In Zollverein, in the spring of Werner’s tenth year, the two oldest boys at Children’s House—thirteen-year-old Hans Schilzer and fourteen-year-old Herribert Pomsel—shoulder secondhand knapsacks and goose-step into the woods. When they come back, they are members of the Hitler Youth. They carry slingshots, fashion spears, rehearse ambushes from behind snowbanks. They join a bristling gang of miners’ sons who sit in the market square, sleeves rolled up, shorts hiked to their hips. “Good evening,” they cry at passersby. “Or heil Hitler, if you prefer!”
