Ebaq 9 is a moon of the gas giant Ebaq in the deep core of the Star Wars galaxy. It was originally mined for its heavy metals by the Empire, but it was converted to a military base by the New Republic to bait the Yuuzhan Vong fleet, where they were destroyed by the New Republic.
The Battle of Ebaq 9 took place during a crucial time in the war with the Yuuzhan Vong. Retired Admiral Ackbar, hero of the Galactic Civil War, developed a plan to turn the war in the favor of the New Republic. The commander of the Yuuzhan Vong fleets, Warmaster Tsavong Lah, was obsessed with destroying the Jedi. Ackbar used the old base on Ebaq 9 to install a force of Jedi, including Jaina Solo. Using deception and feeding false information to Yuuzhan Vong spies, operating under Nom Anor, the New Republic lured Tsavong Lah to attack.
The warmaster brought thousands of ships into the system. He was exultant when his Voxyn howled, indicating there actually were Jedi on Ebaq 9. Once the Yuuzhan Vong fleet had entered the system, other Republic ships moved in and planted an interdiction field generator, along with tens of thousands of mines, along the route of which the Yuuzhan Vong would have to take out of the system. Then, from secret hyperspace routes deep in the galactic core, hundreds of Republic ships jumped into the system, attacking the Yuuzhan Vong from all directions.
Tsavong Lah, realising he had been baited and lured into a trap, ordered a large portion of his forces to retreat. Knowing his reputation was destroyed and his honor lost by the looming defeat, he kept part of his forces and prepared to fight to the death. Many of the retreating Yuuzhan Vong ships were destroyed by the minefields laid in their path of retreat.
With his remaining forces, Tsavong Lah pushed straight for Ebaq 9 after announcing a Jedi hunt, to which Jacen Solo responded. Once Tsavong Lah landed on the moon, he personally lead over ten thousand warriors in a ground attack through the tunnels. He eventually figured out that Jaina was on the planet, which was why Jacen decided to come, and decided to try to sacrifice the twins again so he could regain his honour.
Republic forces, led by General Garm Bel-Iblis, Admiral Traest Kre'fey, General Wedge Antilles, and Jedi Master Luke Skywalker, easily overwhelmed the remaining Yuuzhan Vong spaceships. During the chaos of the ground fighting, the Fosh Jedi, Vergere, stole an Alliance A-Wing and crashed it into the moon, killing the Yuuzhan Vong attacking Jacen. The battle ended as Jaina Solo cut down Tsavong Lah in a brief duel among the thousands of Yuuzhan Vong corpses.
In many ways, the Battle of Ebaq 9 was a turning point in the war. It was one of the first times the Yuuzhan Vong had been so openly and decisively defeated.
