1. Anthony Read and David Fisher, Operation Lucy: Most Secret Spy Ring of the Second World War (New York 1981), 163.
2. The best monograph on the Red Orchestra (including Lucy) is The Rote Kapelle: The CIA's History of Soviet Intelligence and Espionage Networks in Western Europe, 1936-1945 (Frederick, Md. 1979), prepared by the Central Intelligence Agency ca. 1973 (hereafter cited as Rote Kapelle): on Lucy, see 165ff.
3. For a critical review of the literature and various theories regarding Lucy, see Nigel West, A Thread of Deceit: Espionage Myths of World War II (New York 1985), 51-67. The chief memoirs include: Alexander Foote, Handbook for Spies (Garden City, N.Y. 1949); Alexander Rado, Codename Dora, trans. by J.A. Underwood (London 1977); and W.F. Flicke, Agenten Funken Nach Moskau: Funkspionagegruppe'Rote Drei' (Wels-Munich 1957). Journalistic accounts include Pierre Accoce and Pierre Quet, A Man Called Lucy, trans. by A.M. Sheridan Smith (New York 1968), and Read and Fisher, Operation Lucy.
4. The controversies and claims to 1970 are reviewed in Heinz Hoehne, Kennwort: Direktor (Frankfurt/M. 1970), 13-25, an excellent study of the Soviet espionage network in Germany in 1942. Paul Carrell's narrative history of the Eastern Front at this time, Scorched Earth: The Russian-German War 1943-1944, trans. by Ewald Osers (Boston 1970), devotes an entire chapter to the betrayal of information prior to Kursk (pp. 95-114). Reinhard Gehlen, wartime director of the German Army High Command's intelligence section for the East, Fremde Heere Ost, alleged in his memoirs that he had obtained 'proof' that the traitor was Martin Bormann (see The Service: The Memoirs of General Reinhard Gehlen, trans. by David Irving [New York 1972], 70-1). See also Wilhelm von Schramm, Verrat im Zweiten Weltkrieg: Vom Kampf der Geheimdienste in Europa, Berichte und Dokumentation (Duesseldorf/Vienna 1967).
5. Rote Kapelle, 173, 185. Of these, 332 are messages from Dora to 'Director' (Moscow), the remainder transmissions of instructions from Moscow. According to Hoehne (Kennwort, 63-4), the Director was Gen. Ivan T. Peresypkin, head of the 'Razvedupr' (short for 'Glavnoe Razvedyvatelnoe Upravlenie', or Chief Intelligence Administration of the Soviet General Staff, alternately known as the GRU or the 'Fourth Department').
6. Attempts to locate the collection of intercepts cited by the CIA proved fruitless. Joseph Thach, Jr., in his solid monograph, 'The Battle of Kursk July 1943: Decisive Turning Point on the Eastern Front' (unpublished PhD dissertation, Georgetown University, 1971 ), 214-5, 534, quotes from a collection of these messages in the custody of David Dallin's widow in New York, to which Thach apparently gained access. The best published collection of these intercepts appears in Schramm, Verrat, 350-64.

12. The initial determination to defend the Kursk salient and prepare for a summer offensive resulted from a series of meetings between Stalin and his senior generals between 8 and 12 April 1943: see Georgi K. Zhukov, The Memoirs of Marshal Zhukov, trans. by Novosti Press Agency (New York 1971), 427-39, and G.A. Koltunov and B.G. Solovyov, Kurskaya Bitva (Moscow 1970), 27-35. See also footnote 17 below.

14. 'Dora an Direktor (von Rot)', 20 April 1943, in Flicke, Agenten, 329, and Rote Kapelle, 191.
15. The key extracts of these messages, dated 20 and 29 April, appear in Carrell, Scorched Earth, 102, but they are not corroborated by other sources; Thach ('Kursk', 212-3) quotes these but confuses the 20 April message from 'Rot' with a different message for the same date cited by Carrell.
16. See Ernst Klink's excellent Das Gesetz des Handelns: Die Operation Zitadelle 1943 (Stuttgart 1966), 105-16 on the postponement to 9 May and 292-4 for Hitler's 'Operationsbefehl Nr. 6'.
17. A copy of Stalin's 'alert' directive of 8 May 1943, warning of a probable attack from 10-12 May, appears in V. Gurkin, 'Dokumenty i materialy: Podgotovka k Kurskom bitve', Voyenno-Istoricheskiy Zhurnal, No. 6, 1983 (June), 68; see also the memoirs of Sergei M. Shtemenko, wartime Chief of the General Staff of the Armed Forces of the USSR, or 'Stavka', The Soviet General Staff at War 1941-1945, trans. by Robert Daglish (Moscow 1970), 164-5, and Zhukov, Memoirs, 444. Gurkin's documentary collection also includes many key documents pertaining to the strategic decisions in April ('Dokumenty', 64-7).
18. The texts of these messages are reproduced in Schramm, Verrat, 356-9.

The planned transfer of armour to Italy is confirmed in Hitler's teletype to Field Marshal Erwin Rommel, 22 May 1943, reproduced on National Archives microfilm publication T78, Records of the German Army High Command (OKH), roll 343, frames 6301178-180 (hereafter cited in the format T78/343/6301178-180).

26. The statement was made by British journalist and wartime intelligence officer Malcolm Muggeridge, in an article in The Observer, January 1967 (West, Thread, 60).
27. The quotation appears in Read and Fisher, Lucy, 146; a similar conclusion appears in Richard Deacon, A History of British Secret Service, 2nd ed. (London 1980), 407. Among secondary works, John Ericson's The Road to Berlin (Boulder, Col. 1983), 65, 654, relies on Read and Fisher; Janusz Piekalkiewicz's Unternehmen Zitadelle (Bergisch Gladbach 1983), 63-8, 75, 91, 117, rejects the Lucy-Ultra link and does utilize some declassified Ultra intercepts, but extrapolates beyond their context to draw unwarranted conclusions.

44. On the crisis in German strategy in 1943, see Hubatsch, Kriegswende, 119ff. A serious debate on German occupation policy and war aims in Russia during the period December 1942-June 1943 also influenced Hitler in favour of a major offensive: see the author's 'The Politics of Illusion and Empire: The Attempts to Reform German Occupation Policy in the USSR, Autumn 1941-Summer 1943' (unpublished PhD dissertation, University of Maryland, 1985).
45. In August 1944, the German Army consolidated many of these observations into a handbook for general distribution: see Merkblatt 19/8, 'Truppen-Ic-Dienst im Osten vom 1.8.1944', in the National Archives Collection of Seized Enemy Records, RG 242, NA.
