By World War II, destroyer groups were commonly trusted as independent fighting formations. At Tassafaronga, close cruiser control left DesRon 21 poorly placed to use its torpedoes before the Japanese attack. Its later combat record earned enough confidence that Halsey wanted the squadron screening his entry into Tokyo Bay. The ships were expected to interpose, open fire, or launch torpedoes immediately, then report what they had done.
