Apprehending the danger that the army would soon be entirely wiped out, P. Crassus applied to his father for permission to take his cavalry, together with some infantry and archers, and pierce the encircling line. M. Crassus endorsed the plan. This breakout force of some six thousand men moved forwards and the Parthians quickly withdrew. But although Publius had been expressly ordered not to pursue the enemy, he disobeyed these instructions. His men advanced out of sight of the main army, whereupon the Parthians reappeared behind them. Rapidly surrounded, Publius withdrew his men to a narrow ridge, where they presented an easy target. Once again the enemy’s archers did their murderous work. Perceiving the situation to be hopeless and fearing capture, Publius bade his men farewell and told them to look after their own safety. Then, since he was unable to use his hand, which had been pierced through with an arrow, he presented his side to his shield-bearer and ordered him to run him through with his sword. Most of his officers followed his example and put themselves to death.
Once they had overrun the Roman position, the Parthians cut off the head of Publius and mounted it on a spear. They then carried it back to the main Roman army and rode up and down our lines, taunting M. Crassus to come and look upon his son. Seeing what had happened, he addressed our men as follows: ‘Romans, this grief is a private thing of my own. But in you, who are safe and sound, abide the great fortune and the glory of Rome. And now, if you feel any pity for me, who have lost the best son that any father has ever had, show it in the fury with which you face the enemy.’
Regrettably, they paid no heed. On the contrary, this sight more than all the other dreadful things that had happened broke the spirit and paralysed the energies of our forces. The airborne slaughter resumed, and it is a certainty that the entire army would have been annihilated had not night fallen and the Parthians withdrawn, shouting that they would give Crassus the night to grieve for his son and would return to finish us off in the morning.
