Achilles is at the ford of Xanthus when he divides the opposing forces.
“when they came to the ford of the full-flowing river Xanthus, begotten of immortal Jove, Achilles cut their forces in two”
Achilles splits the Trojan forces and chases one half panic-stricken across the plain toward the city.
“Achilles cut their forces in two: one half he chased over the plain towards the city by the same way that the Achaeans had taken when flying panic-stricken on the preceding day with Hector in full triumph; this way did they fly pell-mell”
Juno sends a thick mist before the fleeing Trojans to impede them.
“Juno sent down a thick mist in front of them to stay them.”
The Trojans flee pell-mell toward the city or are hemmed into the river, where they swim amid cries and whirling eddies.
“one half he chased over the plain towards the city by the same way that the Achaeans had taken when flying panic-stricken on the preceding day with Hector in full triumph; this way did they fly pell-mell, and Juno sent down a thick mist in front of them to stay them. The other half were hemmed in by the deep silver-eddying stream, and fell into it with a great uproar. The waters resounded, and the banks rang again, as they swam hither and thither with loud cries amid the whirling eddies.”
Xanthus is a full-flowing, deep, silver-eddying river.
“full-flowing river Xanthus, begotten of immortal Jove, Achilles cut their forces in two: one half he chased over the plain towards the city by the same way that the Achaeans had taken when flying panic-stricken on the preceding day with Hector in full triumph; this way did they fly pell-mell, and Juno sent down a thick mist in front of them to stay them. The other half were hemmed in by the deep silver-eddying stream”
At the ford of Xanthus, Achilles divides the routed Trojans, chasing one group toward the city under a mist sent by Juno while the other struggles amid the river's eddies like locusts driven into water by fire.
