The Escape from Invincius Fleet was the escape made by the Rebels in the Father Fleet and other people the Empire had captured that said they'd join the Rebellion if they made it out, which most of them did. They escaped in a Zeta-class cargo transport with the title CW-0043.
Before the escape[]
The Rebels had been captured during the Battle of Sector 9 lost previously. Their ships were boarded by stormtrooper marines and many were killed. But Admiral Nual opened the internal comm and gave the Rebels a chance to surrender. All but one Alliance ship agreed, and their ship and crew were destroyed fighting. The prisoners were transferred to multiple Star Destroyers. The one called Vickert was the ship in which the escape occurred. The other Rebels who were still in custody aboard other Star Destroyers were broken free later when Jamus Calmister and other Rebel spies infiltrated the Star Destroyers Cody's Arm and Grey.
The escape[]
It all began with Jamus in his cell with a non-Rebel Rodian named Parp Lisme who had been pre-captured for committing crimes against the Empire. Parp was drunk and skinny and was able to crawl through the ventilation systems and wind up outside the cell, freeing Jamus.
