During the year 0 BBY, the Stimsenj'kat led a retrieval mission in an asteroid field to obtain a large supply of lonsigar that had been abandoned in a pair of cargo containers. The vessel deployed six Delta-class DX-9 stormtrooper transports from Renhoek group to unload the containers and bring back the lonsigar.
Unfortunately, the operation turned out to be an Imperial trap when three Nebulon-B frigates came out of hyperspace and launched waves of TIE Fighters, TIE Bombers, and TIE Avengers to exterminate the Rebels.
Fortunately, Rebel pilot Keyan Farlander and the other pilots destroyed most of the Imperial forces and bought the Stimsenj'kat the time it needed to finish the cargo transfer and to flee into hyperspace.
