Would 9.2-inch cruisers shadowing Bismarck have attacked rather than maintained contact?
Short answerThey would probably keep shadowing at first, but might join once Holland arrived because their guns could inflict serious damage.
NotesShadowing preserves contact and avoids risking the only ships able to report Bismarck's position, so better guns do not erase the mission. The cruisers would probably continue tracking rather than attacking alone. Their 9.2-inch batteries become more relevant once Admiral Holland's force arrives, when a coordinated crossfire might be worth the risk. The existence of such ships also changes German design choices by forcing a response in the Hipper-class armament debate.
