Jasenovac concentration camp
Ustasas Hinko Dominik Picilli and Tihomir Kordić controlled the labor section.  Picilli would personally whip inmates to make them work harder.  He divided the "Jasenovac labor force" into 16 groups, including groups of construction workers, brick-workers, metal-works, and agricultural workers.  Many inmates died from the hard work.  Brick-working was especially hard and dangerous.  Inmates working as blacksmiths were forced to make knives and other weapons for the Ustaše.  Building dikes was the most feared job of all.
