At this time, the German army was already exhausted, and the constant retreat had severed their connection with the Austro-Hungarian First Army Group.
As the First Army Group of the Austro-Hungarian Empire tried to support the German army in the war, they accidentally entered the heavy encirclement of the Russian army, resulting in heavy losses and the entire Army Group being crushed.
To quote Rudolf, "The order to retreat was given on the 11th, but this retreat was completely involuntary. Our situation has become extremely critical, and it now seems that the Russian army is about to invade Poznan, Cilicia, and the Moravia region."
