The author offers this book as a monument commemorating the events of the years 1940-1945, commemorating Nazi bestiality, Nazi sadism, Nazi inhumanity and the death of their six million innocent Jewish victims. Every individual story, every picture, every description is but a stone in that monument which will stand forever to remind the world of this shameful phase of history, and to ask of it vigilance, lest the events of these years be repeated.
