In 663, Baekje revival forces and a Japanese naval fleet convened in southern Baekje to confront the Silla forces in the Battle of Baekgang. The Tang dynasty also sent 7,000 soldiers and 170 ships. After five naval confrontations that took place in August 663 at Baekgang, considered the lower reaches of Geum River or Dongjin river, the Silla–Tang forces emerged victorious, and Buyeo Pung escaped to Goguryeo.
