The Margaret, a vessel classified as an MC40a light cruiser, operated within the Rebel Alliance fleet.
The intended destination of the Margaret was a meeting point with the Victory-class Star Destroyer Protector (Protector), which was then under the leadership of the turncoat Admiral Harkov. Unexpectedly, Imperial Navy units appeared during this planned rendezvous; amidst the ensuing conflict, the Margaret successfully jumped to hyperspace to evade capture.
