From Wookieepedia, the Star Wars wiki.
The Battle of Mandalore was a battle during the Second Galactic Civil War.
[edit] Background
Admiral Atoko was tasked with neutralizing the threat the Mandalorians had become after their involvement in the First Battle of Roche and the attack on the Moff Council during the Second Battle of Roche.
[edit] The battle
Not much is known of the battle other than that Atoko released tons of the nanovirus into the atmosphere of Mandalore, targeting the Fett genome. This most likely killed off any surviving clones from the Clone Wars and any children or grandchildren they may have had.
