Hi,
Yggdrasil suffered a misjump on her return trip home, one that rendered her KF drive and transit engines inoperative. Using her projected course data and a lot of small, independent scouts to scour the systems in and along that route, the Lyrans managed to find the dead ship--with no small amount of sheer luck--several light-years off from one of her jump points (far enough that her distress signal was not received yet). The found a ship whose fuel supply and food stores had run out years before, starving off what remained of her stranded crew.
The recovered vessel was eventually returned to the Gibbs JumpShip yards for repairs, re-crewing, and resupply, all performed under exceptionally tight security (like "shut-down-the-local-HPG-and-shoot-anything-not-squalking-a-trusted-IFF-and-don't-let-those-scouts-out-of-debriefing-for-several-months" tight) to get her back into the fight. Even then, she was a cursed ship, and became something of the Yorktown-at-Midway of the Jihad, getting pounded to a burning hulk and presumed a write-off for at least two more actions in the war.
Hope that helps,
