Hermann Görtz arrived in Britain on 29 August 1935 with a secretary, Marianne Emig. They spent a few weeks in
Suffolk and eventually moved to
Broadstairs and rented a house. There they befriended British airman Kenneth Lewis and through him began to collect information about the
RAF Manston air base. Emig asked for letters of
Royal Air Force stationery and photographs of the planes and aerial views. When Lewis became concerned that he might be passing military information, she assured him that Britain and Germany would be on the same side in the next war. Lewis later testified that he was surprised at how much the couple already knew about the RAF. Near the end of their six-week tenancy, Görtz visited Germany and telegraphed his landlady Mrs Johnson that he would be gone for two days, asking her to take care of his belongings in the outhouse, including his "bicycle combination". Görtz had meant his
overalls, but Mrs Johnson thought he was referring to his
Zündapp motorcycle. Mrs Johnson checked the outhouse, did not find the motorbike and reported to police that it had disappeared. When police investigated the apparent theft, they found sketches and documents about Manston airfield. When Görtz returned to Britain three weeks later, police arrested him at
Harwich. Emig had stayed behind in Germany. Görtz was detained in
Brixton Prison. Police accused him of offences against the
Official Secrets Act (effectively for
espionage). The trial at the
Old Bailey began in March 1936 and attracted much publicity. Görtz pleaded
not guilty and claimed the documents were part of his research for an intended book about the growth of the RAF. He intended to write the book to pay off his creditors. Marianne Emig refused to come to England to testify for Görtz's defence, fearing she would be tried as well. According to evidence, including letters Görtz had sent his wife, it appeared that Görtz had been acting independently, possibly to impress the
German intelligence service. He had already unsuccessfully applied for a position in the
German Air Ministry. Further evidence also showed that he had been involved in the interrogation of Allied prisoners at the end of
World War I. Görtz was convicted and sentenced to four years of prison for espionage and sent to
Maidstone Prison. In February 1939, he was released and deported to Germany. The Abwehr eventually did employ him and he reached the rank of major. ==Plan Kathleen==
