The Royal Navy is described as moving from a strong expectation of a mass fleet battle in the First World War toward task-group operations in the Second. The discussion credits interwar officers with developing that approach. Cunningham and Somerville are named as commanders who put it into practice. The comparison then turns to Japanese expectations that the Americans would arrive as a concentrated fleet, and the difficulty of responding when they operated as task forces.
