Edit: some more info. 881 Aleuts were gathered up, endured slave labor, and 118 died from lack of food, warmth or medical care. All extremely preventable as is evidenced by the camp just 30 miles away of around 700 Nazi POWs. All 700 returned home alive and in good health. Historian Stan Cohen even wrote, "All in all, the German imprisonment in Alaska was quite pleasant."
