Hanf notes that in December 1977 Menachem Begin, Israel's prime minister, had excluded any return of the Palestinian refugees in neighbouring countries.

Historians date the Fayadiyeh incident to 7 February (de Clerck and Malsagne), 8 February (Hanf) or 17 February (Ménargues). It began when Syrian soldiers set up a roadblock in front of the Military Academy; officer cadets, led according to de Clerck and Malsagne by Captain Samir (Sami) al-Achkar, fought back and Syrian artillery shelled the barracks. Syrian losses are given as 13 dead and 36 wounded (de Clerck and Malsagne), over 30 dead (Ménargues) or 220 dead and 30 wounded (Hanf). As fighting spread into East Beirut, about a hundred people died when Syrian guns shelled Badaro, Ain el-Remmaneh and Karm el-Zeitoun. Sarkis and Damascus settled the affair with a joint Lebanese-Syrian military court. De Clerck and Malsagne date the Syria-Christian split to it.

De Clerck and Malsagne and Haugbolle list this 1978 play first among Ziad Rahbani's comedies, which satirised the war from West Beirut.

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.

Resolution 425 was adopted with Resolution 426, which set up the force; the USSR abstained (de Clerck and Malsagne). UNIFIL later numbered about 6,000 soldiers, with France providing the largest first contingent (1,290 men).

Fisk dates the arrival in Tyre of UNIFIL's first unit, Colonel Jean Germain Salvan's French paratroopers, to 23 March. That morning, at the nearby Hassan Borro barracks, Palestinians and Lebanese officers nearly opened fire over the handover.

Fisk adds that during the invasion Gur declared that Israel would fall back to the Christian enclaves as a border 'security belt': the strip that became Major Haddad's.

By now Syria was fighting on the Palestinians' side. Hanf says the clashes ended once the Arab Deterrent Force's Saudi and Sudanese contingents deployed between Chiyah and Ain el-Remmaneh.

Neither parliament nor president could enforce the resolution, Hanf notes. The 74 deputies in attendance passed it without dissent: it reserved arms to the legitimate Lebanese forces, told the Palestinians and 'other parties' to end armed action, and applied Lebanese law to all on Lebanese soil.

Colonel Jean Germain Salvan was badly hurt in both legs in early May, Fisk writes, when dissident PLO gunmen fired on the Fatah jeep carrying him, killing a French soldier and his Palestinian driver; Arafat called it a crime. Hanf adds that such losses made the French unit much more careful.

De Clerck and Malsagne record that Frangieh had quit the Lebanese Front the day before over its ties with Israel. The reconciliation, Hanf notes, made the north a pro-Syrian bloc.

Historians date the Ehden killings to 13 June (de Clerck and Malsagne) or 14 June (Hanf). A unit of some 200 men (Traboulsi) led by Samir Geagea attacked the Frangieh residence; besides Tony Frangieh, his wife and their three-year-old daughter, about thirty relatives and supporters were killed. The Phalange presented the raid as retaliation for the killing of their local leader Jud al-Bayeh in early June; Bashir Gemayel denied ordering the killing of the family. The raid also turned on control of the Chekka cement works. Syrian troops then occupied Ehden and much of the north.

Hanf writes that the Lebanese Front was left with an enclave of roughly a tenth of Lebanon once Syrian troops had moved into the northern Christian mountains, Koura, Batroun and the coast as far as the Madfoun bridge. Frangieh gave Kataeb members in the north until the month's end to give up their weapons and quit the party, or else leave.

The Qaa massacre is dated to the night of 27-28 June (de Clerck and Malsagne) or to 29 June (Hanf); Ras Baalbek and Jdeidet al-Fakiha were also raided. De Clerck and Malsagne blame Syrians in civilian clothes, carrying name lists and guided by local Christian members of the SSNP and the Communist Party, and see the killings as revenge for Ehden. Hanf counts 26 dead, de Clerck and Malsagne 32 to 36. The community's Supreme Council asked that a day of national mourning be held.

Hanf has Syrian guns shelling Ain el-Remmaneh on the day of mourning called after the Qaa killings, and the Syrian troops ignoring Sarkis's order to cease fire. Ménargues puts Bashir Gemayel's brief detention at a Syrian checkpoint at the end of July.
