How did Dumouriez’s defection to Austria deepen the conflict between Georges Danton and the Girondins?

Following the defeat of the French army at Neerwinden in March 1793, General Charles-François du Périer Dumouriez defected to the Austrians. This event served as a catalyst that made the existing tensions between Georges Danton and the Girondins irreparable.12

The Girondins, who had previously been associated with Dumouriez, attempted to deflect blame by accusing Danton of complicity in the general's treason. Danton responded by aggressively turning the tables and leveling the same accusation against the Girondins. This mutual exchange of treason charges deepened the political divide, ultimately contributing to the downfall of the Girondin faction, as their association with the disgraced general discredited them and provided the Jacobins and Montagnards with the political leverage to have them expelled from the National Convention on June 2, 1793.123
