VII. He was careful not to send any Macedonians to attack Kraterus, but entrusted this duty to two divisions of cavalry, which he placed under the command respectively of Pharnabazus the son of Artabazus and Phœnix of Tenedos. These he ordered, as soon as they saw the enemy, to charge at full speed, and not to give them time for any parley, or to send a herald; for he was grievously afraid that if the Macedonians recognized Kraterus they would desert to him. He himself formed three hundred of the best of his cavalry into a compact mass with which he proceeded towards the right, to engage the detachment under Neoptolemus. The main body, as soon as it had passed a small hill, came in sight of the enemy and at once charged at full gallop. Kraterus at this broke out into violent abuse of Neoptolemus, saying that he had been deceived by him about the Macedonians who were to have deserted. However, he called upon those about him to quit them like men, and advanced to meet the horsemen.

The shock was terrible. Their spears were soon broken, and the fight was continued with swords. Kraterus proved no unworthy successor of Alexander, for he slew many and often rallied his troops, until a Thracian rode at him sideways and struck him from his horse. No one recognized him as he lay on the ground except Gorgias, one of the generals of Eumenes, who at once dismounted and kept guard over him, although he was grievously hurt and almost in the death-agony.

Meanwhile Eumenes encountered Neoptolemus. Each had a long-standing grudge against the other; but it chanced that in the first two charges which took place they did not see one another. The third time they recognized one another, and at once drew their daggers and rode together with loud shouts of defiance. With their reins flowing loose they drove their horses against one another like two triremes, and each clutched at the other as he passed, so that each tore the helmet from the other's head, and burst the fastenings of the corslet upon his shoulder. Both fell from their horses, and wrestled together in deadly strife on the ground. As Neoptolemus strove to rise, Eumenes struck him behind the knee, and leaped upon his own feet, but Neoptolemus rested upon his other knee, and continued the fight until he received a mortal stab in the neck. Eumenes through the mortal hate which he bore him at once fell to stripping him of his armour and abusing him, forgetting that he was still alive. He received a slight stab in the groin, but the wound frightened Eumenes more than it hurt him, as the hand that dealt it was almost powerless. Yet when Eumenes had finished despoiling the corpse he found that he was severely cut about the arms and thighs, in spite of which he remounted his horse, and rode to the other side of the battle-field, where he thought the enemy might still be offering resistance. Here he heard of the death of Kraterus, and rode up to where he lay. Finding that he was still alive and conscious, Eumenes dismounted, and with tears and protestations of friendship cursed Neoptolemus and lamented his hard fate, which had forced him either to kill his old friend and comrade or to perish at his hands.
