Eventually, Mison turned to smuggling, plying his trade on the Shipwrights' Tracehyperlane. During the Galactic Civil War, he accepted a job to ferry supplies to Farbinda III, where a group of conscientious objectors had established a colony. Upon arrival, he discovered that an Imperial strike team had landed on Farbinda III, where they had rounded up the local populace who offered no resistance. Mison watched as the Imperial summarily executed the colonists. Horrified, Mison spent several months deliberating on the events before deciding to join the Alliance to Restore the Republic[1] shortly following the destruction of the first Death Star at the Battle of Yavin in 0 BBY. For a time, Mison served the Rebellion at Massassi Station on the moon of Yavin 4.[2]
However, Mison's escort failed to see the Bright Hope through the Imperial blockade waiting in Hoth's orbit. A combined attack by Imperial Star Destroyers and the Mist Hunter, the craft of the bounty huntersZuckuss and 4-LOM, all but destroyed the Bright Hope before it could reach the safety of hyperspace. Seeing that there was nothing they could do for the Bright Hope and that no rescue attempt could be made for any possible survivors, Mison and the five escorting X-wing pilots escaped into hyperspace themselves.[6]
A skilled pilot[1] and expert marksman,[2] Tarn Mison's interests generally revolved around credits rather than politics. However, upon witnessing the Imperial atrocity on Farbinda III, Mison's conscience led him to join the Alliance to Restore the Republic to oppose the Empire.[1] He had brown hair and a beard.[2]

"Yes, they got the artist's [sic] together to do a scene that was played out over a Matte painting that I had done of Rebel ships parked in the Ice cave. We were going to be Rebel soldiers…Joe Johnston, Harrison Ellinshaw [sic] and Mike Pangrazio, stood in the foreground and had a few lines…"
Tarn Mison first appeared fleetingly as an unidentified Rebel pilot extra in the film Star Wars Episode V: The Empire Strikes Back, barely visible as he passes in front of the camera for a brief moment during the scene in which Echo Base personnel discuss the Rebels' evacuation procedure pursuant to the Battle of Hoth.[4] Although uncredited, Industrial Light & Magic matte artist Michael Pangrazio portrayed Mison in the film. In fact, all of the Rebel characters present in the Mison scene were ILM artists, including Ralph McQuarrie, Joe Johnston, and Harrison Ellenshaw.[7]
Mison's backstory was later expanded on in 2012's The Essential Guide to Warfare by Jason Fry and Paul Urquhart. No mention was made of Mison's time as an Imperial pilot, instead concentrating on his bush pilot abilities and his reason for joining the Alliance. This article assumes that both accounts are correct, and that his time as a smuggler came after his stint as an Imperial pilot.
