In December of 1937, the Japanese Imperial Army marched into China's capital city of Nanking and began to murder 300,000 out of 600,000 civilians and soldiers in the city. The six weeks of carnage would become known as the Rape of Nanking and represented the single worst atrocity during the World War II era in either the European or Pacific theaters of war.The actual military invasion of Nanking was preceded by a tough battle at Shanghai that began in the summer of 1937.

Unlike the troops at Shanghai, Chinese soldiers at Nanking were poorly led and loosely organized. Although they greatly outnumbered the Japanese and had plenty of ammunition, they withered under the ferocity of the Japanese attack, then engaged in a chaotic retreat.

So they looked at Chinese POWs with utter contempt, viewing them as less than human, unworthy of life.The elimination of the Chinese POWs began after they were transported by trucks to remote locations on the outskirts of Nanking.
