If on these excepted matters they could not agree between themselves, twelve arbitrators were to decide according to the sworn evidence of the men of the lands in question.[91] All immediate danger of interference from either Louis or the Legate being thus removed, Henry summoned the Norman host to meet at Argentan on October 9 for an expedition against the rebels in Berry.[92] Young Henry and Richard had, by his desire, joined him on his arrival in Normandy;[93] the former was now despatched in advance into Berry, and when the king’s host reached the Norman border at Alençon Richard was detached from it and once more sent into Poitou “to subdue the enemies” there, while the king himself marched upon Châteauroux. After receiving its formal surrender he proceeded to La Châtre; this place, and the little Lady of Déols, were also given up to him at once. Thence he proceeded into the Limousin and called upon those of its nobles and knights who had taken part in the rebellion of 1173 to give an account of their conduct; one of the most important of them, the viscount of Turenne, surrendered his chief castle, “strongly fortified by both art and nature”; with the others Henry dealt “according as each of them deserved.”[94] He then hurried back to Graçay in Berry, to meet Louis and the commissioners who were to report to the two kings the result of their investigations about Auvergne. What that result was we are nowhere directly told; we only hear that both the rivals declared themselves content to abide by it.[95] The next reference to the overlordship of Auvergne, however, some twelve years later, seems to indicate that the commissioners gave their award in favour of the duke of Aquitaine.
