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.

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.

Tal al-Za'tar fell on 12 August 1976 (13 August in Ménargues) after more than 70 assaults. Ménargues and Hanf count a siege of 52-53 days from the final offensive; de Clerck and Malsagne and Traboulsi count six months from the January blockade. An ICRC report cited by de Clerck and Malsagne puts the dead at about 2,500 residents and defenders and up to 800 attackers; many died trying to escape. The Tigers and the Guardians of the Cedar led the last assault, reportedly with Syrian and Israeli officers present. The camp was bulldozed and never rebuilt.

Under the Riyadh decisions of October 1976 all parties were to give up heavy weapons to the Arab Deterrent Force; the Hoss government set a 5 December 1976 deadline (Traboulsi). Fisk reports the militias did not hand them in; Hanf, that the Palestinians moved most of theirs south of the 'red line'.

De Clerck and Malsagne record that Frangieh had quit the Lebanese Front the day before over its ties with Israel. The reconciliation, Hanf notes, made the north a pro-Syrian bloc.

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.

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.

Fisk: in the April 1980 fighting at At-Tiri, Haddad's gunmen killed Private Stephen Griffin of the Irish UNIFIL battalion and UN troops killed a militiaman, whose death two other Irish soldiers later paid for. The militia also held the coastal strip between the French unit and Naqoura and shot at helicopters.

Ménargues writes that Syrian special forces, landed by helicopter at dawn on 10 April, soon took the heights of Qalaat Aramta and Deir Charfé around Zahleh, leaving its defenders almost encircled.

Ménargues's run of drone losses begins on 14 May, when a Syrian SAM-6 downed an Israeli reconnaissance drone over the Bekaa; more were lost on 19, 22 (two) and 25 May.
