The Arab Revolt was the last major test of Britain's security services in the Middle East before World War II. The development and deployment of intelligence-led counterinsurgency strategies was integral to the restoration of British imperial control in Palestine as the revolt had demonstrated to the British authorities how a popular rebellion could undermine intelligence gathering operations and thereby impair their ability to predict and respond to inter-communal disorder. The rebellion had brought together urban nationalism and peasant economic grievances arising from rural poverty and landlessness, which was blamed on British misrule. Accordingly, the Palestinian revolt targeted the political and economic apparatus of the British colonial state, including the communications network, pipelines, police stations, army outposts and British personnel. It was this aspect of the revolt, rather than attacks on Jews or violence between rivals for leadership of the national movement, that most concerned the high commissioner. The mandate authorities were further disturbed by the unity of purpose displayed during the six-month general strike and by the resurgence of pan-Arab nationalism as evidenced by the rise of the Istiqlal Party.In response to these challenges the British army command ("I" Branch) and battalion headquarters across Palestine issued a daily intelligence bulletin every afternoon detailing political developments. Special Service Officers (SSOs) assigned to intelligence gathering reported directly to their local command headquarters and their cars were equipped with wireless transmitters so that high grade intelligence could be reported directly to "I" Branch immediately. These sources of intelligence gradually became more important than those of the C.I.D. in Palestine, which had been dependent on Arab informers, and which were no longer reliable.In September 1937, the Jewish Agency appointed Reuven Zaslany liaison officer for intelligence and security affairs between the Political Department of the Jewish Agency and the intelligence arms of the Royal Air Force and the C.I.D. Zaslany sifted through intelligence collected by Jewish-controlled field operatives and forwarded it to the British military. He was a frequent visitor at the headquarters of British intelligence and the army, the police and C.I.D. and he also travelled to Damascus to liaise with the Arab opposition's peace bands and with the British Consul in Iraq. Colonel Frederick Kisch, a British army officer and Zionist leader, was appointed chief liaison officer between the British army and the Jewish Agency Executive with Zaslany as his deputy. Zaslany also worked as interpreter for Patrick Domville, head of RAF Intelligence in Palestine (who was described by Haganah leader Dov Hos as the "best Zionist informer on the English"), until the latter was posted to Iraq in 1938, and through him became acquainted with many of the British intelligence officers.In 1937 the Jewish Agency's intelligence groups were responsible for bugging the Peel Commission hearings in Palestine. Eventually, the Arab Revolt convinced the Agency that a central intelligence service was required and this led to the formation of a counter-intelligence agency known as the Ran (headed by Yehuda Arazi, who also helped to smuggle rifles, machine guns and ammunition from Poland to Palestine) and thereafter in 1940 to the creation of SHAI, the forerunner of Mossad.
