How a sloop supported a cruiser against heavier ships

Folkestone could not defeat Japanese heavy cruisers, but a second British hull protected the merchant ship's other flank and made the mission a visible squadron commitment.

Question

What practical use was a sloop beside a light cruiser facing several heavy cruisers?

Short answer

It covered the merchant ship's other flank and turned the mission into a two-ship force, adding tactical coverage and diplomatic weight despite its light gun armament.

Notes

Folkestone's value at Tsingtao was tactical and political rather than a matter of matching gun power. She could lead the detained merchant ship out while Birmingham covered from astern, protecting both sides of the merchantman. An opponent would have to fight a commissioned warship to brush the sloop aside, raising the diplomatic cost of interference. Two British ships also made the recovery mission a squadron commitment. A contemporary comparison points to the Strait of Hormuz, where one frigate was followed by additional deployments because a second hull was needed. Modestly up-armed, forward-deployed River-class patrol vessels are offered as a cheaper way to provide that second hull.
