The day began with shootings near the church in Ain al-Rummaneh, where Pierre Gemayel was attending a consecration; his bodyguard Joseph Bou Assi was killed. In the early afternoon Kataeb militiamen fired on a bus returning to Tal al-Za'tar from a rally of the Arab Liberation Front. Most historians count 27 dead (Hanf, Fisk, de Clerck and Malsagne: 27 of 35 passengers); Traboulsi gives 21 and Ménargues 31. According to de Clerck and Malsagne the bus carried Palestinians and Lebanese in equal numbers, all men. Fighting spread that evening across the suburbs of Beirut.

After several days of fighting (Hanf; four, says Traboulsi), Pierre Gemayel gave up to the police two militiamen implicated in the Ain al-Rummaneh shooting. Early Syrian mediation failed to stop this round, which de Clerck and Malsagne end with a cease-fire on 16 May 1975; no book confirms a truce on 15 April.

In a heated sitting of parliament Rashid al-Solh resigned, blaming the Kataeb for the fighting. His refusal to deploy the army had led the Kataeb ministers to leave the cabinet, and other Christian ministers had followed them.

Nureddine al-Rifai was a retired Sunni officer: a general according to Hanf, a brigadier-general according to Traboulsi, an officer of the gendarmerie according to de Clerck and Malsagne.

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.

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.

Historians describe the Tripoli-Zgharta round as following the Zahleh fighting of late August: kidnappings on both sides, the killing of twelve Muslim bus passengers on the Beirut-Tripoli road, attacks on Christian villages in Akkar and the flight of Christians from Tripoli and Akkar. It ended when the army created a buffer zone between the two towns.

Hanf: Franjieh accepted Karami's condition for sending the army between Tripoli and Zgharta, Ghanem's removal; his replacement, Hanna Said, was a 'politically uncontentious' colonel.

De Clerck and Malsagne date the start of fighting in central Beirut to the night of 17-18 September 1975; Hanf and Traboulsi hold the Kataeb responsible for shelling the old souks. A cease-fire and the setting-up of the National Dialogue Committee followed.

De Clerck and Malsagne date the start of bread rationing to September 1975.

Cardinal Paolo Bertoli's mission lasted from 9 to 14 November 1975 (de Clerck and Malsagne's chronology). Like the French envoy Couve de Murville, he backed a limited revision of the National Pact.

Parliament used the truce to amend Article 73 of the constitution so that Frangieh's successor could be elected early: on 9 April according to Hanf, 10 April according to Yara El Khoury. The truce had coincided with the arrival on 31 March of the US envoy Dean Brown.

Traboulsi's chronology puts the Syrian-PLO accord to restore order in Beirut on 11 April. Around 9 April Syrian army tanks entered the Bekaa at Anjar, Judaydat Yabus and Bayadir al-Adas (Traboulsi), some forty in all according to Yara El Khoury, as Saiqa fighters set about ending the siege of Zahleh.

Accounts differ. Hanf has Raymond Eddé stand 'on principle', protesting at outside manipulation, and so become the Left's candidate; Traboulsi and de Clerck and Malsagne have him boycott the vote, Traboulsi because it could not be free.

Hanf and Ménargues count 66 votes for Sarkis out of 69 cast; de Clerck and Malsagne give 70. National Movement and PLO mortars fired as deputies, escorted by Saiqa, PLA or Syrian troops, met at the Villa Mansour on the demarcation line. Votes were reportedly bought, by Syria (de Clerck and Malsagne) or with Saudi and CIA money (Traboulsi). Sarkis was sworn in only on 23 September.

De Clerck and Malsagne note that Edouard Saab was Le Monde's correspondent too; a sniper shot him dead while he crossed the demarcation line.

De Clerck and Malsagne record three attempts on Raymond Eddé's life, one outside his home, before his voluntary exile in Paris from January 1977; Picard dates the exile to December 1976.

On 2 June Bashir Gemayel, having asked for a secret meeting with Kamal Jumblatt, offered him condolences and information on who had killed her. Traboulsi names her Linda al-Atrash and puts her apartment in East Beirut.

Tal al-Za'tar fell on 12 August 1976 (13 August in Ménargues) after more than 70 assaults. Ménargues and Hanf count a siege of 52-53 days from the final offensive; de Clerck and Malsagne and Traboulsi count six months from the January blockade. An ICRC report cited by de Clerck and Malsagne puts the dead at about 2,500 residents and defenders and up to 800 attackers; many died trying to escape. The Tigers and the Guardians of the Cedar led the last assault, reportedly with Syrian and Israeli officers present. The camp was bulldozed and never rebuilt.

Hanf has the Syrian army moving again only once Tal al-Za'tar had fallen, increasing pressure on the encircled Palestinian and leftist forces in the Upper Metn; these were expelled at the end of September.

Historians disagree on 1976: Haugbolle ranks it among the war's largest emigration waves, while de Clerck and Malsagne see many returning that year after nearly 400,000 Lebanese had left by 1975. Haugbolle notes that no official figures exist.

Ménargues dates the formal unification of the Christian militias under Bashir Gemayel's command to 31 August 1976; Yara El Khoury has it announced to President Frangieh in early September 1976. According to de Clerck and Malsagne, 'Lebanese Forces' was not the official name until 1981, but the unified command was officially founded on 25 March 1976.

Syrian helicopters and armoured limousines carried the 67 deputies to the Park Hotel in Chtaura, in the Syrian-held Bekaa, where 2,000 Syrian soldiers and 40 tanks guarded the ceremony (Fisk). Sarkis used his address to declare that Lebanon itself had invited the Syrian army in (Hanf).

From Sarkis's inauguration on 23 September Hanf counts three quiet days, the Semiramis Hotel attack in Damascus and a Syrian move two days after it, placing this offensive at about 28 September. The Palestinian and leftist forces lost the Upper Metn; Traboulsi notes that the Joint Forces' largest concentration, there under Abu Khalid al-Amleh, never engaged the advancing Syrians.

Ménargues names only Sami al-Khatib. Traboulsi confirms that the Arab Deterrent Force's first Lebanese commander was Ahmad al-Hajj, who did not gain Syria's favour and was quickly replaced by al-Khatib.

Fisk: Kahhaleh showed white flags and Hazmiyeh's Christians threw rice and rose water at the crews as at least 20 miles of Syrian tanks, guns and troop carriers came down on Beirut from dawn on 10 November.

De Clerck and Malsagne report that Eddé went into exile in Paris after surviving three attempts on his life, one of them outside his home.
