The name Nikolai Pavlovich Simonyak is closely connected with the Red Army's successes in the Battle of Leningrad. In the winter of 1943, when the blockade was punctured, his 136th Rifle Division was fighting in the main assault, and its actions brought greatest success to the Red Army on January 12th. Here is where N.P. Simonyak earned the nickname "General Breakthrough".
Before the Breakthrough
Way back during the defense of the Hanko peninsula in 1941, Simonyak thoroughly built up a functional staff, a rare occurrence among Red Army commanders in the early war. This was noticeable in how the journals of the 8th Independent Rifle Brigade and then division which Nikolai Pavlovich commanded. Even in the battles of August-September of 1942 that ended poorly for the Red Army, his division, fighting in the 55th Army, probably performed better than any Soviet unit at Leningrad.
In November of 1942, Simonyak's 136th division was taken out of the 55th Army to the front reserve. The troops were busy with training. Everyone understood that a new breakthrough attempt was coming, and there was a lot to do before it could be successful.
