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.

Fisk: after shells killed two Nigerian UNIFIL soldiers in March 1981, the force commander, General William Callaghan, blamed Israeli gunners rather than Haddad's militia.

Historians date the battle of Zahleh from this day, when Lebanese Forces fighters beat off a Syrian attack on the town and a siege of some 90 days began. Ménargues says Syrian heavy guns killed 50 and wounded over 200 that day in Zahleh and the Christian zone north of Beirut.

Ménargues dates a day of intensive shelling of Zahleh, with about twenty dead, to 6 April.

Ménargues writes that Syrian special forces, landed by helicopter at dawn on 10 April, soon took the heights of Qalaat Aramta and Deir Charfé around Zahleh, leaving its defenders almost encircled.

According to Ménargues, Bashir Gemayel answered the collapse of a cease-fire on 22 April, which left 140 dead or wounded in Beirut within hours, by having the international airport shelled. On 11 May US ambassador John Gunther Dean urged the Lebanese Forces, via Alfred Madi, to let it reopen; that evening they dropped their objection.

Ménargues has two Syrian helicopters downed: a Mi-8 supply craft, hit by F-15s around noon just after leaving Rayak, and a French-built Alouette late in the day; in between, jets struck ADF positions around Sannine. Israel acted at Christian leaders' request once Syria held Sannine's summit; next day Syria answered with surface-to-air missiles in the Bekaa.
