This book is an edited translation of the Soviet Staff study of the Red Army's Belorussian operation in the summer of 1944, which was unprecedented in terms of its scale, scope and strategic consequences. The Soviet Stavka had planned a campaign consisting of a series of massive operations spanning the entire Soviet-German front. Four powerful fronts (army groups) operated under close Stavka (high command) control. Over 1.8 million troops accomplished a feat unique in the history of the Red Army: the defeat and dismemberment of an entire German army group. This book is a translation of the Soviet General Staff Study No 18, a work originally classified as secret and intended to educate Soviet commanders and staff officers. The operation is presented from the Soviet perspective, in the words of the individuals who planned and orchestrated the plans. A map supplement, including terrain maps, is provided to illustrate the flow of the operation in greater detail.
