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.

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.

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.

Traboulsi, de Clerck and Malsagne, and Yara El Khoury date the Syrian-mediated cease-fire to 23 January. PLA and Saiqa units attacked Zgharta in the north but were repulsed, and Zahleh, besieged, held out.

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.

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).

Hanf notes that in December 1977 Menachem Begin, Israel's prime minister, had excluded any return of the Palestinian refugees in neighbouring countries.

Fisk dates the arrival in Tyre of UNIFIL's first unit, Colonel Jean Germain Salvan's French paratroopers, to 23 March. That morning, at the nearby Hassan Borro barracks, Palestinians and Lebanese officers nearly opened fire over the handover.

According to de Clerck and Malsagne, a Mossad agent detonated a bomb in a Volkswagen as Salameh's Chevrolet passed. His wife, Georgina Rizk, had been Lebanon's first Miss Universe.

Hanf writes that West Beirut's Sunnis sided with the Shi'is on National Day, which became a protest against every foreign armed presence; cedar flags hung all over the city.

Hanf places it in early 1980. Palestine Liberation Army units under Syrian or pro-Syrian command took over the Syrian posts in and near Beirut, while the Syrian troops, bar one garrison, quit the city's dividing line and the coast road to the south and redeployed to the heights above the capital.

Hanf: clashes among the Christian militias grew more frequent after the partial Syrian withdrawal, which removed Syrian checkpoints on the roads into East Beirut and between Achrafieh and the Christian suburbs and gave the militias one unbroken territory for the first time since 1976.

Ménargues dates the resignation to March 1980, after repeated deadlock between Hoss and Sarkis over the army; Hoss stayed on as caretaker until Shafiq Wazzan's appointment in late October.

In Ménargues's account the appointment came on 25 October, after Damascus had vetoed Takieddine Solh and put up three candidates including Hoss; by picking none of them Sarkis disregarded Syrian advice for the first time in his presidency.

According to Ménargues, Bashir Gemayel answered the collapse of a cease-fire on 22 April, which left 140 dead or wounded in Beirut within hours, by having the international airport shelled. On 11 May US ambassador John Gunther Dean urged the Lebanese Forces, via Alfred Madi, to let it reopen; that evening they dropped their objection.
