Battle of Hoth (Earth-2042)

"My lord, the fleet has moved out of slipspace. Com-scan has detected an energy field protecting an area of the Hoth, in the Hoth system. The field is strong enough to deflect any orbital bombardment."

- General Maximillian Veers to Darth Vader

The Battle of Hoth, also known as the Assault on Echo Base, or the Evacuation of Echo Base was a major battle fought in 3 ABY and was considered a major victory for the Galactic Empire and the single worst battlefield defeat suffered by the Alliance to Restore the Republic during the Galactic Civil War. The battle was an Imperial invasion led by Darth Vader, aimed at destroying the Rebel Alliance's Echo Base hidden on the remote ice world Hoth and capturing Luke Skywalker.
