“Chapters II and III deal with the Submarine Campaign in 1917 and the measures adopted to win success. The gradual naval control of all merchant shipping with its attendant difficulties is clearly shown. The tremendous labour involved in putting into operation new measures; the unremitting search for and development of new antisubmarine devices is revealed, and above all the length of time necessary to put into operation any new device, and this when time is the most precious element, is pointed out.
“That a campaign against the enemy must be waged with every means at hand; that new weapons must be continually sought; that no ‘cure-all’ by which the enemy may be defeated without fighting can be expected; that during war is the poorest time to provide the material which should be provided during peace, the Admiral shows in a manner not to be gainsaid.
“Chapters IV and V deal with the testing, introduction, and gradual growth of the convoy system. It is shown how the introduction of this system was delayed by lack of vessels to perform escort duty and why when finally adopted it was so successful because it was not only defensive but offensive in that it meant a fight for a submarine to attack a vessel under convoy.
“Chapter VI is devoted to the entry of the United States. The accurate estimate of our naval strength by both the enemy and the allies, and our inability upon the declaration of war to lend any great assistance are shown—and this at the most critical period for the Allies—a period when the German submarine campaign was at its height, when the tonnage lost monthly by the Allies was far in excess of what can be replaced—when the destruction of merchant shipping if continued at the then present rate would in a few months mean the defeat of the Allies.”

I will give you what Admiral Caspar F. Goodrich said in the Weekly Review (30 April 1921; The Weekly Review has since been combined with The Independent) regarding A History of Sea Power, by William O. Stevens and Allan Westcott:
“Two professors at the Naval Academy, the one a historian, the other a close student of Mahan, have written a noteworthy volume in their History of Sea Power, published in excellent form, generously supplied with maps, illustrations, and index. The title suggests Mahan’s classic which is largely followed in plan and treatment. It will be remembered that his writings covered in detail only the years from 1660 to 1815. While not neglecting this period, this book is particularly valuable for events not within its self-assigned limits. Practically it is a history of naval warfare from ancient times to the present day. Each chapter deals briefly, but ably, with one epoch and closes with an appropriate bibliography for those who care to go more fully into the question; a commendable feature. The last chapter, ‘Conclusions,’ deserves especial attention. Naturally, considerable space is devoted to the story and analysis of Jellicoe’s fight. Few will disagree with the verdict of the authors:
“‘It is no reflection on the personal courage of the Commander-in-Chief that he should be moved by the consideration of saving his ships. The existence of the Grand Fleet was, of course, essential to the Allied cause, and there was a heavy weight of responsibility hanging on its use. But again it is a matter of naval doctrine. Did the British fleet exist merely to maintain a numerical preponderance over its enemy or to crush that enemy—whatever the cost? If the Battle of Jutland receives the stamp of approval as the best that could have been done, then the British or the American officer of the future will know that he is expected primarily to ”play safe.“ But he will never tread the path of Blake, Hawke, or Nelson, the men who made the traditions of the Service and forged the anchors of the British Empire.’
“One factor in the success of the antisubmarine campaign is not mentioned, important as it proved to be. This was the policy adopted by the Allies of not giving out the news that any U-boat was captured or otherwise accounted for. Confronted with this appalling veil of mystery the morale of the German submarine crews became seriously affected; volunteering for this service gradually ceased; arbitrary detail grew necessary; greatly lessened efficiency resulted.
“The authors are to be congratulated on producing a volume which should be in the hands of all naval officers of the coming generation; on the shelves of all who take interest in the development of history; and of statesmen upon whom may eventually rest the responsibility of heeding or not heeding the teachings of Mahan as here sympathetically and cleverly brought up to date.”
