One thing you may have overlooked in that article: "Civilian casualties also were heavy, amounting to thousands." (First sentence of "Civilian Casualties Heavy") Thousands? Wait, I thought this was a massacre of over 300,000 people? If this article is, indeed, 100% trustworthy, that alone would disprove the Chinese government's official stance of "300,000 killed."
I really don't think this article is very accurate, though, because the writer only relies on unverified witness accounts. For the record, there were only five Westerners in the area during the alleged time of the killings, and only 25 murder cases were officially reported by the Nanking Safety Zone Committee, none of them verified. Only two executions were witnessed personally by Westerners, and both were later found to be legal actions:
One, testified by Rev. John G. Magee, was of an incident on Dec. 17th, when two Japanese soldiers challenged a Chinese man on the street. The man ran away, and was shot. In the battlefield, such a case could not be avoided. The second one, witnessed by C. Kroeger and Hatz, of a plain-clothes man being executed near a pond, was investigated by the Safety Zone Committee, and found to be a legitimate execution.
Not that the Japanese don't keep track of everything either... If the rape of Nanking was indeed a massive military operation, why are there no documents about it in the Japanese army's archives? Wasn't it a military action?
Same goes for the Chinese. Why did the Chinese never bother to speak about this until after Japan surrendered?
Also, it wasn't Nazi Germany that was upset, it was John Rabe, the former German weapons trader in China, as well as chairman of the Nanking Safety Zone Committee. Of course he doesn't like the Japanese, because they requested that Germany stop selling arms to China, making Rabe go out of the arms business. Many of his accounts are known to be conflicting, as he sends differing numbers of casualties to different governments (to Japan, he said that 49 Chinese were murdered, to the British Embassy, hundreds, to the German Embassy, thousands, and finally to Hitler, 50,000 to 60,000). In the end, Nazi Germany disregarded Rabe's wild claims of the barbarity of the Japanese.
I don't want to sound like an infomercial, but...
I refer to "The alleged 'Nanking Massacre'" by Takemoto Tadao and Ohara Yasuo a lot, and I'd recommend it to anyone willing to hear the other side of the argument. We are, after all, a democratic country, are we not?
