Blanqui, the leader of the most radical faction, established his own headquarters at the nearby Prefecture of the Seine, issuing orders and decrees to his followers, intent upon establishing his own government. While the formation of the new government was taking place inside the Hôtel de Ville, however, units of the National Guard and loyal to General Trochu arrived and recaptured the building without violence. By three o'clock, the demonstrators had been given safe passage and left, and the brief uprising was over.
