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.

Hanf writes that West Beirut's Sunnis sided with the Shi'is on National Day, which became a protest against every foreign armed presence; cedar flags hung all over the city.

The Arab summit met in Tunis from 20 to 22 November 1979.

Fisk: violating the UN's agreements with Israel, Haddad's militia set up positions inside the UNIFIL zone in spring 1980, beside At-Tiri, near Beit Yahoun and at ruined Rashaf, where it parked a Sherman tank reached by a road built with Israeli help.

Fisk: in the April 1980 fighting at At-Tiri, Haddad's gunmen killed Private Stephen Griffin of the Irish UNIFIL battalion and UN troops killed a militiaman, whose death two other Irish soldiers later paid for. The militia also held the coastal strip between the French unit and Naqoura and shot at helicopters.

Hanf sees the Iran–Iraq war of September 1980 as already being fought earlier in Beirut's suburbs: Amal and the Iraqi-backed Arab Liberation Front clashed there despite repeated ceasefires, and the fighting spread south, where a dozen villages were contested until mid-1982. De Clerck and Malsagne list the Iraqi Baath among Amal's adversaries.

Hanf records the Lebanese Front's formula as 'political pluralism, military unity'. Traboulsi describes an eight-member executive committee under Bashir Gemayel running the Lebanese Forces: three Phalange seats, two each for the National Liberals and the Tanzim, one for the Guardians of the Cedars. Ménargues notes that after Ain el-Remmaneh Bashir had every unit swap its militia badges for one common insignia.

Ménargues counts 10 dead and 62 wounded from two car bombs in Achrafieh, Bashir Gemayel's power base.

Historians date the battle of Zahleh from this day, when Lebanese Forces fighters beat off a Syrian attack on the town and a siege of some 90 days began. Ménargues says Syrian heavy guns killed 50 and wounded over 200 that day in Zahleh and the Christian zone north of Beirut.

Ménargues dates a day of intensive shelling of Zahleh, with about twenty dead, to 6 April.

Ménargues writes that Syrian special forces, landed by helicopter at dawn on 10 April, soon took the heights of Qalaat Aramta and Deir Charfé around Zahleh, leaving its defenders almost encircled.

According to Ménargues, Bashir Gemayel answered the collapse of a cease-fire on 22 April, which left 140 dead or wounded in Beirut within hours, by having the international airport shelled. On 11 May US ambassador John Gunther Dean urged the Lebanese Forces, via Alfred Madi, to let it reopen; that evening they dropped their objection.
