But Achilles wept, and slipping away from his companions,
far apart, sat down on the beach of the heaving gray sea
and scanned the endless ocean.
The Iliad, Book 1, lines 413-415. Achilles becomes very emotional and cries when Briseis is taken away from him by Agamemnon’s men, even though she is a slave girl. This is partly out of rage that Agamemnon dishonored him, but also because he actually loves her. Later in Book 9 Achilles confesses: "I loved that woman with all my heart, though I won her like a trophy with my spear."
