Early in 1792, following a bitter quarrel with Jean Pierre Brissot over a legal case which Desmoulins had taken up and discussed in several broadsheets, Desmoulins published a pamphlet, "Jean Pierre Brissot démasqué", which attacked Brissot savagely and personally. In it, Desmoulins claimed that the invented verb "brissoter" had taken on the meaning "to cheat," and accused Brissot of betraying republicanism. The case constructed against Brissot in this pamphlet was expanded and used to terrible and destructive effect in Desmoulins' later publication of 1793, "Fragment de l'histoire secrète de la Révolution" (also known as the "Histoire des Brissotins"), in which the Girondist political faction, of which Brissot was a prominent member, was accused of traitorous and counter-revolutionary activities. This "history," produced in response to calls by Brissot and his followers for the dissolution of the Paris Commune and of the Jacobins, contributed to the arrest and execution of many Girondist leaders, including Brissot himself, in October 1793. Desmoulins intensely regretted his role in the death of the Girondists; present at their trial, he was heard to lament, "O my God! my God! It is I who kill them!" He was seen to collapse in the courtroom when the public prosecutor pronounced the sentence of death.
