Prior to the establishment of the state of Israel the leader of the Yishuv, David Ben-Gurion, made several attempts to reorganise the main underground militia, the Haganah, and its elite force, the Palmach. In 1948 this led to a series of confrontations between Ben-Gurion and leaders of the newly formed Israeli army, which became known as "The Generals' Revolt".
Ben-Gurion had three objectives:
In 1946 Ben-Gurion tried to appoint loyal supporters into the upper echelons of the Haganah but was unsuccessful. The following year, there was a debate within the defence establishment about what form of armed forces the Yishuv should have in the anticipated conflict. Ben-Gurion proposed an entirely new organisation to replace the Haganah, modelled on the British Army. These new ideas shocked the Haganah leadership. The Haganah had not been active since withdrawing from direct action against the British authorities in July 1946, and the crisis threatened morale within Haganah units. Rather than damage the existing structures, Ben-Gurion allowed his ideas to be dropped.
In April 1948, while Chief of Staff, Yaakov Dori, was absent due to ill health, Ben-Gurion came to the decision to abolish the post of Head of National Command, and give himself, as Minister of Defence, direct control over the General Staff. This post was held by Israel Galili, one of the leaders of Mapam, the pro-Soviet rivals to Ben-Gurion's Mapai party. On 26 April Ben-Gurion notified Galili of the decision. After Galili raised objections, on 3 May, Ben-Gurion issued an official letter:
". . . The post of head of the national command is hereby abolished, and Israel Galili's appointment to the post is terminated. The staff of the security forces will henceforth receive its instructions exclusively from the director of security [Ben-Gurion himself] or his representative."
A majority of senior IDF officers at that time were from Mapam, and the response from several of them was to threaten to resign. Mapam's newspaper, Al Hamishmar, predicted the result would be "a personal dictatorship." On 6 May the Haganah leadership presented Ben-Gurion with an ultimatum:
