January 1975 saw heavy Israeli attacks on the South. Israeli forces razed Kfar Chouba, a border village, about a week after 7 January (Hanf), and Palestinian commandos shelled army positions in Tyre during border clashes with the Lebanese army (de Clerck and Malsagne). The figures for 3 January come from contemporary press reports.

Traboulsi counts this among the early-1975 protests, a southern general strike and Beirut demonstrations, over the Palestinian presence and the south's defence.

Antoine Khuraych headed the Maronite Church from his election on 3 February 1975 (enthronement 9 February) until 1986, styling himself the 'patriarch of dialogue'.

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.

De Clerck and Malsagne date the siege of Tal al-Za'tar from 4 January 1976 to the camp's fall on 12 August. According to Hanf, Interior Minister Camille Chamoun had Internal Security Forces units join the assault.

De Clerck and Malsagne record that the besiegers executed some twenty Damour residents on this day, a first massacre a week after the siege began on 9 January. Whether these are the deaths reported 'at the entry of Damour' is not established.

Dates differ between historians: 16 January (Ménargues), 18 January (de Clerck and Malsagne; consistent with Fisk), 19 January (Hanf), 20 or 22 January (Traboulsi). Maslakh, next door, fell at the same time. Most of the district's people were Shi'is, living alongside Palestinians, Kurds and Armenian Lebanese. Haugbolle estimates 150-500 dead, de Clerck and Malsagne 600-1,000; some 30,000 people were driven out to West Beirut and the southern suburbs.

The siege of Damour had begun on 9 January, before the fall of Karantina; the main massacre began on 20 January (Hanf, Ménargues, Fisk, de Clerck and Malsagne; Traboulsi gives 22 or 24 January). Jiyeh fell the same day. The attackers were mainly PLA, Saiqa and Fatah units, with Lebanese leftist parties. Estimates of the dead range from about 150 bodies found plus 200 missing (Fisk) and 300-584 (de Clerck and Malsagne) to about 900 (Ménargues); some 5,000 people fled by land and sea.

Traboulsi, de Clerck and Malsagne, and Yara El Khoury date the Syrian-mediated cease-fire to 23 January. PLA and Saiqa units attacked Zgharta in the north but were repulsed, and Zahleh, besieged, held out.

Historians date Lieutenant Ahmad al-Khatib's breakaway to 21 January (de Clerck and Malsagne, in the Bekaa) or 22 January (Julie Tegho Bou Nassif, from the diary of the Greek Catholic bishop of Zahleh); Hanf places the mutiny in the south. About 300-400 Muslim soldiers followed him at first. The entry of 30 January may record a later step.

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.
