Harbicht was wholly engrossed. He carefully considered the full ramifications of the general's statements. He was not surprised that Bormann, Himmler and Goering had at once thrown their support to the project. In the past they had all championed the cause of scientific research on behalf of the Reich. Their decrees had saved many a scientist from going to the front.
He felt a sudden chill of alarm. Why his presence now? Security, of course. But was there more? Had the Decker disappearance case come to the attention of Berlin? He still had no answers. And he vowed silently to double his efforts and to strengthen security still further in the Hechingen-Haigerloch area. But if nobody else brought the Decker case up now, he certainly would not.
He returned his attention to the general. The man's voice was getting on his nerves. It was thin and high-pitched, totally out of keeping with the importance of his rank.
The general brought out a small black notebook. He opened it.
“These are the questions I shall want answered,” he said crisply. “First. When do you plan to conduct the final test of the uranium machine? Cause the pile to go critical?”
Reichardt cleared his throat.
“Yes?” the general asked sharply.
“We — we did not reach infinite neutron increase today,” Reichardt explained, “because the size of our present pile is insufficient.” Again he cleared his throat. “Increasing the size by fifty percent and using exactly the same geometry, a self-sustaining chain reaction will definitely occur….”
“How will you accomplish this?”
“We must obtain an additional seven hundred and fifty kilograms of heavy water and a similar weight of uranium.”
“Are these supplies available?”
“Yes. At Stadtilm and elsewhere. It is a matter of logistics.”
“It will be arranged. At once. It is in accordance with the Führer Order of January Thirty-first.” He looked straight at Reichardt. “With these supplies brought here — when can you conduct your final test?”
Reichardt glanced around at his colleagues. They remained silent. He sighed.
“The nineteenth,” he said, “April the nineteenth.”
One of the other scientists spoke up.
It was Himmelmann. Harbicht mentally reviewed what he knew about the man: Himmelmann, Gustav, physicist. Like Decker? Born in Austria. Not a party member. Believed apolitical — totally involved in his scientific work….
The general waved a hand in dismissal.
“The Führer is aware of that. He has made plans for such contingencies. These plans will be revealed to you at the proper time.” He consulted his notebook. “Secondly. What is the power of a completed atomic bomb?”
Reichardt cleared his throat. “Exact calculations cannot be made at this time, General. We — we estimate one bomb will have the power of several thousand tons of high explosive.”
“So.” The general was obviously impressed, trying not to show it. “It would level an entire city?”
“It would.”
The general nodded with satisfaction. He made a note in his little book.
“There is, of course, also the possibility that once a chain reaction occurs — it cannot be controlled,” Himmelmann said, his voice soft.
The general looked startled “Meaning?”
Himmelmann shrugged.
The general turned to Reichardt. “Professor?”
