De Clerck and Malsagne and Traboulsi date the Sidon fishermen's protest to 26 February 1975. The marchers opposed Protein, a fishing company whose board included Camille Chamoun; their leader, Maarouf Saad, was shot and died some days later. Clashes between the army and armed groups in Sidon and Tyre followed at the start of March: de Clerck and Malsagne give 6 soldiers and 11 civilians killed and an army pull-out from Tyre, Hanf 5 soldiers and 11 civilians. The Kataeb staged a pro-army demonstration in Beirut. Hanf puts the fishermen's protest in March, and Picard describes the Sidon marchers as Palestinian militants.

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.

Formed in September 1975 through Syria's foreign minister Abdel Halim Khaddam, the National Dialogue Committee of some twenty leaders debated secularism and ending sectarian quotas; Hanf says it broke up empty-handed.

Haugbolle notes widespread protests on National Day in November 1975; Hanf places the war's first demonstration in that month, when gunmen held fire until tens of thousands from East and West Beirut, summoned by television announcer Sharif Akhawi, had gone home.

Begun in late October 1975 (20 October in de Clerck and Malsagne's chronology), the Battle of the Hotels ran for five months, ending when the Holiday Inn fell on 20-22 March 1976. Traboulsi links its launch to Black Saturday in December.

The bodies of four young Kataeb members were found on 6 December 1975, while Pierre Gemayel was in Damascus; Muslims seized at makeshift checkpoints by the port were killed in reprisal. Accounts place the bodies in the Metn (Hanf), near Tal al-Za'tar (Haugbolle) or outside the electricity company offices (Fisk). De Clerck and Malsagne blame Joseph Saadeh, whose son was among the four. Only Fisk puts Bashir Gemayel in Damascus and cites Phalangist officers saying he ordered the reprisal. The Muslim dead number about 200 (Hanf, Traboulsi, de Clerck and Malsagne) or several dozen (Picard); Fisk gives at least 300 Muslims, and probably as many Christians, in the reprisals.

Hanf has the Murabitun, discreetly backed by the Palestinians, going on the offensive against the Kataeb downtown and around the hotels on 8 December and seizing the Phoenicia and St Georges. Traboulsi places an army attempt to retake the two hotels on 9 December.

Bishop Yuhanna Bassul's diary records 500 shells hitting Zahleh on the night of 22 December, with some 15,000 fedayeen gathered in the plain; at his appeal the army's Maghawir commando regiment came to help. Hanf writes that 3,000 men of the PLA's Yarmouk Brigade had entered from Syria on 20 December and besieged the town, which Syrian positions also shelled.

On 11 March Brigadier-General Aziz al-Ahdab, Beirut garrison commander (retired, says Traboulsi), seized the television station, named himself interim military governor and called for Frangieh's resignation and an early election. Few troops stood behind him and Syria opposed him: on 15 March PLA and Saiqa units under Syrian control blocked his men and Khatib's Lebanese Arab Army on their way to Baabda. Backed by Chamoun, Gemayel and President Assad, Frangieh refused to go.

The deputies' petition demanding Frangieh's resignation is dated 11 March in Traboulsi's chronology and 13 March by de Clerck and Malsagne; Picard and Traboulsi's chronology count 68 signatures out of 99, Traboulsi's narrative 69. On 15 March Syrian-controlled PLA and Saiqa units halted a march on the Baabda palace by the Lebanese Arab Army and al-Ahdab's followers. Within days Khatib's force grew to a few thousand men and held most of the army's heavy weapons.

Mourabitoun and Palestinian fighters, backed by Lebanese Arab Army artillery, took the 24-storey Holiday Inn after a fight waged floor by floor, day and night, from 20 to 22 March 1976 (Traboulsi dates the fall to 22 March). The Kataeb withdrew to the Fattal building near the port. The five-month Battle of the Hotels was over, and Beirut was split along the Green Line.

Hanf traces the line that went on dividing the city along the Damascus road and across Martyrs Square to the harbour. It was set once the Kataeb, losing the Holiday Inn, had no positions left in West Beirut.

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.

Hanf writes that Damascus thought the Christian side had won ground enough over the summer, so Syrian guns blocked the Lebanese Front's bid to cross the Beirut-Damascus road and take Aley. Kataeb fighters who had lost comrades at Aley the day before then killed Druze civilians at Salima (de Clerck and Malsagne).

Talks in France with the government and Mitterrand's opposition left Jumblatt sure that France could do nothing in Lebanon against Syrian and US opposition (Traboulsi). His tour, by boat from encircled West Beirut to Cyprus, then Cairo, Algiers and Paris, sought Arab contingents to offset the Syrians.

Ratified by an Arab summit in Cairo on 25 October, the Riyadh decisions required all parties to surrender heavy weapons and the Palestinians to return to the zones granted by the 1969 Cairo Agreement, and created a 30,000-man Arab Deterrent Force under President Sarkis, its largest contingent by far, 25,000-27,000 men, being the Syrian troops already in Lebanon. Saudi Arabia had sent the invitations on 15 October; the leaders of Saudi Arabia, Kuwait, Egypt, Syria and Lebanon met the PLO chairman in Riyadh on 16, 17 or 18 October, depending on the historian. The cease-fire's start is dated 16 October (Hanf), 21 October (Traboulsi) or 15 November (de Clerck and Malsagne).

In 1976 Major Saad Haddad's force was known as the Army of Free Lebanon; it took the name South Lebanon Army only in 1985. Agreed through American mediation, the 'red line' kept Syrian and other Arab troops out of the south, where Palestinians and Christian militias kept fighting and Israel backed Haddad (Hanf).

Its members were technocrats and businessmen; the one politician, Fouad Boutros, held both foreign affairs and defence (Traboulsi). Early on, at Syria's behest, it brought in press censorship (Hanf, Fisk); Traboulsi also mentions an order for militias to surrender their arms.

Jumblatt was ambushed near a Syrian checkpoint of the Arab Deterrent Force; Fisk places it on the mountain road near Baaqlin. Most historians give 16 March 1977 (Traboulsi, de Clerck and Malsagne, the Confluences authors, and Hanf on one page); Hanf elsewhere and Ménargues give 17 March, which Ménargues ties to the burial. His son Walid took over, and Christians were killed in reprisal in Chouf villages. Hanf writes that most politicians, Muslims above all, took the murder as a warning against defying Syria openly, and that Jumblatt had attacked the Syrian presence in speech and print, in Lebanon and abroad.

The force is usually called the Arab Deterrent Force (ADF) in English.

The bombing came the evening the government chose a new army commander, a change arranged by Boutros, who held foreign affairs and defence, and regarded by the Christian parties as cause for war.
