The Arab revolt against the British had two different phases: the first one was led by the urban and elite Superior Arab Committee and focused on two strikes and political protests. The second phase began by the end of 1937 and consisted of violent attacks against the British forces.
The military actions began sporadically and became more organized through time. A particular target was the TAP pipeline, which extended from Kirkuk to Haifa and was built a few years before. It was blown up in many points of its trajectory. There were also many attacks on the railways (including trains), Jewish settlements (like the Jewish massacre in Tiberias). The violence began with a military attack on April/15/1936 against a convoy of trucks from Nablus to Tulkarm. The attack was carried out by followers of the deceased Al-Qassam, murdering two Jews: Israel Jazan and Tzvi Dannenberg. Meanwhile, the British convened the Peel Commission to analyze the causes of the violence because during those months the violence reduced its savagery. After the rejection from the Arabs to Peel’s proposal, violence started again during the autumn of 1937 and the British commissioner for Galilea (Lewis Yelland) was murdered in Nazareth. The violence continued throughout 1938 and started calming down in 1939. According to official British data, the military and the police killed more than 2.000 Arabs in combat (1936-1939), while 108 were hanged and 961 died because of what they described to be “gangs and terrorist activities”. In a British statistical analysis, Walid Khalidi estimated that there were 19.792 Arab victims with a total of 5.032 fatalities (3.832 were killed by the British and the other 1.200 died because of “terrorism”), and 14.760 wounded. These numbers are the result of the British-Arab conflict and not between Palestinian-Arabs and Jews.
