Why did the Girondins accuse Georges Danton of responsibility for the September Massacres?

The Girondins, who represented the moderate wing of the French Revolution, accused Georges Danton of responsibility for the September Massacres as part of the intense political rivalry within the National Convention.12

While there is no evidence that Danton organized the killings, he was a prominent leader in the provisional government at the time and did nothing to stop the violence. The Girondins, who were deeply hostile toward the militancy of the Paris Commune and the radical factions of the Revolution, used the massacres as a political weapon to discredit their radical opponents, including Danton, Jean-Paul Marat, and Maximilien de Robespierre. This accusation was one of many instances of bitter factional infighting that characterized the period, as the Girondins sought to challenge the influence of the Montagnards and the radicalized Parisian populace.123
