What did Odysseus men do that Odysseus had warned them not to?

Odysseus warned his men not to eat the cattle of the Sun God, HeliOS, while they were on the island of Thrinacia. Despite his warnings, the men, driven by hunger, killed and feasted on the sacred cattle. This act of disobedience led to dire consequences, as HeliOS sought revenge by asking Zeus to punish them, resulting in a storm that destroyed their ship and led to their deaths.
