Oyashima Armistice

The Oyashima Armistice, also known as the Wanshu Bay Armistice, was an armistice signed between Imperialist Yamatai and the Escaric Allies on 15 July 1944 during the Second Escar-Varunan War. The armistice ended all fighting between the Allies and Yamatai, but did not involve Arshavat or Kuiju, the latter of which was allied with Yamatai in the Niihama Pact. The armistice was signed on the Yamataian battleship Oyashima, which was at the time anchored in Wanshu Bay. It came into force at 6 pm Wanshu time on 15 July 1944 and marked a victory for the Allies over Yamatai, but was not a formal surrender. Yamatai would later formally surrender to the Allies and officially end the war during the 1949 Treaty of Eito.

Immediately after the armistice agreement, the Wanshu Post-War Conference was carried out between 18 and 25 July, where Yamataian reparations, repatriation of Yamataian troops and personnel in Allied-occupied areas, formal partitions of Hinomoto and Qieli between Yamatai and Allied-occupied zones, agreements on joint operations in Nanyokuni against Arshavat, and other topics were negotiated. Once news of the armistice was released, Kuiju formally withdrew from the Niihama Pact and denounced Yamatai as traitors.

Fighting between the Allies and Yamatai continued up to 6 pm of 15 July, with 1,872 people dying on the last day of the war. The last person killed prior to the armistice is believed to be Private Omura Kayo of the Yamatai Imperial Army's 48th Infantry Division, who was shot on Hinomoto just two minutes before the armistice came into effect.
