On 1 May, Archduke John ordered his army to withdraw to the east. In several clashes on 2 May, the Austrian rear guard held off the French, inflicting 400 killed and wounded including Debroc wounded. Austrian losses were only 200 killed and wounded, but the French rounded up an additional 850 stragglers and sick. The Austrians paused on the Brenta River until 5 May, then continued retreating to the Piave. Eugène followed while sending the division of General of Division Pierre François Joseph Durutte along a more southerly route in order to relieve the blockade of Venice. When he reached that city, Durutte was reinforced by 4,000 troops from the garrison and marched to join Eugène on the Piave. The Light Brigade having proved too weak to pursue effectively, Eugène strengthened it into a Light Division by adding three additional "voltiguer" battalions, attaching an entire cavalry regiment, and boosting its artillery complement to four cannons. Replacing Debroc, the French army commander gave the Light Division to General of Brigade Joseph Marie, Count Dessaix.
