Battle Group of Yun-Yammka
this was one of the five primary Yuuzhan Vong naval forces which were deployed by the Warmaster, Tsavong Lah, to attack the New Republic base on Ebaq 9. This group was the first to attack the New Republic's forces, drawing initial fire and allowing the Battle Groups of Yun-Txiin and Yun-Q'aah to try and outflank the enemy. However, the reserve forces of the Republic pounced on the battle group, and Tsavong Lah was forced to use the Yun-Yammka battle group as a sacrifice. He ordered the group's warships into all-out attacks designed to disrupt the enemy, thereby giving the other battle groups a chance to survive. When the Yuuzhan Vong fleets were ordered to retreat, the Yun-Yammka group was too near Ebaq to make the jump into hyperspace. All ships in the Yun-Yammka fleet were destroyed by the New Republic.
