During the initial stages of the Clone Wars in 22 BBY, the Confederacy of Independent Systems initiated a siege on the planet of Hisseen. In response to this assault, the Jedi High Council deployed Jedi Generals Obi-Wan Kenobi, Plo Koon, and Anakin Skywalker, accompanied by a force composed of clone troopers, with the mission of stopping Hisseen from being captured by the Separatists. As the battle unfolded, Kenobi, Koon, and Skywalker engaged in lightsaber combat with Count Dooku and his Sith apprentice, Asajj Ventress, after the Separatists seized control of the Hisseenian parliament, holding them as hostages.
