Goguryeo–Yamato War

The Goguryeo–Yamato War occurred at the end of 4th century and the beginning of the 5th century between Goguryeo and Yamato era Japan. After this war, Goguryeo made both Silla and Baekje its subjects, bringing about a unification of the Korean Peninsula that lasted about 50 years.

Timeline

• In 396, Gwanggaeto the Great led his troops and attacked Baekje, conquering many castles along the way. Gwanggaeto captured the Baekje capital and forced King Asin of Baekje to surrender and become a subject of Goguryeo. Gwanggaeto gained 58 towns and 700 villages, and triumphantly returned home with a hostage Baekje prince and several ministers.
• In 399, Baekje broke their previous allegiance to Goguryeo and allied with Wa. In Pyongyang, Gwanggaeto received a Sillan envoy who notified him that Baekje and Wa troops were crossing the border to invade Silla, and requested Goguryeo for aid. As Silla was a loyal subject of Goguryeo, Gwanggaeto agreed to save them.
• In 400, Gwanggaeto the Great sent 50,000 soldiers to save Silla. As Goguryeo troops reached the Silla capital, the Wa army retreated toward Gaya. The Goguryeo and Silla alliance attacked and pursued the Wa forces to the castle in Alla where the Japanese surrendered.
• In 404, Yamato unexpectedly invaded the southern border of the former Daifang territory. Gwanggaeto led his troops and demolished the Yamato forces in the vicinity of Pyongyang. The Japanese army was utterly defeated and countless numbers of Japanese soldiers were killed.
