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."
