Battle of Dxun

One of the final sieges of the Mandalorian Wars, prior to the final battle at Malachor V.

By the end of the war, the forces under Mandalore the Indomitable had seen their last several years' worth of territorial gains relentlessly rolled back by the Jedi forces under Revan, but their primary fastness in the Onderon system remained virtually impregnable to any forward Republic assault at that point in time. The main Mandalorian redoubts on the Dxun moon itself were of prime concern to the Jedi, for without first onquering them, the war would continue to drag on unceasingly.

In the last months before Dxun finally fell to Revan's forces (much later in the war -- circa 3,960 BSW4, according to the dialogue), the old Mandalore realized that Revan and the Republic were now in fact their superiors in combat. He ordered his best engineers to secrete weapons caches away throughout the jungle moon, safe from the hands of their enemies. The Republic later attempted to search them out, but encountered the little..."presents"...Mandalore's men left behind for them.

The battles to retake Onderon and Dxun were some of the bloodiest in the entire war, with the Mandalorians so deeply entrenched that it took the Republic months to dig them out of their fortifications. By this point, the Republic knew that Onderon's fate would be decided on its jungle moon, not the planet itself.

A datapad recovered from the skeletal corpse of a Republic transport pilot reveals crucial details concerning the Republic's final siege of Dxun during the Mandalorian Wars: Revan insistently demanded that they take Dxun, and committed a wing of military droid carriers to fly in low, and drop their payloads onto the jungle moon. Once the droids hit dirtside, they were to seek out the Mandalorian bases and pave the way for the main Republic ground-force waves...and the Jedi. They were expecting quite heavy resistance from the entrenched enemy positions, with some fear that if the droids could not take out the anti-air turrets, the mission was going to end up becoming one of the briefer ones in the annals of warfare.

In the end, Revan's forces were victorious, reconqering both Onderon and its companion moon, setting the stage for the next phase of the war and the final battle at Malachor V.
