Battle of Dxun A massive battle on Dxun was one of the last battles of the Mandalorian Wars prior to the final confrontation between Republic and Mandalorian forces at Malachor V . The siege took place at a critical stage of the conflict and many of those who fought for the Republic believed it would determine the ultimate outcome of the war . In the years leading up to the battle , the Mandalorian Neo - Crusaders had seen their vast territorial gains relentlessly rolled back by the Republic forces commanded by the Jedi Knight Revan . The tide of the war had turned in favor of the Republic , yet the Mandalorian fastness in the Japrael system remained intact . Before the Republic could bring the fight to the Mandalorians along the Outer Rim , their enemies ' Inner Rim headquarters on Dxun had to be taken . Revan ordered his forces to launch a large - scale assault on the Mandalorian - held world , an attack that would prove to be very costly for the Republic . The Mandalorians were deeply entrenched after decades of fortifying the moon . They were well defended by hidden minefields , traps , anti - air turrets , and the ferocious beasts of the jungle itself . As a result , the battle was one of the bloodiest in the entire war . Once it was over , the bodies of Republic soldiers and the hulks of fallen spacecraft littered the jungle floor . According to the Mandalorians , the Republic " lost many of their forces taking Dxun . For every Mandalorian soldier who fell , the Republic paid with ten of theirs . " Jedi General Meetra Surik , who would come to be known as the " Jedi Exile " , took part in the battle . Revan ' s battle plan called for hundreds of small - unit feints aimed at probing the Mandalorian line for exploitable weaknesses . Trusting in her commander ' s complex plan , Surik carried out her orders even though her command was scattered and had been depleted to a quarter of its full strength . The majority of her remaining soldiers were lost during a desperate charge across a minefield as they attempted to strike at the Mandalorian emplacements . The Mandalorians refused to give ground and it took the Republic months of continuous , bloody assaults to dig them out of their fortifications . Late in the battle , Mandalore the Ultimate realized that the Republic would carry the day and he ordered his forces to abandon their headquarters . When the Republic military finally attacked the fortress , its walls were manned only by a few volunteers who had been allowed to stay and fight . In the end , Revan ' s forces were victorious . They retook Onderon and its companion moon Dxun , events which would set the stage for the next phase of the war . According to Canderous Ordo " in the last months before Dxun fell , the old Mandalore knew that Revan and the Republic were gaining the upper hand . " He ordered the best Mandalorian engineers " to hide caches of weapons and munitions throughout the moon , safely away from enemy hands . " The Republic later attempted to search out and open these caches , but their efforts were stymied by the traps and other surprises that Mandalore ' s men had left behind . A decade later these weapons and supply caches would become invaluable to the Mandalorians serving Canderous — who had become the new Mandalore .
