My question always circles back to this: if serpent had wiped out or driven away by the 2nd jag wave and another clan helping what would bulldog have done?
Broadcast " give us the jags in a fair fight or get whacked"?
And the answer will always be the same...
IF the Jags had managed to defeat Serpent, there would have been no point to Bulldog landing on Huntress. The Jags likely needed only a short breathing space to get their SDS system up and running and we know they had forces elsewhere in the Cluster. Corbett took a strong force with him to Tranquil for some reason.
Victors forces were a rescue mission - if there was no one to rescue, their best option would be to let the rest of the Clans predate on the Jags.
Would the Jags have survived? It's possible, but only if the other Clans don't gang up on them. If the other Clans kept initiating Trial after Trial after Trial, then they'd fold. But they'd have ten regiments of Inner Sphere salvage, nearly four Galaxies of salvage of their own and Serpent did not manage to destroy every factory even in the official timeline. They'd also have thousands of lower caste truebirths they could tap as troops and the support of the ilKhan. Not to mention the forces they still had available elsewhere in the Cluster who could be redeployed, and the various Brian and naval caches we know they still had.
And the other Clans could easily have been distracted by the Trials for the Nova Cats and Ghost Bears.
The Jags would definitely lose territory. Whether they would be destroyed in such a scenario is debateable and depends on several factors we can only guess at.
