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.

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.

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.

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.

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.

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.

Ménargues dates the bombing to 16 December. The six-storey embassy at Ramlet al-Baida was destroyed by an explosives-laden car driven by Shiite suicide attackers; a group nobody knew claimed it, and the ambassador's body took four days to find. It followed heavy fighting in West Beirut on 4 December between Amal and pro-Iraqi Baathists, and a Lebanese Forces visit to Baghdad.

The victims were Guy Cavallo, the French military attaché's cipher clerk, and his wife, murdered at their West Beirut home.

In Ménargues's account of the Bikfaya funeral, Bashir's coffin was carried from the church of Mar Abda onto a gun carriage before the entire government, the diplomatic corps and every deputy, even those who had boycotted his election. Israeli troops had entered West Beirut at 5 a.m. that day, breaching the agreement negotiated by Philip Habib.

On 15 December, after 102 days, the siege of Deir el-Qamar ended. Israel brokered the departure of Samir Geagea's Lebanese Forces and most refugees for East Beirut; the town was left mainly to its elderly.

Hanf counts some 15,000 Christian civilians leaving the coastal Chouf for Israeli-occupied territory; Mechref is not named.
