Did the Arethusas carry dual-purpose four-inch guns?

Did Arethusa-class cruisers have dual-purpose four-inch guns?

Yes, they carried some dual-purpose four-inch guns, but those weapons did not change the class's reliance on torpedoes against larger ships.

The Arethusa class carried some dual-purpose four-inch guns. They were useful additional weapons rather than the defining feature of the ship's tactics. Against larger surface combatants, the emphasis remained on speed, six-inch covering fire, and a close torpedo attack. The dual-purpose label therefore did not provide an all-purpose answer to the class's surface-combat problem.
