A heavily fortified Cardassian planet, headquarters of the Twelfth Order, which Gowron orders Martok to attack with a hopelessly small force in Tacking into the Wind.
Sarpedion V is among the best defended worlds in Cardassian space. In Tacking into the Wind, set in 2375, the Klingons are the only allied force able to fight, since their ships alone can withstand the Breen energy-dampening weapon.
Chancellor Gowron, who has taken personal command, has been throwing those ships into reckless offensives in order to discredit the popular General Martok. His latest plan sends Martok against Sarpedion V with a force that every officer present knows to be far too small.
Worf denounces the order in front of the assembled officers as a political manoeuvre that is wasting Klingon lives. Gowron draws his bat'leth, and Worf kills him in single combat. Worf refuses the chancellorship and names Martok instead, and the assault on Sarpedion V never takes place.
