While Patroklos assists Eurypylos, the battle continues.
The Achaians have now retreated inside their wall.
The poet tells us how, one day, the gods will destroy the wall—for it was built without the proper sacrifices. (It's like they never applied for a building permit.)
Now the Trojans are wondering how to cross the ditch encircling the wall.
A Trojan warrior, Poulydamas, suggests they dismount and make a massive attack on foot. Hektor agrees.
The only one who doesn't is Asios, who madly tries to drive his chariot through the gates before the Achaians close them.
Asios doesn't succeed, in part because of the brave defensive fighting of Polypoites and Leonteus, two staunch members of tribe of the Lapithai (an Achaian ally).
A furious battle now erupts at this gate.
Just when it looks like the Trojans are about the breach the wall, an eagle flies overhead, on the left (this was viewed as unlucky), and carrying a snake. The snake is still alive, and keeps biting the eagle until it finally lets it go.
The Trojans think this looks bad for them, and hesitate.
Poulydamas urges Hektor to respect the sign and not attack the Achaian ships.
Hektor sharply rebukes him and calls him a coward.
Led by Hektor, the Trojans press on and start trying to tear down the wall.
So far, the spirited resistance of the two Aiases prevents them from being wholly successful.
Now Sarpedon encourages his cousin Glaukos to join him in leading a renewed assault.
The Achaian warrior Menestheus, who is manning the defenses at that part of the wall, sends a message to the two Aiases and Teukros to come give him some backup.
When they arrive, they immediately start killing Trojans. Teukros injures Glaukos with an arrow, but Zeus prevents his son Sarpedon from receiving any mortal injury.
Now is Sarpedon's time to shine. With his bare hands, he tears a huge hole in the wall and encourages the Trojans to come in after him.
The result, however, is a deadlocked battle in the gap in the wall: neither army can advance, yet neither can retreat. Many men are killed.
Hektor, however, releases the pressure valve. How? Well, he picks up a giant rock and hurls it at the gates of the wall, shattering them.
Then he rushes in alone.
Trojans start streaming in through the gates and also over the wall. Things are looking bad for the Achaians.
