In 20 BBY , Appo served as a sergeant in the 501st Legion by the time of the Republic invasion of Umbara . At first he fought the Separatist - aligned Umbaran s under the leadership of Anakin Skywalker , a Jedi Knight and general of the Grand Army . However , Skywalker was recalled to the Republic capital of Coruscant , leaving Appo and the legion under the command of another Jedi officer , General Pong Krell , for the duration of the campaign .

The attack on the Jedi headquarters drew the Alderaanian senator Bail Organa to the Temple , only to be barred from entering the facility by Appo and a contingent of the 501st . The commander claimed that the Temple had become the site of a " Jedi rebellion " and threatened Organa at the point of a blaster when the politician initially ignored the clone ' s attempt to block his path .
