During this time, Crassus, relieved by his son’s offensive movement, had taken position on a height, and waited in expectation of his victorious return. But soon messengers come to inform him that, without prompt succour, his son is lost. He hesitates a moment between the hope of saving him and the fear of endangering the rest of his army. At last he decides on marching. Hardly has he put the troops in motion, when he sees the Parthians approaching to meet him, uttering shouts of victory, and carrying the head of his son on the end of a pike. In this circumstance, Crassus recovers an instant that energy familiar to the Roman character, and, passing along the ranks, “Soldiers,” he exclaims, “this loss concerns me alone. As long as you live, all the fortune and all the glory of Rome endure and remain invincible. Be not discouraged by my misfortune, and let your compassion for me be changed into rage against your enemies.” These last accents of a presumptuous chief produced little effect upon an army already disheartened. It fought with resignation, no longer feeling that ardour which gives the hope of victory. Taken in flank by the numerous archers, attacked in front by the heavy cuirassed cavalry, the Romans struggled till evening, remaining always on the defensive, and seeing the circle in which they were enclosed incessantly contracting around them. Fortunately, the Parthians, incapable of holding a position during the night, never encamped on the field of battle; they withdrew. This combat, fought at fifteen or twenty leagues to the south of Carrhæ, was disastrous. Nevertheless, all was not lost, if the general-in-chief preserved his energy and presence of mind; but, disheartened and plunged in deep grief, he stood immovable, aside from the rest, incapable of giving any order. Octavius and Cassius called together the tribunes and centurions, and decided on retreat; yet it was necessary to abandon 4,000 wounded, who could not be carried away, and even conceal their departure from them, lest their cries might awaken the attention of the enemy. The retreat is executed at first in complete silence; suddenly the miserable victims perceive that they are made a sacrifice, their groans give warning to the Persians, and excite a frightful tumult among the Romans: some return to load the wounded on the baggage horses, others form in battle to repulse the enemy: 300 of the cavalry escape, reach Carrhæ, and cross the Euphrates over the bridge which Crassus had built. Meanwhile the Parthians, occupied in massacring the 4,000 wounded and the stragglers, pursue only faintly the remains of the Roman army, which, protected by a sally of the garrison of Carrhæ, succeed in shutting themselves up within its walls.
