Wolstenholme, a human woman and First Order officer, achieved the military rank of captain. She was dispatched to the world of Hays Minor to supervise extraction activities. During the sabotage of the mining endeavor by Paige and Rose Tico, the sisters caused a diversion. A First Order stormtrooper then notified Captain Wolstenholme, which inadvertently left the navigation and weapon systems of the First Order's mining bombers vulnerable.
