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.

Historians date the start of Operation Litani to 14 March (de Clerck and Malsagne, Traboulsi, Quéméner; de Clerck's chronology gives 15 March) and its end to 21 March. Up to 25,000 Israeli soldiers and 120 tanks took part (de Clerck and Malsagne). Estimates of the dead range from about 300 Palestinian fighters (de Clerck and Malsagne) to about 2,000 people, mostly civilians (Fisk; de Clerck and Malsagne; Picard). Estimates of the displaced range from 150,000 (Hanf's refugee table) and more than 200,000 (de Clerck and Malsagne, Picard) to 285,000 (Lebanese government figure cited by Fisk). On 15 March Israeli aircraft bombed the Palestinian camps of Beirut, Tyre and Damour.

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.

Bashir Gemayel was killed at about 4 p.m. during his weekly visit to the Kataeb office in Ashrafieh, nine days before taking office. The bomb, about 35 kilos of explosive, had been placed two days earlier in the flat above by Habib Tanios Chartouni, a member of the Syrian Social Nationalist Party, arrested on 16 September (Ménargues). Prime Minister Wazzan announced the death at midnight. Hanf counts 26 dead.

Early in 1983 the Eighth Brigade went into all of Beirut, the east included, under a plan to collect light arms in the city and clear heavy weapons and gunmen from Greater Beirut. The Lebanese Forces resisted, then on 1 March 1983 agreed to return East Beirut and the port's fifth basin to the state.

De Clerck and Malsagne say the deputies were told of the text at a closed session on 15 May; Prime Minister Wazzan approved it and sent it to the president, and that month 70 of the 91 deputies still in office backed the government.

Counts differ: Hanf has 64 for, 2 against and 4 abstentions among 70 deputies present (40 of 50 Christian and 24 of 41 Muslim members in favour); Traboulsi has 65 for, 2 against and 4 abstentions; Fisk puts the vote on 15 June. Traboulsi says the government formally renounced the agreement on 5 March 1984, Amine Gemayel never having signed it.
