Vaivara
housed 1,300 prisoners at a time. These prisoners were mainly Jews, with smaller groups of Russians, Dutch, and Estonians.
The prisoners worked at various types of hard labor, including railroad construction, digging antitank ditches, quarrying, and cutting down trees in forests and swamps. They lived in wooden huts that let in the brutal cold, and they received meager food rations. In addition, water was scarce, while lice and illness were widespread. The prisoners were subjected to selections every two weeks, as a result of which many were murdered, while others died from SS beatings.
As the Soviet army drew closer, hundreds of the surviving prisoners were sent westward on death marches.
