They key point is "fire control" You don't want to randomly throw water on a fire, which likely won't impact the fire in itself, but destroy the things not touched by the fire. For getting a fire down you either have to prevent it from access to oxygen or prevent spreading. A big fire like that can't be covered completely to be cut of from oxygen. With fire control you can however try to cool down the areas close to inflammation to prevent further spreading. Save what can be saved, like the lower walls.
