Prisoners of War in Japan
The Japanese prison camps ignored the terms of the Geneva Convention and the Allied captives were treated horribly.
"The stench of this hut was beyond description. Dysentery patients were fouling their bed spaces, unable to hold on until the arrival of the bamboo bed pans; tropical ulcers, some running from the knee to ankle, with maggots wriggling in the suppuration, stinking to high heaven. As well, the open trench latrine was about ten metres away overflowing with the help of monsoon torrents and spreading the filth around an area of some twenty or more square metres."
