Chase through the Hoth Asteroid Field

"Asteroids do not concern me, Admiral. I want that ship, not excuses."

- Darth Vader, during the search for the Millennium Falcon

Immediately after the Battle of Hoth, Han Solo, Leia Organa, and Chewbacca, along with C-3PO, left the planet on board the Millennium Falcon, and were intercepted in space by Imperials.

The Chase
Upon leaving the planet's gravity well, they soon realized that the hyperdrive malfunctioned, leaving them without an easy escape route. Han, with Imperials on his tail, maneuvered into the nearby asteroid field, hoping to gain some time and lose some of the Imperials.

Eventually, after dodging multiple asteroids, Han piloted the Falcon inside of what appeared to be a cave inside one of the bigger asteroids. The next day, after minor repairs, the group realized that their resting place was not a cave at all, but was actually a Space Slug. The ship barely made it out of the beast on time, before it shut them in with its huge jaws.

Back on the Star Destroyer, Vader enlisted the bounty hunters, Boba Fett, Dengar, IG-88, Bossk, 4-LOM and Zuckuss to find the Millennium Falcon for a "substantial reward". One of the Imperial commanders finally spotted the Falcon, leading to another pursuit which resulted in the Falcon eluding the Empire by making the insanely counter intuitive move of attacking the lead Star Destroyer. However, at the last moment, the ship veered off and secretly attached itself to the ship, which was not extensively covered by sensors, making it appear to have vanished in the Empire's point of view.

When the fleet scattered to search for the Falcon, the Rebels waited for the ship to do its standard dump of refuse before jumping, then detached to float away with it. The Falcon's hyperdrive needed repairs, so Han decided to make their way to Cloud City, a gas-mining colony on Bespin, run by his "old friend" Lando Calrissian. Unfortunately, the bounty hunter Boba Fett had deduced the Falcon's escape method and had his ship jettisoned with the waste to stealthily follow the fugitives.

Fett made a short hyperspace jump to nearby Bespin, getting there before the Rebels, and alerting the Empire to their destination.
