U.S. intelligence had been able to confirm Respondek’s tips, for they had broken Japanese codes in September 1940 and, after Major General Hiroshi Ōshima, Japan’s onetime ambassador to Berlin, had been returned to the Nazi capital, thanks to Matsuoka, the Americans gleaned a mother lode of intelligence: the staunchly pro-German Ōshima, who spoke the language nearly perfectly, was taken into the confidences of Ribbentrop and Hitler. (Ōshima had been able, in February, to present his credentials at the Berghof.) In April 1941, U.S. cryptographers finished decoding long messages sent from Matsuoka’s late-March visit with Hitler. “Göring was outlining to Ōshima Germany’s plans to attack Russia . . . , giving the number of planes and numbers and types of divisions to be used for this drive and that,” recalled one of the cryptographers. “I was too excited for sleep that night.” The United States passed additional warnings to Umansky. But he would tell the press that “information presented to the Soviet Union in London and Washington is aimed at provoking a conflict between Germany and the USSR.”163
ATTEMPTED DETERRENCE
Dekanozov, from Berlin, sent the foreign ministry a special report in April 1941 noting that rumors and information about a pending war between the USSR and Germany “are coming to us every day from various channels” and calling the pressure a deliberate “war of nerves.” Listing a dozen or so examples, he stated that the goal of Germany was “an attack on the USSR already during the course of the current war against England.”164 On April 15, in the area of Rovno, in western Ukraine, after one German reconnaissance plane performed a forced landing, the crew was found to possess “a camera, some rolls of used film, and a torn topographical map . . . of the USSR, all of which gives evidence of the crew’s aim.” The NKGB detained four officers in leather coats lacking insignias; supposedly, they had been unable to destroy their film in time. Once developed, it showed bridges and rail lines along the Kiev axis, while the map turned out to be of Ukraine’s Chernigov province. It was as if the Germans
On April 21, the Soviet foreign affairs commissariat protested German violations of its airspace—some eighty incidents over the preceding three weeks alone. The German chargé d’affaires, Werner von Tippelskirch, who received the diplomatic note, warned Berlin “to expect likely serious incidents if German airplanes continue to violate Soviet borders.”166 He was dead wrong. Stalin had begun to unblock shipments to Germany in mid-April—Soviet oil deliveries doubled from the previous month—signaling that the Germans could get what they needed without war (or, conversely, that if Hitler attacked, he would lose the valued goods the Soviets were supplying).167 Stalin also abruptly ended Soviet objections to the German position demanding small changes to their common border.168 To be sure, the despot understood that too many concessions would be perceived as weakness. And so, by not interdicting German overflights, he was effectively allowing the Germans to see what they would face.169
“We must hope for the best and prepare for the worst,” Chamberlain had said of appeasement, which would have been a good idea, especially if he had done what he said and pursued both rearmament and diplomacy, but the former remained very partial.170 Stalin pursued rearmament vigorously. As a result, the Soviet people stood in queues for hours upon hours to obtain necessities, and often they could still not meet their minimum needs.171 Germany had shown the Soviets their military production facilities, where the Soviets shopped as part of their bilateral trade agreement. Stalin, under no obligation to reciprocate, since the Germans were buying raw materials, nonetheless showed them Soviet military factories. He allowed a tour of the chief aviation factories, including the one building the Petlyakov Pe-8 bombers, which caused a sensation: it had a longer range than the German Junkers.172 In April 1941, during a visit to one such factory, the aircraft designer Artyom Mikoyan told Schulenburg—who, as expected, passed the words on to Berlin that same month—“You saw the awesome technology of the Soviet country. We will bravely repel any strike no matter where it might emanate from.”173
