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.

De Clerck and Malsagne and Tegho Bou Nassif date Zahleh's entry into the war to 24 August 1975, when Palestinian fighters planted a bomb in its tourist district, Wadi al-Arayish. In Hanf's account, Zahleh's Christians and Shi'is of its outskirts and nearby villages, helped by Palestinian guerrillas, came to blows late in August after a non-political arcade quarrel. Three Zahleh men were executed at the end of August.

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.

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.

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.

Syria, Hanf writes, had lost interest in disarming the Palestinians by autumn 1977, with Sadat's initiative under way, and the deal soon counted for nothing. It had bound the PLO to keep out of a ten-kilometre belt beside the Israeli frontier and, chiefly, to halt raids and shelling across it.

Israel's Christian allies emerged with a slightly wider strip, spanning nearly the whole frontier from sea to Hermon; Fisk dates the tank withdrawal to 26 September.

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.

One of many clashes between Kataeb and National Liberal militiamen: de Clerck and Malsagne count 46, with 200 dead, from 1976 to 1980, the latest wave running from 12 May 1979 to 2 July 1980 and reaching Achrafieh early in 1980. Ménargues traces the tension of early 1980 partly to disputes over dividing the arms Israel supplied.

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.

De Clerck and Malsagne, drawing on Ronen Bergman, attribute to Ariel Sharon a series of car bombings from October 1981, carried out under the name 'Front for the Liberation of Lebanon from Foreigners' and aimed chiefly at Palestinians, to provoke retaliation that could justify an invasion. They list no individual attacks, so this bombing cannot be matched to their account.
