What did Helios do to Odysseus' men? What reason did he have?

After Odysseus men both eat and sacrifice the oxen they weren't to touch, Lord Helios asks Zeus to punish them. After the crew feasts for six days, they set sail. Zeus whips up a storm for punishment and shoots a thunderbolt at the ship, wrecking it. The men fall in the water and drown, and Odysseus grabs on to floating pieces of the ship. He drifts back to Charybdis, from which he barely escapes.
