In 1941-1942, Nikolai Aleksandrovich took part in the "great migration of peoples" as part of the evacuation from the frontline territories of the USSR. "In the winter of 1942, we created a women's tractor brigade from evacuated Ukrainian girls...

My main task was to repair equipment. From morning until late evening, I raced on horseback from tractor to tractor to run them." In this situation, Nikolai did not forget that "the fleet was waiting for him." Without reporting to the leadership, he walked to Engels. Then there were many more cities and stops on the way, until Nikolai reached Krasnodar, where he was sent to study at the electromechanical school named after sailor Zheleznyakov. Due to the bombing and shelling, there was little study.

"In November 1942, many of us were discharged into the Marines - they were preparing to break the siege. Participated in the explosion. The battalion arrived in Shlisselburg mortally exhausted. In the defense on the Nevsky Pyatachok, he was the commander of a mortar crew, and from the spring - the commander of a reconnaissance platoon division."

In early June 1943, their reconnaissance platoon was tasked with finding out the intentions of the Germans in the Nevskaya Dubrovka area. On the night of June 15, in the "neutral zone", when the division had advanced deep into the German position, Belolipetsky stepped on a mine. His right leg was amputated in the hospital. He was discharged only in January 1944. Wounded, shell-shocked, weakened.
