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.

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.

Hanf has the Syrian army moving again only once Tal al-Za'tar had fallen, increasing pressure on the encircled Palestinian and leftist forces in the Upper Metn; these were expelled at the end of September.

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.

Ratified by an Arab summit in Cairo on 25 October, the Riyadh decisions required all parties to surrender heavy weapons and the Palestinians to return to the zones granted by the 1969 Cairo Agreement, and created a 30,000-man Arab Deterrent Force under President Sarkis, its largest contingent by far, 25,000-27,000 men, being the Syrian troops already in Lebanon. Saudi Arabia had sent the invitations on 15 October; the leaders of Saudi Arabia, Kuwait, Egypt, Syria and Lebanon met the PLO chairman in Riyadh on 16, 17 or 18 October, depending on the historian. The cease-fire's start is dated 16 October (Hanf), 21 October (Traboulsi) or 15 November (de Clerck and Malsagne).

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).

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.

Hanf writes that the Lebanese Front was left with an enclave of roughly a tenth of Lebanon once Syrian troops had moved into the northern Christian mountains, Koura, Batroun and the coast as far as the Madfoun bridge. Frangieh gave Kataeb members in the north until the month's end to give up their weapons and quit the party, or else leave.

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.

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.
