 However, as the Chinese still had the bulk of their troops in the northern Korea, for the Japanese the military situation required an immediate deployment of reinforcements to Korea.Since the main objective of the Japanese was the Chinese forces concentrated at Pyongyang, they had four routes on which to deploy their troops to Pyongyang; one through via Chemulpo, another through Pusan, one from Wonsan on the eastern coast of Korea or by landing directly at the mouth of the Taedong River in the immediate vicinity of Pyongyang.Since the Japanese were hard pressed for time, as part of their strategy they needed to drive the Chinese troops from Korea before winter to avoid prolongation of military operations.
