A New Sith Adversary

Darth Sidious chastises Cody for his failure on Kashyyyk, and takes him off the assignment, instead ordering him to go get Sith Assassin Zen Kalab.

Palpatine tells Zen Kalab that his spies have told him that the Rebellion is sending troops to help Rico's Brigade on Kashyyyk, but their ships will be stopping on Alderaan to refuel. Kalab's mission is to strike at them there.

Battle Results
The Rebels take up defensive positions around their landed ship on a hill, and Zen and his elite troops attack from two angles, the right-side force led by Zen. Zen's troops engage the Rebels first, Zen himself charging forward before getting suppressed. The left side force engages, too, and the two armies soon stalemate, but the Rebel's defenses at the bottom of the hill fall, and those on the edges of the hill dwindle.

The left side group of Shadow Scout Troopers crests the hill, but comes under heavy fire, and are all but wiped out. Zen has his Shadow Scout Troopers spread out to surround the hill, but the battle again stalemates as the Rebels continue to hold their positions. A few Shadow Scout Troopers try to provide cover from back in the forest, but the Rebels are more than happy to return fire.

The Shadow Scout Troopers try to rush the hill, but get suppressed. Zen abruptly calls a retreat for his roughly 50 remaining men, while the Rebels continue on their journey with over half their army intact.

Trivia

 * The game crashed towards the end of the battle, so Daley decided that Zen called a retreat.
