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.

The meeting was called after Begin told the Knesset on 4 June of his promises to Lebanon's Christians. The Arab envoys asked Bashir Gemayel to break with Israel; he demanded guarantees in return (Hanf, Ménargues).

Ménargues has some 600 Internal Security Forces gendarmes entering Zahleh on 30 June, ending the siege, and the 95 fighters from outside the town leaving by bus over a mountain road behind a Syrian colonel's car, past Syrian troops posted along it; Hanf says they left under Saudi escort. Siege toll: 200 dead and over 2,000 wounded (Ménargues), over 200 and 2,000 (de Clerck and Malsagne), 300 and 3,000 by the Phalange's count (Fisk).

Ménargues lists the participants as Syrian foreign minister Abdel Halim Khaddam, the Arab League's representative and the Saudi and Kuwaiti ambassadors, Ali Chaër and Abdel Hamid Bouayajane. That day a general strike against the Syrian presence shut down the Christian regions.

Bashir Gemayel's pledge took the form of a letter to President Sarkis dated 6 July, which Sarkis never published (Ménargues).

Ménargues counts 6 dead and 20 wounded in the two raids, on Democratic Front sites at Habbouch (near Nabatiyeh) and Ghaziyeh (near Sidon). Hanf dates the Israel–PLO 'Fourteen Day War' from them.

Ménargues counts six bridges over the Awali and Litani destroyed in the raids. The Palestinians replied the same day with some 2,000 shells and rockets on Nahariya and Kiryat Shmona.

The raid targeted PLO offices in the Fakhani district of West Beirut. Tolls differ: Ménargues gives 191 dead and over 730 wounded; Fisk and Picard about 300 dead; Hanf hundreds killed and over a thousand hurt, chiefly civilians.

Ménargues dates to 22 July Reagan's indefinite freeze on F-16 deliveries to Israel and a unanimous Security Council call for an immediate cease-fire, which Arafat accepted at once.

The cease-fire came from separate talks with Israel and the PLO, helped by Saudi diplomats (Hanf), with the UN relaying to the PLO (Ménargues, Fisk). Border fire was to stop; Syria could keep its Bekaa missiles unused, and Israeli overflights continued. In Ménargues's account a last Israeli demand held up Israel's public acceptance for two days.

In Ménargues's account the Saudi and Kuwaiti foreign ministers proposed Syria–Lebanese Forces talks after seeing Khaddam in Beirut on 3 September. Next day at Baabda, Bashir Gemayel accepted the opening of crossing points. The Vigilance Committee's evening statement reserved arms imports to legal forces and set up a body to police the coast and ports; Bashir and the Lebanese Front rejected it.
