Skirmish in unidentified asteroid field (Maarka)

"Right, Artoo! We've gotta find a way to sneak past those fighters and warn the base."

- Ahsoka Tano, to R2-D2

During the Clone Wars, a skirmish took place in an asteroid field near Maarka.

The skirmish
While on a mission to deliver a data file with important intelligence for the Republic base on Maarka, Ahsoka Tano was ambushed by six Vulture droid starfighters in an asteroid field. Loosing one of the two laser cannons on her Delta-7B Aethersprite-class light interceptor, she nonetheless managed to destroy her pursuers with a single shot on an asteroid, causing it to move and crash onto the droid starfighters.

Ahsoka Tano then proceeded with her mission, delivering the data file to the Maarka base and later meeting with the Resolute in the Outer Rim.
