In this book, the authors decided to figure out what actually happened to the repeatedly slandered and slandered Tukhachevsky. And they did this on the basis of exclusively archival documents. Whatever direction the marshal’s activities took, the authors always received information radically opposite to that which has been published for many years. Among the accusations against M. N. Tukhachevsky, there is not a single one that corresponds to reality. The conclusions that the authors made in this book not only debunk the existing false stereotypes, but also give the right to consider a number of accusations against M. N. Tukhachevsky ordinary lies.
