Kosh was a Human male captain in the Imperial Stormtrooper Corps who was stationed on the planetTatooine in the years leading up to the Battle of Yavin. Kosh was the officer in charge of a local garrison ofstormtroopers. In 0 BBY, Rebel Senator Leia Organa's starship, the corvette Tantive IV, was interceptedabove Tatooine while in possession of the stolen plans for the newest Imperial superweapon, the Death Starbattlestation. Led by Dark Lord of the Sith Darth Vader, Imperial forces seized the ship but found no trace of the plans. Organa was also captured, but she had managed to hide the plans inside her astromech droid, R2-D2, who, along with his counterpart, C-3PO, used an escape pod to reach Tatooine's surface. After he was informed about the ejected escape pod, Vader believed that the plans were hidden aboard and ordered his forces to have the escape pod located and the plans secured.
Vader assigned Commander Nahdonnis Praji to supervise the search and recover the plans. While Vader's elite 501st Legion was being prepared, Praji appointed Kosh's garrisoned troops and the newly arrived Desert Sands sandtrooper unit under the command of Captain Mod Terrik to lead the search for the plans. After a brief landfall, however, Praji delegated the overall command of the operation to Kosh. The Imperial troops discerned that the two droids had been aboard the escape pod and followed their trail, discovering that a young moisture farmer, Luke Skywalker, had acquired R2-D2 and C-3PO and was heading to the Mos Eisley spaceport to secure passage off-world.
The troops under Kosh's command searched Mos Eisley but were unable to find any trace of the two droids, who were deliberately hiding from them. Kosh himself soon arrived at the spaceport in a Sentinel-class landing craft to oversee the search. As he was disembarking from the craft, flanked by two stormtroopers, the rest of the troops greeted him and snapped to attention. Although the search for the droids continued, a delay in coordination between Kosh's garrison, the Desert Sands, and the 501st allowed R2-D2 and C-3PO to escape Tatooine aboard the Millennium Falcon, a freighter captained by smuggler Han Solo. The droids and the plans were eventually delivered to the Rebel Alliance, allowing the Rebels to destroy the Death Star during the Battle of Yavin.
