Hanf has the Syrian army moving again only once Tal al-Za'tar had fallen, increasing pressure on the encircled Palestinian and leftist forces in the Upper Metn; these were expelled at the end of September.

Ratified by an Arab summit in Cairo on 25 October, the Riyadh decisions required all parties to surrender heavy weapons and the Palestinians to return to the zones granted by the 1969 Cairo Agreement, and created a 30,000-man Arab Deterrent Force under President Sarkis, its largest contingent by far, 25,000-27,000 men, being the Syrian troops already in Lebanon. Saudi Arabia had sent the invitations on 15 October; the leaders of Saudi Arabia, Kuwait, Egypt, Syria and Lebanon met the PLO chairman in Riyadh on 16, 17 or 18 October, depending on the historian. The cease-fire's start is dated 16 October (Hanf), 21 October (Traboulsi) or 15 November (de Clerck and Malsagne).

Hanf writes that the Lebanese Front was left with an enclave of roughly a tenth of Lebanon once Syrian troops had moved into the northern Christian mountains, Koura, Batroun and the coast as far as the Madfoun bridge. Frangieh gave Kataeb members in the north until the month's end to give up their weapons and quit the party, or else leave.

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.

De Clerck and Malsagne date Lebanese Forces control of East Beirut to this day; Ménargues dates the final takeover of Ain el-Remmaneh to late November. See the note on 27 October.

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.

About 300 people died in bombings from 17 September to 2 October 1981, which de Clerck and Malsagne, citing Israeli journalist Ronen Bergman, put down to the 'Front for the Liberation of Lebanon from Foreigners', formed by Israeli officers against the Palestinians and their allies.

Hanf sets this fighting in a contest for Tripoli: with the local Sunni militia on their side, the Palestinians resisted Syria's bid to dominate the north.

De Clerck and Malsagne, drawing on Ronen Bergman, attribute to Ariel Sharon a series of car bombings from October 1981, carried out under the name 'Front for the Liberation of Lebanon from Foreigners' and aimed chiefly at Palestinians, to provoke retaliation that could justify an invasion. They list no individual attacks, so this bombing cannot be matched to their account.

Jawad Boulos was one of three 'wise men' in the leadership of the Christian Lebanese Front, with Fouad Ephrem Boustani and Charles Malek (Hanf).

On 17 May Antoine Fattal (Lebanon), David Kimche (Israel) and Morris Draper (US) signed in Arabic, French, English and Hebrew. The accord ended the state of war and made the south a security zone under joint supervision teams and a territorial brigade led by Saad Haddad. Letters exchanged by Israel and Washington tied Israel's withdrawal to Syria's, voiding the accord at birth in de Clerck and Malsagne's view. Picard places the signing at Naqoura.

The conference sat from 31 October to 4 November (Picard has 1 to 8 November), with Syria's foreign minister Khaddam present and Prime Minister Wazzan kept out by a Syrian veto. Amine Gemayel chaired; Camille Chamoun and Pierre Gemayel spoke for the Lebanese Front, Frangieh, Jumblatt and Karami for the opposition, Saeb Salam for the Sunnis, Adel Osseiran for the Shi'is.

Fourteen Super-Étendards from the carrier Clemenceau attacked the Sheikh Abdallah barracks and the Khawam hotel, used by the Revolutionary Guards and Islamic Amal. The barracks had been evacuated after a leak, and most bombs fell on nearby hills; de Clerck and Malsagne count two dead, an Iranian and a Lebanese shepherd. The raid, code-named 'Brochet', was presented as retaliation for the Drakkar bombing.
