After the Israeli advance, Lebanese Forces militiamen set up checkpoints in the Chouf and Aley; clashes with Druze fighters followed and the Israelis often mediated (Hanf). De Clerck and Malsagne date the 'Mountain War' from summer 1982, the Lebanese Forces fighting first the SSNP's Druze and then the PSP.

Hanf and de Clerck and Malsagne mention an undated peace march by war-disabled people, some on crutches or in wheelchairs: Tripoli to Beirut in Hanf, Halba to Tyre in de Clerck and Malsagne. Whether this is the October 1987 march is not established.

At about 7 a.m. on 13 October 1990 Syrian aircraft started bombing Baabda, and Syrian and Lebanese armour moved in from West Beirut and the mountains. Some two and a half hours later Aoun went to the French embassy; with Ambassador René Ala mediating, and at Hrawi's demand, he told his troops over the radio to obey General Lahoud. Within about eight hours the fighting had ended. Tolls vary: over 200 dead in a single morning (de Clerck and Malsagne); some 400 Syrian soldiers dead (Hanf); 160 Syrian soldiers dead at Dahr el-Wahash alone, by Syrian figures (Fisk); and an initial government figure of 36 dead (Fisk). Picard's chronology places the Syrian attack on 12 October.
