Battle of Zahleh

Battle context

The Battle of Zahleh was a prolonged confrontation within the Lebanese Civil War that centered on Syrian efforts to prevent a potential Lebanese Forces–Israeli alignment in a strategically sensitive zone. Zahleh's position adjacent to the Bekaa Valley—which runs along the Syrian border—and its proximity to the Beirut-Damascus highway made the city a focal point for Syrian security calculations. The Syrian Armed Forces, operating nominally as the Arab Deterrent Force, moved to control major roads leading into and out of the city and fortified the surrounding valley, framing the operation as a national security measure against a perceived encirclement threat. The engagement placed the Lebanese Forces under Bachir Gemayel in direct confrontation with Syrian military power, with Zahlawi residents joining the resistance. Lasting roughly seven months from late 1980 into mid-1981, the battle illustrated the extent to which the Syrian military presence in Lebanon functioned as an active party to the civil conflict rather than a neutral peacekeeping body, and it sharpened the polarization between the LF and Damascus at a critical juncture in the war.
