After the first defeat of the Russian army, there was a second battle at the Masurian Lake in 1915. This battle is also called as the winter battle of the Masurian Lake, because during the battle, there was a big blizzard. It was part of Paul von Hindenburg, a German commander’s plan to push Russia on two sides by combining Germany and Austria force. His aim is to end the war at the Eastern Front, the plan work and Russia finally surrenders at 21 February 1915.

In my opinion, Russia should have prepared for the war better since they are the one who lives in the cold all time, they shouldn’t have know that how cold would it be in a long fight, I think that if the Russian army had prepared better, they could have repel the German attack.
