Syria, Hanf writes, had lost interest in disarming the Palestinians by autumn 1977, with Sadat's initiative under way, and the deal soon counted for nothing. It had bound the PLO to keep out of a ten-kilometre belt beside the Israeli frontier and, chiefly, to halt raids and shelling across it.

Robert Fisk, who reported from the area, saw Israeli tanks on Lebanese soil near Ibl al-Saqi and Israeli shelling of Christian villages such as Rachaya al-Fukhar, where Palestinian guerrillas had dug in.

Israel's Christian allies emerged with a slightly wider strip, spanning nearly the whole frontier from sea to Hermon; Fisk dates the tank withdrawal to 26 September.

Hanf has Syrian guns shelling Ain el-Remmaneh on the day of mourning called after the Qaa killings, and the Syrian troops ignoring Sarkis's order to cease fire. Ménargues puts Bashir Gemayel's brief detention at a Syrian checkpoint at the end of July.

Fisk adds that the Syrian shelling slackened around this time after sonic booms from a pair of Israeli jets flying low over West Beirut.

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.

Musa al-Sadr travelled to Libya on 25 August (de Clerck and Malsagne) at the invitation of the Libyan government (Ménargues) and was never seen again; Hanf dates the disappearance to September. Beirut papers speculated about the Shah's secret police or Libyan intelligence. Fisk writes that he was almost certainly killed in Libya. The loss mobilised the Shi'a and later strengthened Amal.

Schools, hospitals and factories were destroyed in the new bombardment, and Lebanese gendarmes logged 2,000 impacts a day in Achrafieh. Hanf links it to the Camp David agreement reached a few days before.

In February 1978 Achkar had led the Lebanese soldiers in the clash with Syrian troops at Fayadiyeh; in October he left the army with about twenty men and founded a 'Revolutionary Lebanese Army Movement'. Boutros was due to fly with the president to the Arab summit in Baghdad when the Lebanese Forces, avenging Achkar, ambushed him on the way to the airport. Lieutenant Qozhaya Chamoun, who led the convoy, was abducted and later murdered; Boutros himself got away.

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.
