The Battle of Manhattan was the major battle that was the climactic final battle of the Second Titan War. It was also the largest land battle of the Second Titan War in terms of numbers of troops deployed on both sides. The battle began on August 16, 2009 and ended August 18, 2009.

It began with @Morpheus putting the entire island of @Manhattan to sleep. The @Titan Army covered Manhattan in layers of magic. The cars on the New Jersey highway seemed to be moving at one mile per hour due to Kronos slowing time. Also, @Hecate may have been helping by using magic, because it seemed like all the drivers were getting a subconscious message to turn away from any Manhattan exits. Since the wind gods (@Aeolus, @Boreas, Notus, Zephyros and Eurus) would keep @Kronos' forces away from @Olympus by the air, and the spirits of the Hudson and East River drowned all forces on the water, Kronos was forced to try a ground assault.

Forces

Titans

Kronos sends a fleet of speedboats which race to Manhattan by the Long Island Sound. Each speedboat was packed with demigods that were against the gods in full Greek armor. At the back of the lead boat was the battle flag of Kronos.

Also, a Staten Island Ferry was plowing through the waves near Ellis Island, which carried @Scythian Dracanae and a whole pack of @Hellhounds. Swimming in front of them was a pack of @Telekhines.

In the Lincoln Tunnel, there were a hundred assorted monsters marching past the lanes of stopped traffic. Giants with clubs, @Cyclops, fire-spitting dragons and a World War II-era M4 Sherman tank.

Demigods

@Percy Jackson divides the campers to defend different sections.

• @Michael Yew takes the Apollo cabin to the @Williamsburg Bridge.

• @Katie Gardner takes the Demeter cabin to the Brooklyn-Battery Tunnel.

• @Connor Stoll takes half of the Hermes cabin to the Manhattan Bridge.

• @Travis Stoll takes the other half of the Hermes cabin to cover the Brooklyn Bridge.

• @Silena Beauregard takes the Aphrodite cabin to the @Queens-Midtown Tunnel. Fifth Avenue is on the way and one of Silena's sisters suggests using Givenchy, perfume and accessories against the monsters. It is unknown whether it was effective.

• @Malcolm Pace takes the Athena cabin to the 59th Street Bridge. Originally Percy had called @Clarisse La Rue's name, but the Ares cabin was at camp sitting out of the war (because Clarisse and Michael Yew had an argument over the camp's only war chariot stolen from one of the unknown quests mentioned in the series).

• @Jake Mason takes the Hephaestus and Dionysus Cabins to the Holland Tunnel.

• @Thalia Grace takes the @Hunters of Artemis to the Lincoln Tunnel, a position that the campers could not defend due to lack of people. Clarisse was upset over losing the war chariot to Michael Yew of the Apollo cabin, so she refused to fight in the battle.

• Percy and @Annabeth Chase take care of the boats by making a deal with the rivers, giving them each half a sand dollar.

• On the second day of the battle, Silena disguised as Clarisse takes the Ares cabin members into battle, but is ultimately killed by a @Drakon. After her death, Clarisse takes back control over her cabin and destroys the drakon, gaining the blessing of @Ares in the process which makes her invincible for a short time.

• Percy Jackson and Annabeth Chase act as backup for any of the positions unable to hold their ground at any time of the battle.

• @Will Solace and a few of his cabin members heal wounded cabin members in the battle if needed.

The Beginning

Percy sends troops out to all entrances, while Annabeth executes Daedalus Twenty-Three (by a suggestion from @Athena) to wake up the automatons in the disguise of statues inside the city to protect Olympus. Then Percy goes to meet the Hudson River spirit and East River Spirits. The gods ignore him at first, but Percy decides to spend his sand dollar as a bribe to the two river gods. After half is given to each, the two gods make sure nothing enters the rivers and sink the boats carrying the enemies. Percy and Annabeth then leave, heading toward the Apollo campers fending off some of the enemy army led by the @Minotaur.

The Minotaur, angered by seeing Percy once again (having been beaten by a twelve year old Percy in the past), charges him. A battle between the two unfolds, leaving Percy the winner. Percy then kills off most of the monsters because he is nearly indestructible, having received the so-called Curse of Achilles by swimming in the @River Styx. More enemies show up, along with @Ethan Nakamura, the son of @Nemesis, who stabs Annabeth in the shoulder while unintentionally aiming for Percy's Achilles' heel. Blackjack takes Annabeth away somewhere safe so she can recover, and Kronos shows up and begins to cross the Williamsburg Bridge, but is stopped when Percy floods and destroys the bridge at Michael Yew's suggestion. The bridge is destroyed, but Michael is nowhere to be found and is assumed dead. Percy gets a phone call and is told that Annabeth is severely hurt.

When he arrives, Will Solace, one of Apollo's sons, tries to heal her. Silena Beauregard decides that since she is no good at fighting, she should go and try to convince Clarisse to bring the Ares' cabin and fight, who chose not to fight because the Apollo's cabin received a chariot they thought they should have, similar to Achilles not fighting in the Trojan War because Briseis was taken from him. Grover shows up, telling Percy that he's convinced some nature spirits to fight for them and Olympus and Thalia arrives with the Hunters of Artemis to help defend Olympus from Kronos and his @Titan Army.

Afterwards, Percy sleeps and dreams of @Nico di Angelo. Nico tries to talk to his mother, Maria di Angelo, but Bianca di Angelo comes and tries to convince him not to. Nico ignores her and continues to try and reach his mother. Instead, he finds a horrible memory of his early childhood in which his mother is killed by @Zeus, and because of his grudge against the Great Prophecy, Hades puts a curse on a young girl, who is known as the mummy in @Big House Attic at @Camp Half-Blood, that the Oracle, as long as Hades' children remain outcasts, she will never be able to take another mortal form and will instead rot away. Then, he dreams of @Rachel Elizabeth Dare at a beach. She writes his name in the sand, then convinces her dad to take her home because she believes Percy is in danger, promising to go to finishing school as a trade-off.

Percy is then woken by Thalia, who says a Titan wants to speak with him. It turns out to be @Prometheus. He tries to get Percy to believe there is no hope of Percy beating Kronos but does not succeed. He then gives him @Pandora's Box, which conceals @Hope Fragments, and instructs him to use it as a signal of surrender if need be. Percy then has a vision of Luke talking with Hermes when he was on the run with Thalia and Annabeth.
