Michael Dobbs - Saboteurs

As a concession to Kerling, Kappe agreed to get rid of Zuber and Scottie. But he insisted the others were “all right.” 40So it was decided. Two of the men would be dismissed. Nine would stay.

THE NAVY had agreed to transport the saboteurs to America by U-boat, but the question remained: how would they get from the submarine to shore? Kappe’s first idea was to equip them with collapsible rubber canoes, each of which had room for two men. The trainees practiced assembling and disassembling the boats, and took them out on the lake for practice landings. They quickly concluded it would be foolhardy to use the canoes on the ocean, particularly if the surf was high.

Kappe brushed aside their concerns. “They will be easier to navigate once they are fully loaded and are deeper in the water.” He pointed out that the canoes would also be transporting several boxes of sabotage equipment. 41The men were skeptical, but continued to practice with the canoes.

One day, while Dasch’s group was in the laboratory experimenting with explosives, screams were heard from the direction of the lake. An instructor rushed in with the news that one of the canoes had overturned. Everybody rushed down to the lake, where they saw Kerling and Haupt flailing about in the icy water. The lake had only begun to thaw a few weeks before, and the men were wearing heavy blue uniforms and boots that had been seized from the Polish army. Kerling had the presence of mind to pull his boots and pants off in the water; Haupt was practically drowning.

The instructors and some of the other men pushed a large rubber boat into the lake and mounted a rescue mission. Both men were dragged aboard, teeth chattering, faces blue-white. Back in the farmhouse, the hapless canoeists were rubbed down with alcohol, given some schnapps to drink, and sent to bed.

The next day, Kappe went to Berlin to report. That evening, he called Dasch by phone to announce that the navy had agreed to land the saboteurs in America in large rubber dinghies, to be manned by professional sailors.

THE LAST lesson at Quenz Lake was a two-hour course in secret writing. An instructor from Berlin taught the men some simple techniques, using a variety of everyday tools, such as laxative tablets, aspirin, and toothpicks. He began by demonstrating a method that relied on water, paper, and pencil. 42

First he soaked a piece of paper in a bowl of water. To prevent the paper from becoming wrinkled when he removed it from the bowl, he held it up by the top two corners, allowing the excess water to drain off. He laid the paper on a glass surface, and placed a dry sheet of paper on top of it. Using a black pencil, he then wrote a secret message on the top sheet of paper, pushing down hard enough so that an imprint was left on the wet sheet below. He removed the dry sheet, leaving the wet sheet on the glass until it had thoroughly dried. By this time, the writing had become invisible, and a camouflage letter could be written over it. The instructor showed the class how to get the secret message to magically reappear: simply immerse the now-dry paper in water again.

Other methods of secret writing left a jumbled impression with the men, particularly Dasch, who was confused by the whole business. “You buy a laxative,” he recalled later. 43“You use so many grains, add something, and you have the works. You use a toothpick and cotton and start writing, but you could never see it.”

The idea behind the training in secret writing was to give the men a secure way of communicating with one another in America, particularly if they were living in different cities. But when one of them asked the instructor whether the secret inks they had studied would withstand chemical analysis by the enemy, he replied bluntly, “No.” This set off a round of low muttering. 44

Most of the men concluded they were unlikely to have much use for secret writing.

FINAL EXAMS got under way at noon, on Wednesday, April 29. The instructors divided the men into pairs and handed out secret instructions on what to blow up. The targets—symbolizing a factory, an oil refinery, a railroad—were scattered around the estate. The Abwehr sent an additional fifteen observers from Berlin to assist the instructors and act as guards. The goal was to carry out the mission by noon the next day without being caught.

Dasch teamed up with Quirin, one of the men in his group. 45Unlike Dasch, Quirin was good with his hands, having worked as a machinist in the new Volkswagen plant in the town of Braunschweig in central Germany and, before that, as an odd-job man for rich Americans in Westchester County, New York. Together they were ordered to disable a make-believe manufacturing plant. They had twenty-four hours to prepare their materials, sneak into the factory, plant the bomb, and return safely to base. Since this was a trial run, they would use incendiaries rather than explosives such as TNT.

Dasch and Quirin returned to the laboratory to get everything ready. Together, they mixed the chemicals, just like Schulz had shown them. Then they prepared a detonator, fuse, and timing device. For the timer, Quirin chose a cheap pocket watch with a celluloid face. He opened up the watch and drilled a tiny hole in the side. He also removed the minute hand. He threaded some electrical wire through the hole, and attached one end to the hour hand and the other to a battery. He replaced the face of the watch, drilling another hole in the celluloid opposite the position for six o’clock. He inserted a small metal screw in the hole, also linked to the battery by electrical wire. When the hour hand came into contact with the screw, the circuit would be complete. By adjusting the hour hand, the saboteurs could now explode their bomb with a delay of up to eleven hours.

That night, when they thought the coast was clear, Dasch and Quirin crept up to the imaginary factory, an abandoned building at the edge of the estate. They reached the designated spot, and placed their bomb, hooking up the fuse and timer. But as they were leaving, instructors jumped out of the shadows, throwing firecrackers at them.

At least they had completed most of the assignment. Some of the others did not get that far. Heinck set off a loud explosion when he stepped on a booby trap as he approached his target. 46Another man was overcome by tear gas as he pried open the door of a small stone house, representing some kind of industrial plant. Throughout the night, the farm reverberated with the sound of firecrackers, explosives, and Molotov cocktails.

The most successful pair was Burger and Schmidt, alias Swensen. 47Their assignment was the destruction of a fictitious oil tank, located in a cellar of one of the buildings on the estate. First, they had to get into the cellar without being seen and find out the exact dimensions of the oil tank, which had been marked on the floor with chalk. After completing this part of the test, they returned to the laboratory to prepare the timing devices and explosives. Even though the cellar was guarded, they managed to sneak back inside a second time and set off their miniature bomb without being detected.

Kappe pronounced the exercise a success. Not everybody had done as well as Burger and Schmidt, but they had all been exposed to something approaching real-life conditions. Their nerves had been tested, and they had approached their tasks with enthusiasm. A lieutenant colonel who came from Berlin to observe the final exam was generous in his congratulations, remarking, “Never since the school started have I seen a bunch of men so eager.” 48

ON THE final day of class, Thursday, April 30, everyone gathered in the classroom to hear Kappe reveal their assignments in America. He produced a series of maps of the United States, with a detailed list of targets, along with graphs of American industrial production and photographs of bridges and railroads. 49
