Battle of Dantooine (Galactic Civil War)

Prelude
Imperial Transmission from Grand Moff Tarkin, encoded to the imperial stormtrooper commander:

"The Galactic Empire has a small outpost on Dantooine, left over from the Clone Wars. It seems as if the Rebels would like this outpost as their own. Do not let this happen. It will be difficult because Dantooine is a planet covered in tall grass. This grass will be the most dangerous thing on this battlefield. Darth Vader has arrived to make the point personally that Rebels are unwanted. He does not have the protection of the 501st Elite Legion this time though. The reason for that is because he would like to prove that he is a force to be reckoned with on his own. He certainly is a powerful character."

The Battle
The rebels assaulted the outpost so as to eliminate the imperial presence on Dantooine so that their base on the planet could remain undetected. The battle progressed, with the rebels gaining air superiority and finally eliminating the wall of AT-TEs with their LAAT/i gunships. The rebel infantry then moved in and captured the small imperial outpost, destroying imperial turrets along the way.

Aftermath
The rebel base on Dantooine remained undiscovered until much after it was abandoned in favor of Yavin base.
