The assault on Arkania was a battle of the Yuuzhan Vong War in 27 ABY, when the Wild Knights attempted to capture a Yuuzhan Vong yammosk for study while simultaneously disrupting the Yuuzhan Vong plan to invade Arkania. After consulting with Vaecta and Vergere, Tsavong Lah executed the commanders who let the Jedi escape before launching a half-hearted attack on Arkania and withdrawing, to appease Yun-Yammka. Following the battle, Arkania would be conquered by the Yuuzhan Vong.
