The Nazi regime found it hard to admit that the largest formation in the whole of the Wehrmacht was doomed to annihilation in the ruins of Stalingrad and in the frozen steppe outside. To prepare the country for bad news, Joseph Goebbels, the Reichsminister for Propaganda and Enlightenment, had announced a ‘German Christmas’, which in National Socialist terms meant austerity and ideological determination, not candles and pine wreathes and singing ‘Stille Nacht, Heilige Nacht’. By 1944, the traditional roast goose had become a distant memory.

In streets where the façade of a house had collapsed, pictures could still be seen hanging on the walls of what had been a sitting room or bedroom. The actress Hildegard Knef gazed at a piano left exposed on the remnants of a floor. Nobody could get to it, and she wondered how long it would be before it tumbled down to join the rubble below. Messages from families were scrawled on gutted buildings to tell a son returning from the front that they were all right and staying elsewhere. Nazi Party notices warned, ‘Looters will be punished with death!’

Air raids were so frequent, with the British by night and the Americans by day, that Berliners felt that they spent more time in cellars and air-raid shelters than in their own beds. The lack of sleep contributed to the strange mixture of suppressed hysteria and fatalism. Far fewer people seemed to worry about being denounced to the Gestapo for defeatism, as the rash of jokes indicated. The ubiquitous initials LSR for Luftschutzraum, or air-raid shelter, were said to stand for ‘Lernt schnell Russisc’: ‘Learn Russian quickly’. Most Berliners had entirely dropped the ‘Heil Hitler!’ greeting. When Lothar Loewe, a Hitler Youth who had been away from the city, used it on entering a shop, everyone turned and stared at him. It was the last time he uttered the words when not on duty. Loewe found that the most common greeting had become ‘Bleib übrig!’ — ‘Survive!’
