JustOK writes "Darth Vader did alot of bad things and did alot of things bad, and the Battle of Hoth was of both types. The Empire's attempt to capture Echo Base, while successful, was still a horrible failure. Sure, the Empire overran the ground defenses and captured the base, but most of the Rebels escaped. Luke, Leia and Han all got away. The Rebels had a poorly laid out ground defense, and a planetary "shield that can’t keep an invader out and complicates their own escape."
