The Parthians, although they perceived their dislodgment in the night, yet did not pursue them, but as soon as it was day, they came upon those that were left in the camp, and put no less than four thousand to the sword and with their light horse picked up a great many stragglers. Varguntinus, the lieutenant, while it was yet dark, had broken off from the main body with four cohorts which had strayed out of the way; and the Parthians encompassing these on a small hill, slew every man of them excepting twenty, who with their drawn swords forced their way through the thickest, and they admiring their courage, opened their ranks to the right and left, and let them pass without molestation to Carrhae.
Soon after a false report was brought to Surena, that Crassus, with his principal officers, had escaped, and that those who were got into Carrhae were but a confused rout of insignificant people, not worth further pursuit. Supposing, therefore, that he had lost the very crown and glory of his victory, and yet being uncertain whether it were so or not, and anxious to ascertain the fact, that so he should either stay and besiege Carrhae or follow Crassus, he sent one of his interpreters to the walls, commanding him in Latin to call for Crassus or Cassius, for that the general, Surena, desired a conference. As soon as Crassus heard this, he embraced the proposal, and soon after there came up a band of Arabians, who very well knew the faces of Crassus and Cassius, as having been frequently in the Roman camp before the battle. They having espied Cassius from the wall, told him that Surena desired a peace, and would give them safe convoy, if they would make a treaty with the king his master, and withdraw all their troops out of Mesopotamia; and this he thought most advisable for them both, before things came to the last extremity;Cassius, embracing the proposal, desired that a time and place might be appointed where Crassus and Surena might have an interview. The Arabians, having charged themselves with the message, went back to Surena, who was not a little rejoiced that Crassus was there to be besieged.
Next day, therefore, he came up with his army, insulting over the Romans, and haughtily demanded of them Crassus and Cassius, bound, if they expected any mercy. The Romans, seeing themselves deluded and mocked, were much troubled at it, but advising Crassus to lay aside his distant and empty hopes of aid from the Armenians, resolved to fly for it; and this design ought to have been kept private, till they were upon their way, and not have been told to any of the people of Carrhae. But Crassus let this also be known to Andromachus, the most faithless of men, nay, he was so infatuated as to choose him for his guide. The Parthians then, to be sure, had punctual intelligence of all that passed; but it being contrary to their usage, and also difficult for them to fight by night, and Crassus having chosen that time to set out, Andromachus, lest he should get the start too far of his pursuers, led him hither and thither, and at last conveyed him into the midst of morasses and places full of ditches, so that the Romans had a troublesome and perplexing journey of it, and some were who, supposing by these windings and turnings of Andromachus that no good was intended, resolved to follow him no further. And at last Cassius himself returned to Carrhae, and his guides, the Arabians, advising him to tarry there till the moon was got out of Scorpio, he told them that he was most afraid of Sagittarius, and so with five hundred horse went off to Syria. Others there were who, having got honest guides, took their way by the mountains called Sinnaca, and got into places of security by daybreak; these were five thousand under the command of Octavius, a very gallant man. But Crassus fared worse; day overtook him still deceived by Andromachus, and entangled in the fens and the difficult country. There were with him four cohorts of legionary soldiers, a very few horsemen, and five lictors, with whom having with great difficulty got into the way, and not being a mile and a half from Octavius, instead of going to join him, although the enemy were already upon him, he retreated to another hill, neither so defensible nor impassable for the horse, but lying under the hills at Sinnaca, and continued so as to join them in a long ridge through the plain. Octavius could see in what danger the general was, and himself, at first but slenderly followed, hurried to the rescue.
Soon after, the rest, upbraiding one another with baseness in forsaking their officers, marched down, and falling upon the Parthians, drove them from the hill, and compassing Crassus about, and fencing him with their shields, declared proudly, that no arrow in Parthia should ever touch their general, so long as there was a man of them left alive to protect him.
