Operation: BACKBURN

Operation: BACKBURN was an ONI-led operation against the Covenant Empire. 
== Prelude ==
After Circinius IV was glassed on April 26, 2526; the Fleet Master of the First Fleet of Glorious Consequence arrived in the system as he suspected that Forerunner tech may be on the planet as well as suspected the UNSC will try to return to search for possible survivors. 
With permission the Fleet Master took his entire fleet to the planet and hired a Yonhet to conduct a search on the planet. Several scouts from ONI identified the Covenant vessels around the planet's orbit and ONI concluded that the flagship may have vital information due to it staying back.
== the Operation ==
David-049 and his team ambushed a Type-25 Troop Carrier and forced the remaining unggoy at the gunpoint to fly the vessel over to the Indomitable Faith. David executed the Unggoy before they exited onto the ship and hid the bodies in a storage room. David combined a block of MX-8 with a plasma grenade and hid it behind the Unggoy.
They managed to maintain some stealth as they eliminated a small number of Covenant forces before entering the Hangar Bay. David managed to incapacitate a couple of unaware Sangheili, however, David's teammate Luna was discovered by the Yonhet that was on-board. Luna managed to stop him from calling out to the covenant forces by shooting him in the throat with her suppressed weapon, but he proceeded to fall backwards and landed in front of a group of Sangheili. Luna and David's other teammate Axle are killed in the ensuing battle that resulted. 
They proceeded to fight through the covenant forces and made their way to the Control room while eliminating the Covenant forces. David's remaining teammate Meredith Keyes proceeded to download 52% of the data before David decided to call the operation and declare it compromised. Meredith and David managed to fight their way back to the hangar and proceeded to force a couple of Unggoy to fly them out of the ship.
The covenant gave chase in Type-27 Banshees and Kai-Pattern Seraphs, however, the Unggoy managed to evade the attacks. David ordered one of the Unggoy off and ordered the other to show him how to fly the aircraft. The Unggoy complied as Meredith kept her weapon on the other Unggoy. She binded the other Unggoy to a part of the Spirit while keeping any of the weapons away from it before keeping her weapon aimed at the remaining Unggoy.
They use one of Circinius IV's moon to evade as they managed escape sight of the Seraphs and Banshees long enough for David and Meredith to bail from Spirit and hide from in a crater with the Unggoy as the Spirit was finally destroyed. One of ONI's stealth craft arrived and recovered them before leaving the area.
== Aftermath ==
ONI released information regarding the operation as the data and information that was collected was on the Kigyar, Unggoy, and Yonhet along with details referring their homeworlds and a rough detail on their biology. The First Fleet of Glorious Consequence remained in the system for another few more months before it was called away.
The Fleet was encountered once again in 2527 during Battle of Ephyra which resulted in the destruction of the Indomitable Faith and the strategic defeat of the First Fleet of Glorious Consequence.
