stampeded through their own infantry causing mass chaos. At this juncture the brigade of
Charles Leclerc assaulted the column frontally while Joubert laid down heavy flanking fire from San Marco. Here
Antoine Charles de Lasalle with just 26 horseman of the 22nd Horse
Chasseurs charged into the melee. Lasalle's men captured a whole Austrian battalion and seized 5 enemy flags. In the centre the battle was not yet won;
Joseph Ocskay renewed his attack from San Marco and drove back the brigade of
Honoré Vial. But at midday French cavalry under
Joachim Murat charged the flanks of Ocskay's troops, which were driven back to the positions they occupied in the morning. Quosdanovich realized he could not force the defile and ordered his troops to fall back out of artillery range. Meanwhile, while Lusignan was being engaged frontally by the brigade of
Guillaume Brune, the division of
Gabriel Rey, coming up from
Castelnuovo and the brigade of
Claude Victor (reserve) began to arrive. They crushed the Austrian column of Lusignan who fled west with less than 2,000 men remaining. The French lost 3,200 killed and wounded and 1,000 captured, while the Austrians suffered 4,000 killed and wounded, plus 8,000 men and 40 guns captured. Although the number of prisoners can reach 10,000, the total losses exceed two-thirds of the total number of the army. One authority gives the French 5,000 and the Austrians 14,000 total losses. ==Aftermath==
