I saw a documentary last night about the war in Burma.
British troops found a scene where their wounded and the medical orderlies were massacred by Japanese, being horribly mutilated. After, Japanese were seldom taken alive.
Brigadier John Masters, DSO, etc. moved to the USA after the war and became a famous author. His basic regiment was the 4th Gurkha Rifles.
He wrote in his autobiography that after seeing various Jap atrocities, he had no more regard for them than if he was stepping on roaches.
He cited the case of a young Lt. who reported his casualties to HQ in India. He mentioned some men "Captured, presumed killed."
Told by a superior officer that there was no such category, he replied, "Sir, we are fighting the Japanese."
If I remember right, and if we are both referring to the same incident, the Japanese removed body parts and consumed them, even with adequate supplies.
Another incident:
"But the most spine-chilling of all Japanese atrocities was cannibalism.
"At the village of Suaid, a Japanese medical officer periodically visited the Indian compound and selected each time the healthiest men. These men were taken away ostensibly for carrying out duties, but they never reappeared," the Melbourne correspondent of The Times, London, cabled the version of Jemadar Latif of 4/9 Jat Regiment of the Indian Army, on November 5, 1946.
Latif's charges were reinforced by Captain R U Pirzai and Subedar Dr Gurcharan Singh. "Of 300 men who went to Wewak with me, only 50 got out. Nineteen were eaten. A Jap doctor —Lieutenant Tumisa, formed a party of three or four men and would send an Indian outside the camp for something. The Japs immediately would kill him and eat the flesh from his body. The liver, muscles from the buttocks, thighs, legs, and arms would be cut off and cooked," Captain Pirzai told Australian daily The Courier-Mail in a report dated August 25, 1945.
Many other testimonials of the PoWs gave details of the cannibalism practised. These were used by the war crimes investigation commissions set up by the Allies, based on which several Japanese officers and men were tried.
The senior-most Japanese officer found guilty of cannibalism and hanged was Lieutenant General Yoshio Tachibana.
Initially, the Japanese did not accept the charges. Then in 1992, a Japanese historian named Toshiyuki Tanaka found incontrovertible evidence of Japanese atrocities, including cannibalism. In 1997, Tanaka came out with his book, Hidden Horrors: Japanese War Crimes In World War II."
Do a google search of Japanese atrocities and you'll find more (with documentation). I had a scoutmaster who survived the Bataan Death March and he would never talk about it!
