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.

Hanf puts the cabinet's formation at the end of June and its announcement some two weeks before the 15 July confidence vote (83 for, none against, 16 Jumblatt supporters abstaining); Traboulsi's chronology gives 6 July. Neither the Kataeb nor Jumblatt was included. A cease-fire followed, which Traboulsi says was reached with Syrian mediators' help.

Historians describe the Tripoli-Zgharta round as following the Zahleh fighting of late August: kidnappings on both sides, the killing of twelve Muslim bus passengers on the Beirut-Tripoli road, attacks on Christian villages in Akkar and the flight of Christians from Tripoli and Akkar. It ended when the army created a buffer zone between the two towns.

Hanf: Franjieh accepted Karami's condition for sending the army between Tripoli and Zgharta, Ghanem's removal; his replacement, Hanna Said, was a 'politically uncontentious' colonel.

De Clerck and Malsagne date the start of fighting in central Beirut to the night of 17-18 September 1975; Hanf and Traboulsi hold the Kataeb responsible for shelling the old souks. A cease-fire and the setting-up of the National Dialogue Committee followed.

De Clerck and Malsagne date the start of bread rationing to September 1975.

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.

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.

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 dates Lebanese Front forces' capture of the Jisr al-Basha camp to this day; de Clerck and Malsagne give 29 June, Picard August.

Hanf writes that once Jisr al-Pasha fell on 1 July the Palestinians struck in the north, taking coastal Chekka from Tripoli by way of the Koura, with massacres, looting and arson. A Lebanese Front counter-attack with army tanks reached Tripoli's outskirts.

Ménargues has William Hawi shot by a Palestinian sniper in June 1976, at the end of the Tal al-Za'tar siege; Traboulsi places it during the siege. Bashir Gemayel succeeded him as Kataeb militia chief.

Historians disagree on 1976: Haugbolle ranks it among the war's largest emigration waves, while de Clerck and Malsagne see many returning that year after nearly 400,000 Lebanese had left by 1975. Haugbolle notes that no official figures exist.

Ménargues dates the formal unification of the Christian militias under Bashir Gemayel's command to 31 August 1976; Yara El Khoury has it announced to President Frangieh in early September 1976. According to de Clerck and Malsagne, 'Lebanese Forces' was not the official name until 1981, but the unified command was officially founded on 25 March 1976.

Syrian helicopters and armoured limousines carried the 67 deputies to the Park Hotel in Chtaura, in the Syrian-held Bekaa, where 2,000 Syrian soldiers and 40 tanks guarded the ceremony (Fisk). Sarkis used his address to declare that Lebanon itself had invited the Syrian army in (Hanf).
