"Calculating risks does not mean taking a gamble. It is more than figuring the odds. It is not reducible to a formula. It is the analysis of all factors which collectively indicate whether or not the consequences to ourselves will be more than compensated for by the damage to the enemy or interference with his plans. Correct calculation of risks, by orderly reasoning, is the responsibility of every naval officer who participates in combat, and many who do not."

“Discipline is willing obedience to attain the greatest good by the greatest number. It means laying aside, for the time being, of ordinary everyday go-as-you-please and do-what-you-like. It means one for all and all for one- teamwork. It means a machine- not of inert metal, but one of living men- an integrated human machine in which each does his part and contributes his full share.”

“I expect the officers of the Atlantic Fleet to be the leaders of what may be called the pioneering spirit- to lead in the determination that the difficulties and discomforts- personnel, materiel, operations, waiting- shall be dealt with as "enemies" to be overcome by our own efforts.”

“During the war I kept neither a diary nor notes. I had then neither the time nor the inclination, and like most sailors, who through necessity "travel light," I have not accumulated any substantial body of personal papers. Since my relief as Chief of Naval Operations on 15 December 1945, I have spent many hours in recalling the events of World War II and of my earlier life in the Navy. My source has been my memory, verified and supplemented by references to official records and by the recollections of officers who assisted me in my wartime duties. The reader must therefore take this book on faith, for its statements are not bolstered by citations of numerous documents. I must ask him to believe, however, that I have made a sincere and conscientious effort to avoid the inspiration of hindsight and to record matters as they seemed at the time.”

“The day after Pearl Harbor our Navy's position in the Pacific was extremely grave. The bulk of our major ships had been put out of commission for a year; only our small Asiatic Fleet under Admiral Hart in the Philippines and portions of the Pacific Fleet that had been absent from Pearl Harbor on the day of the attack were in fighting condition in the Pacific. Even Hawaii might be attacked and overrun at any moment. And in the Atlantic the Axis submarines were destroying a tremendous tonnage of our shipping within sight of our very shores. Then, even at the lowest of the war tide, the decision was made, and correctly: first fight for time, especially in the Pacific- and then assemble the might to conquer first Italy and then Germany, and then inevitably Japan must succumb.”

“In the last analysis, Russia will do nine-tenths of the job of defeating Germany.”

“The mark of a great shiphandler is never getting into situations that require great shiphandling.”
