The day began with shootings near the church in Ain al-Rummaneh, where Pierre Gemayel was attending a consecration; his bodyguard Joseph Bou Assi was killed. In the early afternoon Kataeb militiamen fired on a bus returning to Tal al-Za'tar from a rally of the Arab Liberation Front. Most historians count 27 dead (Hanf, Fisk, de Clerck and Malsagne: 27 of 35 passengers); Traboulsi gives 21 and Ménargues 31. According to de Clerck and Malsagne the bus carried Palestinians and Lebanese in equal numbers, all men. Fighting spread that evening across the suburbs of Beirut.

After several days of fighting (Hanf; four, says Traboulsi), Pierre Gemayel gave up to the police two militiamen implicated in the Ain al-Rummaneh shooting. Early Syrian mediation failed to stop this round, which de Clerck and Malsagne end with a cease-fire on 16 May 1975; no book confirms a truce on 15 April.

In a heated sitting of parliament Rashid al-Solh resigned, blaming the Kataeb for the fighting. His refusal to deploy the army had led the Kataeb ministers to leave the cabinet, and other Christian ministers had followed them.

Nureddine al-Rifai was a retired Sunni officer: a general according to Hanf, a brigadier-general according to Traboulsi, an officer of the gendarmerie according to de Clerck and Malsagne.

The National Movement's call for a general strike, supported by the leading Sunni politicians, Mufti Hassan Khaled, Musa al-Sadr and Raymond Edde, brought down the military cabinet on 26 May; on 28 May Frangieh appointed Rashid Karami Prime Minister.

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.

Parliament used the truce to amend Article 73 of the constitution so that Frangieh's successor could be elected early: on 9 April according to Hanf, 10 April according to Yara El Khoury. The truce had coincided with the arrival on 31 March of the US envoy Dean Brown.

Traboulsi's chronology puts the Syrian-PLO accord to restore order in Beirut on 11 April. Around 9 April Syrian army tanks entered the Bekaa at Anjar, Judaydat Yabus and Bayadir al-Adas (Traboulsi), some forty in all according to Yara El Khoury, as Saiqa fighters set about ending the siege of Zahleh.

Accounts differ. Hanf has Raymond Eddé stand 'on principle', protesting at outside manipulation, and so become the Left's candidate; Traboulsi and de Clerck and Malsagne have him boycott the vote, Traboulsi because it could not be free.

Hanf and Ménargues count 66 votes for Sarkis out of 69 cast; de Clerck and Malsagne give 70. National Movement and PLO mortars fired as deputies, escorted by Saiqa, PLA or Syrian troops, met at the Villa Mansour on the demarcation line. Votes were reportedly bought, by Syria (de Clerck and Malsagne) or with Saudi and CIA money (Traboulsi). Sarkis was sworn in only on 23 September.

De Clerck and Malsagne note that Edouard Saab was Le Monde's correspondent too; a sniper shot him dead while he crossed the demarcation line.

De Clerck and Malsagne record three attempts on Raymond Eddé's life, one outside his home, before his voluntary exile in Paris from January 1977; Picard dates the exile to December 1976.

On 2 June Bashir Gemayel, having asked for a secret meeting with Kamal Jumblatt, offered him condolences and information on who had killed her. Traboulsi names her Linda al-Atrash and puts her apartment in East 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).

In 1976 Major Saad Haddad's force was known as the Army of Free Lebanon; it took the name South Lebanon Army only in 1985. Agreed through American mediation, the 'red line' kept Syrian and other Arab troops out of the south, where Palestinians and Christian militias kept fighting and Israel backed Haddad (Hanf).

Sami al-Khatib took over the ADF from Ahmad al-Hajj, who never won Syria's trust, and led it until 1983.
