Chapter 5 represents the fifth installment of the Star Wars: Clone Wars animated series. It also holds the position of the fifth episode within both Season One and Volume One. Genndy Tartakovsky served as the director for this episode, which was initially broadcast on Cartoon Network on November 13, 2003.
Yoda, through a narration, details the situation on the planet Mon Calamari. He explains that the planet's population is divided between two native species: the Mon Calamari, who are loyal to the Galactic Republic, and the Quarren, who have aligned themselves with the Confederacy of Independent Systems. The Quarren have established a Separatist-supporting government known as the Quarren Isolation League and have seized control of the world.
This narration is revealed to be a hologram transmission from Yoda to Jedi Master Kit Fisto, who is located on the bridge of his Acclamator-class assault ship. Yoda instructs Fisto to assist the Calamari in reclaiming their planet for the Republic.
The fleet of Acclamator ships, carrying Fisto's forces, arrives at Mon Calamari and floats on its expansive ocean. The aquatic Jedi Master, Fisto, dives into the water first, followed by several units of Kit Fisto's SCUBA troopers.
The Battle of Mon Calamari commences as the Republic forces face attacks from Manta droid subfighters, Sub Carriers, and Mini-subs, as well as Quarren and battle droid forces. The Mon Calamari Knights join the Republic's forces, providing reinforcement.
Difficulties arise for Kit Fisto when the Quarren deploy their Crab cannon, which destroys several of his floating Acclamators. With the help of the Knights and his mastery of the Force, the cannon is initially severely damaged and then pushed over the edge of a deep underwater chasm. This shifts the momentum of the battle in favor of the Republic.
