Ménargues dates the resignation to March 1980, after repeated deadlock between Hoss and Sarkis over the army; Hoss stayed on as caretaker until Shafiq Wazzan's appointment in late October.

The invasion, called 'Operation Peace for Galilee', began on Sunday 6 June: Israeli commandos crossed the border at 1.30 a.m. to attack Beaufort castle (Ménargues), and up to 25,000 troops moved along the coast, through Tibnin and across the eastern sector (Fisk). The government declared a limited aim of a 40-kilometre zone, but Defence Minister Ariel Sharon and Chief of Staff Rafael Eitan kept advancing (Hanf). One overview in de Clerck and Malsagne and Picard's chronology give 5 June.

The fighting set Fatah dissidents under Abu Musa, Syrian artillery and pro-Syrian Lebanese parties against Arafat's loyalists and the Sunni Tawhid militia. Hanf writes that in early November it took on the character of a Sunni-Alawite civil war, and that Tawhid fighters killed hundreds of communists.

Israeli losses: de Clerck and Malsagne count 670 dead and nearly 3,000 wounded between June 1982 and June 1985 (and 721 dead and 3,890 wounded for the whole war); Traboulsi writes of some 500 dead. Israel kept a 'security zone' policed with Lahad's South Lebanon Army.

According to Hanf and Fisk, the embassy closed after demonstrations by Aoun's supporters. A first youth protest at the embassy, against Western 'silence', took place in April 1989.
