This first stage saw a bitterly fought campaign that culminated in a country-wide Zionist offensive dubbed Plan Dalet in the spring of 1948.33 Plan Dalet involved the conquest and depopulation in April and the first half of May of the two largest Arab urban centers, Jaffa and Haifa, and of the Arab neighborhoods of West Jerusalem, as well as of scores of Arab cities, towns, and villages, including Tiberias on April 18, Haifa on April 23, Safad on May 10, and Beisan on May 11. Thus, the ethnic cleansing of Palestine began well before the state of Israel was proclaimed on May 15, 1948.
