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'.

Hanf: Dany Chamoun left politics, but his father Camille, badly shaken by the loss of his party's militia, put the Lebanese Front's political unity first and remained its chairman.

In Ménargues's account Damascus rejected Takieddine Solh, finding him too lukewarm about Lebanese–Syrian friendship, and offered three names instead, Selim Hoss's among them.

Syrian troops guarded Riad Taha's and al-Lawzi's funerals, Fisk notes; the government condemned both killings but claimed not to know the culprits. Fisk counts both among journalists who crossed Syria.

Dates differ. De Clerck and Malsagne's chronology has the Lebanese Forces controlling East Beirut from 31 October 1980. Ménargues puts the LF's 48-hour assault on Ain al-Remmaneh, held by Elias Hannouche's Chamounists, ten days after the 10 November car bombs, around 20 November 1980.

After the December 1980 clashes in Zahleh, Syrian troops gave up their checkpoints inside the town but kept it under blockade (Hanf). Ménargues, however, says ADF checkpoints were still on the town's main roads when Lebanese Forces fighters seized them in the first days of April 1981.
