The Battle of Bandomeer was a battle in the Bothan War. This battle was the first battle to feature the Mandalorians, who had just announced their alliance with the Core Systems Alliance. Mandalorian forces were overwhelmed by the Muun forces fighting for Darth Naarin. Despite a brave effort by those defending the planet, it fell to the Muuns.
One interesting note about the battle was that Naarin's invasion of Mandalorian Space was executed without the approval of Muun Federation leaders. However, after the battle, they agreed to support the campaign. Naarin and Torrent launched the attack to build support for them in the eyes of the Muun military. The goal was to get enough support so that when the time came to usurp the current Muun government, the military would be behind them and not the leaders that had been replaced.
