The conflict known as the Battle of Crombach Nebula transpired within the Crombach Nebula at some point between 22 BBY and 19 BBY, amidst the larger Clone Wars. It involved the armed forces of the Galactic Republic clashing with those of the Separatist Alliance. During this engagement, the Jedi Master Wom-Nii Gnaden took part, piloting a Republic NTB-630 naval bomber in an attack against the Separatist Munificent-class star frigate called Tide of Progress XII. Tragically, Gnaden met his death when his bomber crashed into the Separatist frigate, leaving its mark on the starboard hull.
The initial mention of the Battle of Crombach Nebula within the current Star Wars canon occurred in the 2018 reference work, Star Wars: Complete Vehicles. Conversely, within the Star Wars Legends continuity, the Battle of Crombach Nebula was first presented in Star Wars: Revenge of the Sith Incredible Cross-Sections, a 2005 reference book created by Curtis Saxton.
