Забайкальский фронт
The 1st Far Eastern Front was to form the eastern half of the pincer movement. This attack involved the 1st Red Banner Army, the 5th Army and the 10th Mechanized Corps striking towards Mudanjiang (or Mutanchiang). Once that city was captured, this force was to advance towards the cities of Jilin (or Kirin), Changchun and Harbin. Its final objective was to link up with the forces of the Transbaikal Front at Changchun and Jilin thus closing the double envelopment movement.
