The 331st Destroyer Squadron consisted of Federation destroyers that were assembled by Starfleet Command in 2282 and 2283, during a period when the Organians seemed to have lost interest in Federation-Klingon affairs.
This task force was assembled during the Klingon Empire's Taal Tan Offensive. On 06 September 2283, the 331st stumbled on the Klingon resupply efforts. While the warships were able to complete their resupply activities, one L-9 frigate is damaged beyond repair. The Klingons scuttle it while driving the Federation squadron off. The resupply freighters are inadvertently driven towards Federation reinforcements and are either captured or destroyed. (The Taal Tan Offensive)
