Haye de Silz succeeded him as general. Boulainvilliers foolishly returned a few months later in the Morbihan. He was captured and shot by Pierre Guillemot's men. Other départements, however, were not as united as the Morbihan. In the north of Anjou, Marie Paul de Scépeaux de Bois-Guignot was named commander for the north of Maine-et-Loire. His authority later extended to Loire-Atlantique, Mayenne and Sarthe. However, he commanded in name only since like in other départements, his authority as a Chouan chief only extended to his own canton. Joseph de Puisaye, a former officer who was compromised in the federalist revolts, realised the necessity of centralised command and attempted to assume the function of general-in-chief of the Chouans. Recognised by some chiefs, Puisaye embarked from Dinard to London on 11 September 1794 to meet future King Charles X of France. Major-General Pierre Dezoteux de Cormatin, his second-in-command, assumed command in his absence. Charles X favoured absolute monarchy and distrusted Puisaye, who advocated parliamentary monarchy. However, after the intervention of British Prime Minister William Pitt the Younger, Puisaye was appointed general-in-chief of the Royal and Catholic Army of Brittany on 15 October 1794 with the rank of lieutenant general, thus entrusting him with the king's authority. His power thus extended to all the insurgent areas north of the Loire, including the Maine and Anjou, where Scépeaux appointed him general-in-chief. When Maximilien de Robespierre fell on 28 July 1794, the Terror ended and the Convention nationale became more flexible and open to negotiation. The Agence royaliste de Paris asked the Chouans in the name of Louis XVIII of France, then count of Provence, to stop fighting. On 26 December, Brigadier General Jean Humbert and the Chouan chief Boishardy met to discuss peace options. Puisaye tried to organise a landing from London, and his lieutenant, Cormatin, assumed full command and negotiated the peace treaty of La Mabilais in April 1795. He was followed by a few local leaders. Of the 121 leaders attending, only 21, including de Silz and Boishardy, signed the treaty. Second phase 1795–1796 Because neither side had negotiated in good faith, tension again increased following the death of Louis XVII on 8 June. The peace was broken on 26 August 1794 by General Lazare Hoche, who succeeded Jean Antoine Rossignol as head of the Army of the Coasts of Brest and ordered the arrest of those who had refused to sign
