At the Jacobin Club and in the National Assembly he denounced what he called their campaign of panic and lies.” On 10 August he was made Commissar of the Army of the Midi with Lacombe-Saint Michel and Rouyer.

[2] On 3 January 1793, he made a speech in the Convention denouncing the leading Girondins, Guadet, Gensonné and Vergniaud for treason by dealing secretly with the king in July 1792, using the painter Joseph Boze as an intermediary.

He was there when Charles François Dumouriez went over to the Austrians with the young duc de Chartres, son of Louis Philippe d'Orléans, and took all necessary measures to respond to the gravity of the defection.

[7] In response Gasparin wrote from Lille to both the Committee of Public Safety and the Convention, summarising his loyal work as représentant en mission and his military achievements.

On 16 June, before leaving for the Vendée, he proposed a decree imposing the death penalty for French citizens and foreigners alike found guilty of spying in war zones or in the armies, which was adopted by the Convention.

During the voting on 10 July to determine who should next serve on the Committee, Gasparin was retained - the sole career soldier on it at that time - even though under Danton's leadership, its conduct of the war was heavily criticised.

The following day however he resigned, mentioning that he had very serious health problems - earlier in the year he had been obliged to give up his mission to the Army of the North because of a severe case of swollen glands and pain in his sides.

Napoleon read aloud to them from his pamphlet ”Le souper de Beaucaire” and the representatives of the Convention decided to have it printed at Valence at public expense.

[10] In a letter to the Committee of Public Safety, Gasparin and Saliceti recommended Bonaparte to replace the artillery commander Elzéar Auguste Cousin de Dommartin, who had been wounded in combat at the Ollioules gorges.
