History of United States Naval Operations in World War II

The "History of United States Naval Operations in World War II" is a 15-volume account of the United States Navy in World War II, written by eminent historian Samuel Eliot Morison and published by Little, Brown and Company between 1947 and 1962.

Immediately after the attack on Pearl Harbor, Morison, already convinced of the value of personal involvement as a result of sailing experience while writing his biography of Christopher Columbus, wrote to President Roosevelt suggesting the preparation of an official history of the Navy in the war, and volunteering for the task. Both Roosevelt and Secretary of the Navy Knox agreed, and in May 1942 Morison found himself a Lieutenant Commander in the United States Naval Reserve, with permission to go anywhere and to see all official records. Morison's reputation as a knowledgeable sailor (based on the analysis in his Columbus biography) preceded him, and he was welcomed on a number of ships, 11 in all by the end of the war.

The result was a normal historical work, not an official history. Limitations of the "History" are mostly due to its time period; some material, especially related to codebreaking, was still classified, and later in-depth research into particular episodes would clarify points that had been passed over lightly. Some fixes were incorporated in later printings. The "History" also avoids a certain amount of analysis, for instance deferring to other works for the causes of the Pearl Harbor attack. The intended audience for the work, to quote from the preface, "the general reader rather than the professional sailor".

The "History" also played an indirect role in the history of television. One of Morison's research assistants in the project, Henry Salomon, was inspired to create an ambitious documentary series on WWII naval warfare. Several years after the war, NBC bought Salomon's idea, which eventually became "Victory at Sea". The success of that series played a major role in establishing the historic documentary as a viable television genre.
