As in Hesiod's account, Rhea saved Zeus from being swallowed by Cronus, and Zeus was eventually able to free his siblings, and together they waged war against the Titans. According to Apollodorus, in the tenth year of that war, Zeus learned from Gaia, that he would be victorious if he had the Hundred-Handers and the Cyclopes as allies. So Zeus slew their warder Campe (a detail not found in Hesiod) and released them, and in addition to giving Zeus his thunderbolt (as in Hesiod), the Cyclopes also gave Poseidon his trident, and Hades a helmet (presumably the same cap of invisibility which Athena borrowed in the "Iliad"), and "with these weapons the gods overcame the Titans".
