The New Georgia offensive, Circa 1943, had two task force each formed around four light cruisers and a squadron of new 2,100 DD's under the command of W.L. (Pug) Ainsworth and the other under A.S. (Tip) Merrill.
Over a two week period nightly operations resulted in battles at Kula Gulf & Kolombangara in which the IJN "Long Lance torpedo" cost Ainsworth another four cruisers, one sunk, three damaged. Ainsworth was embarrassed and wrote to ADM. Nimitz, "No one knows the fallacy of chasing *** torpedo boats with cruisers better than I".
The dissection of a beached "Long Lance" revealed how lethal these weapons were, thus outweighing the risk of putting CL's in jeopardy.
"To the delight of destroyer men, this meant that the Solomon campaign was about to become a pure DD fight." Dave Newcomb, US Destroyers 1934-45
Thus the Little Beavers and 31-Knot Burke begin to take the war to the IJN.
