Elyesa Bazna

Elyesa Bazna (Turkish: [ˈeljesɑ ˈbɑznɑ]), infrequently referred to as Iliaz^[2] and Ilyaz Bazna (Albanian: [iliaz bazna]),^[3] (28 July 1904 – 21 December 1970), was a secret agent for Nazi Germany during World War II, operating under the code name Cicero.

Born in Pristina, Bazna attended a military academy, and joined a French military unit at age 16. He was caught stealing cars and weapons, for which he served three years in a penal labor camp in France. Bazna held a number of manual jobs in Turkish and French cities before obtaining work for foreign diplomats and consulates as a doorman, driver, and guard. He spoke several languages fluently, including French, which was the predominant diplomatic language at the time. In 1943, Bazna was hired as a valet by Hughe Knatchbull-Hugessen, the British ambassador in Ankara, Turkey. He photographed British documents in Knatchbull-Hugessen's possession, and sold them to the Germans through their attaché Ludwig Carl Moyzisch in what became known as the Cicero affair.

As Cicero, Bazna passed on important information about many of the Allied leaders' conferences, including the Moscow, Tehran and Cairo Conferences. The details for the Tehran Conference were important for Operation Long Jump, the unsuccessful plot to kill Franklin D. Roosevelt, Joseph Stalin, and Winston Churchill. He had also conveyed a document that carried the highest security restriction (BIGOT list) about Operation Overlord (the code name for the Invasion of Normandy in June 1944). It included intelligence that the British ambassador was to request the use of Turkish air bases "to maintain a threat to the Germans from the eastern Mediterranean until Overlord is launched." The information about the Normandy Invasion was not known by the Germans until after the war. Had it been provided in time, Operation Overlord (the preparations for D-Day) could have been compromised. He also provided intelligence that might have made the Germans believe that there was no danger of attack in the Balkans. The information that he leaked is believed to have been among the potentially more damaging disclosures made by an agent during the Second World War. The German Foreign Office questioned the intelligence provided by Cicero due to the large quantity of transmitted documents, which meant that little, if any, of it was acted upon.^[4]

Once the British became aware that there was a spy operating within the Turkish Embassy, they investigated Bazna, installed a new alarm system, and initiated an unsuccessful sting to catch him selling intelligence. He stopped selling information to the Germans by the end of February 1944 and left the embassy within a month or so. After the war, Bazna was questioned for war crimes, but he was never charged with espionage. He attempted to buy and operate a hotel in Ankara with the proceeds of his spying career, but it was discovered that much of the money was counterfeit. He served a brief prison sentence for circulating forged notes. Bazna lived in Ankara with his family for many years and obtained work doing odd jobs. He moved to Munich in 1960 and worked as a night watchman before dying in 1970 of kidney disease. Bazna published a memoir of the Cicero affair in 1962.

Early life and family

Pristina around the turn of the century

Bazna was born in 1904 in Pristina, Kosovo Vilayet of the Ottoman Empire (now Kosovo). His parents were of Albanian heritage.^[5] His father was a teacher of Islamic doctrine and a landowner.^[6] He later stated that his father was a Muslim mullah named Hafiz Yazan Bazna, his uncle was Major General Kemal, and his grandfather was Tahir Pasha the Brave. Both his grandfather and uncle were Young Turks that served under Mustafa Kemal Atatürk.^[7][8]

When he was 14, Serbs occupied Bazna's birthplace and his family relocated during the defeat and dissolution of the Ottoman Empire^[6][7] to Istanbul,^[7] which was then occupied by British, Italian and American Allied forces of World War I.^[5] The Turkish National Movement (nationalists) opposed the occupying forces.^[5][7] Writer Yakub Kadri Karaosmanoğlu said that "the occupying forces in Istanbul considered all the cruelty and oppression committed by them against the people [of Istanbul] as lawful."^[5]

According to Bazna, he attended a military academy in Fatih, Turkey before 1919.^[7] At the age of 16, he joined a French military unit in Istanbul.^[5] He claimed to have stolen British weapons and cars for the Turkish National Movement, which was led by Atatürk.^[5][7] Richard Wires, author of Cicero, stated that Bazna was not motivated to steal for political or patriotic reasons.^[6] When he was caught stealing, Bazna was sent to a penal labor camp in Marseille, France for three years.^[5][7][9] He said that he worked at the Berliet motor company after he left the labor camp.^[7] While there,^[7] he learned locksmithing skills.^[7][10] In 1925, Bazna moved to Istanbul, where he worked for the Istanbul Corporation in the transportation department. He then worked as a fire brigade chief in Yozgat before returning to Istanbul to drive taxis.^[7]

Bazna spoke Turkish, Serbo-Croat and French,^[11] the latter of which was the standard language of diplomacy at that time.^[12] He also knew a little German from singing Lieder and said that he could read basic English but had difficulty speaking it.^[13] He was trained as an opera singer.^[14]

Bazna married twice; with his first wife, whom he later divorced, he had four children.^[5][9][15] He had several live-in mistresses, one of whom, Mara, was a nursemaid to the children of David Busk, a British ambassador.^[16] Mara lived with him in the Kavaklıdere hills in a small house that he called "Cicero Villa". Their relationship was tumultuous and Bazna ended the affair due to their fighting and her jealousy. However, she was loyal to him and passed important information to him twice, once about the upcoming arrival of British security men at the embassy and the second time when she said that she had heard rumors that the Germans had a good source of intelligence. Once he began seeing a new mistress, Esra, his relationship with Mara ended permanently.^[17] After Esra, he took a woman named Aika as his mistress and set her up in an apartment. She left after his pound notes were determined to be counterfeit.^{[18][lower-alpha 1]} He then married for a second time to a woman named Duriet and had four more children.^[15][19]

Espionage career

Background: Turkey during World War II

Turkey was neutral during much of World War II,^[20] although in October 1939, Britain signed a treaty to protect Turkey should Germany attack them.^[21][22] It maintained its neutrality by preventing German troops from crossing its borders into Syria or the USSR. During this time, Turkey had lucrative trade relationships with Germany and Britain.^[21][22] Germany had significant business interests in Turkey, including banks, and beginning in 1941 was reliant on chromite ore from Turkey for its armament production. In 1943, all of the chromite ore Germany imported for its weaponry came from Turkey.^[20] Throughout the war, Turkey's economy was reliant and prospered by virtue of its affiliation with both the Allied and the Axis powers. As a result, Turkey's gold reserve had risen to 216 tons by the end of 1945, from 27 tons at the beginning of the war.^[20]

Starting in 1942, the Allies provided military aid,^[21][22] and then they began imposing economic sanctions in 1943 to force Turkey to enter the war.^{[20][lower-alpha 2]} The western Allied powers wanted Turkey to become engaged in a fight against Germany's eastern flank; however, Turkey was afraid of being overrun by the Russian and German armies, both of which were led by dictators.^[27]

The Allied and Axis powers became increasingly involved in espionage in Turkey to protect their own strategic interests beginning in 1943. There were two Allied factions, the western Allies and the Soviet Union. Germany was the third entity engaged in intelligence gathering.^[27] The Germans were able to fund their espionage, propaganda, and diplomacy efforts from the profits of its banks in Turkey.^[20]

By August 1944, Turkey broke off relations with Germany, as defeat began to seem inevitable. In February 1945, it declared war on Germany and Japan, a symbolic move that allowed Turkey to join the emerging United Nations.^[21][22]

Employment by diplomats

Bazna worked for foreign diplomats and consulates as a doorman, driver, and guard upon his return to Turkey.^[4][5] Enabled by his ability to speak French,^[9] he served as a kavass^[7] or valet, first to the Yugoslav ambassador to Turkey.^[9] In 1942, he worked as a valet for Albert Jenke, a German businessman and later embassy staff member, who came to fire Bazna for reading his mail.^[9]

Before he worked for Sir Hughe Knatchbull-Hugessen in 1943,^{[lower-alpha 3]} Bazna was hired to do some household and vehicle repairs for Douglas Busk, the first secretary of the British Embassy. Due to Bazna's poor English, he answered all interview questions in French. Although he supplied some written biographical information, excluding having been employed and fired by Albert Jenke, none of the biographical information was checked. Turkish secret service apparently warned the embassy at some point about Bazna. Over the few months that Bazna worked for Busk, he secretly photographed a few documents and, with the help of Mrs. Busk's nursemaid named Mara, he tried to gain access to more valuable forms of intelligence.^[28]

Busk agreed to recommend Bazna for the open position of valet to Sir Hughe Knatchbull-Hugessen, the British ambassador to Turkey, who hired him in 1943^{[lower-alpha 3]} assuming that a background check had been performed.^[7][28][29] Knatchbull-Hugessen had been the British ambassador in Riga, Latvia until 1935.^[31]

Anthony Cave Brown, author of Bodyguard of Lies, wrote "Soon, Bazna had ingratiated himself to the extent that Sir Hughe elevated him from purely household duties to a position of some power within the residency and embassy. He dressed him in an imposing blue uniform, gave him a peaked cap, and used him as a guard to the door of his study; Bazna excluded visitors when Sir Hughe was thinking or napping. For ceremonial occasions, Sir Hughe dressed him in richly embroidered brocade, shoes with turned up toes, a fez with a tassel, gave him an immense scimitar, and placed him on the main door. Sir Hughe also paid him more than the 100 Turkish lira that was standard for a valet, and quietly turned a blind eye to the fact that Bazna was having an affair with Lady Knatchbull-Hugessen's handmaiden in the servants' quarters."^[14] Bazna often sang German Lieder after lunch while Knatchbull-Hugessen played the piano,^[14] much to the ambassador's enjoyment.^[14][32]

Beginning of espionage career

While at Riga, Knatchbull-Hugessen had developed a habit of taking secret papers to his home from the British embassy, and the ambassador continued that practice in Ankara.^{[lower-alpha 4]} Bazna gained access to documents in the ambassador's document box and safe using his locksmithing skills,^[32] including making impressions and then copies of the key for the document box.^[7] He began photographing secret documents about war strategy, troop movements, and negotiations with Turkey to enter the war.^[4][33] He took the photographs while the ambassador slept,^[4][34][35] took a bath, or played the piano.^[32]

Bazna approached the German Embassy in Ankara on 26 October 1943, indicating that he wanted £20,000 for two rolls of film of the ambassador's documents.^[4][33] He became a spy^[9] through the connection with his former employer, Albert Jenke. Jenke was the brother-in-law of Joachim von Ribbentrop, the German Foreign Minister. Although he was fired by Jenke, his wife contacted German intelligence officer Ludwig Carl Moyzisch and told him of the photographs that Bazna had taken of classified information at the British Embassy.^{[7][36][lower-alpha 5]} He became a paid German agent under Moyzisch and was given the Sicherheitsdienst (SD) code name "Cicero"^[4][39] by German Ambassador Franz von Papen due to Bazna's "astonishing eloquence".^[10] His Nazi paymasters made about one-half of his payments in counterfeit bank notes under Operation Bernhard.^[4]

According to Mummer Kaylan, author of The Kemalists: Islamic Revival and the Fate of Secular Turkey, Bazna said that he began spying for the Germans because he needed the money and, although he was not a Nazi, he liked Germans and disliked the British. He also alluded to involvement with the Milli Emniyet Hizmeti, which became the Turkish National Security Service in 1965.^{[40][lower-alpha 6]} The British historian Richard Wires wrote Bazna was motivated entirely by greed as he had dreams of becoming rich by selling secrets to the Germans.^[43] Bazna as a petty criminal from the Balkans was essentially apolitical and opportunistic, taking advantages of whatever chances he found to try to get rich.

Intelligence

Enigma cipher machine

During the first three months of 1944, Cicero supplied the Germans with copies of documents taken from his employer's dispatch box or his safe. Photographs of top secret documents were generally handed over in Moyzisch's car, which was parked inconspicuously on an Ankara street. On one occasion, this led to a high-speed chase around Ankara as someone had taken an interest in the hand-over. Bazna, who had perhaps been tailed, escaped.^[35] Ultra, the British codebreaking system based at Bletchley Park routinely read German messages, coded by the Enigma machine.^[44] From that information, the codebreakers knew that there was an intelligence breach, but did not know that the source was the British Embassy in Turkey.^[45]

Guy Liddell, who worked for MI5, recorded that there was a breach in security at the embassy on 17 October 1943, which was later reported by ISOS, Intelligent Service Oliver Strachey. The leak involved an embassy diplomat bag and two agents. On 3 November, Lilddell talked to Stewart Menzies,^[39] head of British Secret Intelligence Service.^[46] Through the discussion, Liddell learned that the leak of the diplomatic bag occurred during or after the air attaché brought it back from Cairo, which put not-yet-deployed re-ciphering tables at risk and required the abandonment of the tables. There were also missing blueprints for a gun at the office of a military attaché. Menzies stated that there was an investigation underway at the embassy, but nothing more was said about the leak for a few months.^{[39][lower-alpha 4]}

Allied leaders at the Cairo Conference held in Cairo, Egypt in November 1943. Seated are Generalissimo Chiang Kai-shek, Franklin D. Roosevelt, and Winston Churchill

As Cicero, Bazna passed on important information about many of the Allied leaders' conferences,^[30] including the Moscow, Tehran and Cairo Conferences.^[32][47] Fortunately for the British, Knatchbull-Hugessen only had possession of one document of notes from the conferences.^[47]

The intelligence provided by Cicero included a document instructing Knatchbull-Hugessen to request the use of Turkish air bases "to maintain a threat to the Germans from the eastern Mediterranean until Overlord is launched." The document carried the highest security restriction (BIGOT list).^[48] Cicero conveyed limited information about Operation Overlord (the code name for the Invasion of Normandy in June 1944),^[30] which was not correlated by the Germans until after the war when films about Cicero were released.^[49] According to the British Foreign Office's postwar review of Cicero's potential impacts: "It [Bazna's intelligence] provided the Germans with streams of information from the desk of the ambassador about British and Allied intentions in the Near and Middle East and for the conduct of the war generally, and might easily have compromised Operation Overlord (the preparations for D-Day)."^[50]

When the Cicero documents predicted Allied bombing missions in the Balkans, which took place on the predicted date, the authenticity of the information was supported and his reputation enhanced. Moyzisch told Cicero that at the end of the war Hitler intended to give him a villa.^[51]

Appraisal by the Germans

Copies of the developed film or summaries prepared by Moyzisch were promptly passed on to senior German leaders. Ribbentrop showed the initial set of photographs to Hitler immediately upon receipt. Hitler entered a conference with some Cicero materials in December 1943 and declared that the invasion in the west would come in spring 1944. He concluded, though, that there would also be attacks in other locations, such as Norway or the Balkans.^[52]

According to Moyzisch, the German Foreign Office did not make much use of the documents, because officers there were divided about their reliability^[53] for several reasons. There was a steady stream of documents, which was highly unusual. Cicero seemed to have used sophisticated photography techniques to create unusually clear images, which raised the question of whether he acted alone.^{[54][55][lower-alpha 7]} Antipathy between Papen and Ribbentrop added to the ineffective analysis of the intelligence.^[56] Aware of the Allied forces attempts to bring Turkey into the war, however, Papen was able to thwart their efforts for a time^[32] by threatening to destroy İzmir and Istanbul if Turkey declared war against Germany. Being able to postpone Turkey's alliance with the Allied forces and the use of their airfields, Papen told Ribbentrop that the way was now clear to take the Balkans.^[57]

Double agent hypothesis

The Abwehr was right to worry about the presence of British double agents within their secret service.^[58][59] They were at that time already running 'Garbo' (Juan Pujol), 'Zig-Zag' (Eddie Chapman) and 'Tricycle' (Dušan Popov), supposedly German agents to whom they were paying large sums of money, but who were in reality working for the British and were supplying the Germans with false information.^[59]

The head of British Secret Intelligence Service, Stewart Menzies, stated that Cicero was indeed a double agent and that among the documents submitted to the Germans were documents of misinformation.^[56] Author James Srodes states in his biography of Allen Dulles that some British historians believed that Cicero was "'turned' into a double agent to send disinformation via von Papen".^[60] Malcolm Gladwell, author of Pandora's Briefcase, said that an interviewer had questioned Menzies before he died about whether he was telling the truth. Menzies told the interviewer "Of course, Cicero was under our control," but his truthfulness is questioned.^[56][58] Gladwell stated in an article in The New Yorker; "if you had been the wartime head of M.I.6, giving an interview shortly before your death, you probably would say that Cicero was one of yours." Gladwell also mentions that while Ribbentrop was wary of Bazna, which curtailed the dissemination of some of Bazna's intelligence, most German intelligence officials were not wary of him.^[56]

Anthony Cave Brown suggests in his book Bodyguard of Lies that MI6's continental secret service chief, Lieutenant Colonel Montague Reaney Chidson, responsible for security of the embassy, would not have overlooked Bazna as a potential threat and may have fed the documents that Bazna in the ambassador's keeping or directly led Cicero as a double agent. Brown states that "Bazna was indeed under British control within a short time after he started to photograph the documents",^[61] and he was a participant in Plan Jael and Operation Bodyguard.^[58]

Mummer Kaylan states that through his personal knowledge of Bazna, he thought that Bazna supported Turkish interests and was not guided by British Intelligence. Further, he says that Bazna having passed on "genuine", "important" intelligence and the codeword for Operation Overlord to the Germans supports his theory that Bazna was not a double agent. If he was a double agent, Kaylan believes he was an agent for the Turkish Security Service, Milli Emniyet Hizmeti.^[46] Walter Schellenberg, too, wondered if Bazna passed on intelligence to the Turkish Secret Service.^[62]

Discovery of intelligence leaks

Fritz Kolbe, a German diplomat who became America's most important spy against the Nazis in World War II. Office of Strategic Services's Allen Dulles said of him, "George Wood (our code name for Kolbe) was not only our best source on Germany but undoubtedly one of the best secret agents any intelligence service has ever had."^[63] Kolbe identified that there was a spy operating out of a British Embassy in December 1943.^[64]

Fritz Kolbe, assistant to German diplomat Karl Ritter, screened German cable messages for information to summarize and supply to Allen Dulles, who was the Office of Strategic Services (OSS) chief representative in Bern. In late December 1943, Kolbe reported that there was a spy operating out of a British Embassy with the code name Cicero. Dulles forwarded this information to MI6 agent Frederick Vanden Heuvel on 1 January 1944.^[64] Cave Brown contends that Dulles passed the information to London in December. Since Bazna was about to carry out acts of espionage in December, Brown concludes that Bazna was likely a double agent.^[58][65]

American agents in Ankara investigated Cicero's identity based upon Dulles' intelligence.^[66] British intelligence, who were asked by Dulles to interrogate Cicero, gave the impression that they believed that Bazna could not speak English and, furthermore, was "too stupid" to be a spy.^[67] British Foreign Office workers, though, were concerned about Operation Overlord leaks and thought that Bazna might be Cicero. They implemented a sting in January 1944 using a false Cabinet Office document that was drafted by the chair of the Joint Intelligence Committee, Victor Cavendish-Bentinck and given the forged signature of Foreign Secretary Anthony Eden. The document was planted in the embassy, but the sting was unsuccessful in trapping Bazna.^[2][3]

About January 1944,^[68] Moyzisch hired a new secretary named Cornelia Kapp, also known as Nele Kapp, who had spied for the British and Americans in exchange for permission to immigrate to the United States.^[4][53] She had worked at the Germany embassy in Sofia, Bulgaria beginning in July 1943 and within a month had become a spy. In January 1944, she moved to Ankara to work at the German embassy under Moyzisch. Kapp was asked by the OSS to learn about the spy that Moyzisch met with. Kapp was adept at gathering intelligence within the office. She flirted with Cicero when he called the office to schedule a meeting with Moyzisch. When she could, Kapp also followed the two men to try to see what the spy looked like, but was unsuccessful at getting a good view of him.^[68] Kapp had gathered and shared a lot of information with the OCC over the months that she worked at the embassy, including all that she felt that she could learn about Cicero.^{[69][lower-alpha 8]}

Once the embassy had been tipped off that there was a spy operating in the facility in early 1944, Bazna found it increasingly difficult to gather intelligence.^[35][53] The British Field Office had warned the embassy of a security leak. Bazna forwarded the document to the Germans. The warning had come to Churchill from Roosevelt, who obtained the information given by a defector to the United States.^[32] A new alarm system in the British Embassy now required Bazna to remove a fuse whenever he wanted to look in the ambassador's safe.^[4]

Bazna gave notice about the third week of January 1944 that he would be leaving the ambassador's employment.^[29] He stopped selling information to the Germans by the end of February 1944^[4] and left the embassy at the end of the month^[29] or about 20 April^[70] without any trouble.^[71] Bazna was identified as Cicero after the war ended.^[72]

Potential consequences

In March 2005, British Foreign and Commonwealth Office historians issued The Cicero Papers, an analysis of the potential consequences of the 'Cicero Affair'. In it, they identified four important ways in which Cicero's intelligence could have harmed the Allied forces during World War II.^[47]

One of the key potential consequences was the possibility of alerting the German regime to the scope of Project Overlord. Fortunately, the location and the date of the planned invasion were not conveyed.^[47] The Allied forces wanted Turkey to declare war and join them in their efforts against Germany, particularly after they had taken the Dodecanese Islands and the Allies had secured Italy as a partner against Germany. Turkish airfields were important to maintain their strategic advantage in the area, particularly to support Operation Accolade, the British assault on Rhodes and the Dodecanese islands. With Cicero's intelligence, Papen was able to delay Turkey's entry into the war.^[47]

Bazna passed on the details for the Tehran Conference plans, which supported the unsuccessful Operation Long Jump plot^[73] to kill Franklin D. Roosevelt, Joseph Stalin, and Winston Churchill.^[74]

Once the British were aware of the leak, they were concerned that Cicero had leaked information that might help crack the British cipher, but that did not occur.^[47] Lastly, the intelligence might have made the Germans believe that there was no danger of attack in the Balkans, which may have been the most potentially damaging information gleaned by Cicero for the Germans.^[47]

After the war

After the war ended, the OSS conducted an investigation into Cicero, interviewing key German players including Moyzisch.^[66][72] It was postulated that of the intelligence conveyed by Cicero to the Germans, the most notable information came from Knatchbull-Hugessen's notes, particularly regarding diplomatic efforts with the Turkish government. Many of the other documents were considered by Ostuf Schuddekoft, head of the British section of Amt VI [one of the 11 departments of Hauptamt Volksdeutsche Mittelstelle], to be too old to be of much value to the Germans.^[72] Moyzisch was aggressively interviewed by the Allies and was a witness at the Nuremberg trials, after which he wrote a book to address rumors and explain his role during the war. He was never charged with a war crime.^[75]

Knatchbull-Hugessen's reputation was severely hampered by the Cicero Affair,^[72] particularly as he had been previously warned about leaving his keys and document boxes unattended. On 28 August 1945, Knatchbull-Hugessen received a formal, severe reprimand, but he was not court-martialed.^[76]

The Abwehr paid Bazna £300,000, or US$1.2 million, which he kept hidden.^[4] After the war he tried to build a hotel with a partner, but when his sterling notes were checked by the Bank of England, they were found to be mostly counterfeit (see Operation Bernhard).^[70][19] The spy remarked that the notes were "not worth even the price of the Turkish linen out of which they had been manufactured."^[70] Bazna served some time in prison for using counterfeit money.^[30]

Bazna lived in an apartment in the European Aksaray neighborhood of Istanbul with his family in the 1950s.^[15][77] He gave singing lessons and worked as a used car salesman^[15] and a night watchman.^[4] Much of the money he earned went to the creditors who had been paid with forged money.^[15] He contacted the West German government to be reimbursed for the counterfeit money that he received.^[53][78] Although he tried many times and in many ways to get a payment, he never received additional money.^[79]

In 1960, Bazna moved to Germany and worked in Munich as a night watchman.^[80] Bazna and Hans Nogly wrote I was Cicero, which was published in 1962. It told the story of the Cicero Affair from Bazna's perspective following Moyzisch's book Operation Cicero published in 1950.^[4] Bazna died in Munich of kidney disease in December 1970.^[80]

In popular culture

According to the British Foreign Office: "The tale has become a popular (and frequently mis-told) war story."^[50]

Moyzisch published his memoirs, titled Operation Cicero, in 1950.^{[30][lower-alpha 9]} Franz von Papen and Allen Dulles suggested that there was more to the story than was published in the book, but neither provided any details.^[53] Twelve years later, in 1962, I was Cicero was published by Cicero himself.^{[30][81][lower-alpha 9]}

A film based on the book Operation Cicero by Moyzisch was released by 20th Century Fox in 1952. It was titled 5 Fingers and directed by Joseph L. Mankiewicz. Bazna, renamed Ulysses Diello, was played by James Mason.^[82]
