Eight-Day War

The Eight-Day War, also known as the September War, the Kayos Campaign and the First Sentanese War, was fought between 19 to 27 September, 1950 by Kadsreius Sentanese Republic (with support from Mahri,, and ) and the Sentanese Empire (with support from the Vicnoran Kingdom and ).

Background
Kadsreius Sentanese Republic was created in 1940 during the Second World War, after Hiroshi Kayos was exiled from the Sentanese army after attempting to transform Sentan from an imperialist monarchy into a republic.

On July 4, 1950, Kayos arrived in Abeta to see the then-president of Takuya Akiyama. KSR and Mahri signed the non-aggression pact, meaning Mahri will aid and join with the KSR in the war against Sentan and Vicnora.

Course of the war
On September 17, 1950, Kayos sent around 5,000 troops to Mahri, where they joined with the Mahri troops. They went on 12 boats carrying around 10,000 troops, with 4 LSTs carrying 8 tanks each.

On the morning of September 19, 1950, Mahrian and KSR troops arrived at the western section of the northern island of the Sentanese Empire via boat behind the artillery fire.

On the same day, then-prime minister of the Sentanese Empire, Hiroto Hisakawa, was in the meeting with the then-prime minister of Sweden Tage Erlander in Stockholm. He was informed the KSR and Mahri launched the surprise attack on the empire. Erlander agreed to launch Swedish troops to the El Kadsreian Islands to help Sentan push back the KSR and Mahrian troops in the northern island of the Sentanese Empire.

The supporting countries Yugoslavia, Venezuela, and Sweden arrived 3 days later. Yugoslavia was acting on behalf of Kayos, but did not agree with some of his opinions, and Venezuela was sent as backup due to their strong stance as an ally of the countries outside South America.
