Plutarch Antony 48

[1] Accordingly, the Romans went to pitching their tents, and the Parthians, as their custom was, at once began to withdraw. At this point Mithridates came again, and after Alexander had joined him he advised Antony to let the army rest only a little while, and then to get it under way and hasten to the river, assuring him that the Parthians would not cross it, but would continue the pursuit until they reached it. This message was carried to Antony by Alexander, who then brought out from Antony golden drinking-cups in great numbers, as well as bowls. Mithridates took as many of these as he could hide in his garments and rode off.

[2] Then, while it was still day, they broke camp and proceeded on their march. The enemy did not molest them, but they themselves made that night of all other nights the most grievous and fearful for themselves. For those who had gold or silver were slain and robbed of it, and the goods were plundered from the beasts of burden; and finally the baggage-carriers of Antony were attacked, and beakers and costly tables were cut to pieces or distributed about.

[3]
  And now, since there was great confusion and straggling throughout the whole army (for they thought that the enemy had fallen upon them and routed and dispersed them), Antony called one of the freedmen in his body-guard, Rhamnus by name, and made him take oath that, at the word of command, he would thrust his sword through him and cut off his head, that he might neither be taken alive by the enemy nor recognized when he was dead.

[4] Antony’s friends burst into tears, but the Mardian tried to encourage him, declaring that the river was near; for a breeze blowing from it was moist, and a cooler air in their faces made their breathing pleasanter. He said also that the time during which they had been marching made his estimate of the distance conclusive; for little of the night was now left.

[5] At the same time, too, others brought word that the tumult was a result of their own iniquitous and rapacious treatment of one another. Therefore, wishing to bring the throng into order after their wandering and distraction, Antony ordered the signal to be given for encampment.
