actually i didnt know indian troops fought against us in Europe. I just know people who fought Indian troops in Asia. For example when we fought to get the philippines back.
They were militarily useless propaganda troops. I read about an argument where Hitler sneeringly asked why the Frei Hind were always "refitting" without ever having fought.
But what the article demonstrated, as was clear, was that the British Army of India was no longer politically reliable by 1946. India did not have a large, politically powerful white settler population so once the army turned India was lost.
