According to the "Invocation" of "Book One" of "The Odyssey," Odysseus' men do not reach home because?

He came to see
many people's cities, where he learned their customs,
while on the sea his spirit suffered many torments,
as he fought to save his life and lead his comrades home.
But though he wanted to, he could not rescue them—
they all died from their own stupidity, the fools.
They feasted on the cattle of Hyperion,
god of the sun—that's why he snatched away their chance 10
of getting home someday.

The first book of the Odyssey opens with what might be considered a type of trial of Odysseus in front of the gods.  This invocation brings to light that while he was a great warrior, leading his men over the warriors from Troy, he was vain and boastful in his victory.  His revelry with his men offended the gods.  His battles in Troy and his destruction of the Cyclops angered Poseidon, god of the Sea.  The fact that Odysseu's men engaged in offensive and hubris filled actions angered the gods greatly, for hubris (excessive pride) in humans had always been frowned upon by the Greek Gods.  Hence, while they might have been victorious, Odysseus' men were punished with their inability to return home.  Ironically enough, the soldiers of Troy, who lost, were allowed to return home as supposed reward for their humility.
