De Clerck and Malsagne and Tegho Bou Nassif date Zahleh's entry into the war to 24 August 1975, when Palestinian fighters planted a bomb in its tourist district, Wadi al-Arayish. In Hanf's account, Zahleh's Christians and Shi'is of its outskirts and nearby villages, helped by Palestinian guerrillas, came to blows late in August after a non-political arcade quarrel. Three Zahleh men were executed at the end of August.

Hanf writes that once Jisr al-Pasha fell on 1 July the Palestinians struck in the north, taking coastal Chekka from Tripoli by way of the Koura, with massacres, looting and arson. A Lebanese Front counter-attack with army tanks reached Tripoli's outskirts.

Probably the text Picard lists as President Sarkis's 'Fourteen Points' (March 1980), one of the drafts that fed into the Taif Accord. Traboulsi notes that in that same month an American spokesman called on Lebanon to sign up to the Camp David accords.

According to Ménargues, Syria's foreign minister Abdel Halim Khaddam brought a five-page paper to Baabda on 5 May. In effect a Lebanese–Syrian accord on institutions, politics, the economy and culture, down to school curricula, it was rejected by the Kataeb leader Pierre Gemayel.

According to Picard, Hamid Frangieh negotiated Lebanon's financial agreements with France, which she places in 1943 rather than 1948.

A Palestinian Katyusha killed an Israeli motorist in Galilee on 5 June, a day of some 50 Israeli raids by Fisk's count, which left civilians burning in cars on the coast road north of Damour. Picard's chronology and one passage of de Clerck and Malsagne date the start of the invasion to 5 June; the books' main chronologies give 6 June.
