I would highly suggest reading [Prisoners of The Japanese: POWs of World War II in the Pacific] (https://www.goodreads.com/book/show/573136.Prisoners_of_The_Japanese) by Gavan Daws.

This book compiled hundreds of interviews from surviving POWs in Japan during World War II. Seeing as one in four died in the hands of their captors due to disease, torture, or execution, there is plenty of content to analyze and take note of.
