The Nazi regime, headed by Adolf Hitler, sought to punish its enemies, as well as to exterminate Jews, Gypsies, and other groups deemed inferior, by starving, shooting, and gassing them in a vast network of concentration camps. Most lethal of all were six death camps built in Poland, the largest being the infamous Auschwitz. Filled with eyewitness testimony, this volume tells the story of the shocking war crimes enacted in those camps and how those awful places were eventually liberated.
