The Second Battle of Bilbringi, known in the planning stages as Operation Trinity, was a military operation fought near the end of the Yuuzhan Vong War, involving the Galactic Federation of Free Alliances and the Imperial Remnant, an associate state.
The Bilbringi system was captured by the Yuuzhan Vong invaders in 27 ABY.
The Galactic Federation of Free Alliances, in an effort to cut off Coruscant from the major systems in the Inner and Mid Rims, launched three major attacks within a month or so of time—one at Duro, another at Fondor, and the last at Bilbringi. The attack was orchestrated by Supreme Commander Sien Sovv and three of his other commanders: Admiral Traest Kre'fey, General Wedge Antilles and General Garm Bel Iblis.
Dubbed as Operation Trinity, the task force was divided into three groups: Alpha Fleet led by Antilles took the point, supported by Beta Fleet led by Grand Admiral Gilad Pellaeon, and Gamma Fleet led by Kre'fey. The first point of the operation was for Antilles to enter the system and scout for any weakness in the enemy fleet. Then he was to send the most tactically suitable entry points to the other two fleets.
However, just before Antilles' fleet went in, the Yuuzhan Vong released their latest creation, the mabugat kan, which brought down several HoloNet relay stations. Since the entire operation depended on HoloNet transmissions to coordinate their attack, Antilles was unable to call in the other fleets for help. His fleet was trapped in a system full of hostiles, and the formation took heavy losses.
Many of his ships were destroyed in the battle, most notably the Interdictor Cruiser Memory of Ithor commanded by General Pash Cracken. Antilles did inflict heavy casualties to the Yuuzhan Vong forces, destroying the Interdictors and several other vessels.
Antilles' fleet narrowly escaped being completely obliterated by the Yuuzhan Vong. Only an order by Antilles to reduce the Mon Mothmas shields saved the fleet. The Yuuzhan Vong retreated, thinking that the Star Destroyer's main reactor was going critical; along with the timely intervention of a cloaked Golan II Space Defense SpaceGun commandeered by Han Solo, it allowed Mon Mothma and the remaining vessels of Alpha Fleet to retreat to Mon Calamari.
Antilles later met up with Pellaeon's fleet after the battle was over.
Many of the captured Alliance soldiers were taken by the Yuuzhan Vong to Selvaris.
The Battle of Bilbringi makes its first appearance in The New Jedi Order: The Final Prophecy by Greg Keyes, in which it forms one of two major plotlines.
Fleet Group Alpha, the battle group commanded by Wedge Antilles, is described as comprising less than a third of the Yuuzhan Vong force in the system, yet with at least seven capital ships commanded by Antilles and fourteen in the Yuuzhan Vong command, this sizing ratio is inaccurate.
