The monograph is devoted to the analysis of the activities of state, military bodies and public organizations of Western Siberia to mobilize all forces and means to prepare for the approaching war. On the fronts of World War II, Siberians became a symbol of unbending resilience, courage and heroism and military skill. They coped with all the combat tasks assigned to them with honor, personifying the best features of Russian soldiers. To a large extent, this was the result of their preparation in the pre-war period. The book can be useful for scientists, faculty, graduate students, students, as well as for everyone interested in the military history of Siberia and Altai.
