his countrymen, but Achilles coldly rejoins the Greeks will have to
defend themselves as he is about to depart. Such is his resentment
that he refuses to forgive Agamemnon, although his aged tutor urges
him to be brave enough to conquer himself. Most reluctantly therefore

_Book X._ Exhausted by the day's efforts, most of the Greeks have
fallen asleep, when Agamemnon, after conversing for a while with
Menelaus, arouses Nestor, Ulysses, and Diomedes to inspect their
posts. It is in the course of these rounds that Nestor suggests one of
their number steal into the Trojan camp to discover their plans. This
suggestion is eagerly seized by Diomedes and Ulysses, who, on their
way to the enemy's camp, encounter Dolon, a Trojan spy, who is coming
to find out what they are planning. Crouching among the corpses,
Diomedes and Ulysses capture this man, from whom they wring all the
information they require, together with exact directions to find the
steeds of Rhesus. To secure this prize, Ulysses and Diomedes steal
into the Trojan camp, where, after slaying a few sleepers, they
capture the steeds and escape in safety, thanks to Minerva's aid. On
seeing his friends emerge from the gloom with so glorious a prize,
Nestor, who has been anxiously watching, expresses great joy, and
invites his companions to refresh themselves after their exertions.
