Infantry of Stalin in the Winter War: To bypass the Mannerheim Line

About 95% of those who died on the Karelian Isthmus in December 1939 - the first month of the Winter War - the Red Army military personnel falls on the Rifle troops. There is no doubt that in the subsequent battles of that war the main losses, the Soviet infantry suffered the main losses, because from the 166 rifle divisions of the Red Army in battles with our northern neighbor 52 took part.
The famous military historian debunks one of the main myths of the Soviet -Finnish war - the idea that the fighting went only on the Mannerheim line firmly rooted in the mass consciousness. Soviet propaganda made a "line" insurmountable, and a logical question arose: why did the Red Army simply not bypassed Finnish fortifications? In fact, such attempts were repeatedly made by the Soviet command. The actions of the Red Army when going around the Mannerheim line, in detail on the basis of archival materials, are examined in detail in this book on the example of the 43rd, 56th, 75th, 155th rifle and 25th motor-cavalry divisions (56 -I and the 75th rifle divisions with their artillery were the best military units of the 8th Army, and the 25th Moto-Cavalry Division was considered heroic) A thorough analysis of documents allowed the author to finally answer the question of why, despite all the Titanic efforts spent, turned into a collapse, but also significant losses of the Soviet troops to get around the Mannerheim line
