Operation: VERTICAL UMBRAGE was a boarding mission to destroy Covenant cruiser Panom's Canticle during the Requiem Campaign, on February 14, 2558. It was conducted by the Spartans-IVs of the UNSC Fireteam Shadow.[1][2]


During the Requiem campaign in February 2558, Promethean forces allied with Jul 'Mdama's Covenant launched an attack on "The Refuge", where the science team from UNSC Infinity were studying the Forerunner shield world's local slipspace translocation technology. Fireteam Crimson, stationed at "The Refuge", identified and disabled the device that enabled the Prometheans to teleport into the facility.[3] Crimson remained at the facility until additional UNSC forces arrived to secure the location. However, upon the arrival of Warbird Company, the Panom's Canticle arrived and launched a second assault on "The Refuge".[2] Ryn 'Alun, the Panom's Canticle's shipmaster, was tasked with repelling the UNSC forces at "The Refuge".[1] For this, he deployed his personal special unit, the Silent Blade.[2]

Crimson was immediately occupied with repelling ground forces, and unable to address the source of the attack.[2] Meanwhile, Fireteam Shadow—composed of Spartans Horatio Fry, Nina Kovan, Bonita Stone, and Jason Kidman—were dispatched to another location on the shield world to neutralize a Covenant firebase established two days earlier, and serving to produce fighters. In the middle of the operation, Fry was contacted by Crimson's handler Jared Miller, who reassigned Fireteam Shadow on a priority operation to destroy the cruiser Panom's Canticle at "The Refuge". Being too far from their Pelican, Shadow stole a Phantom from the firebase's summit site to quickly respond to Miller's request.[1]


"Shadow Leader to Spartan Miller. Sorry for the delay, Sir. We're meeting heavy resistance in the cruiser. Seems like they don't want their spaceship blown up."
— Horatio Fry to Miller.[2]

Aboard the stolen Phantom, Fireteam Shadow took advantage of the surprise to rush into the Panom's Canticle hangar before the shields were activated by the crew. Shipmaster 'Alun, certain that the intruders would attack the reactor core, led several other Sangheili to the reactor room.[1]

Shadow made rapid progress through the ship, but encountered heavy resistance as the Spartans approached the core. While Fry, Kovan, and Kidman cleared out the last Covenant troops in the hallway leading to the main reactor room, Stone had already used her active camouflage to infiltrate the chamber. When the three Spartans burst into the hall, they were faced with 'Alun, who was accompanied by a dozen Silent Blade Sangheili. The two parties also engaged in combat and Fry was pinned to the ground by 'Alun, who nearly killed him with his energy sword, but Stone, still camouflaged, intervened and threw the Sangheili aside.[1]

Kovan armed herself with the Selene's Lance—an enhanced variant of the M6/E Spartan Laser—and fired at the core five times, causing the reactor to overload. 'Alun ordered his crew to abandon ship; Stone made an attempt to intercept the fleeing shipmaster, killing two Sangheili, but 'Alun escaped. Meanwhile, Kidman located a nearby drop pod bay, and led his squad mates to their means of egress before the cruiser's impending explosion.[1]


All members of Fireteam Shadow escaped onboard a Gloto'kef-pattern assault carapace from the destruction of Panom's Canticle, which then crashed into the surrounding jungle. Ryn 'Alun also survived, now driven by a desire for vengeance against the Spartans of Fireteam Shadow.[1][2]
