Thus the struggle within the Convention continued without results. The decision was to come from outside. Since the king's trial, the sans-culottes had been constantly assailing the "appealers" ("appelants"), and quickly came to desire their expulsion from the Convention. They demanded establishing a Revolutionary Tribunal to deal with supposed aristocratic plots. Military setbacks from the First Coalition, Dumouriez's defection to the enemy and the war in the Vendée, which began in March 1793, were all used as arguments by Montagnards and "sans-culottes" to portray Girondins as soft. They demanded that the Girondins take measures, but the Girondins were reluctant to adopt the proposed measures. The Girondins were forced to accept the Montagnards creation of the Revolutionary Tribunal and a Committee of Public Safety. Social and economic difficulties exacerbated the tensions between the groups.
