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.

Dates differ between historians: 16 January (Ménargues), 18 January (de Clerck and Malsagne; consistent with Fisk), 19 January (Hanf), 20 or 22 January (Traboulsi). Maslakh, next door, fell at the same time. Most of the district's people were Shi'is, living alongside Palestinians, Kurds and Armenian Lebanese. Haugbolle estimates 150-500 dead, de Clerck and Malsagne 600-1,000; some 30,000 people were driven out to West Beirut and the southern suburbs.

Barely a tenth of American and British residents accepted the evacuation, Fisk writes. The British went by road, the PLO escorting them through West Beirut and a Libyan officer on to the Syrian lines; a day later a US landing craft took evacuees off from a PLO-guarded bathing club on the Corniche.

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.

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.

De Clerck and Malsagne and Picard agree that Haddad declared his 'State of Free Lebanon' at Marjayoun on 18 April 1979, in reaction to the army being sent towards the UNIFIL area under the March 1979 defence law; de Clerck and Malsagne put its size at 250 square kilometres and call it entirely reliant on Israel. Hanf has Haddad's troops stopping the battalion; de Clerck and Malsagne and Picard, Israeli aircraft bombing it; Fisk, Israel letting its militia shell it. Traboulsi dates Haddad's break to his Army of Free Lebanon of June 1976, Ménargues to a secession at the end of 1977. Hanf adds that once Haddad had lost his rank and been dismissed in disgrace, Israel paid his men.

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.

De Clerck and Malsagne, drawing on Ronen Bergman, attribute to Ariel Sharon a series of car bombings from October 1981, carried out under the name 'Front for the Liberation of Lebanon from Foreigners' and aimed chiefly at Palestinians, to provoke retaliation that could justify an invasion. They list no individual attacks, so this bombing cannot be matched to their account.

On 13 June Israeli forces reached Baabda and Yarze, seats of the presidency and the army command, and joined the Lebanese Forces' lines (Hanf, Ménargues); Fisk dates the arrival of Sharon and his forward troops at Baabda to just before midnight.

The massacre lasted from the evening of Thursday 16 September to the morning of Saturday 18 September (Traboulsi gives 15-17, Hanf 17-18). The killers were militiamen of the Lebanese Forces' security service under Elie Hobeika, together with men of Saad Haddad's South Lebanon militia. The Israeli army, which controlled the area after entering West Beirut on 15 September, let them into the camps, lit the camps with flares at night and watched from command posts nearby. Israel's Kahan Commission, published on 7 February 1983, held the Phalangists directly responsible and found Defence Minister Ariel Sharon personally responsible, recommending his removal; it also attributed indirect responsibility to other Israeli political and military leaders. Estimates of the dead range from about 460-800 to 3,500; Bayan Nuwayhed al-Hout's survey found victims of twelve nationalities, about half Palestinian and more than a quarter Lebanese.

After the Israeli advance, Lebanese Forces militiamen set up checkpoints in the Chouf and Aley; clashes with Druze fighters followed and the Israelis often mediated (Hanf). De Clerck and Malsagne date the 'Mountain War' from summer 1982, the Lebanese Forces fighting first the SSNP's Druze and then the PSP.

Lebanese and Israeli delegates met in turn at Khalde, in a repaired beach hotel, and at Kiryat Shmona. De Clerck and Malsagne count 37 meetings over 138 days, from December 1982 to May 1983.
