The National Movement's call for a general strike, supported by the leading Sunni politicians, Mufti Hassan Khaled, Musa al-Sadr and Raymond Edde, brought down the military cabinet on 26 May; on 28 May Frangieh appointed Rashid Karami Prime Minister.

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.

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

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.
