Graf Spee's six 11-inch guns did not remove the risk of operating alone without repair support. Damage could make a lone raider's eventual destruction likely even if the ship survived the immediate fight. Graf Spee needed to sink her opponents to eliminate them, while damage alone could leave her unable to survive the pursuit. After the Battle of the River Plate, Cumberland joined Ajax and Achilles while more cruisers, Renown, and Ark Royal approached. Those reinforcements made the stay in Montevideo dangerous for Graf Spee.
