"Chapter 4" is the fourth episode of the Star Wars: Clone Wars animated television series, and the fourth episode in Season One and Volume One. Directed by Genndy Tartakovsky, the episode originally aired on Cartoon Network on November 12, 2003.
As the Galactic Republic forces advance, panic spreads throughout the Banking Clan headquarters. San Hill angrily asks the Separatist commander, Durge, why Dooku bothered appointing him to command when he hasn't done anything. Durge's reply consists of choking San Hill.
On the outskirts of Harnaidan, clone troopers report to Obi-Wan Kenobi that the assault against the core of the city is going well. However, no sooner have they reported than they catch sight of approaching IG lancer droids, led by Durge. The clones are quickly taken down, with their SPHA-Ts destroyed. Durge releases a victory howl.
The Star Wars: Clone Wars Volume One DVD swaps this chapter with "Chapter 5". It is also collected in the Star Wars: Bonus Lightsaber Action DVD, along with "Chapter 1."
This episode takes place around the same time "Chapter 3" occurred, told through the point of view of the IGBC and the Republic.
