January 1975 saw heavy Israeli attacks on the South. Israeli forces razed Kfar Chouba, a border village, about a week after 7 January (Hanf), and Palestinian commandos shelled army positions in Tyre during border clashes with the Lebanese army (de Clerck and Malsagne). The figures for 3 January come from contemporary press reports.

Antoine Khuraych headed the Maronite Church from his election on 3 February 1975 (enthronement 9 February) until 1986, styling himself the 'patriarch of dialogue'.

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.

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.

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.

Talks in France with the government and Mitterrand's opposition left Jumblatt sure that France could do nothing in Lebanon against Syrian and US opposition (Traboulsi). His tour, by boat from encircled West Beirut to Cyprus, then Cairo, Algiers and Paris, sought Arab contingents to offset the Syrians.

Vance's airport motorcade skirted Sabra and Chatila after a Beirut visit, dated by Fisk to autumn 1977, to hear the government's views on the Palestinians' future.

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

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.

Historians describe the Syrian pull-back from Beirut in 1980 as a redeployment to the Bekaa and to mountain positions overlooking the capital, with a garrison kept in West Beirut (Hanf). The Lebanese army could not replace the departing Arab Deterrent Force everywhere (Picard).

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.

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.

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.
