Hanf writes that Major Haddad's forces fired at Kaukaba on the units sent south in early August, men of the 'vanguard' Syria trusted, and drove them into retreat. Haddad later rebelled openly against the army command, and Israel took over paying his men.

Ménargues writes that when the Moukafaha, Johnny Abdo's own intervention unit, arrested Elie Hobeika for allegedly having the Saudi ambassador's helicopter fired on, Bashir Gemayel had about a hundred army officers abducted; they were traded for Hobeika three weeks later.

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.

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.

De Clerck and Malsagne list Wadi Chahrour and Kfarchima among the National Liberals' bases in Beirut's south-eastern suburbs and end the wave of clashes between Christian militias on 2 July 1980. Ménargues describes near-daily fighting in the second half of June. Bashir Gemayel settled the rivalry by force on 7 July.

Historians date the assault to 7 July 1980 (Ménargues, de Clerck and Malsagne, Hanf, Traboulsi, Picard). At dawn Bashir Gemayel's units struck National Liberal offices and barracks throughout the Christian region, the Safra Marine resort north of Jounieh among them, under strict orders to spare Camille and Dany Chamoun and their families. That evening he proposed merging the militias into the Lebanese Forces under his command; Dany Chamoun left for exile the next day. Estimates of the dead range from about 70 (Ménargues) to 150-200, mostly civilians (Traboulsi; de Clerck and Malsagne give about 150, including 83 Tigers). Ménargues says Bashir code-named the operation 'Altalena'.
