The Battle of Mustafar was a small-scale battle in terms of size but a major battle in taking the Outer Rim. Mustafar was a needed planet with many resources the Mandalorians needed to keep the war effort going. The planet was controlled mostly by a smuggling group called the Nail Gonun. They used the minerals gathered to aid in their operations and trade. The battle was a complete success by the Mandalorians, causing the Republic to look at the Mandalorian conquest of the Outer Rim and do something about it.
