I’ve been looking at those trains passing through Hungary, carrying refugees from further east, and seeing the Hungarian police offer them food and water, which they throw on the ground in contempt. And I’m reminded of other trains travelling the same route, 72 years ago, also en route to a place that in those days was in Germany. Those passengers, when the train stopped at a station, offered gold and jewellery for the privilege of a mug of water. But this was denied them. They arrived in a Germany, all right, but there were no lines of happy faces carrying placards saying ‘Welcome’. Just soldiers, dogs and whips. And a chimney.
