Next he attacked a second one and ran out of ammo. Then he was hit in the right leg. At the same moment he noticed that his wingman was attacked by a Messerschmitt. Sorokin came in to help. He rammed the tail of the enemy plane with his propeller. This caused a belly landing of the Messerschmitt. However the Sorokin’s fighter was out of service as well. It required big efforts that Sorokin could land his hit plane on a frozen lake. The rammed "Messerschmitt" landed on the same lake just 300 m away. A big dog jumped out of the Messerschmitt and moved in the direction of Sorokin’s plane. Sorokin killed the dog with two shots. Next Sorokin noticed the German pilot who was approaching to him, so he shot him too. In same time the second German came from the opposite side and hit Sorokin in the face with a knife and pulled him down.
