Exercises and technical preparation could not fully reproduce the mentality required for a world war. The northern force lacked even an informal routine ensuring that at least one senior commander among the three cruisers remained awake while operating near an active enemy. British forces in 1939-40 and American forces in 1941-42 both struggled to replace peacetime assumptions with the vigilance required against a peer threat. In this interpretation, Savo Island and Tassafaronga were severe defeats whose lasting measure includes whether the Navy learned from them, rather than whether every lost cruiser can be traced to a defective design.
