For reasons of security, our submarine operations throughout the Pacific can be discussed only in very general terms. No branch of the naval service, however, has acquitted itself more creditably. Submarine commanding officers are skillful, daring and resourceful. Their crews are well trained and efficient. Their morale is high, and in direct ratio to the success of submarine operations. Materially our submarines are in excellent shape, and we have kept up to the minute in all features of design and scientific development and research. The versatility of our submarines has been so repeatedly demonstrated throughout the war that the Japanese know only too well that in no part of the Pacific Ocean are they safe from submarine attack. When the full story can be told, it will constitute one of the most stirring chapters in the annals of naval warfare.
