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 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 start of Operation Litani to 14 March (de Clerck and Malsagne, Traboulsi, Quéméner; de Clerck's chronology gives 15 March) and its end to 21 March. Up to 25,000 Israeli soldiers and 120 tanks took part (de Clerck and Malsagne). Estimates of the dead range from about 300 Palestinian fighters (de Clerck and Malsagne) to about 2,000 people, mostly civilians (Fisk; de Clerck and Malsagne; Picard). Estimates of the displaced range from 150,000 (Hanf's refugee table) and more than 200,000 (de Clerck and Malsagne, Picard) to 285,000 (Lebanese government figure cited by Fisk). On 15 March Israeli aircraft bombed the Palestinian camps of Beirut, Tyre and Damour.

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.

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.

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.

The invasion, called 'Operation Peace for Galilee', began on Sunday 6 June: Israeli commandos crossed the border at 1.30 a.m. to attack Beaufort castle (Ménargues), and up to 25,000 troops moved along the coast, through Tibnin and across the eastern sector (Fisk). The government declared a limited aim of a 40-kilometre zone, but Defence Minister Ariel Sharon and Chief of Staff Rafael Eitan kept advancing (Hanf). One overview in de Clerck and Malsagne and Picard's chronology give 5 June.

In rue Aussi near Sanayeh park a car bomb exploded among rescuers minutes after Israeli bombs levelled two five-storey blocks, says Robert Fisk's dispatch datelined West Beirut, 5 August; a neighbour put over 100 people, mostly squatters from the camps and the south, beneath the rubble. Arafat had reportedly met there just before.

Bashir Gemayel was killed at about 4 p.m. during his weekly visit to the Kataeb office in Ashrafieh, nine days before taking office. The bomb, about 35 kilos of explosive, had been placed two days earlier in the flat above by Habib Tanios Chartouni, a member of the Syrian Social Nationalist Party, arrested on 16 September (Ménargues). Prime Minister Wazzan announced the death at midnight. Hanf counts 26 dead.

Robert Fisk recounts that Defence Secretary Weinberger proposed an award for Charles Johnson, a Marine captain who in January 1983 stopped an Israeli tank unit entering the Marine sector off the old Sidon road by climbing onto the lead tank and pointing his pistol at its commander.

Early in 1983 the Eighth Brigade went into all of Beirut, the east included, under a plan to collect light arms in the city and clear heavy weapons and gunmen from Greater Beirut. The Lebanese Forces resisted, then on 1 March 1983 agreed to return East Beirut and the port's fifth basin to the state.

De Clerck and Malsagne say the deputies were told of the text at a closed session on 15 May; Prime Minister Wazzan approved it and sent it to the president, and that month 70 of the 91 deputies still in office backed the government.

Counts differ: Hanf has 64 for, 2 against and 4 abstentions among 70 deputies present (40 of 50 Christian and 24 of 41 Muslim members in favour); Traboulsi has 65 for, 2 against and 4 abstentions; Fisk puts the vote on 15 June. Traboulsi says the government formally renounced the agreement on 5 March 1984, Amine Gemayel never having signed it.

The fighting set Fatah dissidents under Abu Musa, Syrian artillery and pro-Syrian Lebanese parties against Arafat's loyalists and the Sunni Tawhid militia. Hanf writes that in early November it took on the character of a Sunni-Alawite civil war, and that Tawhid fighters killed hundreds of communists.

The New Jersey fired shells, not bombs: one-ton 16-inch rounds, according to Fisk. De Clerck and Malsagne say its rounds often missed, by up to 9,000 metres, and killed civilians; Christians called it 'New Jersa', a new shame.

The books describe a joint Amal and PSP (Druze) offensive, not Amal alone; the mainly Shi'i Sixth Brigade went over to Amal. Hanf dates the last Christian soldiers' withdrawal to the east, and so the completed division, to 7 February. De Clerck and Malsagne record the uprising's name, 'the 6 February movement'. About 50,000 Christians moved east, almost half the public radio's 400 staff left their posts, and Télé-Liban split. A later Sunni militia took its name from the date (Hanf).

De Clerck and Malsagne give 14 February 1984 for the PSP's capture of the Chahhar district, part of a week-long uprising in Beirut and the mountain.
