The chronicler of this book was an eyewitness of the last 30 days of the military leadership of the Third Reich. This war diary of the high command of the Wehrmacht and the report of the Battle for Berlin present the final phase of the war as seen daily by the official recorder of the war diary of the supreme command of the German forces. The value of this record lies in the reliable chronological recording and objective observation of an historical epoch unique in its revolutionary consequences. The reader is a witness to the dramatic events in the headquarters and in Berlin. Until the bitter end, the common staff remained the German command authority and was employed by the allies even after the capitulation. The structure of the records, with their sequence of possibilities, hopes, limitations and illusions, is scientifically explained in the introduction by historian Professor Walther Hubatsch.
