“The Battle of Haifa, called by the Jewish forces Operation Bi’ur Hametz (Hebrew: מבצע ביעור חמץ “Passover Cleaning“), was a Haganah operation carried out on 21–22 April 1948 and was a major event in the final stages of the civil war in Palestine, leading up to the 1948 Arab-Israeli War.
The objective of the operation was the capture of the Arab neighborhoods of Haifa.”

“Maklef, who would become the third Israeli chief of staff, orchestrated the operation and gave orders to his troops in the Palestinian neighbourhoods (which, according to official Israeli records, were already empty of the Palestinians who had “left voluntarily”).
The Hagana Archives recorded: “When the bombardment of the neighbourhoods is concluded, troops will attack fiercely and aggressively and kill every Arab they meet. I am sending you flammable devices as well. You should burn every flammable object. I am sending you sappers with kits for breaking into houses” (3).
Adherence to these orders within the small area in which thousands of Palestinians lived produced panic. Without leadership, without any proper defence or any agency responsible for law and order (the British army’s responsibility), the people began a massive exodus; an instinctive, hasty departure, leaving personal and household possessions behind.
The masses surged towards the port, hoping to find a ship that would take them away from the city. The moment they left, their houses were pillaged.
By 22 April the streets near the port were jammed with desperate people looking for refuge and safety”

“Later, a series of laws passed by the first Israeli government prevented Arabs who had left from returning to their homes or claiming their property.
They and many of their descendants remain refugees.[13][14]
The expulsion of the Palestinians has since been described by some historians as ethnic cleansing,[15][16][17] while others dispute this charge.”[18][19][20]
