France radicalized more and more, and the "Feuillants" lost their influence to the "Girondins" and the rising Jacobins. D'Averhoult nevertheless spoke out against the illiberal measures that were taken, like the reintroduction of internal passports, and the lawlessness of the Paris Mob. For instance, he spoke out against the lawlessness of the "Journée de 20 juin", even in vain demanding the sanctioning of the local authorities who had failed to suppress that riot. But external developments made his position untenable: the Prussians entered the war after issuing an maladroit ultimatum, in which they demanded the reinstatement of the king in his old powers (reminiscent of the demand to reinstate the stadtholder in September 1787). In the following furor d'Averhoult on 26 July announced that he resigned as deputy in the Assembly. He took a commission as Colonel of the 7th regiment of dragoons, and departed for the front in northern France.
