By now you know all about the heroic (?) deeds of the INA in East Asia. But you would not know about the Indians who fought in Hitler’s SS. The SS was not really racist-it had units from much of the Commonwealth, even a British unit as well as numerous non-Aryans from all over.
The main reference is:
though I am summarizing the main points below:
India: 2,500 in the
Indisches Freiwilligen Infanterie Regiment 950 or “Tiger Legion” This is described in some detail (including Netaji’s role) here: https://en.wikipedia.org/wiki/Indian_Legion
Stranger still was the story of the Britischer Freikorps in the SS (which had a peak strength of 27, not enough for a platoon).
This was indeed so obscure that few people in Britain had heard about it until the publication of the popular novel “The Eagle Has Landed” in the mid-70s. But it does not seem to figure in the movie.
The British government did, indeed, execute a few individuals such as William Joyce (Lord Haw-Haw) and John Amery for participating in broadcasts for Germany’s Ministry of Propaganda (headed by Herr Goebbels). But the irrelevance of the British Free Corps meant that nothing much happened to them.
