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 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.

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.

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.

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.

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.

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.

Hanf puts the entry of about 6,000 Syrian soldiers, in the peace force's green helmets, into East and West Beirut on 14 November. Fisk's report in The Times of 16 November dated their occupation of the whole city to the previous morning, with 6,000 men and hundreds of tanks; the last firing, near the port, ended on 16 November, Fisk recounts.

Historians date the Ehden killings to 13 June (de Clerck and Malsagne) or 14 June (Hanf). A unit of some 200 men (Traboulsi) led by Samir Geagea attacked the Frangieh residence; besides Tony Frangieh, his wife and their three-year-old daughter, about thirty relatives and supporters were killed. The Phalange presented the raid as retaliation for the killing of their local leader Jud al-Bayeh in early June; Bashir Gemayel denied ordering the killing of the family. The raid also turned on control of the Chekka cement works. Syrian troops then occupied Ehden and much of the north.

De Clerck and Malsagne date the end of the shelling to 7 October. On that day President Sarkis asked in public for the Arab Deterrent Force's mandate, due to lapse on 28 October, to be extended, and Syria maintained its blockade until the renewal.

Ménargues writes that when the Moukafaha, Johnny Abdo's own intervention unit, arrested Elie Hobeika for allegedly having the Saudi ambassador's helicopter fired on, Bashir Gemayel had about a hundred army officers abducted; they were traded for Hobeika three weeks later.

De Clerck and Malsagne date the start of the fighting between Kataeb and National Liberal Party militias to 12 May 1979, at Furn el-Chebbak; clashes recurred in various places until July 1980.

Dalida also sang at the new Summerland hotel in Jnah in September 1979 (de Clerck and Malsagne). The Kataeb-Tashnag clashes of 11 September belong to a series: Hanf records hostilities in May and September 1979, settled amicably; de Clerck and Malsagne date fighting to November; Traboulsi says that in 1978-1979 the Phalange and Chamoun's Tigers gradually subdued the Armenian militias, which would not pay them taxes.

De Clerck and Malsagne put October 1979 abductions in the North at 500 to 1,000 people.

Hanf: early in 1980 Amal fought the Iraqi-backed Arab Liberation Front in Beirut's suburbs while Fatah tried to mediate, as relations between Shi'is and Palestinians grew worse; the fighting later reached the south.
