On 15 June, Israel offered free passage to all Syrian forces in Beirut if they would withdraw from the city to the Bekaa Valley in the east, but the Syrian government refused and sent further reinforcements to its units along the highway and north of the highway near Beirut. The Israelis faced Syrian strongpoints reinforced by armor and artillery all along the highway. However, between 16 June and 22 June, the fighting was limited to artillery duels and minor firefights between Israeli and Syrian forces, as both sides reinforced their troops.[1]
