Second Assault on Mandalore (Second Civil War)

The Second assault on Mandalore, was the second battle on Mandalore, and the most violent of the two, that took place between the Sith and Mandalorian troops, and the chiss assault forces with the hired Magna mercenary group. The previous battle was the Assault on Polis Massa and the next was the Battle of Ankus.

Beginning
It started when the Sith and Mandalorian troops were stationed on the planet, and were in the process of building a large bunker, then the chiss, (along with the hired magna assault mercenaries) searched the planet out for any signs of life. Eventually, the Sith and Mandalorians detected them with motion sensors outside of their base, so, the large band of troops went out to destroy the threat. As they were coming closer, the Magna engineers picked them up on their lifeform scanners, and warned the chiss troops. As they were both heading towards each other, a large wave of blaster fire came from both sides killing many of the enemy troops.

The fight
During the middle of the battle (unknown to the enemy Sith and Mandalorians) the chiss had large transport walkers, similar to the AT-ATs used by the Imperials during the Galactic Civil War. They were equiped with heavy laser cannons, that easily took out the perimeter defenses of both the Sith and Mandalorians. But they weren't enough, the Sith had large speeders and rocket launchers, that easily took down the walkers. After this blow to the chiss' assault forces, the Magna mercenaries quickly charged on the Mandalorians, and in less then two hours, were completely wiped out by emplacement turrets and infantry. After this loss to the chiss' forces, they pulled back, firing at the enemy soldiers as much as they could, but were eventually surrounded and taken prisoner.

End
After the battle, the Sith and Mandalorians were victorious, and still had large numbers, they took all the remaining chiss prisoner, and eventually executed them. After this horrible defeat, the destroyed Magna mercenary group, only had a few members left; of the ones that weren't killed, were later absorbed into the chiss' remaining military legions on other planets.
