On July 21, 1937, the military operations of Australasia officially began.
The Island Nation had a much larger population than Australasia. If the war entered a stalemate, it would lead to many unnecessary losses for Australasia.
Therefore, in formulating the war plan, Arthur requested that the General Staff minimize casualties and end the war as quickly as possible.
The combat plan provided by the General Staff involved about 800,000 troops launching an attack on Kyushu Island in the Island Nation, making beach landings at Nagasaki and Kagoshima.
The remaining 2.2 million troops would launch attacks from Osaka, Nagoya to Tokyo, aiming to attract more Island Nation Army troops to those locations.
From this plan, it was evident that the offensive of Australasia would primarily focus on crucial Islander cities such as Nagasaki, Osaka, Nagoya, and Tokyo.
