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.

Fisk reads the mutilation of al-Lawzi's body as a warning to the Lebanese press: the flesh of his writing hand had been removed, by knife or acid, and two shots fired into his neck from behind. A shepherd found him, half under snow, in the Aramoun woods on 5 March.

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.

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.

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.

On 4 March 1985, a day after an Israeli raid, a bomb on the roof of the resistance office above Maarakeh's mosque killed Khalil Jerardi, nominally Amal but a Hezbollah supporter, and Mohammed Saad, an Amal commander in the south. French UN officers who examined it believed the departing Israelis had left it (Fisk's report, not an established finding).

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).

The books place the renewed Amal-Hezbollah fighting of December 1989 in Iqlim al-Touffah, east of Sidon. Hanf says it started after Hezbollah fighters from the Bekaa crossed the zone held by the South Lebanon Army.

De Clerck and Malsagne date Sfeir's threat to late April or early May 1990: Christian soldiers in Aoun's army faced excommunication, and their dead the denial of Christian burial. They list it among the pressures that halted the army's advance on the Lebanese Forces headquarters at Karantina. The original speaks of a reiterated threat.
