Why Vella Gulf was a decisive destroyer action

What makes the Battle of Vella Gulf a notable destroyer action?

Six American destroyers defeated four Japanese destroyers and sank three, using capable ships to turn a limited numerical advantage into a decisive result.

The exchange treats Vella Gulf as an impressive destroyer victory without presenting it as a Samar-sized mismatch. Six American destroyers faced four Japanese ships and sank three of them. The Japanese vessels are described as relatively small escort-like destroyers, while the American force included capable Mahan, Gridley, and Benham-class designs. The result therefore illustrates how a well-handled destroyer formation could turn a modest numerical edge into a crushing tactical outcome.
