First Lebanon War (1982-1985/2000)

The **1982 Lebanon War**, dubbed **Operation Peace for Galilee** by the Israeli government, later known in Israel as the **Lebanon War** or the **First Lebanon War**, and known in Lebanon as "the invasion", began on 6 June 1982, when the IDF invaded southern Lebanon, after repeated attacks and counter-attacks between the Palestine Liberation Organization (PLO) operating in southern Lebanon and the IDF that had caused civilian casualties on both sides of the border. The military operation was launched after gunmen from Abu Nidal's organization attempted to assassinate Shlomo Argov, Israel's ambassador to the United Kingdom. Israeli Prime Minister Menachem Begin blamed Abu Nidal's enemy, the PLO, for the incident, and used the incident as a *casus belli* for the invasion.

**Background**

### Relocation of PLO from Jordan to South Lebanon

After the 1948 Independence War, Lebanon became home to more than 110,000 Palestinian refugees, after their settlements in Palestine and Israel had been depopulated as a result of the war. After its founding in 1964 and the radicalization among Palestinians, which followed the Six-Day War, the PLO became a powerful force, then centred in Jordan. The large influx of Palestinians from Jordan after the Black September conflict caused an additional demographic imbalance within Lebanese society and its democratic institutions established earlier by the National Pact. By 1975, the refugees numbered more than 300,000 and the PLO in effect created an unofficial state-within-a-state, particularly in Southern Lebanon, which then played an important role in the Lebanese Civil War.

Continual violence near the Lebanese border occurred between Israel and the PLO starting from 1968; this peaked, following the relocation of PLO bases to Lebanon after the civil war in Jordan.

#### Immediate causes

From the ceasefire, established in July 1981, until the start of the war, the Israeli government reported 270 militant attacks by the PLO in Israel, the occupied territories, and the Jordanian and Lebanese border (in addition to 20 attacks on Israeli interests abroad).

In Ariel Sharon's biography by his son, Gilad Sharon, the author referring to the Habib ceasefire, comments: "However, the agreement was explicit only regarding preventing terror from Lebanon, which is why my father encouraged the cabinet not to accept the offer as presented by the Americans."

Arafat pressured the radical factions to maintain the ceasefire because he did not wish to provoke the Israelis into an all-out attack. The PLO acceptance of the ceasefire had led to dissension even within Fatah itself. A faction sympathetic to Abu Nidal forced a military confrontation, with accompanying arrests and executions — an event unprecedented in PLO internal disputes'. Arafat even attempted to distance himself from Palestinian unrest on the West Bank to prevent an Israeli attack. In contrast, Begin, Sharon and Eitan were searching for any excuse to neutralize their military opponents through a breach of the ceasefire. They believed that Arafat was buying time to build up his conventional forces. The Israeli interpretation of the conditions for the ceasefire placed responsibility for any act of Palestinian violence on Arafat's shoulders. It presumed that Arafat had complete control, not only over all factions within the PLO such as the rejectionist Popular Front of George Habash, but also over those outside such as Abu Nidal's Fatah Revolutionary Council and Ahmed Jibril's Popular Front — General Command. Moreover, in Begin's eyes, the ceasefire was not geographically limited to the Lebanese border. He argued that if Palestinian terrorism struck internationally, then this too would be regarded as a breach of the ceasefire. Begin thus took a stand-off in a local battle as applying to the entire war anywhere in the Middle East or any incident internationally. Eitan commented that there was no difference if a militant threw a grenade in Gaza or fired a shell at a Northern settlement — all such acts broke the ceasefire. Sharon similarly did not wish to draw distinctions between different Palestinian factions, since all blame had to be attached to the PLO. He dismissed attempts at more rational evaluation as masking the real issue. In a speech to a Young Herut conference in April 1982, he accused those who tried to take a more objective standpoint of erecting 'a protective wall around the PLO inside and outside Israel'.

Further support comes from George Ball, that the PLO had observed the ceasefire. Israel, he said, continued looking for the "internationally recognized provocation" that Secretary of State Alexander Haig said would be necessary to obtain American support for an Israeli invasion of Lebanon. Secretary Haig's critics have accused him of "greenlighting" the Israeli Invasion of Lebanon in June 1982. Haig denies this and says he urged restraint. In the biography of ceasefire broker Philip Habib, Alexander Haig is cited as leaving the worst impression of all in the lead up to Israel's Lebanon invasion:

The American reaction was that they would not apply any undue pressure on Israel to quit Lebanon as the Israeli presence in Lebanon may prove to be a catalyst for the disparate groups of Lebanon to make common cause against both Syrian and Israeli forces. Haig's analysis, which Ronald Reagan agreed with, was that this uniting of Lebanese groups would allow President Elias Sarkis to reform the Lebanese central Government and give the Palestinian refugees Lebanese citizenship. Additional evidence that the United States approved the Israeli invasion comes from longtime CIA analyst Charles Cogan, who says that he was in the room during a May 1982 meeting in The Pentagon during which Sharon explained to Secretary of Defense Caspar Weinberger "in great detail how the Israelis were going to invade Lebanon ... Weinberger just sat there and said *nothing*."

According to Avi Shlaim, the real driving force behind the Israeli invasion to Lebanon was the defense minister Ariel Sharon. One of his aims was the destruction of PLO military infrastructure in Lebanon and undermining it as a political organization, in order to facilitate the absorption of the West Bank by Israel. The second aim was the establishment of the Maronite government in Lebanon, headed by Bashir Gemayel and signing the peace treaty between two countries, the third aim was the expelling of the Syrian Army from Lebanon. Also, according to Shlaim, with the completion of Israeli withdrawals from Sinai in March 1982, under the terms of the Egyptian-Israeli Peace Treaty, the Likud-led government of Israel hardened its attitude to the Arab world and became more aggressive.

According to Zeev Maoz in *Defending the Holy Land: A Critical Analysis of Israel's National Security and Foreign Policy* the goals of the war were primarily developed by then Minister of Defense Ariel Sharon and were fourfold: 1) "Destroy the PLO infrastructure in Lebanon, including the PLO headquarters in Beirut." 2) "Drive Syrian forces out of Lebanon." 3) "Install a Christian-dominated government in Lebanon, with Bashir Gemayel as President." 4) "Sign a peace treaty with the Lebanese government that would solidify the informal Israeli-Christian alliance and convert it into a binding agreement." George Ball testified before the U.S: Senate's Foreign Affairs Committee that Sharon's long-term strategy, as revealed in conversations, was one of "squeezing the Palestinians out of the West Bank . .allowing only enough of them to remain for work."

The military plan with the code name "Big Pines", prepared by IDF, envisaged invasion to Lebanon up to the highway Damascus-Beirut and linking with Maronite forces. It was first presented to Israeli cabinet on 20 December 1981 by Begin, but rejected by the majority of ministers. According to Avi Shlaim, Sharon and chief of staff Rafael Eitan, realizing that there was no chance in persuading the cabinet to approve a large-scale operation in Lebanon, adopted a different tactic and intended to implement "Operation Big Pines" in stages by manipulating enemy provocations and Israeli responses.

On 3 June 1982 Israel's ambassador to the United Kingdom, Shlomo Argov was shot and seriously wounded in London by militants belonging to the Iraqi-backed Abu Nidal militant organization. The attack was ordered by the Iraqi Intelligence Service. Following the attack, the assassins drove to the Iraqi embassy in London, where they deposited the weapon. In his memoirs, Sharon stated that the attack was "merely the spark that lit the fuse". Israeli prime Minister Begin used this as the "internationally recognized provocation" necessary to invade Lebanon. The fact that the Abu Nidal organization was the longtime rival of PLO, that its head was condemned to death by the PLO court, and that the British police reported that PLO leaders were on the "hit list" of the attackers did not deter Begin. Iraq's motives for the assassination attempt may have been to punish Israel for its destruction of Iraq's nuclear reactor in June 1981, and to provoke a war in Lebanon that Iraqi leaders calculated would be detrimental to the rival Ba'ath regime in Syria—whether Syria intervened to help the PLO or not!

At the Israeli Cabinet meeting the following day, both Begin and Eitan belittled intelligence reports that the likely culprit was the Abu Nidal group. Begin cut short his own advisor on terrorism, arguing that all Palestinian militants were members of the PLO, while Eitan ridiculed the intelligence staff for splitting hairs and demanded to strike at the PLO. Yet Abu Nidal had broken with Arafat and PLO in 1974 over a fundamental principle: namely, that the Palestinian national movement would adopt a phased piecemeal approach to secure a Palestinian state and embark on a political path. The lack of understanding of the difference between Palestinian groups and the total ignorance of Palestinian politics on the part an overwhelming majority of Israelis and Jews played into the hands of those who did not wish to distinguish between the PLO and the Abu Nidal group. Thus, instead of an initiative to locate the Abu Nidal group in Damascus or Baghdad, the plan to invade Lebanon was activated.

The PLO denied complicity in the attack, but Israel retaliated with punishing air and artillery strikes against Palestinian targets in Lebanon, including the PLO camps. Sabra and the Shatila refugee camp were bombed for four hours and the local "Gaza" hospital was hit there. About 200 people were killed during these attacks. The PLO hit back firing rockets at northern Israel causing considerable damage and some loss of life.[*citation needed*] According to another source, twenty villages were targeted in Galilee and 3 Israelis were wounded.

According to Shlaim, Yasser Arafat, at that time being in Saudi Arabia, told the Americans through the Saudis that he was willing to suspend cross-border shelling. But that message was disregarded by the Israeli government. President Reagan also sent a message to Begin urging him not to widen the attack.

On 4 June the Israeli cabinet authorized a large scale invasion. Begin referred to the operation as self-defense to "avoid another Treblinka".

**The War**

### Invasion

On 6 June 1982, Israeli forces under direction of Defense Minister Ariel Sharon launched a three-pronged invasion of southern Lebanon in "Operation Peace for Galilee". Roughly 60,000 troops and more than 800 tanks, heavily supported by aircraft, attack helicopters, artillery, and missile boats, crossed the Israel–Lebanon border in three areas. Simultaneously, Israeli armor, paratroopers, and naval commandos set sail in amphibious landing ships from Ashdod towards the Lebanese coast north of Sidon. Israel's publicly stated objective was to push PLO forces back 40 kilometers (25 mi) to the north.

The westernmost Israeli force was to advance up the coastal road to Tyre. Its mission was to bypass Tyre and destroy three PLO camps in the area, then move up the coast towards Sidon and Damour, while Israeli forces would simultaneously conduct an amphibious landing north of Sidon to cut off the retreat of PLO forces there. In the center, two divisions were to advance both north and south of the high ground overlooked by Beaufort Castle, which was being used as a PLO stronghold, and take the road junction at Nabatieh, while an elite reconnaissance battalion was to take the castle itself. The two divisions were then to split, with one heading west to link up with the forces along the coast, and another towards Jezzine and from there along the right flank of Syrian forces in the Bekaa Valley. The easternmost Israeli force, the largest of the three, advanced into the Bekaa Valley. Its mission was to prevent Syrian reinforcements from being sent and to stop Syrian forces from attempting to interfere with the operation on the coastal road.

### Advance on Beirut

The advance along the coastal road was preceded by heavy artillery bombardment and airstrikes, but quickly became bogged down and was soon behind schedule. The narrowness of the road forced a slow advance, and Israeli armor became stuck in a large traffic jam. Several armored vehicles were knocked out by PLO fighters with anti-tank weaponry hiding in three groves along the road. One of the lead battalions, which was supposed to bypass Tyre and establish a blocking position to the north of the city, made a wrong turn and found itself in the center of the city, where it was ambushed. At eight in the evening the force finally crossed the Litani River and headed towards Sidon. In the central sector, the mission went as planned. The two Israeli divisions bypassed Beaufort Castle on both sides. Although an order to postpone the capture of Beaufort Castle was issued, it did not reach Israeli forces in time to prevent the operation, and Israeli troops of the Golani Brigade captured the castle in the fiercely-fought Battle of the Beaufort. The road junction at Nabatieh was also secured by the end of the first day. Meanwhile, the easternmost force penetrated into the Bekaa Valley and bore down on the Syrian positions. One division bypassed Mount Hermon via a road bulldozed by Israeli military engineers and cleared the town of Hasbaiya before swinging right and advancing towards Rachaiya. Though Israeli forces halted in the floor of the valley, they were flanking Syrian forces from the east and west. The Syrians put up minimal resistance and conducted some harassing artillery fire. By the end of the first day, the operation had gone almost entirely according to plan, though the advance along the coastal road was behind schedule.

Despite the delays, the Israeli advance along the coastal road continued steadily. This advance was supported by heavy air attacks against PLO positions that included the use of cluster bombs. Israeli missile boats also employed 76mm cannons to destroy targets along the coast, firing 3,500 shells during ten days of fighting. Israeli armor continued to advance towards Sidon, while other Israeli infantry attacked the three Palestinian refugee camps in the area that were used as PLO bases: Rashidiya, Burj ash-Shamali, and al-Bass. The camps were all crisscrossed with networks of bunkers, trenches, and firing positions. The Israelis took each camp section by section using the same method: warnings were blared by loudspeaker urging civilians to leave, before air and artillery bombardment commenced, followed by an infantry assault. Israeli infantry had to engage in fierce urban combat in narrow streets. The PLO defenders put up strong resistance and sometimes used civilians as human shields. It took four days of combat to secure Rashidiya and three days to secure the other two camps. At the same time, an Israeli amphibious operation was conducted north of Sidon, beginning with a diversionary bombardment of targets away from the landing zone by missile boats and aircraft. Two groups of commandos from the Shayetet 13 naval commando unit then came ashore to probe enemy defenses and secure the landing site, one of which swam to the mouth of the Awali River and another which came ashore on the landing beach in rubber dinghies. After a brief gunbattle with armed Palestinians, the main landings began, with paratroopers coming ashore in rubber dinghies to establish a beachhead followed by three landing craft that unloaded troops and armor. Over the following days, the three landing ships would run between Israel and Lebanon, shuttling more troops and armor onto the beachhead. The PLO response was limited to ineffective mortar fire, while Israeli missile boats and aircraft attacked Palestinian positions in response, and in total, about 2,400 soldiers and 400 tanks and armored personnel carriers were landed. From the beach, these forces advanced on Sidon, supported by naval gunfire from missile boats. At the same time, Israeli forces in the central sector advanced towards Jezzine while those in the eastern sector remained in place, but began setting up heavy artillery positions that put Syrian SAM units in artillery range.

Meanwhile, Israeli forces advancing along the coastal road reached the outskirts of Sidon, but were delayed by heavy resistance in the main streets and the Ain al-Hilweh refugee camp on the southeastern edge of the city, and after an attempt by paratroopers to capture the city center and secure the south-north route through the city failed, the city was bypassed via a detour through the hills to the east. After linking up with the forces that had landed north of Sidon, while another force of paratroopers and armor with heavy air and artillery support advanced through central Sidon and cleared a south-north route through the city in fierce fighting. Another Israeli division passed through the city to link up with the forces north of Sidon.

In the center, most Israeli forces advancing towards Jezzine bypassed the town to continue advancing towards the main highway in the area, leaving a blocking force in the area that was soon joined by an armored brigade. Fighting broke out in Jezzine between the Israelis and Syrian forces holding the town. In the Battle of Jezzine, Israeli forces consisting of two tank battalions supported by a reconnaissance company and engineering platoon took Jezzine in a fierce daylong battle against a Syrian battalion, then repulsed a fierce counterattack by dozens of Syrian commandos during the night in combat that lasted until dawn. Meanwhile, Israeli forces continued to advance along the Syrians' right flank.

Israeli forces advancing along the coast also completed the capture of Sidon. Paratroopers attacked the Kasbah while a combined force of Golani Brigade infantry and tanks attacked Ain al-Hilweh. The Kasbah was secured in three days; the paratroopers advanced cautiously and managed to take it without suffering any casualties. However, the fighting at Ain al-Hilweh was to prove some of the fiercest of the entire war. The camp was heavily fortified and defended by PLO fighters and Islamic fundamentalists. The defenders fought fiercely over every alley and house, with civilians who wanted to surrender shot by the fundamentalists. The Israeli advance was slow and was supported by massive air and artillery bombardment. The IDF employed its previous tactics of urging civilians to leave with loudspeakers before attacking an area. It took about eight days for the camp to fall, with the battle culminating in a last stand by the defenders at the camp mosque, which was blown up by the IDF.

In an effort to establish air superiority and greater freedom of action, the Israeli Air Force launched Operation Mole Cricket 19 on 9 June. During the course of the operation, the Israeli Air Force scored a dramatic victory over the Syrians, shooting down 29 Syrian planes and also destroying 17 Syrian anti-aircraft missile batteries, employing electronic warfare methods to confuse and jam the Syrian radars. The Israelis' only known losses were a single UAV shot down and two fighter jets damaged. Later that night, an Israeli air attack destroyed a Syrian armored brigade moving south from Baalbek, and the IAF attacked and destroyed six more Syrian SAM batteries the following day. The easternmost Israeli force, which had been stationary, resumed its advance forward up the Bekaa Valley.

In the center, Israeli forces were ambushed by the Syrians as they approached Ain Zhalta, and were pinned down by Syrian forces firing from superior positions. The Israelis were bogged down, and an infantry battalion was sent in by helicopter to reinforce them. The town was only captured after a two-day armored and infantry battle. The battle cost the Israelis 11 killed and 4 tanks, while the Syrians lost approximately 100 killed and 35 tanks. After Ain Zhalta fell, the Israelis advanced to the town of Ain Dara, which overlooked the Beirut-Damascus highway, and captured the heights overlooking the town. Along the road to Ain Dara, the Israelis encountered Syrian tank and commando units, and found themselves bogged down as the Syrians took advantage of the terrain. The Israelis called in air support, and Israeli attack helicopters that took advantage of ravines to fly in low beneath their targets to gain an element of surprise proved particularly effective against Syrian tanks. After a daylong battle, the Israelis had surrounded Ain Dara and were in a position to strike on the highway.

In the east, Israeli forces advanced along four main routes towards Joub Jannine, along both sides of the Qaraoun reservoir. The Syrians resisted fiercely. Syrian infantrymen armed with anti-tank weapons staged ambushes against Israeli tanks, and Syrian Gazelle helicopters armed with HOT missiles proved effective against Israeli armor. However, the Israelis managed to capture the valley floor, and the Syrians retreated. The Israelis captured Rachaiya, advanced through Kfar Quoq, and took the outskirts of Yanta. Joub Jannine also fell to the Israelis. The extent of Israeli advances ensured that Syrian reinforcements were blocked from deploying west of the Qaraoun reservoir. An Israeli armored battalion then probed past Joub Jannine to the town of Sultan Yacoub, and was ambushed by Syrian forces lying in wait. In the Battle of Sultan Yacoub, the Israelis fought fiercely to extricate themselves, and called in reinforcements and artillery fire to cover the withdrawal. After six hours, the Israelis managed to retreat, having lost 10 tanks and 3 armored personnel carriers. In addition, another major air battle erupted in which the Israeli Air Force shot down 25 Syrian jets and 4 helicopters.

To the west, as IDF troops mopped up remaining resistance in Tyre and Sidon, the Israeli advance on Beirut continued, and Syrian tank and commando units were then deployed south of Beirut to reinforce the PLO. When the Israelis reached the Beirut suburb of Kafr Sill, they met a joint Syrian-PLO force for the first time, and fought a difficult battle to take it. The IDF temporarily halted its advance in the western sector at Kafr Sill.

On 11 June, Israel and Syria announced that they had agreed to a cease-fire at noon, which would not include the PLO. The cease-fire was to come into effect at noon. Just before the cease-fire was to take effect, the Syrians moved a column of T-72 tanks so as to position it against Israeli forces in the valley. Israeli infantry teams armed with BGM-71 TOW anti-tank missiles ambushed the Syrian column, destroying 11 tanks. Another air battle also occurred, with the Israelis shooting down 18 more Syrian jets.

The Israeli advance on Beirut pressed forward in the west, reaching Khalde on 11 June. Six miles south of Beirut, the town was the last PLO position in front of Beirut Airport. The Israelis, who stood on the outskirts of Beirut, advanced towards the airport, and engaged in frequent combat with PLO and Syrian units as Israeli warplanes continued to bomb PLO positions in Beirut. The PLO's situation gradually grew worse as the Israeli advance gained ground, threatening to trap the PLO and a Syrian brigade deployed with them in the city. With the Israelis advancing on the south and the eastern sector of Beirut held by Lebanese Christian forces, the only way out was on the Beirut-Damascus highway, and the Israelis were building up forces at Ain Dara in the eastern sector, which were in a position to strike at the highway and block any PLO attempt to escape. On 12 June, the Israeli-Syrian cease-fire was extended to the PLO. As the Israeli advance halted, the Israelis turned their attention to the zone they already occupied in southern Lebanon, and began a policy to root out any PLO remnants. Israeli troops began searches for arms caches, and suspected PLO members were systematically rounded up and screened, and taken to a detention camp on the Amoun Heights.

On 13 June, less than twelve hours after the Israeli-PLO ceasefire had gone into effect, it fell apart, and heavy fighting erupted around Khalde. As the fighting raged, an IDF armored unit struck northeast, attempting to bypass Khalde and advance on Baabda, which overlooked the airport and could be used as another staging point to cut the Beirut-Damascus highway. By 14 June, Syrian forces were being deployed to Khalde. Syrian units in Beirut and three commando battalions armed with anti-tank weaponry took up defensive positions southwest of the airport to block any Israeli attempt to capture it. The Israelis attempted to flank these defenses by moving off the road past Shuweifat, up a narrow, steep, and winding road towards Baabda, but were ambushed by a Syrian commando battalion. The Syrians attacked Israeli armor with rocket-propelled grenades and anti-tank missiles at close range. Israeli infantry dismounted and engaged the Syrians. Fierce fighting took place, with the Israelis calling in artillery at very close range to themselves. The Israelis advanced relentlessly, and after fourteen hours of fierce combat that raged up through Ain Aanoub and Souq el-Gharb, they broke through the Syrian positions and entered Baabda. The IDF then immediately sent reinforcements to the column in Baabda to enable it to carry out further operations. From Baabda, the Israeli force split into three columns, one of which struck across the highway and entered the mountainous area to the northeast, one swung west and took up positions in the steep hills west of Beirut, and one turned toward Kahale, which was further down the highway. To the south, the IDF drove PLO forces out of Shuweifat, but no major battles occurred. The Israelis had now cut the Beirut-Damascus highway, cutting off all PLO and Syrian forces in the city.

On 15 June, Israel offered free passage to all Syrian forces in Beirut if they would withdraw from the city to the Bekaa Valley in the east, but the Syrian government refused and sent further reinforcements to its units along the highway and north of the highway near Beirut. The Israelis faced Syrian strongpoints reinforced by armor and artillery all along the highway. However, between 16 June and 22 June, the fighting was limited to artillery duels and minor firefights between Israeli and Syrian forces, as both sides reinforced their troops.

### Battles of the Beirut-Damascus highway

As the two sides prepared for combat, the IDF deemed capturing the Beirut-Damascus highway to be of critical importance. With the Syrians in control of most of the highway, occupying the towns along the highway and to the north, the Israelis could not prevent Syrian and PLO forces from escaping or launch further operations into Beirut without risking a Syrian flanking attack, and the Israelis also wanted a clear transit to Christian-held eastern Beirut.

On 22 June, the IDF launched an operation to capture the highway. The Israeli Air Force flew highly effective missions against Syrian positions and vehicles, with Israeli pilots reporting 130 enemy vehicles destroyed in a single air attack alone. Israeli long-range artillery targeted Syrian strongpoints to the north. Israeli armored forces with artillery support attacked Syrian positions along the highway, with the objective of driving them from the highway all the way back to the edge of the Bekaa Valley. With air and artillery support mostly limited to targets north of the highway, the fighting was fierce, especially to the south. By the end of the day, Israel accepted an American request for a cease-fire and halted its offensive, but the cease-fire collapsed the following day and the fighting resumed. As the Israelis pushed forward, and managed to trap a large Syrian force, Syrian defenses began to collapse. For the first time in the war, Syrian troops began to break and run. At Aley, which was defended by Iranian volunteers sent to fight for the PLO, the Israelis encountered fierce resistance.

The Israelis managed to push to the eastern Bekaa Valley, and on 24 June, began to shell the outskirts of Chtaura, which was at the northern mouth of the Bekaa Valley and served as headquarters of all Syrian forces there. It was also the last major obstacle before the Syrian border, as well as Syria's capital Damascus itself. The Israelis managed to reach the mountain pass near the village of Dahr el-Baidar, which was the last obstacle before Cthaura. The Syrians fought fiercely to hold the pass, and the Israeli advance halted, with the Israelis holding their ground and harassing the Syrians with artillery fire. By 25 June, with the remaining Syrian positions on and north of the highway no longer tenable, the Syrians withdrew. The Israelis allowed the withdrawal to occur but conducted artillery harassment and continued to shell the outskirts of Chtaura. The Syrians attempted to deploy a SAM battery in the Bekaa Valley at midnight, but Israeli intelligence detected this, and the battery was destroyed in an Israeli air attack. By the end of the day, a cease-fire was announced. The Israelis stopped at their present positions.

### Siege of Beirut

The Siege of Beirut had begun on 14 June: Israeli forces had completed the encirclement of the city the previous day. The Israelis chose to keep the city under siege rather than forcibly capture it, as they were unwilling to accept the heavy casualties that the heavy street fighting required to capture the city would have resulted in. Israeli forces bombarded targets within Beirut from land, sea, and air, and attempted to assassinate Palestinian leaders through airstrikes. The Israeli Navy maintained a blockade on the port of Beirut with a ring of missile boats and patrol boats supported by submarines. The siege lasted until August, when an agreement was reached in August 1982. More than 14,000 PLO combatants evacuated the country in August and September, supervised by the Multinational Force in Lebanon, an international peacekeeping force with troops from the United States, United Kingdom, France, and Italy. About 6,500 Fatah fighters relocated from Beirut to Jordan, Syria, Iraq, Sudan, both North and South Yemen, Greece, and Tunisia—the latter of which became the new PLO headquarters. Israel withdrew its forces from west Beirut on 29 September, officially ending Operation Peace for Galilee. Philip Habib, Ronald Reagan's envoy to Lebanon, provided an understanding (i.e., assurance) to the PLO that the Palestinian civilians in the refugee camps would not be harmed. However, increased hostilities against the US resulted in the April 1983 United States Embassy bombing. In response, the US brokered the May 17 Agreement, in an attempt to stall hostilities between Israel and Lebanon. However, this agreement eventually failed to take shape, and hostilities continued. These attacks were attributed to Iranian-backed Islamist guerrillas. Following this incident, international peacekeeping forces were withdrawn from Lebanon.

**Final accords**

On 14 September 1982, Bachir Gemayel, the newly elected President of Lebanon, was assassinated by Habib Shartouni of the Syrian Social Nationalist Party. Israeli forces occupied West Beirut the next day. At that time, the Lebanese Christian Militia, also known as the Phalangists, were allied with Israel. The Israeli command authorized the entrance of a force of approximately 150 Phalangist fighters' into Sabra and the Shatila refugee camp. Shatila had previously been one of the PLO's three main training camps for foreign militants and the main training camp for European militants; the Israelis maintained that 2,000 to 3,000 terrorists remained in the camps, but were unwilling to risk the lives of more of their soldiers after the Lebanese army repeatedly refused to "clear them out." Between 460 and 3,500 civilians, mostly Palestinians and Lebanese Shiites were massacred by the Phalangists, who themselves suffered only two casualties. The Lebanese army's chief prosecutor investigated the killings and counted 460 dead, Israeli intelligence estimated 700–800 dead, and the Palestinian Red Crescent claimed 2,000 dead. 1,200 death certificates were issued to anyone who produced three witnesses claiming a family member disappeared during the time of the massacre. Nearly all of the victims were men. Israeli troops surrounded the camps with tanks and checkpoints, monitoring entrances and exits. Further, Israeli investigation by the Kahan Commission of Inquiry found that Ariel Sharon bore "personal responsibility" for failing to prevent the massacre, and for failing to act once he learned of the massacre. The Commission recommended that he be removed as Defense Minister and that he never hold a position in any future Israeli government. Sharon initially ignored the call to resign, but after the death of an anti-war protester, resigned as Israel's Defense Minister, remaining in Begin's cabinet as a Minister without portfolio.

**Further conflict and Israeli withdrawal**

Following the departure of the PLO and international peacekeepers, Islamist militants began launching guerrilla attacks against Israeli forces. Suicide bombings were a particularly popular tactic, the most serious being the Tyre headquarters bombings, which twice devastated IDF headquarters in Tyre, and killed 103 Israeli soldiers, border policemen, and Shin Bet agents, as well as 49–56 Lebanese. The IDF subsequently withdrew from the Shouf Mountains but continued occupying Lebanon south of the Awali River.

An increased number of Islamic militias began operating in South Lebanon, launching guerrilla attacks on Israeli positions and on pro-Israeli Lebanese militias. Israeli forces often responded with increased security measures and airstrikes on militant positions, and casualties on all sides steadily climbed. In a vacuum left with eradication of PLO, the disorganized Islamic militants in South Lebanon began to consolidate. The emerging Hezbollah, soon to become the preeminent Islamic militia, evolved during this period. However, scholars disagree as to when Hezbollah came to be regarded as a distinct entity. Over time, a number of Shi'a group members were slowly assimilated into the organization, such as Islamic Jihad members, Organization of the Oppressed on Earth, and the Revolutionary Justice Organization.

In February 1985, Israel withdrew from Sidon and turned it over to the Lebanese Army, but faced attacks: 15 Israelis were killed and 105 wounded during the withdrawal. Dozens of pro-Israeli Lebanese militiamen were also assassinated. From mid-February to mid-March, the Israelis lost 18 dead and 35 wounded. On 11 March, Israeli forces raided the town of Zrariyah, killing 40 Amal fighters and capturing a large stock of arms. On 9 April, a Shiite girl drove a car bomb into an IDF convoy, and the following day, a soldier was killed by a land mine. During that same period, Israeli forces killed 80 Lebanese guerrillas in five weeks. Another 1,800 Shi'as were taken as prisoners.

Israel withdrew from the Bekaa valley on 24 April, and from Tyre on the 29th. In June 1985, the IDF unilaterally withdrew to a security zone in southern Lebanon along with its principal Lebanese ally, the South Lebanon Army.

Despite this being considered the end of the war, conflict would continue. Hezbollah continued to fight the IDF and SLA in the South Lebanon conflict until Israel's final withdrawal from Lebanon in 2000.

**Investigation into violation of international law**

On 16 December 1982, the United Nations General Assembly condemned the Sabra and Shatila massacre and declared it to be an act of genocide. The voting record on section D of Resolution 37/123, which "resolves that the massacre was an act of genocide", was: yes: 123; no: 0; abstentions: 22; non-voting: 12. The abstentions were: Belgium, Denmark, France, Germany (Federal Republic), Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Sweden, United Kingdom, U.S., Canada, Australia, New Zealand, Israel, Ivory Coast, Papua New Guinea, Barbados and Dominican Republic. Some delegates disputed the claim that the massacre constituted genocide.

In 1982, an international commission investigated into reported violations of International Law by Israel during its invasion of Lebanon. Chairman was Seán MacBride, the other members were Richard Falk, Kader Asmal, Brian Bercusson, Géraud de la Pradelle, and Stefan Wild. The commission's report concluded that "the government of Israel has committed acts of aggression contrary to international law", that the government of Israel had no valid reasons under international law for its invasion of Lebanon, and that the Israeli authorities or forces were directly or indirectly responsible for the massacres and killings, which have been reported to have been carried out by Lebanese militiamen in Sabra and the Shatila refugee camp in the Beirut area between 16 and 18 September.

Following a four-month investigation, on 8 February 1983, the Kahan Commission submitted its report, which was released to the public by spokesman Bezalel Gordon simultaneously in Hebrew and English. It concluded that direct responsibility rested with the Gemayel Phalangists led by Fadi Frem, and that no Israelis were deemed directly responsible, although Israel was held to be indirectly responsible:

The decision on the entry of the Phalangists into the refugee camps was taken without consideration of the danger – which the makers and executors of the decision were obligated to foresee as probable – the Phalangists would commit massacres and pogroms against the inhabitants of the camps, and without an examination of the means for preventing this danger.
Similarly, it is clear from the course of events that when the reports began to arrive about the actions of the Phalangists in the camps, no proper heed was taken of these reports, the correct conclusions were not drawn from them, and no energetic and immediate action were taken to restrain the Phalangists and put a stop to their actions.
