PROLOGUE
In the second week of January 1944, President Franklin Delano Roosevelt was personally informed by General William J. Donovan, the head of the OSS, of the existence of a pro-American German spy in the heart of the Reich. "We have secured through secret intelligence channels a series of what purport to be authentic reports, transmitted by various German diplomatic, consular, military, and intelligence sources to their headquarters. The source and material are being checked as to probable authenticity both here and in London. We shall submit later a considered opinion on this point. It is possible that contact with this source furnishes the first important penetration into a responsible German agency." General Donovan's memorandum was dated January 10, 1944.
"First important penetration" behind the scenes of the Nazi regime: The announcement was calculated to give the White House great satisfaction. Since the United States had entered the war against Germany and Japan in December 1941, Washington had been trying to make up for lost time in the field of intelligence. The British secret services were far in advance of their American colleagues, who had in no way foreseen the Japanese attack on Pearl Harbor on December 7, 1941, an event that had been a wake-up call hastening the establishment of the OSS a few months later.
General Donovan had been given a free hand to construct a worldwide intelligence network, but he had no spies in either Germany or Japan. Of course, a few Germans spoke to Americans when they traveled abroad, but this was sporadic. There was no secret agent in Berlin or Tokyo: the risks of capture were too great, the prospects for success too slender. The principal source of available intelligence on the Axis powers was the decoding of intercepted enemy telegraph or telephone communications. This procedure could not replace the quality of human intelligence, which was extraordinarily difficult to obtain.
The ideal spy had perhaps just been unearthed in Berlin: No one could be more useful than a well-informed German official, close to the center of power and decision making, and inclined to transmit his knowledge on a regular basis. For all of these reasons, his subordinates felt that the president of the United States should be personally informed of the existence of a German agent working at the German Foreign Ministry. In his January 10, 1944 memo, the head of the OSS informed Roosevelt that these documents would thenceforth be classified under the title of "Boston series"-a name that, like most used by the OSS, was probably chosen at random-and distributed to a very small number of people at the head of the government.
Attached to General Donovan's memorandum were fourteen very brief notes developed on the basis of elements supplied by the enigmatic spy, notes that contained a certain number of greatly significant facts. One German diplomatic dispatch dated October 6, 1943 explained that the head of the Gestapo in Italy, SS-Obersturmbannführer Herbert Kappler, had ordered the deportation of the Jewish community of Rome to the north with a view to "liquidating" it. A message from Ernst von Weizs?cker (ambassador to the Vatican since the spring of 1943), dated December 13, 1943, reported a conversation with Pope Pius XII, who expressed the wish that Germany "would hold out on the Russian front" and hoped that peace was near "or else communism would be the only winner." Still in Italy, Marshal Keitel (in the name of the führer) had given the order to execute without trial Italian officers who went over to the enemy (12 September 1943).
The most invaluable intelligence in Donovan's memo had to do with the Reich's communication channels. Berlin had installed a clandestine transmission post in Dublin. The German ambassador to Turkey, Franz von Papen, had a "mole" in the British embassy in Ankara. And most important, the Germans had an informer in the entourage of the vice president of the United States, Henry Wallace! Everything had to be done to plug the holes and prevent further leaks. The Germans might already be aware of the Allies' plan to land in France.
Roosevelt probably never learned the identity of the author of these revelations. Even the code name of the mysterious informer in Berlin, "George Wood," was kept secret. Only one or two people knew his real name and position: Fritz Kolbe, born in 1900, official in the central administration of the Foreign Ministry of the Reich in Berlin.
