though publicly deplored and criticised by the principal Jewish authorities, had a deep impact on the morale of the Arab population and contributed to generate the exodus of the Arab population. At the same time, the Arab Liberation Army was roundly defeated at Mishmar HaEmek in its first large-scale operation, coinciding with the loss of their Druze allies through defection. Within the framework of the establishment of Jewish territorial continuity foreseen by Plan Dalet, the Haganah, Palmach and Irgun forces intended to conquer mixed zones. The Palestinian Arab society was shaken. Tiberias, Haifa, Safed, Beisan, Jaffa and Acre fell, resulting in the flight of more than 250,000 Palestinian Arabs. The British had, at that time, essentially withdrawn their troops. The situation pushed the leaders of the neighbouring Arab states to intervene, but their preparation was not finalised, and they could not assemble sufficient forces to turn the tide of the war. The majority of Palestinian Arab hopes lay with the Arab Legion of Transjordan's monarch, King Abdullah I, but he had no intention of creating a Palestinian Arab-run state, since he hoped to annex as much of the territory of the British Mandate for Palestine as he could. He was playing a double game, being just as much in contact with the Jewish authorities as with the Arab League.

Armed forces By September 1947, the Haganah had "10,489 rifles, 702 light machine-guns, 2,666 submachine guns, 186 medium machine-guns, 672 two-inch mortars and 92 three-inch (76 mm) mortars". Importing arms In 1946, Ben-Gurion decided that the Yishuv would probably have to defend itself against both the Palestinian Arabs and neighbouring Arab states and accordingly began a "massive, covert arms acquisition campaign in the West", and acquired many more during the first few months of hostilities. The Yishuv managed to clandestinely
