In the year 22 ABY, Luke Skywalker, the Jedi Master, initiated an attack against the Dreadnaught-class heavy cruiser Dreadnaught-Four, commanded by Estosh, the Supreme Commander of the Vagaari Empire. This action led to Skywalker discovering the coordinates of a meeting point where Estosh intended to bring Dreadnaught-Four. Following the killing of Estosh and his contingent, Skywalker divulged the rendezvous location to the Chiss Ascendancy, a nation that had been previously attacked by the Vagaari forces.
Subsequently, the Empire of the Hand's 501st Legion and the Ascendancy launched a surprise attack on a Vagaari attack force at the designated rendezvous as part of the Third Vagaari War. General Prard'ras'kleoni, known as "Drask" (core name), of the Chiss, and Imperial Commander Chak Fel were involved in this assault, which resulted in the destruction of the Vagaari Empire vessels'.
Timothy Zahn's novel Survivor's Quest, published in 2004, makes reference to this attack.
