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.
– Homer
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."
