The Altalena Affair was a violent confrontation that took place in June 1948 between the newly created Israel Defense Forces and the Irgun (also known as Etzel), one of the Jewish paramilitary groups that were in the process of merging to form the IDF. The confrontation involved a cargo ship, the Altalena, captained by ex-US Navy lieutenant Monroe Fein and led by senior Etzel commander Eliyahu Lankin, which had been loaded with weapons and fighters by the independent Irgun, but arrived during the murky period of the Irgun's absorption into the IDF. Nineteen Israelis (three IDF soldiers and sixteen Irgun members) were killed in the confrontation. The incident brought the newfound Israel to the brink of civil war.

History

As the British Mandate for Palestine was coming to an end, and following the United Nations General Assembly vote recommending the Partition Plan for Mandatory Palestine, which took place on 29 November 1947, Jewish leaders proclaimed the establishment of the State of Israel on May 14, 1948. The declaration of independence was followed by the establishment of a provisional government and the Israel Defense Forces (IDF). The process of absorbing all military organizations into the IDF proved complicated, and several paramilitary groups continued to be active outside the IDF. One of the largest groups, the Irgun, planned to ship weapons and fighters to the newly formed state. The plans included a ship renamed Altalena (a nom de plume of Zionist leader Ze'ev Jabotinsky) and a target date for the ship's arrival from Europe was set to mid-May 1948. The Altalena, former landing ship tank USS LST-138, organized by Hillel Kook (a.k.a., Peter Bergson) purchased by Irgun members Gershon Hakim, Abraham Stavsky, and Victor Ben-Nachum, was originally intended to reach Israel on 15 May 1948, loaded with fighters and military equipment.

Weapons valued at 153 million francs were donated by the French government, in accordance with a secret agreement approved by French Foreign Minister Georges Bidault. The exact text of the agreement has not been found, and the French motivation is unclear. However, it is known that Bidault was very concerned about the possibility of a Jordanian takeover of Jerusalem. Deputy Chief of Staff General Henri Coudraux, who was involved in the operation, told a 1949 inquiry that France had "reached a secret agreement with the Irgun, which promised it advantages if it were to come into power [in Israel]." He described the Irgun's representative in the negotiations, Shmuel Ariel, as "a terrorist who did not represent a legitimate organization and acted to take power by force."

According to Begin biographer Daniel Gordis, organizational matters took longer than expected, and the sailing was postponed for several weeks. Meanwhile, on 1 June, an agreement had been signed for the absorption of the Irgun into the IDF and one of the clauses stated that the Irgun had to cease all independent arms acquisition activities. Consequently, the Irgun informed the Israeli government about the Altalena.

The Irgun headquarters in Paris did their best to keep the Altalenas preparations for departure a secret, but it was difficult to conceal the movement of 940 men and the loading of a large quantity of arms and ammunition. It was feared that if the plans were discovered, attempts might be made to sabotage the Altalena at sea.

For this reason, when it raised anchor on 11 June, no cable was sent to the Irgun command in Israel, for fear that it would fall into the wrong hands. These precautionary measures proved fruitless, however, and the following day the BBC reported that the Altalena had sailed from Port-de-Bouc, France, in the direction of Israel with 940 Jewish volunteers and a large quantity of weapons on board.

The first truce in the 1948 Arab–Israeli War had also begun on 11 June and when the Irgun leaders in Israel learned through the BBC broadcast of the embarkation of the vessel, they feared that this breach of the truce conditions (i.e., the ban on bringing military equipment and fighters into the countryReport dated 16 September 1948 by the United Nations mediator on the observation of the truce in Palestine during the period from 11 June to 9 July 1948. ) would be discovered (though ultimately, these aspects of the truce were ignored by both sides). Menachem Begin decided therefore to postpone the arrival of the ship, and Irgun staff secretary Zippora Levi-Kessel sent a wireless message to the Altalena to stay put and await orders. A similar cable was sent to Shmuel Katz (member of the General Headquarters), who was then in Paris, but the ship had already departed the day before the message arrived.

On 15 June, Begin and his comrades held a meeting with government representatives, at which Begin announced that the ship had sailed without his knowledge and that he wanted to hold consultations on how to proceed. In his diary for 16 June, David Ben-Gurion, the head of the provisional government, wrote:

Yisrael [Galili] and Skolnik [Levi Eshkol] met yesterday with Begin. Tomorrow or the next day their ship is due to arrive: 4,500 tons, bringing 800–900 men, 5,000 rifles, 250 Bren guns, 5 million bullets, 50 bazookas, 10 Bren carriers. Zipstein (director of Tel Aviv port) assumes that at night it will be possible to unload it all. I believe we should not endanger Tel Aviv port. They should not be sent back. They should be disembarked at an unknown shore.

Galili informed Begin of Ben-Gurion's consent to the landing of the ship, adding a request that it be done as quickly as possible. Zippora Levi-Kessel then radioed the vessel to come in at full speed. The following day, a working meeting was held between Irgun representatives and Defense Ministry personnel. While the Irgun proposed directing the Altalena to Tel Aviv beach, Defense Ministry representatives claimed that Kfar Vitkin beach was preferable, as it would be easier to evade UN observers there. The ship was therefore instructed to make for Kfar Vitkin.

Confrontation with the IDF Intense negotiations between representatives of the provisional government (headed by Ben-Gurion) and the Irgun (headed by Begin) followed the departure of the Altalena from France. Among the issues discussed were logistics of its landing and distribution of the cargo. Whilst there was agreement on the anchoring place of the Altalena, there were differences of opinion about the cargo.Sinking the Altalena Ben-Gurion agreed to Begin's initial request that 20 percent of the weapons be dispatched to the Irgun's Jerusalem Battalion, which was still fighting independently. His second request that the remainder be transferred to the IDF to equip the newly incorporated Irgun battalions was rejected by the government representatives,Asael Lubotzky, Not My Last Journey, Yedioth Ahronoth, 2017, pp. 161–162. who interpreted the request as a demand to reinforce an "army within an army".

The Altalena reached Kfar Vitkin in the late afternoon of Sunday, 20 June, greeted by Menachem Begin and a group of Irgun members on shore. Irgun sympathizers from the nearby town of Netanya and residents of the fishing village of Mikhmoret gathered on the beach to help unload the cargo. After the ship dropped anchor, 940 passengers disembarked and were taken to an army camp for induction into the IDF. Arms were unloaded throughout the night. In all, 2,000 rifles, two million rounds of ammunition, 3,000 shells, and 200 Bren guns were unloaded at Kfar Vitkin. Concomitantly with the events at Kfar Vitkin, the government had convened in Tel Aviv for its weekly meeting. Ben-Gurion reported on the meetings which had preceded the arrival of the Altalena and was adamant that Begin hand over the weapons:

We must decide whether to hand over power to Begin or to order him to cease his separate activities. If he does not do so, we will open fire! Otherwise, we must decide to disperse our own army.

The debate ended in a resolution to empower the army to use force if necessary. Implementation was assigned to the Alexandroni Brigade commanded by (Epstein), which the following day surrounded the Kfar Vitkin area in two regiments equipped with armor and artillery. In addition, the Israeli Navy deployed three corvettes off Kfar Vitkin. Even issued the following ultimatum:

To: M. BeginBy special order from the Chief of the General Staff of the Israel Defense Forces, I am empowered to confiscate the weapons and military materials which have arrived on the Israeli coast in the area of my jurisdiction in the name of the Israel Government. I have been authorized to demand that you hand over the weapons to me for safekeeping and to inform you that you should establish contact with the supreme command. You are required to carry out this order immediately. If you do not agree to carry out this order, I shall use all the means at my disposal in order to implement the order and to requisition the weapons which have reached shore and transfer them from private possession into the possession of the Israel government. I wish to inform you that the entire area is surrounded by fully armed military units and armored cars, and all roads are blocked. I hold you fully responsible for any consequences in the event of your refusal to carry out this order. The immigrants—unarmed—will be permitted to travel to the camps in accordance with your arrangements. You have ten minutes to give me your answer.D.E., Brigade Commander

The ultimatum was made, according to Even, "in order not to give the Irgun commander time for lengthy considerations and to gain the advantage of surprise." Begin did not respond. Claiming he needed more time, he drove to Netanya to consult directly with government leaders. A standoff between the IDF and Irgun members at the beach ensued as a UN observation plane circled overhead and recorded the incident. Failing to reach an accord, Begin returned to the beach and conferred with his officers. As evening began, rifle fire broke out; which side fired first is a matter of dispute. Hillel Kook, an eyewitness, claimed it was the Irgun, which fired shots toward the sea to demonstrate their will to resist. As the fighting began, Begin fled to the Altalena in a rowboat, under fire from the corvettes offshore, and Captain Fein maneuvered the Altalena to shield Begin, enabling him to board safely. On shore, the Irgun fighters were compelled to surrender. The IDF suffered two dead and six wounded, while the Irgun suffered six dead and eighteen wounded.Daniel Gordis: Menachem Begin: The Battle for Israel's Soul In order to prevent further bloodshed, the residents of Kfar Vitkin initiated negotiations between Yaakov Meridor (Begin's deputy) and Dan Even which ended in a general ceasefire and the transfer of the weapons on shore to the local IDF commander.

Meanwhile, Begin ordered the Altalena to sail to Tel Aviv, where there were more Irgun supporters. At 9:35 p.m., the Altalena began cruising toward Tel Aviv. Many Irgun members, who had joined the IDF earlier that month, left their bases and assembled on the beach. Rumors began circulating that the Irgun was planning a military coup.

According to the book Altalena by journalist and political analyst , Ben-Gurion instructed the Israeli Air Force to sink the ship on the high seas, long before it approached the shore. This would have resulted in much greater loss of life aboard. Gordon Levett, a Mahal volunteer pilot, wrote in his book Flying Under Two Flags that Heiman Shamir, deputy commander of the Air Force, tried to convince non-Jewish pilot volunteers to attack the ship. However, three pilots refused to participate in the mission, one of them saying, "You can kiss my foot. I did not lose four friends and fly 10,000 miles in order to bomb Jews."
