A clash occurred within the Hewett system amidst the Orinda campaign of 12 ABY in the Galactic Civil War. Following the seizure of six star systems bordering the Entralla Route by Gilad Pellaeon, the new Head of State of the Imperial Remnant, as a demonstration of power aimed at the New Republic, the Executor-class Star Dreadnought named Lusankya was sent to oppose the Imperial forces. During Lusankya's journey, the Imperial 181st Imperial Fighter Group, commanded by Turr Phennir, seized control of both Hewett and Tartaglia from the New Republic, aided by a group of Imperial-class Star Destroyers.
