"And yet, still you fail."

The New Phoenix Incident,[3] or the Fall of New Phoenix,[4] was a brief engagement fought between the United Nations Space Command (UNSC) and the Ur-Didact and his Promethean forces in close proximity to Earth on July 25, 2557.[4][2]

Background[edit]

Having retrieved the Composer from Ivanoff Station, the Didact set out to attack Earth in his ship, Mantle's Approach. The Didact was unaware, however, that John-117 and Cortana, in a Broadsword fighter, had managed to breach the ship's shields and make the slipspace journey along with it.[5]

Space combat[edit]

John-117: "The Didact's got the Composer. We're in a Broadsword carrying a HAVOK-grade payload, on approach to deliver it."
Thomas Lasky: "Let's see if we can grease the wheels for you. All ships! Prepare to engage!"
— John-117 conversing with Lasky as the Didact's ship approaches Earth.[2]

As the ship emerged near Earth, the UNSC Home Fleet was mustered in Earth's defense; including the UNSC Infinity, now under the command of Thomas Lasky. Despite this preparation, the fleet's efforts were rendered useless by the advanced technology of the Didact's ship. Earth's orbital defense grid went into Red Alert, but even the orbital defense platforms proved ineffective. Hunting for the Composer aboard Mantle's Approach, John-117 and Cortana proceeded to destroy the turrets defending the ship's main weapon, allowing the Infinity to fire upon the Didact's ship to open a hole for the Master Chief's Broadsword. However, the interior defenses made the passage too narrow for the fighter to pass through and caused it to crash, forcing the Chief and Cortana to carry their HAVOK payload to the Composer on foot.[2]

On the ground[edit]

As John-117 and Cortana reached the Composer, the Didact activated the device, composing seven million people in New Phoenix, a major population center in the United Republic of North America. Among the people composed by this beam were Gabriel Thorne's grandmother Ayres of the New Phoenix Philharmonic[4] as well as artist Anaru Kawiti.[6]
