Suoi Tre functioned as a cargo ferry utilized by Dimok military groups throughout the duration of the Sepan Civil War.
As the Sepan campaign neared its conclusion, the Imperial Escort Carrier known as Tropsobor transported a shipment of TIE Avengers to Admiral Harkov's command ship, the Victory-I class Star Destroyer called Protector, positioned in proximity to Gerbaud 2.
In an effort to hinder the delivery of the Starfighters, the Dimoks, collaborating with Ripoblus forces, launched an offensive targeting both the Protector and Troposbor, deploying several vessels. The Suoi Tre, in conjunction with Can Giouc, participated in the assault against the Protector.
The TIE Avengers were preserved due to the valorous actions of Maarek Stele, and it is presumed the Cargo Ferries were obliterated during the engagement.
