Operation Durge's Lance
this was the codename of the Separatist attack that planned to take control of the Corellian Trade Spine during the height of the Clone Wars. After capturing Yag'Dhul and Thyferra, the Confederacy of Independent Systems tried to wrest control of the Duro System from the Old Republic. If Duro could be captured, only Corellia would remain part of the Old Republic. Corellia's capture would give the Separatists control of the entire trade route. The operation launched a massive attack on the Republic warships stationed at Duro, eliminating the Acclamator-class assault ships Anvil, Coronet, and Bolide, as well as the Dreadnaughts Prominence and Atrisian Iron.
