Hans-Ulrich von Krantz’s book is devoted to the most gripping and mysterious of the projects of the Hitlerite empire. It is about the creation of secret bases in Antarctica—bases that, the author is convinced, exist to this day. When Germany began to suffer defeat in the Second World War, the Nazi leaders started laying the groundwork for the coming Fourth Reich. With the help of submarines, specialists and materials to build a secret base were delivered to Antarctica. Later, in the 1960s, an American military expedition was sent there, the results of which were strictly classified. What were the Nazis building in Antarctica? And what did the Americans find? This is what Hans-Ulrich von Krantz’s book is about.
