Mihkel Havi’s band of forest brothers fell in combat on 23 June. Different researchers have written about their fate on the basis of documents and recollections. Nevertheless, some questions remain unanswered. How did the enemy get to the forest brothers? Was there a traitor among them? Who was the man among them who was known only by a nickname? Is it at all possible to find answers to these questions now, decades later? The selection of relevant documents of Soviet state security institutions from archives in Estonia and Russia published here answer all these questions thoroughly and precisely.
