The First Battle of Plagen took place on the planet of Plagen between the Confederacy of Independent Systems and the Galactic Republic as the two sides clashed during the Clone Wars, which occurred from 22 BBY and 19 BBY. Before the battle started, Confederate General Piar Nagelsa was killed by a T-series tactical droid on the Confederate side, due to issues most tactical droids had with serving under organic leaders. The droid then assumed command as it threw away Naglesa's tactical plan, before leading the Confederate forces to win the battle.
Behind the scenes
The First Battle of Plagen was first mentioned in 2012's The Essential Guide to Warfare, an extensive Guide on the conflicts in the Star Wars galaxy, written by Jason Fry and Paul R. Urquhart. Although it was given the title of the First Battle of Plagen, no other battles have been confirmed to have happened on that planet.
