For the first two hours or so the fighting continued at a steady pace with neither side making any headway; but soon after midday, the superior strength of the Romans began to tell and the battle turned in their favor. The Romans were able to move forces around both Muslim flanks, and the fighting increased in intensity. The temper of the Muslims became suicidal as the real danger of their position became evident and they fought ferociously to avoid encirclement, which appeared to be the Roman design. By early afternoon the Roman wings had moved further forward, and the encirclement of Shurahbil's force became a virtual certainty. Then suddenly the combatants became aware of a powerful force of cavalry galloping in mass towards the battlefield from the northwest.
