Israel, Hanf notes, would accept no Arab troops south of the 'red line', Syrian ones least of all. When a Syrian unit entered Nabatiyeh in January 1977, an Israeli protest got it withdrawn and the Palestinians kept the town.

Its members were technocrats and businessmen; the one politician, Fouad Boutros, held both foreign affairs and defence (Traboulsi). Early on, at Syria's behest, it brought in press censorship (Hanf, Fisk); Traboulsi also mentions an order for militias to surrender their arms.

Sami al-Khatib took over the ADF from Ahmad al-Hajj, who never won Syria's trust, and led it until 1983.

Robert Fisk, who reported from the area, saw Israeli tanks on Lebanese soil near Ibl al-Saqi and Israeli shelling of Christian villages such as Rachaya al-Fukhar, where Palestinian guerrillas had dug in.

Israel's Christian allies emerged with a slightly wider strip, spanning nearly the whole frontier from sea to Hermon; Fisk dates the tank withdrawal to 26 September.

By now Syria was fighting on the Palestinians' side. Hanf says the clashes ended once the Arab Deterrent Force's Saudi and Sudanese contingents deployed between Chiyah and Ain el-Remmaneh.

Neither parliament nor president could enforce the resolution, Hanf notes. The 74 deputies in attendance passed it without dissent: it reserved arms to the legitimate Lebanese forces, told the Palestinians and 'other parties' to end armed action, and applied Lebanese law to all on Lebanese soil.

Colonel Jean Germain Salvan was badly hurt in both legs in early May, Fisk writes, when dissident PLO gunmen fired on the Fatah jeep carrying him, killing a French soldier and his Palestinian driver; Arafat called it a crime. Hanf adds that such losses made the French unit much more careful.

De Clerck and Malsagne record that Frangieh had quit the Lebanese Front the day before over its ties with Israel. The reconciliation, Hanf notes, made the north a pro-Syrian bloc.

Musa al-Sadr travelled to Libya on 25 August (de Clerck and Malsagne) at the invitation of the Libyan government (Ménargues) and was never seen again; Hanf dates the disappearance to September. Beirut papers speculated about the Shah's secret police or Libyan intelligence. Fisk writes that he was almost certainly killed in Libya. The loss mobilised the Shi'a and later strengthened Amal.

Schools, hospitals and factories were destroyed in the new bombardment, and Lebanese gendarmes logged 2,000 impacts a day in Achrafieh. Hanf links it to the Camp David agreement reached a few days before.

In February 1978 Achkar had led the Lebanese soldiers in the clash with Syrian troops at Fayadiyeh; in October he left the army with about twenty men and founded a 'Revolutionary Lebanese Army Movement'. Boutros was due to fly with the president to the Arab summit in Baghdad when the Lebanese Forces, avenging Achkar, ambushed him on the way to the airport. Lieutenant Qozhaya Chamoun, who led the convoy, was abducted and later murdered; Boutros himself got away.
