prevent this. On 21 September, Petion, Barbaroux and the others abandoned Brittany, sailing from the port of Lanvéoc to Bordeaux, where they intended to continue their struggle. The Convention sent Jean-Baptiste Carrier to Rennes to re-establish order. He arrived on 1 September and remained until 5 or 6 October, when he left for Nantes. In the intervening five weeks he rallied the local Jacobins and comprehensively purged Federalists, Girondins and monarchists from every public office. There were no executions under his command, although counter-revolutionaries were locked up in various local prisons - the most dangerous among them being confined to Mont Saint Michel for maximum security - and others were sent to Paris for trial. He waged a particularly intense campaign against the local clergy, and had plans for a "noyade" (mass drowning) as he was later to undertake at Nantes, but he could not put his plan into effect because any vessel leaving St. Malo would have been easily captured by the British fleet which was standing out to sea, imposing a blockade. After Carrier's departure, his replacement :fr:François-Joachim Esnue-Lavallée released most of the people he had imprisoned. Early in 1794 a new revolt, the Chouannerie, broke out in Brittany and nearby départements. Lyon Lyon was the second-largest city in France after Paris, where factional tension ran very high in the first half of 1793. As in Marseilles, most of the sections supported the Girondins, but a small and determined group of Jacobins was intent on taking power in the city under their charismatic but divisive leader, Joseph Chalier. On 9 March the Jacobins effectively gained control of the city. On 29 May a meeting of the sections decided to replace the Jacobin Council government. :fr:Jean-Pierre Gauthier and :fr:Pierre-Claude Nioche, représentants en mission from the national government, arrived and were placed under guard. During the night Chalier's partisans were arrested and the following day a man named Coindre became mayor. Chalier and his friends were put on trial. In the days following the arrest of the Girondin deputés in Paris, the Convention saw developments in Lyon as part of a more widespread revolt threatening the authority of central government. Indeed, within the month the municipal leaders in Lyon were linking up both with neighbouring departments and with other "insurgent cities" in the French south, Marseille, Nîmes and Bordeaux. Lyon now called for a meeting among the potentially separatist municipalities
