Two-pounder fire against escort flotillas

If a quad or octuple 2-pounder mount could depress low enough, how lethal would it be against escort flotillas?

They would be extremely dangerous at close range, especially when the mounts could depress low enough to engage surface targets.

Many 2-pounder pom-pom mounts could depress far enough because they were expected to engage low-flying torpedo bombers. Against small escort craft at close range, a quadruple or octuple mount would deliver punishing rapid fire. The discussion then points to the later 6-pounder and Molins-gun concept as a heavier solution for small surface targets. The mount has to depress far enough to bring its fire to bear on a surface target.
