In 1321, Aymon oversaw the siege engines at the siege ofCorbières. On the death of Amadeus V in 1323, Aymon was lord of Bresse under Edward. As a younger son of a noble family, Aymon had planned on a life in the church. When Edward died in 1329, Aymon was in Avignon at the court of Pope John XXII. In 1329, shortly after becoming count, Aymon established a committee to settle the territorial disputes with his cousin, Amadeus III of Geneva. These disputes had been an ongoing feud between the families for generations, but they were able to resolve them through years of negotiations without resorting back to war. This was how Aymon earned his nickname of 'The Peaceful'. He contested the title Count of Savoy with his niece, Joan of Savoy since Savoy operated under Salic law and had never had a female ruler. Joan with the support of her husband, John III, Duke of Brittany defended Joan's claim. John and Joan had no issue. Eventually a settlement was reached whereby Aymon obtained the Countship in return for providing a monetary payment to Joan. He spent much of his first few years as count at war with the Dauphin, Guigues VIII of Viennois, continuing a feud which went back for generations in their families. After Guigues was killed besieging La Perrière in 1333, Philip VI of France was able to broker a truce between Aymon and the new Dauphin, Humbert II of Viennois, brother of Guigues. In August 1334, in the buildup to the Hundred Years' War, Edward III of England sent an embassy to Aymon to convince him to join the impending conflict on the side of the English. Aymon declined to commit, as he held lands both in England and in Normandy, so was technically a subject of both kings. In April 1337, Philip sent similar messages on the other side. Aymon replied that he could not go abroad to fight as he still had territorial disputes with the Dauphiné. Philip quickly settled a more lasting peace, as Humbert was trying to sell the Dauphiné. Aymon then led his forces as part of the French war effort from 1339 to 1342. He often fought alongside Amadeus III of Geneva. In 1330, Aymon established a chancellor's office to manage official documents. He financed the expansion of a burial chapel at the Hautecombe Abbey which was constructed from 1331 to 1342. In 1340, he set up judges to specifically handle appeals at a level between the castellans and himself, to ease his workload in such cases.
Marriage and Children
Prior to his marriage, Aymon also fathered several illegitimate children, who were raised in his household, even after his marriage. These included:
Humbert, who worked for his father, and later his brother the count.
Ogier, who worked for his father
