The Secret History of MI6 - Keith Jeffery [343]
A possible additional source of information was Mao Zedong’s Chinese Communists. Although the Communists and Nationalists had formed an uneasy common front against the Japanese in 1937, internecine hostilities had resumed from early 1941 and any British contacts with the Communists had to proceed with considerable discretion. In mid-July 1942 Gordon Harmon in Chungking reported that he had been visited by the private secretary of General Zhou Enlai, the ‘political head of the Chinese Communist Party’, who gave ‘evidence of a really genuine desire to co-operate against the Japanese’. The Communist emissary handed over a report which, although ascribed to human sources, was clearly derived from signals intelligence. It described a major reorganisation of Japanese intelligence in China and was an intercept of a message from the Japanese embassy accredited to the puppet regime in Nanking to the Japanese consulate-general in Hankow (Hankou). Harmon wisely noted that he had to be ‘extremely careful in contacts with this organisation’. In London, Section V thought the source ‘seems very promising’. Alastair Denniston of GC&CS confirmed that part of the message had been received in Bletchley Park but not the rest, and while the Admiralty had ‘no means of checking the truth’ of the report, they thought it ‘very likely’ and were ‘prepared to believe it’. Although Chungking reported in August a further contact promising ‘a considerable amount of information’ and a personal message from Zhou Enlai that he ‘wished to collaborate closely in Anti-Japanese effort’, the source appears to have dried up shortly thereafter. An attempt the following year to extend coverage in China and possibly develop contacts with the Communists was neatly thwarted by the Nationalists. SIS proposed to send Frank Hill, the former head of station at Peking to open a new post in Sian (Xi’an), 350 miles north-west of Chungking and a centre of Communist activity. Taking a necessarily circuitous route because of the war situation, Hill was allowed by the Nationalists to travel only as far as Chengtu (Chengdu), actually further from Sian than Chungking. London reckoned that Hill had queered his pitch with the Kuomintang by having already made indiscreet contacts with Communists in Chungking, and so they wanted him safely out of harm’s way. In the event Hill’s health deteriorated and he was withdrawn in October 1943.
Although SIS was ostensibly working alongside allies, China proved to
