That the Deputy Führer had been captured in Britain was something that shook the regime to its foundations. As Goebbels sarcastically pointed out, it never appears to have occurred to Heß that this could be the outcome of his ‘mission’. It is hard to imagine that it would not have crossed Hitler’s mind, had he been engaged in a plot. But it would have been entirely out of character for Hitler to have involved himself in such a hare-brained scheme. His own acute sensitivity towards any potential threat to his own prestige, towards being made to look foolish in the eyes of his people and the outside world, would itself have been sufficient to have ruled out the notion of sending Heß on a one-man peace-mission to Britain. But, in any case, there was every reason, from his own point of view,
Certainly, Hitler was a gambler. But he invariably weighed the odds and took what seemed to him calculable risks. He was always highly nervous, even hesitant, before any attempted coup. In this instance, his behaviour was unremarkable in the days building up to the Heß drama. The chances of the Heß flight succeeding — even if, for which there is no evidence, there had been enticement from the British Secret Service — were so remote that Hitler would not conceivably have entertained the prospect.216 And had he done so, it is hard to believe that he would have settled on Heß as his emissary. Heß had not been party to the planning of ‘Barbarossa’. He had been little in Hitler’s presence over the previous months. His competence was confined strictly to Party matters. He had no experience in foreign affairs. And he had never been entrusted previously with any delicate diplomatic negotiations.217
In any case, Hitler’s motive for contemplating a secret mission such as Heß attempted to carry out would be difficult to grasp. For months Hitler had been single-mindedly preparing to attack and destroy the Soviet Union precisely in order to force Britain out of the war. He and his generals were confident that the Soviet Union would be comprehensively defeated by the autumn. The timetable for the attack left no room for manoeuvre. The last thing Hitler wanted was any hold-up through diplomatic complications arising from the intercession by Heß a few weeks before the invasion was to be launched. Had ‘Barbarossa’ not taken place before the end of June, it would have had to be postponed to the following year. For Hitler, this would have been unthinkable. He was well aware that there were those in the British establishment who would still prefer to sue for peace. He expected them to do so
Rudolf Heß at no time, whether during his interrogations after landing in Scotland, in discussions with his fellow-captives while awaiting trial in Nuremberg, or during his long internment in Spandau, implicated Hitler. His story never wavered from the one he gave to Ivone Kirkpatrick at his first interrogation on 13 May 1941. ‘He had come here,’ so Kirkpatrick summed up in his report, ‘without the knowledge of Hitler in order to convince responsible persons that since England could not win the war, the wisest course was to make peace now. From a long and intimate knowledge of the Führer, which had begun eighteen years ago in the fortress of Landsberg, he could give his word of honour that the Führer had never entertained any designs against the British Empire. Nor had he ever aspired to world domination. He believed that Germany’s sphere of interest was in Europe and that any dissipation of Germany’s strength beyond Europe’s frontiers would be a weakness and would carry with it the seeds of Germany’s destruction.’ He admitted, when pressed by Kirkpatrick on whether Russia was to be seen as part of Europe or Asia, that Germany had some demands on Russia, but denied that Hitler was planning to attack the Soviet Union.218
