関東軍
The Imperial Japanese Army Headquarters did not immediately communicate the cease-fire order to the Kwantung Army, and many elements of the army either did not understand it, or ignored it. Hence, pockets of fierce resistance from the Kwantung Army continued, and the Soviets continued their advance, largely avoiding the pockets of resistance, reaching Mukden, Changchun, and Qiqihar by 20 August. The cease-fire order was eventually communicated to the Kwantung Army, but not before the Soviets had made most of their territorial gains.
