Found perhaps a slightly useful snippet. Mechwarrior's Guide to the Clans (page 50) includes a sample character template for a "disgraced warrior." He's a Smoke Jaguar who fought in the Inner Sphere. It doesn't read like he was on Huntress, more like he was horrified to learn that the Spheroids had gotten there. It isn't clear where he was when it all went down. He reads like he had no way to get home (Huntress) and no one was willing to assist him. When Clan Smoke Jaguar died, he ends up in the dark caste. The way his background is written, he basically blames the Clans in general for turning their backs on Clan Smoke Jaguar. So he felt justified turning his back on the Clans.
We know several Jaguar warriors ended up as bandits/pirates/dark caste. Even 1-2 warships.
The Clan Smoke Jaguar page on Sarna has a subsection called Annihilation Survivors that covers the various accounts we have of former Jaguars popping up, often as bandits, pirate bands, even Solaris gladiators.
I think what happened here is the Clan died. The Jaguars were annihilated as of the Great Refusal. What was left at that point.. think of them like ronin, masterless warriors. Their stories vary a lot from person to person. The Clan was gone, and they scattered to the wind. Alone or in small groups.
What they didn't do (by all canon accounts), was try to defend the Clan's enclaves in the name of Clan Smoke Jaguar. Because the Clan was dead. Which is a great excuse for the other Clans to treat any remaining warriors like bandits anyway. To NOT to have to treat them like honorable warriors, and just steamroll them if they do stand and fight.
That's pretty consistent with canon events. Which always make it sound like in the aftermath of the Great Refusal the other Clans scooped up the Jaguar enclaves and didn't have to fight any Jaguars to do it. Most often they fought other Clans who had shown up to acquire those same enclaves. But there's no mention of any holdout Jaguar warriors having an Alamo moment.
That could change someday. There may be some unwritten stories in there of some holdout Smoke Jaguars. After all the story surrounding the Fidelis was only told in recent years, a very long time after the Twilight of the Clans novels were published.
