Antoine Khuraych headed the Maronite Church from his election on 3 February 1975 (enthronement 9 February) until 1986, styling himself the 'patriarch of dialogue'.

De Clerck and Malsagne and Traboulsi date the Sidon fishermen's protest to 26 February 1975. The marchers opposed Protein, a fishing company whose board included Camille Chamoun; their leader, Maarouf Saad, was shot and died some days later. Clashes between the army and armed groups in Sidon and Tyre followed at the start of March: de Clerck and Malsagne give 6 soldiers and 11 civilians killed and an army pull-out from Tyre, Hanf 5 soldiers and 11 civilians. The Kataeb staged a pro-army demonstration in Beirut. Hanf puts the fishermen's protest in March, and Picard describes the Sidon marchers as Palestinian militants.

Formed in September 1975 through Syria's foreign minister Abdel Halim Khaddam, the National Dialogue Committee of some twenty leaders debated secularism and ending sectarian quotas; Hanf says it broke up empty-handed.

Haugbolle notes widespread protests on National Day in November 1975; Hanf places the war's first demonstration in that month, when gunmen held fire until tens of thousands from East and West Beirut, summoned by television announcer Sharif Akhawi, had gone home.

Begun in late October 1975 (20 October in de Clerck and Malsagne's chronology), the Battle of the Hotels ran for five months, ending when the Holiday Inn fell on 20-22 March 1976. Traboulsi links its launch to Black Saturday in December.

Cardinal Paolo Bertoli's mission lasted from 9 to 14 November 1975 (de Clerck and Malsagne's chronology). Like the French envoy Couve de Murville, he backed a limited revision of the National Pact.

The bodies of four young Kataeb members were found on 6 December 1975, while Pierre Gemayel was in Damascus; Muslims seized at makeshift checkpoints by the port were killed in reprisal. Accounts place the bodies in the Metn (Hanf), near Tal al-Za'tar (Haugbolle) or outside the electricity company offices (Fisk). De Clerck and Malsagne blame Joseph Saadeh, whose son was among the four. Only Fisk puts Bashir Gemayel in Damascus and cites Phalangist officers saying he ordered the reprisal. The Muslim dead number about 200 (Hanf, Traboulsi, de Clerck and Malsagne) or several dozen (Picard); Fisk gives at least 300 Muslims, and probably as many Christians, in the reprisals.

Hanf has the Murabitun, discreetly backed by the Palestinians, going on the offensive against the Kataeb downtown and around the hotels on 8 December and seizing the Phoenicia and St Georges. Traboulsi places an army attempt to retake the two hotels on 9 December.

Bishop Yuhanna Bassul's diary records 500 shells hitting Zahleh on the night of 22 December, with some 15,000 fedayeen gathered in the plain; at his appeal the army's Maghawir commando regiment came to help. Hanf writes that 3,000 men of the PLA's Yarmouk Brigade had entered from Syria on 20 December and besieged the town, which Syrian positions also shelled.

On 11 March Brigadier-General Aziz al-Ahdab, Beirut garrison commander (retired, says Traboulsi), seized the television station, named himself interim military governor and called for Frangieh's resignation and an early election. Few troops stood behind him and Syria opposed him: on 15 March PLA and Saiqa units under Syrian control blocked his men and Khatib's Lebanese Arab Army on their way to Baabda. Backed by Chamoun, Gemayel and President Assad, Frangieh refused to go.

The deputies' petition demanding Frangieh's resignation is dated 11 March in Traboulsi's chronology and 13 March by de Clerck and Malsagne; Picard and Traboulsi's chronology count 68 signatures out of 99, Traboulsi's narrative 69. On 15 March Syrian-controlled PLA and Saiqa units halted a march on the Baabda palace by the Lebanese Arab Army and al-Ahdab's followers. Within days Khatib's force grew to a few thousand men and held most of the army's heavy weapons.

Mourabitoun and Palestinian fighters, backed by Lebanese Arab Army artillery, took the 24-storey Holiday Inn after a fight waged floor by floor, day and night, from 20 to 22 March 1976 (Traboulsi dates the fall to 22 March). The Kataeb withdrew to the Fattal building near the port. The five-month Battle of the Hotels was over, and Beirut was split along the Green Line.

Hanf traces the line that went on dividing the city along the Damascus road and across Martyrs Square to the harbour. It was set once the Kataeb, losing the Holiday Inn, had no positions left in West Beirut.

Historians date the entry of Syrian regular troops to 1 June 1976 (Ménargues gives 9 June). President Assad announced it in the presence of the visiting Soviet Prime Minister Kosygin, citing appeals from the Akkar villages of Qubayat and Andaqit, besieged since January and attacked by the Lebanese Arab Army on 27 May. Columns moved towards Akkar and Tripoli, Zahleh and the Bekaa, and Sidon by way of Jezzine. Estimates of the force range from 6,000 men at the start (with 260 armoured vehicles, according to Ménargues) to 12,000-15,000 within weeks, with 250-300 tanks (de Clerck and Malsagne).

In Beirut in early June, Hanf writes, Fatah and its allies turned on Saiqa, the PLA and the pro-Syrian parties and cleared them from the city within a few hours. Syria's regular army stayed outside the capital for now: on 7 June its troops got as far as Sofar on the Beirut-Damascus road and into Sidon, where an armoured column was wiped out. Syrian forces reached Beirut only in mid-November, within the Arab Deterrent Force.

Picard (2016) dates to 9 June 1976 the Arab League Council resolution, taken in Cairo, that created an Arab peace force. Hanf has some 2,000 Sudanese arriving first, then Libyans; Picard (2002) says Tripoli sent 500 men in June.

Fisk reports that the bodies of Ambassador Francis Meloy, his economic counsellor Robert Waring and their Lebanese driver, abducted near the Museum crossing, were found that evening at Ramlet al-Baida, and that Arafat, once sure of the three Palestinians responsible, sent them to Tyre. De Clerck and Malsagne judge that the murders ended American efforts at a settlement through the Lebanese parties.

Barely a tenth of American and British residents accepted the evacuation, Fisk writes. The British went by road, the PLO escorting them through West Beirut and a Libyan officer on to the Syrian lines; a day later a US landing craft took evacuees off from a PLO-guarded bathing club on the Corniche.

Sudan supplied the Arab peace force's first contingent, some 2,000 men, and Libya the next (Hanf).

Yara El Khoury dates the start of the final offensive on Jisr al-Basha and Tal al-Za'tar to 22 June 1976, and Hanf's account (Jisr al-Basha stormed eight days after the first assault, on 1 July) points to the same week. The camps had been blockaded since January. Hanf says Chamoun's Tigers and Christian units of the army led the attack, the Kataeb joining later; a joint command of Bashir Gemayel (Kataeb), Dany Chamoun and Nabil Karam (NLP), Fawzi Mahfouz (Tanzim) and Etienne Saqr (Guardians of the Cedar) coordinated it (de Clerck and Malsagne).

Hanf writes that Damascus thought the Christian side had won ground enough over the summer, so Syrian guns blocked the Lebanese Front's bid to cross the Beirut-Damascus road and take Aley. Kataeb fighters who had lost comrades at Aley the day before then killed Druze civilians at Salima (de Clerck and Malsagne).

Talks in France with the government and Mitterrand's opposition left Jumblatt sure that France could do nothing in Lebanon against Syrian and US opposition (Traboulsi). His tour, by boat from encircled West Beirut to Cyprus, then Cairo, Algiers and Paris, sought Arab contingents to offset the Syrians.

Ratified by an Arab summit in Cairo on 25 October, the Riyadh decisions required all parties to surrender heavy weapons and the Palestinians to return to the zones granted by the 1969 Cairo Agreement, and created a 30,000-man Arab Deterrent Force under President Sarkis, its largest contingent by far, 25,000-27,000 men, being the Syrian troops already in Lebanon. Saudi Arabia had sent the invitations on 15 October; the leaders of Saudi Arabia, Kuwait, Egypt, Syria and Lebanon met the PLO chairman in Riyadh on 16, 17 or 18 October, depending on the historian. The cease-fire's start is dated 16 October (Hanf), 21 October (Traboulsi) or 15 November (de Clerck and Malsagne).
