The Battle of Alsakan was the final battle of the Alsakan Crisis in 12,999 BBY between the Galactic Republic and the Alsakan Union. The battle began when the Republic launched an assault on Alsakan forces around the planet Alsakan, an assault which the Republic was able to defeat the Alsakan forces in. Upon their defeat, members of the Alsakan military collapsed the integrity of Xenvaer, the orbiting Alsakan city, while Republic forces were surrounding it, causing the city and a number of Republic vessels to crash into and devastate the planet.
