De Clerck and Malsagne have Iranian clerics and activists settling in the Bekaa, and then in Tyre, from 1980, before 500 to 2,000 Revolutionary Guards entered Lebanon in June 1982.

De Clerck and Malsagne list Wadi Chahrour and Kfarchima among the National Liberals' bases in Beirut's south-eastern suburbs and end the wave of clashes between Christian militias on 2 July 1980. Ménargues describes near-daily fighting in the second half of June. Bashir Gemayel settled the rivalry by force on 7 July.

Ménargues lists the participants as Syrian foreign minister Abdel Halim Khaddam, the Arab League's representative and the Saudi and Kuwaiti ambassadors, Ali Chaër and Abdel Hamid Bouayajane. That day a general strike against the Syrian presence shut down the Christian regions.

Hanf describes the Shi'i Amal movement fighting the Iraqi-backed Arab Liberation Front and small communist organisations in West Beirut in the first months of 1982.

Abu Nidal's group, an enemy of the PLO leadership, had shot Shlomo Argov, Israel's ambassador in London, on the night of 3 June; Israel answered with the raids. Robert Fisk notes that the bombs hit a PLO arms dump in the old stadium near Fakhani and a Palestinian children's hospital by Sabra; Palestinian sources gave 50 dead, Lebanese officials 210 civilians. The original's 'Fakhani attack' is the Israeli raid of 17 July 1981.

Bashir Gemayel, back from Saudi Arabia on 2 July, said the PLO did not mean to leave. Two hours earlier, at the Alexandre Hotel, Sharon had told reporters, Robert Fisk among them, that Israel's only aim was to destroy the PLO and it wanted not 'one square inch' of Lebanon.

A US-backed Security Council resolution demanded that West Beirut's water and power be restored; Lebanon's minister of hydroelectric resources called the Israeli step 'inhuman'. Fisk dates the cut to early on 5 July, when Israel switched off electricity and water and barred food, having reduced power since the third week of June. Ménargues describes a further cut on 26 July.

US aircraft struck Syrian positions on 4 December. Fisk counts one plane brought down, with the pilot dead and the co-pilot taken prisoner (Jesse Jackson obtained his release in January 1984); Hanf counts two planes lost. Hanf also places, without a date, the deaths of eight Marines from Syrian artillery fire in the same episode.

On 29 January the Druze resumed attacking the army at Souk al-Gharb, after Shi'i militia sniping at the army and French troops from mid-January, Hanf's next escalation.

Counts of attacks on the Israeli army vary by source and period: Fisk reports 15 ambushes a week on average by February 1984 and a hundred attacks in December 1984; de Clerck and Malsagne put suicide attacks at about a hundred a month in 1984.

Hanf gives 3 July 1984 for the security plan's entry into force; this entry and entry 725 use 4 July. Hanf adds that the Green Line barricades were cleared at the end of July.

Annual figures: the pound fell to about 16 to the dollar in 1985 against 6.5 in 1984, with retail inflation of about 70 per cent (Hanf, citing Abou Rjaily and Labaki); de Clerck and Malsagne put the 1985 devaluation at 150 per cent. Hanf notes that rumours of large PLO deposits briefly strengthened the pound in early 1985.

Historians describe the collapse of real wages behind such decrees: against 1974, the statutory minimum wage kept 13 percent of its buying power at the end of 1986 (Hanf, after Abou Rjaily and Labaki).
