A speculative bridge from Arethusa to Town-class cruisers

La Argentina's Arethusa-like displacement and forward battery raise the possibility that she preserved ideas from the cancelled fifth and sixth members of the British class. Those projected ships might have used three triple 6-inch turrets before their orders re-emerged as larger Town-class cruisers with four triple mountings. This is an interpretation rather than a documented design lineage. The foreign order may offer a clue to British thinking during the transition from a small cruiser design to a more heavily armed successor.
