The Battle Group of Yun-Yammka was one of the five battle groups under the Yuuzhan Vong during the Battle of Ebaq 9.
When the Yuuzhan Vong arrived at Ebaq 9, Warmaster Tsavong Lah ordered the Battle Group to attack the squadron under the command of General Keyan Farlander. However, as the battle turned against the Yuuzhan Vong, Lah decided to sacrifice the Battle Group to allow the rest of the fleet to escape. Not one member of the Battle Group offered protest. When Lah ordered the rest to retreat, the Battle Group of Yun-Yammka was still too far in the Treskov system's gravity well to escape, and each vessel was destroyed.
