for the Papacy in 1362, and the latter made several attempts to frustrate Aymon's marriage to Joanna. Guy's proposed marriage was, however, deeply opposed by the dominant court faction and the populace generally, as it was thought it would jeopardise a final peace with Sicily. The proposed marriage to Joanna fell through, as did her proposed union with Frederick. In his will Aymon arranged the repayment of a debt of 1,400 ducats to Pierre d'Ameil, who as Archbishop of Naples had supported his project, and who had become Archbishop of Embrun as a reward from Aimon's brother, the Antipope Clement VII. Piere d'Ameil's letters, many containing coded passages, are the principal source for Aimon and Joanna's romance. On 23 May 1366, shortly before leaving on Crusade, Aymon made a written agreement to marry Margaret, eldest daughter of the late Henri de Joinville, Count of Vaudémont, but the marriage never took place because of his death. Crusade and death Although in 1364, when the Order of the Collar was formed with Amadeus III of Geneva as a member, the count made a promise to go on the crusade, he was unable to fulfill it personally due to ill health, and sent his son Aymon in his place.

He joined Amadeus of Savoy's army at Venice in June that year, along with some mercenary companies and a host of Burgundians. The crusader fleet totalled some fifteen vessels, including six Venetian galleys. Aymon, "the lord of Geneva" (monsieur de Genève), was named "admiral" of one of the galleys. On 3 January 1366 Amadeus had made up his will in case of his death overseas, naming as his heirs general first his son (and his issue) and then his second cousin's younger children, Amadeus and Louis, and finally to Aymon of Geneva on the condition that he adopt the name and arms of the house of Savoy. This will never went into effect, since Amadeus returned alive, and Aymon predeceased him anyway. The crusade was not ultimately successful in dislodging the Turks from Europe, but it did remove them from Gallipoli and free the Emperor John V Palaiologos from the Bulgars. Aymon, "[having] distinguished himself by his bravery", returned with the Crusade to Venice on 29 July 1367. There he remained for two weeks, possibly ill or
