Sakanoue no Tamuramaro
In 801, Sakanoue no Tamuramaro began a new campaign against the Isawa Emishi having moderate success. Finally on 15 April 802 the Emishi leaders More and Aterui surrendered with some 500 warriors. The captives were taken to Kyoto for an audience with the emperor and beheaded at Moriyama in Kawachi Province against the wishes of General Sakanoue. This act of cruelty enraged the Emishi leading to another twenty or more years of fighting.
