Operation Detachment or Battle of Bastion in 19 ABY was a decisive victory by combined assault of Confederate forces led by General Nicole Kroger and Rebel Alliance forces led by the Luke Skywalker over an Imperial Army commanded by Darth Skillet and Admiral Needa. It proved to be the last major land battle of the War of Secession, as the surrender of Skillet's army prompted the Imperial government eventually to negotiate an end to the conflict.
