For those of our readers who have been with us through the journey so far, we have covered a lot of distance. From the Anhalter Banhof station in Berlin we went to the bylanes of Calcutta, which we saw through the eyes of Rudyard Kipling. At the Brigade Parade ground, we heard ‘The Internationale’. We found why Scottish soldiers were forbidden by their superiors from playing, singing and even whistling native tunes – because that triggered their nostalgia, which, in its early days, was identified with lethargy, confusions between past and present, real and imaginary events, and ghost sightings. We hopped on to the public transport of New Delhi and ruminated about the Naxalbari insurgent movement. In this penultimate instalment, we will explore Berlin's past and meet an American soldier who defected to the Eastern Bloc during the early years of the cold war.
