Attack on the Princess Andromeda

The Battle of the Princess Andromeda was a battle in the Second Olympian War.

The Battle
Kronos and the Princess Andromeda made way for an assault on Manhattan, but Percy Jackson and Charles Beckendorf were sent to stop it. Percy and Beckendorf flew on Blackjack the Pegasus and arrived undetected on the ship. Percy and Beckendorf made way to the engine room. Percy had to eliminate several Telekhines and lead the rest away from Beckendorf, who was sabotaging the engine room. Percy fought a giant crab but soon was surrounded by monsters and Kronos. Ethan Nakamura led giants to capture Beckendorf. Percy fought against Kronos but was defeated, nearly dying in the process. Beckendorf had however already primed the Greek Fire in the engine room. Beckendorf sacrificed himself to save Percy by blowing the ship up with the detonator while Percy escaped.

Aftermath
Percy floats to Poseidon's Kingdom (he sank to it while he was unconscious) and was told that he had to go back to camp. Percy feels guilty about leaving Beckendorf, but his death was not in vain: It delayed Kronos, giving the Camp more time to prepare and also destroyed an army of monsters.
