Receiving this bad news, Maoqi was not surprised in the slightest. Since he had refused to divide his forces to reinforce Poznan, he had prepared for the worst.
There is an art to taking the blame, and giving up Warsaw isn't as simple as saying it out loud. Without sufficient reason, there would be no way to explain it to the outside world.
At the military conference, Maoqi calmly stated, "Poznan has fallen ahead of schedule, our rear is threatened, and the plan to encircle and annihilate the Third Russian Army and the Sixth Army has failed.
We now have to change the original battle plan, retake the Poznan region first to ensure our lines of communication are open, and then turn back to Warsaw for a decisive battle with the Russians.
