This book is a continuation of the acclaimed “Arctic Secrets of the Third Reich.” It is based on documentary materials and memories of direct participants in the events. You will learn about how the development of the Northern Sea Route began; why everyone knew about the beginning of World War II except the Soviet Union; what the Nazis did in the Barents Sea and where the uninvited guests came from in the Soviet Arctic; who are the ocean “werewolves” and what did they do along the Northern Sea Route; as well as about the Arctic odyssey of captain-Zurzee Robert Eissen and the last journey of the Komet raider. The Soviet Arctic has been keeping its secrets for more than 60 years, reliably hidden by an ice cover. But the time has come for the declassification of archival documents, which allows us to take a fresh look at the history of the war years.
