While the Muslims were occupied at Fahl, Heraclius, sensing an opportunity, quickly sent an army under General Theodras to recapture Damascus, where a small Muslim garrison was left. Shortly thereafter, the Muslims, having just won the Battle of Fahl, were on their way to Emesa. In the meantime, the Byzantine army split in two, one deployed at Maraj al Rome (Beqaa Valley) led by Schinos; the other, commanded by Theodras, stationed to the west of Damascus (Al-Sabboura region). During the night, Theodras advanced to Damascus to launch a surprise attack.
