Six standard months following the Battle of Yavin, a less-than-reputable bounty hunter provided the Galactic Empire with some information. This information prompted the Empire to initiate an attack against the spaceport of Mos Eisley on the planet of Tatooine, with the intention of finding and capturing their target, the Rebel operative Luke Skywalker. This all happened half a year after the battle.
The Official Nintendo Player's Guide for the Star Wars: Rogue Squadron video game, published in 1998, included a reference to this bounty hunter.
