He justified his rapid progress and reputation when, at the Battle of Rivoli, he spurred ahead with the entire cavalry—26 horsemen of the 22nd Horse Chasseurs.
A battery of 15 French guns blasted the Austrian dragoons, while two columns of infantry were led forward supported by cavalry under Charles Leclerc and Lasalle.
The packed Austrian soldiers in the gorge fled when their own dragoons began trampling on them in panic.
As a result, an entire battalion of the Deutschmeister Regiment threw down its arms in panic and fled.
Likewise, the dispersed infantry on the Trambasore Heights were unable to hold once Lasalle and the French cavalry got in their midst.
Lasalle and his men continued to support Generals Lebley and Vial until the battle was over.
There were 5,000 French casualties and 14,000 Austrian casualties.
Eleven flags were captured, five of which were captured by Lasalle.
After the battle, all of the trophies were piled up before Napoleon and Lasalle lay exhausted a few feet away on top of his five flags.
Napoleon said, "Go to sleep on your flags, Lasalle, for it was well-deserved!”

With 16 men from the new Corps of Guides, Lasalle charged the enemy's Uhlans, forcing them to evacuate the city and retreat to the Tagliamento.
Lasalle was the first to cross the river in pursuit of them.
Lasalle and his men successfully drove the enemy out of the Tagliamento, ending the campaign in Italy with an overwhelming French Victory.
