Israeli Naval Campaign in Operation Yoav

Operation Yoav ran from October 15 to 22, 1948. The Israel Defense Forces launched it after Egyptian forces raided inter-kibbutz communications routes and attacked an Israeli convoy near the Hatta–Kharatiya gap, while Egyptian aircraft struck supply convoys between Dorot and Ruhama.[1][2] The operation's goals included opening a corridor to the Negev, cutting Egyptian lines of communication along the coast and the Beersheba–Hebron–Jerusalem road, and isolating Egyptian forces in the field.[2] The Knesset's account adds that the offensive was also motivated by Count Bernadotte's proposal to remove the Negev from Israel's boundaries, giving the operation both a military and a political dimension.[3]

Within this combined-arms offensive, the navy was assigned a supporting but essential role: acting against Egyptian vessels, bombarding coastal areas, and operating near enemy shores to help encircle Egyptian forces from the sea.[4] Egypt held an advantage in naval weapons and training, yet it did not impose the feared sea blockade or demonstrate decisive naval superiority during the war.[4] Israeli commando units also drew on methods associated with Italian and other World War II special-operations veterans, contributing to what a later study described as limited but notable wartime successes.[5]

From the campaign's opening nights, Israeli naval vessels patrolled off the Gaza Strip to prevent Egyptian forces from receiving supplies by sea and regularly shelled coastal installations.[1] Naval saboteurs operated under cover of darkness, cutting road and railway tracks north and south of Gaza, while several small combined naval-and-army operations helped keep Egyptian forces in the coastal strip cut off from reinforcement.[1] The corvettes INS Wedgwood (K-18) and INS Hagana (K-20) bore much of this operational burden, conducting patrols, coastal-security missions, bombardments of strategic targets, and naval engagements; Operation Yoav was among the campaigns in which they were most prominent.[4]

Not all early naval sorties succeeded. After intelligence indicated that an Egyptian ship was operating south of Gaza, naval demolition divers sailed aboard the patrol vessel Palmach on the nights of October 16 and 17 to attempt a sabotage mission.[4] They failed to locate the target on either sortie and returned without completing the attack.[4] A planned amphibious landing intended to neutralize an Egyptian artillery battery near Ashdod was also aborted. The Givati Brigade contributed 25 fighters and a six-person naval landing team aboard the patrol vessel M-23, but most of the soldiers were badly seasick by the time they reached the target area, and a technical fault aboard the vessel contributed to the commander's decision to cancel the operation.[4] The failure reinforced the need for a properly trained and equipped amphibious landing unit.

On October 19, 1948—the fourth day of Operation Yoav—the fledgling Israeli Navy fought what the Center for Israel Education identifies as its first major battle, off the coast of Ashkelon.[6] Accounts differ on the Israeli force's composition: the Center for Israel Education names Hagana (K-20), Wedgwood (K-18), and Noga (K-26), while the Jewish Virtual Library's volunteer history also lists Maoz (K-24).[6][7]

Both accounts describe an engagement with an Egyptian corvette and Egyptian aircraft. The volunteer history says the four ships faced three Spitfires, shot down one aircraft, and damaged the corvette before it escaped to Port Said.[7] By contrast, testimony reproduced by the Center for Israel Education reports that Hagana and Wedgwood each downed an Egyptian aircraft; it also records that one Hagana sailor was killed and five were wounded.[6] The volunteer history further states that all four vessels took part in October bombardments of Egyptian shore installations in the Ashkelon area and worked to prevent the Egyptian Navy from evacuating retreating forces.[7]

The most consequential Israeli naval asset during Operation Yoav was a specialist explosive-boat unit that traced its origins to the Palyam and was known internally as "the Cell."[8] The unit was an early precursor of what would later become Shayetet 13, Israel's elite naval commando force.[8]

The unit's weapons were flat-bottomed wooden motorboats purchased in Italy and capable of reaching 32 knots.[4] Each boat carried approximately 300 kilograms of explosives in its bow, detonated on impact through a projecting pole.[4][8] A single operator steered the craft toward its target and jumped into the water before detonation.[4] Italian naval veteran Fiorenzo Capriotti, who had operated similar craft during World War II, was recruited to train the Israeli operators on the Sea of Galilee.[4][8] Before Operation Yoav, the demolition unit was transferred to Jaffa, and Ma'oz—which had joined the fleet in September 1948—was prepared as the mother ship for six explosive boats.[4]

On the night of October 22, 1948—the final day of Operation Yoav—the explosive-boat unit carried out what was later described as the Israeli Navy's most impressive wartime naval operation.[4][9] The target was the Egyptian flagship Amir Faruk, rendered King Farouk in some accounts.[1][2] It was described as a heavy warship that had previously attacked Tel Aviv and whose crew had shot down an Israeli aircraft sent against it.[10] On the night of the attack, it was reportedly heading toward the Gaza Strip to deliver troops and supplies, accompanied by a second vessel.[10]

Three explosive boats and a rescue boat were carried to the scene aboard an Israeli naval vessel.[10] The operators were Yohai Ben-Nun, Zalman Abramov, and Yaakov Vardi; Yaakov Ritov and Yitzhak Bruckman crewed the rescue boat.[8] Abramov and Vardi steered their boats toward the flagship and jumped into the water before detonation; one operator ejected at approximately 50 meters rather than the intended 100.[10][8] Ben-Nun, commanding the third boat, pressed on under fire and struck the accompanying vessel. While trying to escape, he became entangled in a rope, which broke before it could trap him.[10][8]

Accounts differ on the accompanying vessel's fate. Mako says Ben-Nun destroyed it, while Ynet says that both Egyptian vessels began sinking.[10][8] Jewish Virtual Library histories instead describe an Egyptian minesweeper as damaged.[7][9] Ynet reports that some men aboard the vessels were killed and others drowned; it also describes Abramov being found on a float among Egyptian bodies and pulled aboard the rescue boat.[8]

The Israeli side did not immediately know the flagship's identity. According to the 1950/51 Israel Yearbook, only three days after the sinking did a United Nations statement relaying Egyptian sources identify the vessel as the King Farouk, described as the Egyptian Navy's flagship and pride.[1] Ben-Nun was subsequently awarded the Hero of Israel decoration.[8] A later Ynet account characterized the action as bringing Israel a measure of naval superiority and said that Egyptian ships ceased shelling the Israeli coast afterward.[8]

A United Nations Security Council cease-fire took effect on October 22, 1948, ending the campaign.[1] Operation Yoav opened the road to the Negev and cleared Egyptian forces from the northern Negev apart from the Gaza Strip and the Faluja pocket.[1] Beersheba was captured on October 21.[2]

The naval contribution was meaningful but secondary to the land and air operations. The Israeli Navy prevented supplies from reaching Egyptian forces in Gaza and Majdal by sea, bombarded coastal installations, and destroyed the Egyptian flagship on the campaign's final day.[2][7] The feared Egyptian sea blockade never materialized; despite Egypt's advantage in naval weapons and training, it was unable to establish maritime dominance during the war.[4] A Washington Institute study assessed the navy's wartime record as including limited but notable successes achieved through commando methods learned from Italian and other special-operations veterans.[5]

The sources agree on the campaign's broad outline but differ on important details. The flagship appears as Amir Faruq in the Operation Yoav account and Emir Farouk in The Jerusalem Post.[2][11] The Israel Yearbook and the naval-volunteers history use King Farouk or King Farouq.[1][7] Location descriptions also conflict: The Jerusalem Post places the ship outside Tel Aviv harbor, while Ynet situates the sinking off Israel's southern coast.[11][12] Other accounts place the action off Gaza or in the Ashkelon–Gaza coastal area.[2][7]

Command and the fate of the accompanying vessel are likewise described differently. The Jerusalem Post places three motorboats under Paul Shulman, while the detailed Mako account identifies Yohai Ben-Nun as commander of the explosive-boat force.[11][10] Mako and Ynet describe the accompanying vessel as destroyed or sinking, whereas Jewish Virtual Library histories say a minesweeper was damaged.[7][10]

The Operation Yoav account and Mako explicitly present the sinking as a final-day naval action within the campaign.[2][13] Other general accounts date the action to October 1948 without explicitly connecting it to Operation Yoav.[11][12] The Israel Yearbook uses celebratory language and describes casualties aboard the flagship as "heavy" without providing a number.[1] Its reproduced text also contains an apparent date anomaly, placing the assault on Beersheba after the October 22 cease-fire, while the Operation Yoav account dates the city's capture to October 21.[1][2]
