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 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.

Hanf and Ménargues count 66 votes for Sarkis out of 69 cast; de Clerck and Malsagne give 70. National Movement and PLO mortars fired as deputies, escorted by Saiqa, PLA or Syrian troops, met at the Villa Mansour on the demarcation line. Votes were reportedly bought, by Syria (de Clerck and Malsagne) or with Saudi and CIA money (Traboulsi). Sarkis was sworn in only on 23 September.

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.

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.

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).

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.

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.

De Clerck and Malsagne date the end of the shelling to 7 October. On that day President Sarkis asked in public for the Arab Deterrent Force's mandate, due to lapse on 28 October, to be extended, and Syria maintained its blockade until the renewal.

Ménargues writes that when the Moukafaha, Johnny Abdo's own intervention unit, arrested Elie Hobeika for allegedly having the Saudi ambassador's helicopter fired on, Bashir Gemayel had about a hundred army officers abducted; they were traded for Hobeika three weeks later.
