Patroclus (in pursuance of the request of Nestor in the eleventh book) entreats Achilles to suffer him to go to the assistance of the Greeks with Achilles’ troops and armour. He agrees to it, but at the same time charges him to content himself with rescuing the fleet, without farther pursuit of the enemy. The armour, horses, soldiers, and officers of Achilles are described. Achilles offers a libation for the success of his friend, after which Patroclus leads the Myrmidons to battle. The Trojans, at the sight of Patroclus in Achilles’ armour, taking him for that hero, are cast into the utmost consternation: he beats them off from the vessels, Hector himself flies, Sarpedon is killed, though Jupiter was averse to his fate. Several other particulars of the battle are described; in the heat of which, Patroclus, neglecting the orders of Achilles, pursues the foe to the walls of Troy; where Apollo repulses and disarms him. Euphorbus wounds him, and Hector kills him: which concludes the book.
