On 29 July, the brigades of Peter Ott and Joseph Ocskay seized the towns of Gavardo and Salò, forcing Sauret to pull back to Desenzano del Garda with the loss of 500 men and two cannons. However, Guieu and 400 soldiers barricaded themselves in Salò's Palazzo Martinengo and refused to give up. The following day, Johann von Klenau surprised Brescia, cutting Bonaparte's supply line to Milan. Reacting to the loss of his base of operations, the French army commander began shifting his main strength to face Quasdanovich, while Augereau observed the main Austrian army under Dagobert von Wurmser. On 31 July, Sauret marched to Salò, defeated Ocskay's troops in a fight lasting several hours, and rescued Guieu and his men. Though, he quickly pulled back to Lonato del Garda, the defeat prompted Quasdanovich to regroup his troops at Gavardo. Sometime during 1 August, Sauret was injured and Guieu took command of the division. After an intricate series of actions, the Battle of Lonato on 3 August resulted in the defeat and withdrawal of Quasdanovich. Sauret's division, still under Guieu, observed the retreat of the Austrian Right Column and missed the Battle of Castiglione on 5 August.
