When Xia and I were in Beijing we went to a bookshop and it had an English section and I got a copy of a book called the Rape of Nanking, it was so enthrawling that I read it in about 4 days. When I say enthrawling it was also appalling what people can do to each other just for fun, like having beheading contests between officers and then putting the results in the papers back in Japan. When the war was over and they had some war trials for Japanese (another bug bear of mine and something the American Government has a little bit to answer for - but that is another issue) the two officers in question said they did not do anything, but when the newspapers were produced as evidence they were found guilty and hanged. Just desserts. But then again the Japanese have a lot to answer for during WW2 and until they can accept it and put it into their history maybe it will repeat.
I will get the name of the author and post it, I have lent the book to mum at the moment.
