@ 1978 there was a BBC series that impressed me deeply called Plains Tales of the Raj-based upon the book. I grew up with a lot of old India army officers as my neighbors and my Housemaster at school was one of the last Subltons commissioned in India. He served out his time later in Borneo, Malaya and Hong Kong with the Ghurkas and ate Japanese POW given to him by Borneo tribesmen. They were pukka men-if they gave their word, they kept their promise. They all had mustaches, were horse mad and drank whiskey or Pims in the afternoons.
In the BBC series one of the last men they interviewed was a 90-something retired Subalton who had served on the Afghan Frontier in his teens. Leading a patrol up a hill a tribesman popped up and took a shot at him-wounded him and then went in with his knife to finish the teenaged Lt. off. The young chaps' batman and the tribesman wrestled over the knife and eventually the Lt. shot the tribesman with his revolver, but only after the batman got fatally stabbed. As he lay dying he said, "But Sir, what will become of my family?" and the Lt. said, "Do not worry; I shall ensure they are alright. I give my word of honour" ...and -as the batmans' eyes glazed over- he said, "then it is alright, because I have the word of a British officer"....
The old man-wearing a white sari as i recall-and with annoyed younger Indian women in saris hovering in the background- stayed on taking care of the batmans' family financially. "I never went home because I had promised you see"...said the 90 year old.
Only the British officer class....
