The history of mankind is full of secrets and mysteries, many of which cannot be explained even by the most severe skeptics. Who and why built Stonehenge, what the Bermuda Triangle hides, how the Dyatlov group died - neither technical progress nor breakthroughs in information technology bring us closer to final answers to these questions. Evgeny Filatov offers his explanation of several mystical cases that are little known to a wide audience. Based on data from public and archival sources, he reconstructs in detail the course of the alleged events and, who knows, perhaps came closest to the real state of affairs. Fantasy, as we know, is sometimes more insightful than any scientific research. The book “The Lost Battalion” is an attempt to unravel the mysteries of history; it will be of interest to all lovers of mysticism and science fiction.
