Yamato period
In 660, Baekje was attacked by the allied armies of Silla and Tang dynasty China. The capital, Sabi, was taken, but Boksin resisted near modern-day Yesan. After King Uija's surrender to Tang dynasty]] China, Boksin and the monk Dochim kindled a restoration movement. They sent for the prince Buyeo Pung, who had been living as a hostage in Yamato period Japan, an important Baekje ally. With some Japanese aid, they gathered the remnants of the Baekje army and launched a series of attacks on the Silla-Tang forces.
