Siege of Mandalore

"Ahsoka Tano. I fought by her side from the Battle of Christophsis till the Siege of Mandalore."

- Rex

The Siege of Mandalore took place at the planet Mandalore during the Clone Wars. Clone Captain Rex took part in the conflict, as did ex–Jedi Padawan Ahsoka Tano, who had previously left the Jedi Order.

Behind the scenes
The Siege of Mandalore was first mentioned in "The Lost Commanders," the second season premiere episode of the television series Star Wars Rebels, which aired on October 14, 2015. Much prior to then, in March 2014, Supervising Director Dave Filoni released a number of conceptual art images from story arcs of the Star Wars: The Clone Wars television series that had not been finished prior to the series' cancellation. One of the images alluded to a story involving Tano and the Mandalorian Nite Owls leader Bo-Katan Kryze on account of being titled "Ahsoka Tano Appoints Bo-Katan As Provisional Leader."
