Official description
"When Anakin is forced to temporarily turn over command of his clone troopers to a new commander, the Jedi Pong Krell, tensions begin to run high as the clones are assigned with a very deadly mission to take the capital of Umbara."

Synopsis
Aboard their command ship, Anakin Skywalker and Obi-Wan Kenobi discuss their attack strategy against the Umbaran capital, which is defended by both Confederate and local Militia forces. Joined by Rex and Fives, Anakin prepares to repel enemy reinforcements striking against Obi-Wan’s joint attack with Jedi Masters Saesee Tiin and Pong Krell.

Amidst heavy flak fire, the Republic AT-RT forces manage to take out the Umbaran tanks, allowing the Transports to set down their load of clone troopers. But the assault is hampered by the planet’s natural murkiness and foggy conditions, as well as the local wildlife, one of which nearly claiming the lives of Fives and Hardcase, though Fives manages to kill it with a Thermal detonator. These adverse conditions allow the Umbarans to execute a sneak attack against Skywalker’s forces just as they are getting ready for their mission, forcing them to retreat. An airstrike by Master Krell saves them just in time, but then Krell approaches Anakin with a disconcerting message: Anakin is to return to Coruscant and meet Supreme Chancellor Palpatine, for reasons unknown. Reluctant to leave his troops in the midst of battle, Anakin nevertheless is forced to relinquish command over his troops to Master Krell and make the journey back to the Republic capital.

As soon as Skywalker departs, however, Krell adopts a very derisive, condescending stance towards the clone troopers, showing them no respect or consideration. His harsh determination to complete the mission at all costs, no matter what, gradually raises the ire of the clone troopers. When they reach the capital, Krell insists on a change in the attack plan, opting on a full frontal assault on the capital’s main road instead of a series of preemptive surprise attacks against the enemy’s defenses – a course which would expose them to heavy enemy attack, and as Rex feared, the battalion begins to run into enemy traps, with mines on the main road and an all-out ambush which claims the lives of many troopers. Rex orders his troopers to retreat in order to attain a more advantageous fighting position. Though frustrated by the clones for retreating, Krell ordered additional troopers and AT-RT drivers to save Rex and his men. After they managed to repel the natives, Krell immediately begins to criticize Rex for retreating and compromising his plans. Rex and Fives stand up to him, voicing their protests and pointing out that while they are aware of the importance of their mission, they are also concerned about the welfare of their men. Krell eventually gives Rex a dubious compliment, but before Rex and Fives have the time to contemplate Krell’s word more thoroughly, the Umbarans launch a counter-attack, forcing them to refocus on the battle...

Behind the scenes
In the episode, when General Krell scolds Captain Rex, he refers to him at "CT-7567," even though Rex is a captain and holds the designation CT-7567, per many sources. This same mistake is made when Fives stands up to General Krell, in which Krell addresses Fives as "ARC-5555," though Fives holds the designation CT-27-5555. Rex's Encyclopedia entry on StarWars.com later confirmed that his new designation is CT-7567.
