[2] Peace was obtained briefly by Hugh's marriage to Audéarde or Aldiarde, the daughter of the viscount Ralph of Thouars.
[2] Hugh also engaged in a long war with Aimery I, lord of Rancon, who seized Civray, a fief of Bernard I of La Marche.
On 6 March 1025, Hugh exchanged lands with the abbey of Saint-Hilaire of Poitiers in order to found a monastery for his soul.
Hugh and the Poitevin bishop Isembart then sent letters to Pope John XIX to beg exemption for his monasteries from all authority save that of Nouaillé.
At his monastery of Notre-Dame de Lusignan, a monastic chronicler wrote the Conventum inter Guillelmum ducem Aquitaniae et Hugonem Chiliarchum celebrating Hugh's warmaking.
