My being sent to Königsberg in 1944 was supposed to be a punishment and feel like an exile from Berlin, but to me it felt like I was almost going home, especially as, until that summer, the city and most of East Prussia had been largely untouched by the war. As things turned out it was perhaps fortunate I was away from Berlin and out of anyone’s mind when Count von Stauffenberg made his failed attempt at a coup in July 1944, otherwise I might have been swept up in the wave of executions that followed. More than a hundred kilometers to the southeast of Königsberg, Hitler came on German radio and announced he was alive, and if anyone was there to witness a demonstration of loyalty and affection—but only if they were—people breathed a great sigh of relief.

I was a lowly lieutenant, an officer attached to the 132nd Infantry Division and the FHO—the branch of German military intelligence responsible for the Eastern Front—and it was my job to help make meaningful assessments of Soviet capabilities and intentions, and communicate these with the army commanders on Paradeplatz. Those assessments were very simple: The Red Army was poised to annihilate us.

As an officer I was entitled to a room at the Park Hotel, on Huntertragheim Street and close to the Lower Pond. Built in 1929, the Park was the last word in modern luxury; at least it was until almost two hundred RAF Lancaster bombers turned up on two consecutive nights at the end of August 1944 and bombed the city to bits. Almost every building to the south of Adolf-Hitler-Platz, including the famous castle and the cathedral where Kant was buried, were destroyed or damaged. Thirty-five hundred people were killed and tens of thousands made homeless—a foretaste of the terrible fate that was soon to befall Berlin. The upper floors of the Park Hotel and many of the men living on them disappeared in fire and smoke, but the second floor I lived on was spared and somehow the restaurant next door survived, too, which was just as well as it was one of the few places where German officers were allowed to take girls from the women’s auxiliary services who, even in 1944, were sometimes strictly chaperoned.
