While the Carrow Conflict had initially gone in Rojka's favor, the arrival of a Jiralhanae fleet turned the tide against him. Retribution's Promise along with Rojka's other frigates had been sent in to replace the RPV-class light destroyers that had been obliterated. Most of the frigates were soon destroyed, however, with Retribution's Promise being one of the last one to go down.
