I investigated reported Japanese atrocities committed by the Japanese Army in Nanking and elsewhere. Verbal accounts of reliable eyewitnesses and letters from individuals whose credibility is beyond question afford convincing proof that the Japanese Army behaved and is continuing to behave in a fashion reminiscent of Attila and his Huns. Not less than 300,000 Chinese civilians were slaughtered, many in cold blood.
