47He dated a young: Bergens Tidende, February 1, 2015.

At the start of: Skinnarland Notes, ESP. In many histories of the Vemork action, Skinnarland is described as having in hand intelligence on the heavy water activities of the Germans at Vemork at the time he traveled to Britain. This is clearly not the case, as stated by Einar Skinnarland himself. He left for England with the intention of starting a wireless-transmission site to provide intelligence on German activity in the area, no doubt centering on Norsk Hydro.

The son of a ship’s: “Cheese’s Report,” July 30, 1941, TNA: HS 2/150; John Wilson, “On Resistance in Norway,” NHM: Box 50A.

Now that he: “Clairvoyant,” January 1, 1942, TNA: HS 2/218.

A team was: Rjukan, December 20, 1941, TNA: HS 2/184. There was also a draft of a plan for six men to blow up the pipelines and valves above the plant, but this was clearly nixed in favor of the bombing run, as confirmed by the recollections of Poulsson (Poulsson, 75).

53Before Skinnarland’s arrival: Operation Grouse, March 28, 1942, NHM: SOE, Box 22.

Skinnarland could prepare: Ibid. In the original operational instructions, there was no mention of Skinnarland providing intelligence on heavy water.

58“and we’re working”: Powers, 124. The famous Heisenberg-Bohr meeting is one of enduring attraction for historians and dramatists alike. What was said, who said it, what they meant​ — ​these remain open questions. The author will leave it to such fine books as Thomas Powers’s Heisenberg’s War to parse the truth, but as Powers suggests, the British very likely learned of this conversation by spring 1942.

As early as: Gowing, 43.

After the occupation: Jablonski, 93–95.

Thanks to the Nazis’: Irving, 72; Walker, German National Socialism, 26–27. There has been much written about the erroneous calculations of Walther Bothe on graphite as a moderator, namely that Bothe’s findings contributed to the Germans’ concentrating solely on heavy water. Making a well-sourced, thorough explanation of why the German program would have pursued heavy water regardless of Bothe’s work, Mark Walker writes that Heisenberg figured a reactor using graphite required “much more uranium and much more moderator than a heavy water device” and that Army Ordnance determined that “boron and cadmium-free carbon of sufficient purity could be produced, but only at prohibitive costs.”

The many original sources given here reflect an enduring controversy among members of the sabotage operation as to who suggested what in terms of the overall planning. However, one thing is clear: Tronstad suggested the approach across the gorge as offering the team the best chance of success.

181“Is that edible?”: Haukelid, 95–96.

On Thursday, February 25: Sørlie Memoir; Finn Sørlie, Author Interview.

“I’m glad it’s”: Sørlie Memoir.

Interest in the: Karlsch, 45–53, 126; Nagel, 42–44; Irving, 77, 125–26, 153–55; Walker, German National Socialism, 88. There has been much written about the June 4, 1942 meeting with Speer sounding the death knell to the Nazi atomic program. If the meeting had gone the other way, it might have prompted an immediate Manhattan Project–like intensity to the program, vastly improving the odds of a German bomb. That said, after June 1942, the project still held a high DE rating (Dringlichkeitsentwicklung), the highest priority rating for material/manpower, and there were a plethora of powerful patrons at the ready if progress could be shown.

It should be noted that in most historical accounts General Rediess and Terboven were stated to have come to Rjukan on February 28, 1943, just hours after the sabotage. The report by Nilssen never states their presence, and his account is exhaustive.

Early the next: Falkenhorst Note, February 28, 1943, RW 39/43, Barch-MA.

In his diary, Skinnarland mentions Gunnerside on March 5, but in a cryptic way (that is also likely a typo): “Operasjonen Gunnerside iorden.” Potentially, “Operation Gunnerside in order.” As his daughter Marielle Skinnarland corresponded with the author, this entry intimates that Skinnarland found out about the sabotage from local farmers in Lie. However, against the clear account from Haukelid in his memoir that the news he shared with Skinnarland about the sabotage came indeed as news, the author followed the Haukelid version.

Approaching Skårbu: Haukelid, 120–21.

“Don’t worry, Knut”: Ibid., 121.

218Haugland tried to: March 6–11, 1943, ESD; Interview with Haugland, IWM: 26624. It is clear from Skinnarland’s diary that he received the news on this date; however, the first message to London was not sent until the tenth. On this date and the next, Skinnarland makes short mention of issues with connection and the radio’s oscillator.

“You can bet”: Haukelid, 122.

At noon on: Rønneberg Report.

Rønneberg had always: Rønneberg Interview, Moland; Myklebust, 166–69; Mears, 180–81.

219The next day: Rønneberg Report.

20. THE HUNT

220In Møllergata 19: Skogen, 96–105; Report by Gunlsik Skogen, December 1, 1943, TNA: HS 2/174.

223All the while: Precis of a Meeting between Professor Goldschmidt, Professor Tron-stad, and Lt. Commander Welsh, March 15, 1943, LTP.

The Danish physicist: Letter from Eric Welsh to Tronstad, January 16, 1943, LTP.

“heartbeats”: March 18, 1943, LTD.

On March 13: Rønneberg Report; Rønneberg Interview, Moland; Myklebust, 173–88. The march to Sweden was one of the most remarkable aspects of the Gunnerside operation. Rønneberg recounts it in detail in his report, but a better, longer chronicle comes from Gunnar Myklebust in his biography of the saboteur. These are the three primary sources for the description of this retreat given here.

224“You must all”: Rostøl and Amdal, 97–99.

Under the light: Rønneberg Report; Mears, 182–85. On the survival skills of the saboteurs, Mears offers fine insight.

225“All right, let’s”: Rønneberg Interview, Moland.

“Guys”: Myklebust, 182–83.

As night fell: Interview with Rønneberg, IWM: 27187; Rønneberg Interview, Moland; Rønneberg Report.

“When this war”: Haukelid, 129–30.

Over two weeks had: Ibid., 124–31.

227“It’s not safe”: Berg, 137.

Kjelstrup left: Report by Arne Kjelstrup, October 30, 1943, NHM: SOE, Box 23.

After reports pointed: Report “Angår Aksjonen på Hardangervidda,” July 17, 1946, NHM: Box 10B; Report on the Interrogation of Major Ernst Lutter, July 5, 1945, NHM: Box 16; Tätigkeitsbericht AOK/Ic, April 1943, RW 39/44, Barch-MA; Ueland, 191–93; Helge Dahl, Rjukan, 291. Figures on those involved in the March–April 1943 razzia range everywhere from two thousand to twelve thousand men. The key confusion likely rests around the fact that there were three actions conducted at roughly the same time, as outlined by Major Lutter, who participated in them. Exact numbers have yet to be uncovered, but Lutter states three thousand men in the Hardangervidda, another with an “even more formidable army” for regions south and west of the Vidda, and the third with two thousand men in northern Norway near Trondheim.

228A Norwegian hunter: Haugland Report; Lunde, 109.

“Seven men were”: Report, “Vemork kraftstasjon,” March 24, 1943, NHM: FOIV, Box D17.

The narrative of Helberg’s dramatic escape between March 25–30 derives primarily from these four sources. The author has also consulted Gallagher, 149–63; Interview with Claus Helberg, KA; Ueland, 194–201, 212–16. Any quotes or other select material will be separated out in the endnotes.

233“Halt! Arms up”: Interview with Helberg, IWM: 26623.

234“You have to”: Ibid.

The boat for: There remains some discrepancy in the sources about what hotel Helberg stayed in during his time in Dalen. Some refer to the Bandak Tourist Hotel, others to the Dalen Hotel. Given the Dalen Hotel was the nicest hotel in the town as well as the fact that the Germans set up headquarters there, the author sided with Dalen.

235The conversation was: Letter from Wehrmachtsbefehlshaber in Norwegen, May 15, 1943, RW 4/639, Barch-MA.

W. Street, December 22, 1943, TNA: AIR 2/8002.

“We get nothing”: Letter from Tronstad to Bassa, December 8, 1943, LTP.

“It is hard”: April 30, 1943, LTD. This reflection matches perfectly the one expressed by Malcolm Munthe, his British colleague, who on May 3, 1943, sent Tronstad a letter that stated, “As you perhaps have known​ — ​I have for some time past felt​ — ​very keenly, when sending out into the field some of my Norwegian friends​ — ​the need to once again try to do my bit in the active side of the war myself.” Letter from Munthe to Tronstad, May 3, 1943, DORA: Correspondence 1937–45.

At the same: Mark Walker and Rainer Karlsch, “New Light on Hitler’s Bomb” (Physics World, June 1, 2005); Nagel, 92–93; Irving, 213–17. There is little doubt Diebner was working on this effort. The bigger controversy revolves around its suc-cess or failure. Irving skirts away from the answer, but Karlsch argues in his book that Diebner and crew successfully tested such weapons. Whether they did​ — ​or did not​ — ​the author agrees with the Karlsch/Walker article that says: “What is important is the revelation that a small group of scientists working in the last desperate months of the war were trying to do this.”

27. THE MAN WITH THE VIOLIN

291The following day: Interview with Alf Larsen, DIA: DJ 31; Interview with Knut Haukelid, DIA: DJ 31.

“I know it’s”: Drummond, 160.

It was one: Haukelid, 187.

Haukelid continued: Haukelid, Report on the Sinking of the Ferry Hydro, February 20, 1944, NHM: SOE, Box 23.

292“place a time”: Ibid.

Next they needed: Kjell Nielsen, “Notat angående omtalen av fergeaksjonen på Rjukan i Februar 1944,” NHM: Box 10B; Interrogation of Gunnar Syverstad, April 5, 1944; Account given by Engineer Larsen of the transaction during the attack on Tinnsjø Ferry, February 20, 1944, NHM: SOE, Box 23; Sørlie Memoir.

The pensioner had: Diseth, Friends Report, NHM: SOE, Box 23B; Haukelid, Report on the Sinking of the Ferry Hydro, February 20, 1944, NHM: SOE, Box 23; Gallagher, 175–76.

293The next day: Interview with Haukelid, DIA: DJ 31.

The ferry: Payton and Lepperød; Interrogation of Gunnar Syverstad, April 5, 1944, TNA: HS 2/188; Irving, 203.

When Haukelid boarded: Haukelid, Report on the Sinking of the Ferry Hydro, Feb-ruary 20, 1944, NHM: SOE, Box 23; Haukelid, 187–88; Interview with Haukelid, DIA: DJ 31; Interview with Haukelid, IWM: Oral History.

294It turned out: Interview with Knut Lier-Hansen, KA; Report by Gunlsik Skogen, December 1, 1943, TNA: HS 2/174; Knut Lier-Hansen, Friends Report, NHM: SOE, Box 23B.

295Haukelid liked Lier-Hansen: Haukelid, 189. There is some murkiness in regard to when Lier-Hansen joined the team. In his own interview, Lier-Hansen puts himself fairly center stage as early as February 10, but this runs against most other accounts, which do not have him coming aboard until the final days (and relate the worry of still being a man down). Sørlie and Haukelid both recount this version. Given the assembly of evidence, February 18 looks to be the most likely scenario. Haukelid states explicitly they met this day in his after-action report and Lier-Hansen is not mentioned in any of the meetings that Larsen, Syverstad, or Nielsen participated in prior to that date.

“smashing”: Larsen, 1242–49.

306Of the fifty-three: Haukelid, 197; Omkomne D/F Hydro, February 20, 1944, VM: IA4FB, Box 13. The exact numbers on the ferry that day are somewhat obscured by the fact that the ticket clerk​ — ​and his records​ — ​were lost in the sinking. The final accounting comes from an intelligence report found by Knut Haukelid after the war in the records of the military governor of Norway.
