The Battle of Baekgang (Korean: 백강 전투; Hanja: 白江戰鬪) or Battle of Baekgang-gu, also known as the Battle of Hakusukinoe (Japanese: 白村江の戦い, romanized: Hakusuki-no-e no Tatakai / Hakusonkō no Tatakai) in Japan, and as the Battle of Baijiangkou (Chinese: 白江口之战; Chinese: 白江口之戰; pinyin: Bāijiāngkǒu Zhīzhàn) in China, was a battle between Paekche restoration forces and their ally Yamato Japan against the allied forces of Silla and Tang China. The battle took place on 27–28 August 663 (of the Lunar calendar; 4–5 October 663 of the Julian calendar) in the Baengma River (Korean: 백마강; Hanja: 白馬江) or Baek River (Korean: 백강; Hanja: 白江), which is the lower reach of the Geum River in Jeollabuk-do province, Korea. The Silla-Tang forces won a decisive victory, compelling Yamato Japan to withdraw completely from Korean affairs and crushing the Paekche restoration movement.
