 They were to depart from there in groups, heading for the coast of Korea without escort, there the transports heading for Chemulpo would be escorted by warships.The number of transports allowed the Japanese to redeploy no more than 10-15,000 troops to Korea at a time, this was also taking into consideration the fact that apart from soldiers there were substantial numbers of coolies, equipment and supplies to be transported meaning that the Japanese were able to redeploy one brigade at a time.The 10,000 troops (not confirmed) of the Imperial Japanese Army's 1st Army, under the overall command of Marshal Yamagata Aritomo consisted of the 5th Provincial Division (Hiroshima) under Lieutenant General , and the 3rd Provincial Division (Nagoya) under Lieutenant General Katsura Tarō.
