Baekje forces attempted a brief restoration movement but faced Silla-Tang joint forces. A Buddhist monk Dochim (도침, 道琛) and the former Baekje general Buyeo Boksin rose to try to revive Baekje. They welcomed the Baekje prince Buyeo Pung back from Japan to serve as king, with Juryu (주류, 周留, in modern Seocheon County, South Chungcheong) as their headquarters. They put the Tang general Liu Renyuan (劉仁願) under siege in Sabi. Emperor Gaozong sent the general Liu Rengui, who had previously been demoted to commoner rank for offending Li Yifu, with a relief force, and Liu Rengui and Liu Renyuan were able to fight off the Baekje resistance forces' attacks, but were themselves not strong enough to quell the rebellion, and so for some time the armies were in stalemate.
