Within the archives of the New Republic, specifically in the "Imperial Prisoners" area, a file existed named Interrogations 143. This file documented the ambush that Imperial forces perpetrated against an Alliance to Restore the Republic convoy within the Derra system during 3 ABY. The document noted the participation of the Star Destroyers _Vigilance_ and Dark Omen, along with the Interdictor cruiser Retention. Beaumont Kin, a historian, referenced this specific file in 35 ABY within his book, The Rise and Fall of the Galactic Empire.
Dr. Chris Kempshall authored the reference book Star Wars: The Rise and Fall of the Galactic Empire (2024), where Interrogations 143 is referenced.
