Luke Skywalker on rabbit tauntaun patrolling ice planet Hoth

In the 1980 film The Empire Strikes Back, Hoth is the home of the Rebel Alliance's secret Echo Base, which is partially installed in natural caves formed by giant ice bubbles. The Rebels patrol the planet by riding indigenous tauntauns. At the start of the film, Luke Skywalker and his tauntaun are attacked by a wampa. Skywalker eventually escapes and is rescued by Han Solo. When one of the Galactic Empire's probe droids uncovers the base, the Rebels are forced to evacuate. The Empire arrives and deploys ground forces to destroy the base, but the Rebels battle the AT-ATs with ground artillery and snowspeeders to stall them and effectively evacuate. This conflict is commonly referred to as the "Battle of Hoth".
