From Sarkis's inauguration on 23 September Hanf counts three quiet days, the Semiramis Hotel attack in Damascus and a Syrian move two days after it, placing this offensive at about 28 September. The Palestinian and leftist forces lost the Upper Metn; Traboulsi notes that the Joint Forces' largest concentration, there under Abu Khalid al-Amleh, never engaged the advancing Syrians.

APUR, the Atelier parisien d'urbanisme, drew up this 1977 plan, the earliest of three reconstruction studies made during the war.

Muslim leaders accused Hanna Saïd, commander since September 1975, of leniency towards the Lebanese Front (Traboulsi: of closeness to the dissident troops in the south). His replacement, Victor Khoury, a Constitutional Bloc sympathiser committed to Christian-Muslim coexistence, ran the army and its rebuilding from March 1977 to December 1982.

The Qaa massacre is dated to the night of 27-28 June (de Clerck and Malsagne) or to 29 June (Hanf); Ras Baalbek and Jdeidet al-Fakiha were also raided. De Clerck and Malsagne blame Syrians in civilian clothes, carrying name lists and guided by local Christian members of the SSNP and the Communist Party, and see the killings as revenge for Ehden. Hanf counts 26 dead, de Clerck and Malsagne 32 to 36. The community's Supreme Council asked that a day of national mourning be held.

The Saudis announced their departure in March 1979 (Ménargues). Picard has Syria's partners, among them Saudis, Sudanese and Emiratis, leaving two years after the 1976 summits; de Clerck and Malsagne call the ADF wholly Syrian from 1979.

Ménargues has two Syrian helicopters downed: a Mi-8 supply craft, hit by F-15s around noon just after leaving Rayak, and a French-built Alouette late in the day; in between, jets struck ADF positions around Sannine. Israel acted at Christian leaders' request once Syria held Sannine's summit; next day Syria answered with surface-to-air missiles in the Bekaa.

Fisk dates the PLO's statement that it would leave Beirut, made public by Saeb Salam, to 30 June; Hanf puts its agreement in principle only at the end of July. On 27 June an Israeli cabinet statement had first floated a negotiated exit: the Lebanese army would take over West Beirut and the disarmed fighters would leave by road for Syria (Ménargues).

Two US Marines were killed and 14 wounded on 29 August, as Amal, Murabitun and PSP fighters, having seized the south-western suburbs, stormed West Beirut and Syrian-held batteries shelled the east. Using tanks, the army had regained the city centre by 31 August, though not the suburbs.

Signed in Damascus by Elie Hobeika (Lebanese Forces), Nabih Berri (Amal) and Walid Jumblatt (PSP) under Syrian sponsorship. It provided for Christian-Muslim parity during a transition towards the end of political sectarianism, a stronger prime minister and cabinet, a senate, and 'strategic complementarity' with Syria. It did not end the war: President Gemayel refused it and, in January 1986, Samir Geagea's forces drove Hobeika out of East Beirut. Its provisions were largely taken up in the Taif Agreement of 1989.

Traboulsi dates the break between the two presidents to their meeting of 13-14 January 1986, when Gemayel rejected the Syrian-sponsored Tripartite Accord.

Hanf writes that in June 1987 Walid Jumblatt was forced to surrender to Syria several men of the PSP intelligence branch, his security chief among them, who had joined in hit-and-run attacks on Syrian forces in West Beirut.
