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.

Sudan supplied the Arab peace force's first contingent, some 2,000 men, and Libya the next (Hanf).

Yara El Khoury dates the start of the final offensive on Jisr al-Basha and Tal al-Za'tar to 22 June 1976, and Hanf's account (Jisr al-Basha stormed eight days after the first assault, on 1 July) points to the same week. The camps had been blockaded since January. Hanf says Chamoun's Tigers and Christian units of the army led the attack, the Kataeb joining later; a joint command of Bashir Gemayel (Kataeb), Dany Chamoun and Nabil Karam (NLP), Fawzi Mahfouz (Tanzim) and Etienne Saqr (Guardians of the Cedar) coordinated it (de Clerck and Malsagne).

Historians disagree on 1976: Haugbolle ranks it among the war's largest emigration waves, while de Clerck and Malsagne see many returning that year after nearly 400,000 Lebanese had left by 1975. Haugbolle notes that no official figures exist.

Ménargues dates the formal unification of the Christian militias under Bashir Gemayel's command to 31 August 1976; Yara El Khoury has it announced to President Frangieh in early September 1976. According to de Clerck and Malsagne, 'Lebanese Forces' was not the official name until 1981, but the unified command was officially founded on 25 March 1976.

Syrian helicopters and armoured limousines carried the 67 deputies to the Park Hotel in Chtaura, in the Syrian-held Bekaa, where 2,000 Syrian soldiers and 40 tanks guarded the ceremony (Fisk). Sarkis used his address to declare that Lebanon itself had invited the Syrian army in (Hanf).

From Sarkis's inauguration on 23 September Hanf counts three quiet days, the Semiramis Hotel attack in Damascus and a Syrian move two days after it, placing this offensive at about 28 September. The Palestinian and leftist forces lost the Upper Metn; Traboulsi notes that the Joint Forces' largest concentration, there under Abu Khalid al-Amleh, never engaged the advancing Syrians.

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.

Under the Riyadh decisions of October 1976 all parties were to give up heavy weapons to the Arab Deterrent Force; the Hoss government set a 5 December 1976 deadline (Traboulsi). Fisk reports the militias did not hand them in; Hanf, that the Palestinians moved most of theirs south of the 'red line'.

De Clerck and Malsagne put the Lebanese Front's seminar at the Sayyidat al-Bir convent, not Broumana, on 21 January 1977. Its leaders, they report, judged the independence-era institutions obsolete, raised partition and defined a 'plurality of civilisational groups'. The body was the Lebanese Front, the Christian leaders' coalition, not the Lebanese Forces militia.

Its unprecedented powers spanned planning, funding and running reconstruction. It replaced the Planning Ministry in 1977; Picard calls it the economy's 'superministry'.

Jumblatt was ambushed near a Syrian checkpoint of the Arab Deterrent Force; Fisk places it on the mountain road near Baaqlin. Most historians give 16 March 1977 (Traboulsi, de Clerck and Malsagne, the Confluences authors, and Hanf on one page); Hanf elsewhere and Ménargues give 17 March, which Ménargues ties to the burial. His son Walid took over, and Christians were killed in reprisal in Chouf villages. Hanf writes that most politicians, Muslims above all, took the murder as a warning against defying Syria openly, and that Jumblatt had attacked the Syrian presence in speech and print, in Lebanon and abroad.

The force is usually called the Arab Deterrent Force (ADF) in English.

The bombing came the evening the government chose a new army commander, a change arranged by Boutros, who held foreign affairs and defence, and regarded by the Christian parties as cause for war.

Muslim leaders accused Hanna Saïd, commander since September 1975, of leniency towards the Lebanese Front (Traboulsi: of closeness to the dissident troops in the south). His replacement, Victor Khoury, a Constitutional Bloc sympathiser committed to Christian-Muslim coexistence, ran the army and its rebuilding from March 1977 to December 1982.

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.

Hanf notes that in December 1977 Menachem Begin, Israel's prime minister, had excluded any return of the Palestinian refugees in neighbouring countries.
