ABSTRACT
Having followed separately the developments of Pollen’s A.C. system and the Dreyer Tables, we can now address two crucial questions. First, what were the influences that shaped the rival systems? In particular, what debts in principles and technique did each owe to the other and, indeed, to the older manually worked system that had preceded them into service? Second, what were the critical choices in fire control made by the Admiralty: and what considerations determined, and perhaps justified, those choices?
