The Achaians are forced to take refuge behind their wall while the Trojans continue their brutal assault. But the Trojans soon discover that they are unable to cross the Achaian trench in their chariots, so they attack on foot. Much bloody combat ensues.
Then suddenly an eagle with a serpent in its talons flies over the Trojan army; Poulydamas, a Trojan commander, interprets this as a bad omen and asks Hektor to fall back, but the commander refuses. The attack continues and after several attempts, the Achaian wall is broken. Forcing open one of the gates with a large stone, Hektor and his men storm inside. The Achaians retreat in panic and take refuge among their ships.
Zeus has brought Hektor and the Trojans as far as the Achaian ships, so now he relaxes and turns his attention to other matters. Poseidon takes advantage of Zeus’ lapse of attention to come to the aid of the Achaians and, disguised as Kalchas, he moves among the Achaian ranks, encouraging them to continue fighting.
While the violent battle continues, old Nestor seeks out Agamemnon, Diomedes, and Odysseus, all three of whom are wounded. Nestor wants to devise a plan of action. Agamemnon is certain that the defeat of the Achaian army has been willed by heaven, and he can think only of having the troops retreat and board their ships, escaping by sea. Odysseus points out that this is not only dishonorable but that it would be extremely dangerous. It would be very difficult, he says, to launch and board their ships while under attack. To do this may make a Trojan victory even easier. The leaders then decide to go among the ranks and encourage their men.
From Olympos, Hera notices how Poseidon, the sea god, is trying to aid the Achaians, and so she makes plans to occupy Zeus so that Poseidon will have even more opportunity to help the besieged Achaians. Dressing in her finest garments and borrowing the magic girdle of Aphrodite, Hera flies off to Mount Ida, where Zeus is sitting. Her husband is overwhelmed by her charms, and Hera finds it easy to seduce him. As prearranged, the God of Sleep casts a spell over Zeus.
