Raid on Kammia colony

The Battle of Kammia was fought during the Ssi-ruuvi invasions in 2 ABY. The Kammia colony was one of many small human colonies that were lost to the invaders.

Prelude
When Emperor Palpatine made contact with the alien invaders called the Ssi-ruuk, he made a deal with them: In exchange for their battle droid technology, the invaders were allowed to attack smaller colonies at the edge of colonized space. The Kammia colony in the Drynn system was one of these.

The battle
Not much is known about this battle, except that the Ssi-ruuk won and the miners were either killed during the fight or enteched afterwards.

Aftermath
Since the Empire wanted to keep the presence of the Ssi-ruuk a secret, the Imperial Colonization Board released a cover-up story at 37:4:21, which was published through Imperial Holovision and Galaxywide NewsNets. According to it, the entire colony succumbed to a "mysterious" virus, that evolved from Chandrilan grain brought to Kammia by the colonists.

Nonetheless, rumors escaped about this and other incidents and spacers whispered about them in the galaxy's cantinas.
