- People, be vigilant! - warned the passionate fighter against fascism Julius Fucik, executed by Hitler's executioners in 1943. This book also calls for vigilance. It tells about the essence, scope, cruelty and danger of those atrocities that were committed by Hitler's fascism against peoples during the Second World War. Showing how the Nazis destroyed thousands and thousands of children, women and the elderly, how people died in Nazi captivity from hunger and overwork in the death camps - Buchenwald and Auschwitz, Dachau and Treblinka, Mauthausen and Majdanek, the author denounces the brutal appearance of fascism; he refutes the attempts of the international imperialist reaction to whitewash German fascism and rehabilitate the criminals generated by it.
