Operation Nachshon

Core idea: Operation Nachshon (April 1948) was the first large-scale military operation explicitly implementing plan-dalet — aimed at clearing the road from Tel Aviv to Jerusalem by depopulating Palestinian villages along the corridor, establishing the operational template of village-by-village ethnic cleansing that would be replicated across all of Palestine in the following months.

The Objective

The western slopes of the Jerusalem mountains, halfway along the road to Tel Aviv, were the first area chosen for putting Plan Dalet into action. The road to Jerusalem passed through numerous Palestinian villages, and the Zionist leadership needed to secure this corridor both to supply the Jewish population in Jerusalem and to demonstrate that the systematic cleansing was operationally feasible.

Every brigade assigned to Nachshon was asked to move into Mazav Dalet — State D — meaning: “You will move to State Dalet, for an operative implementation of Plan Dalet.” The opening sentence to each unit was unambiguous. What followed was: “the villages which you will capture, cleanse or destroy will be decided according to consultation with your advisors on Arab affairs and the intelligence officers.”

The Method

The Palmach units received their orders on April 1, 1948. The Consultancy had met the night before at Ben-Gurion’s house to finalize directives. The orders were clear: “the principal objective of the operation is the destruction of Arab villages… and the eviction of the villagers so that they would become an economic liability for the general Arab forces.”

The operational template established during Nachshon became standard:

  1. Encircle the village
  2. Conduct a “combing” search
  3. Separate men of “military age” (10-50) from women and children
  4. Use hooded informers to identify men from the village-files target lists
  5. Execute selected men or send them to POW camps
  6. Expel the remaining population
  7. Demolish houses and plant mines in the rubble to prevent return

The Villages

One by one, the villages along the Jerusalem corridor fell into Jewish hands. The Qastal — a village with ancient fortifications on the last western peak before Jerusalem — was among the first. The paramilitary groups of Abd al-Qadir al-Husayni put up more resistance than expected, but by April 9 the campaign was over. Al-Husayni himself was killed defending the Qastal, and his death demoralized Palestinian fighters across the Greater Jerusalem area. Villages were then surrounded, attacked, occupied, their people expelled and buildings demolished in rapid succession.

It was also during Nachshon, on April 9, that the deir-yassin-massacre occurred — carried out by Irgun and Stern Gang forces as the Hagana operated nearby. The massacre served as a force multiplier: news of Deir Yassin accelerated flight from dozens of surrounding communities, making the Hagana’s job easier.

Nachshon was also a novelty in other respects: it was the first operation where all Jewish military organizations (Hagana, Palmach, Irgun, Stern Gang) acted together as a single army, providing the operational basis for the future Israeli Defense Forces.

Key Insight

Operation Nachshon matters because it was the proof of concept — the first time Plan Dalet moved from paper to ground, demonstrating that the systematic ethnic cleansing of an entire country was operationally feasible, one village at a time, and establishing the template every subsequent brigade would follow.
