This is a riveting and disturbing account of the medical atrocities performed in Japan during WWII.In the first part of Unit 731: Testimony, author Hal Gold draws upon a painstakingly accumulated reservoir of sources to construct a portrait of the Imperial Japanese Army's most notorious medical unit, giving an overview of its history and detailing its most shocking activities. The second half of the book consists almost entirely of the words of former unit members themselves, taken from remarks they made at a traveling Unit 731 exhibition held around Japan in 1994-95.
