Eniopeus

And as he came straight for them, the son of Tydeus cast his spear, but missed him, and it was Hector’s henchman and charioteer, Eniopeus, the son of high-hearted Thebaios, he struck in the chest beside his breast as he held the horses’ reins; he fell from the chariot, the swift-footed horses started, and there his soul and strength were undone. Dreadful grief closed over Hector’s heart for his charioteer; that he let him lie, grieving though he was for his companion, and drove in search of a bold charioteer; nor was it long his horses lacked a master; for Hector swiftly found the bold son of Iphitos, Archeptolemos, whom he then made mount behind the swift-footed horses, and gave the reins into his hands.

Gorgythion

He spoke, and let loose another arrow from his bowstring straight at Hector, and his heart strained to hit him; but he missed him, and struck instead blameless Gorgythion in the chest with his arrow, Priam’s worthy son, whom his mother bore, she who was taken as wife from the town of Aisyme, beautiful Kastianeira like to a goddess in figure; his head hung to one side like a garden poppy made heavy with seed and the showers of spring; so his head drooped, weighed down by his helmet.

Archeptolemus

Teucer let loose another arrow from his bowstring straight at Hector, and his heart strained to hit him; but he missed even this time, for Apollo thwarted him, and it was Archeptolemos, Hector’s bold charioteer, he struck in the chest beside his breast as he rushed to the fighting; he fell from the chariot, the swift-footed horses started, and there his soul and strength were undone. Dreadful grief closed over Hector’s heart for his charioteer; but he let him lie, grieving though he was for his companion, and summoned Kebriones, his brother, who was nearby, to take the horses’ reins; and when he heard he did not disobey. Hector leapt from his gleaming chariot to the ground crying a dreadful cry; and took a stone in his hand, and made straight for Teucer, his heart urgent to strike.

Cebriones

And Patroclus from his side jumped from behind his horses to the ground, holding his spear in his left hand, and with the other he seized a rock glittering and jagged, which his hand covered over, and with his strength behind it he hurled; he did not long stand in awe of the man, nor was his cast in vain, but he struck Hector’s charioteer Kebriones, a bastard son of worthy Priam, between his eyes with the sharp rock as he held the horses’ reins. The stone shattered his brows, the bone did not hold, his eyes fell to the ground in the dust before his feet; and he, like a diver, dropped from the strong-made chariot, and his spirit left his bones.

The Gorgythion and Archeptolemus deaths happen literally one after the other - there are no additional lines between the excerpts I posted for them (which are from Caroline Alexander’s translation).
