Battle of Agamar (Clone Wars)

Around 19 BBY, a battle occurred on the planet Agamar during the Clone Wars between the Galactic Republic and Separatist Alliance. Prior to the battle, the ST-series military strategic analysis and tactics droid General Kalani was ordered by Separatist leader, Count Dooku, to await deployment at Agamar alongside the remaining forces from the government's defeat at the planet Onderon in 20 BBY. Above Agamar, however, Kalani's DH-Omni Support Vessel was attacked by Republic forces and crashed on the planet's surface.

Not long after the engagements, following the activation of Order 66, which forced the Republic's Grand Army to execute the Jedi Order, a command was issued by the Sith apprentice Darth Vader that ordered the deactivation of the Separatist Droid Army. However, assuming that it was a Republic trick, Kalani refused the order and left his battle droids online, and they remained on Agamar's surface for seventeen years before being discovered during the reign of the Galactic Empire.
