Would spare battleships be used for shore bombardment?

Would the enlarged Anglo-French fleet use several capital ships for shore bombardment?

Possibly, but not simply because the ships were available; once the priority objective was destroyed, the risk could outweigh the value.

A viewer asks whether the expanded Allied margin would encourage a bombardment by several capital ships. Planners might attempt such an operation, but mission value still governs the decision. If the important objective has already been destroyed, exposing the ships brings little additional gain. More hulls widen the option set, but do not remove the need to preserve them for other operations.
