I can't remember the title but there was a short story by Turtledove that
@Thande showed me if I remember correctly.
The premise was that Britain had fallen to the Nazis but a Fighting Britain had battled on beyond the seas. To no avail. The Teutonic war machine had crushed the Soviet Union and finally come marching over the Khyber Pass and captured the jewel of the old Empire's crown. And it was basically how does the Indian independence movement, revolving around Gandhi and the principle of nonviolent civil disobedience, deal with the British colonial government being replaced by a Nazi Reichskommissariat.
