In 2554, after URF forces captured the capitol building in New Albany, ONI sent in Alpha-Nine to take out the leadership of the rebels. At first, the ODSTs gained considerable ground on the rebels. Despite strong defenses around the capitol building, Alpha-Nine managed to fight their way into the heart of the building, making it to the legislature floor that the rebels used as their headquarters.
Ingridson's forces managed to successfully trap and pin Alpha-Nine, forcing the confrontation into a stalemate. One of the ODSTs, the Rookie, attempted to flank around behind the rebels who had Alpha-Nine trapped. Captain Ingridson captured the Rookie, however, and attempted to use him as a bargaining chip to force the rest of the ODSTs to surrender. Her attempt failed and she ended up killing the Rookie before being killed by Dutch.
