De Clerck and Malsagne and Tegho Bou Nassif date Zahleh's entry into the war to 24 August 1975, when Palestinian fighters planted a bomb in its tourist district, Wadi al-Arayish. In Hanf's account, Zahleh's Christians and Shi'is of its outskirts and nearby villages, helped by Palestinian guerrillas, came to blows late in August after a non-political arcade quarrel. Three Zahleh men were executed at the end of August.

Formed in September 1975 through Syria's foreign minister Abdel Halim Khaddam, the National Dialogue Committee of some twenty leaders debated secularism and ending sectarian quotas; Hanf says it broke up empty-handed.

Dates differ between historians: 16 January (Ménargues), 18 January (de Clerck and Malsagne; consistent with Fisk), 19 January (Hanf), 20 or 22 January (Traboulsi). Maslakh, next door, fell at the same time. Most of the district's people were Shi'is, living alongside Palestinians, Kurds and Armenian Lebanese. Haugbolle estimates 150-500 dead, de Clerck and Malsagne 600-1,000; some 30,000 people were driven out to West Beirut and the southern suburbs.

On 11 March Brigadier-General Aziz al-Ahdab, Beirut garrison commander (retired, says Traboulsi), seized the television station, named himself interim military governor and called for Frangieh's resignation and an early election. Few troops stood behind him and Syria opposed him: on 15 March PLA and Saiqa units under Syrian control blocked his men and Khatib's Lebanese Arab Army on their way to Baabda. Backed by Chamoun, Gemayel and President Assad, Frangieh refused to go.

Parliament used the truce to amend Article 73 of the constitution so that Frangieh's successor could be elected early: on 9 April according to Hanf, 10 April according to Yara El Khoury. The truce had coincided with the arrival on 31 March of the US envoy Dean Brown.

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.

De Clerck and Malsagne report that Eddé went into exile in Paris after surviving three attempts on his life, one of them outside his home.

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

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.

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 and Picard agree that Haddad declared his 'State of Free Lebanon' at Marjayoun on 18 April 1979, in reaction to the army being sent towards the UNIFIL area under the March 1979 defence law; de Clerck and Malsagne put its size at 250 square kilometres and call it entirely reliant on Israel. Hanf has Haddad's troops stopping the battalion; de Clerck and Malsagne and Picard, Israeli aircraft bombing it; Fisk, Israel letting its militia shell it. Traboulsi dates Haddad's break to his Army of Free Lebanon of June 1976, Ménargues to a secession at the end of 1977. Hanf adds that once Haddad had lost his rank and been dismissed in disgrace, Israel paid his men.

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.
