In 1942-43 , he was the Haganah Commander in Haifa . Fulfilling also the office of commander of the Counterintelligence service - the " Ran " - and of the Intelligence Service - the Shin Yud - of the Haganah , he was involved in the conflicts between the Haganah and the other Jewish underground groups - Irgun and Lehi . Later , as Haganah 's link to these organizations , Irgun , helped them coordinate several missions with the Haganah . Among them the widely condemned attack at Deir Yassin . In 1948 , he was the local Haganah district commander when the village was attacked by Irgun and Lehi Jewish fighters despite a non-aggression pact signed between the Zionists and the Mukhtar of the village , the villagers wanting to remain neutral in the war . At first Shaltiel did not agree with attacking Deir Yassin , but after a day he surrendered and wrote a letter to them saying that he had " no objection to your carrying out the operation " . Yitzchak Levi , head of the Jerusalem branch of Haganah Intelligence , proposed that the inhabitants should be notified that the truce was over , but Shaltiel then refused to endanger the operation by warning them . He was also the mastermind behind Operation Kedem , which had the goal of capturing " East Jerusalem " . The mission was carried out July 8 , 1948 by Irgun troops and was a total failure . From that moment , he was , ( according to himself ) , disgraced and his name was erased from official Israel history
