 Amago Hisayuki, however, considered the risks to be too great and spoke out against it, but was derided by Tsunehisa as a coward and publicly humiliated.Hisayuki was given the task of engaging the Mōri's ally, the Shishido clan in Aki as part of an initial and concurrent operation of the larger Amago campaign into Aki.The initial phase of the campaign began in June 1540, which involved an attack by the troops of Amago Hisayuki, his son Masahisa and his nephew Kunihisa on the domain of Motonari's ally, the Shishido clan, a foray that was to prove of little effect except to deny Haruhisa of some of his most capable generals and soldiers for the attack on Koriyama Castle.
