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.

Historians date the battle of Zahleh from this day, when Lebanese Forces fighters beat off a Syrian attack on the town and a siege of some 90 days began. Ménargues says Syrian heavy guns killed 50 and wounded over 200 that day in Zahleh and the Christian zone north of Beirut.

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.

The meetings produced no agreement (Hanf).

Under the 5 April accord, reached by Amal, the PLO and the pro-Syrian Palestinian National Salvation Front with the Syrian general Ghazi Kanaan present, the blockade was to be lifted, the wounded taken out and the PLO was to leave three villages near Sidon. Food and medicine then reached Chatila and Bourj al-Barajneh, the first since March. Picard dates the end of the siege to an Amal-Palestinian agreement of 11 September 1987; Hanf has Amal lifting the blockade only on 18 January 1988.

De Clerck (p. 350) places the traffic in 1987 and implicates the Lebanese Forces. Its figures, from Greenpeace: 15,800 barrels and 20 containers from Italy, of which 5,500 barrels went back in 1988-1989; the rest was burned, dumped or buried, partly in the Kesrouan mountains.

Hanf: when Damascus protested, Paris called envoy Deniau's description of Syria as the aggressor in Lebanon his 'private opinion'.

Hanf says 300 Lebanese Forces militiamen stayed at Karantina and the port after the December 1990 withdrawal, and dates the army's entry into the Fifth Basin and other militia ports to 11 March 1991.
