What did Zeus do to punish the titans?

Some stories say that all of the Titans were bound in Tartarus. Others say that all except Cronus were bound. Cronus was given fermented honey (otherwise known as mead) and once passed out from drink, taken to the cave of Nyx (personification of night) and left to dream for all eternity.

The latter represents that Cronus (personification of Life) could not be held within the confines of the Underworld (because doing so would end all life).
