Квантунская армия
On 18 September 1931, a bomb was secretly planted on the tracks of the Japanese-controlled Southern Manchuria Railway by Kwantung Army elements. Charging that Chinese soldiers had attacked the rail line, Ishiwara ordered Japanese troops to seize the Chinese military barracks in the nearby city of Liutiaokou. He then ordered Kwantung Army units to seize control of all other Manchurian cities without informing the new commander-in-chief of the Kwantung Army, General Shigeru Honjo, or the Imperial Japanese Army General Staff in Tokyo.
