Mission to Onderon (Galactic Civil War)

The Mission to Onderon was a reconnaissance operation on Onderon undertaken by the Alliance to Restore the Republic.

The mission
During this mission, Rebel scout Sasha and her detachment accidentally gave away their position to Imperial forces after blaster fire was directed against Onderon's dangerous native wildlife. The Imperials in turn responded with heavy artillery and sent a division of AT-STs to their last known position. This mistake was critical, as it motivated the Rebel high command's decision to leave Sasha and her unit to their own peril, being denied any further support. Of those in the unit under heavy fire, only Sasha survived.

Aftermath
Sasha, the only survivor of her unit, went into hiding in the planet's hinterlands, remaining stranded on Onderon for some time. Her forsaking by the Rebels broke her loyalty to the Rebellion.
