In late May 1793, the Montagnards in the Convention, meeting in the Tuileries Palace, called for the removal of the Commission of Twelve. The Convention was further radicalized by the call for the removal and arrest of Brissot and the entire Girondin group made by the Sans-culottes in the Parisian National Guard, which had armed with cannons and surrounded the Convention. When the refusal of the Convention to make such a hasty decision was delivered to the National Guard, François Hanriot, its leader, replied: "Tell your stupid president that he and his Assembly are doomed, and that if within one hour he doesn't deliver to me the twenty-two, I'm going to blast it!" Under this threat of violence, the Convention capitulated and on 2 June 1793, Brissot and the other Girondins were arrested.
