Located 62 miles south of Zagreb, Croatia, Jasenovac was Croatia's largest concentration (sabirni logor) and extermination camp. Jasenovac was a network of several sub-camps, established in August, 1941 and operative until April, 1945. The Germans gave control of Jasenovac to the Croatian people, which was run by the fascist, antisemitic, and terrorist Ustasa movement. A large number of Ustasa members served in the camp, most notably Miroslav Filipovic-Majstorovic, who was notorious for killing prisoners with his bare hands. The National Committee of Croatia for the investigation of the crimes of the occupation forces and their collaborators stated in its report of November 15, 1945 that 500,000-600,000 people were killed at Jasenovac. Conditions in the Jasenovac camps were horrific. Prisoners were starved and shelter and sanitary facilities were non-existent. The guards cruelly tortured, terrorized, and murdered prisoners at will.
