How Britain and France would hunt a Captain Romani-class raider

If a Captain Romani-class ship caused trouble, would Britain and France send a light cruiser after it?

Probably, although a group of destroyers could also overwhelm it and Britain would not insist on a one-for-one fight.

The hypothetical raider is a capable small combatant, although its limited armour leaves it vulnerable to concentrated pursuit. A light cruiser could be dispatched, while several destroyers would also provide enough combined capability to deal with it. The Royal Navy would use its numerical advantage instead of arranging an equal contest. Commerce-raider comparisons therefore need to account for the hunting force a major navy can assemble alongside individual ship specifications.
