Battle of Gorash VII
The Narn Regime gathered the bulk of its remaining fleet for an attack on a Centauri supply station at Gorash VII. Their expectation was that the attack on their supply lines would force the Centauri to fall back and regroup while establishing an alternate supply line.
Centauri intelligence had discovered the Narn plan, but Lord Refa developed a plan to directly attack the Narn homeworld while the main fleet was distracted. He persuaded Londo Mollari to involve his Shadow allies in the war to counter the Narn attack on Gorash VII while the main Centauri fleet attacked Narn.
The battle transpired almost exactly as Lord Refa desired. The Shadows destroyed the entire Narn force without losing a single ship. The Centauri attack on Narn was virtually unopposed, and the Centauri fleet commenced bombardment of Narn with mass drivers, forcing the Narns to surrender within a few days.
