This volume investigates the strategic and tactical maneuvers of the United States Navy during the initial phase of the Pacific War against the Empire of Japan. Samuel Eliot Morison, appointed by President Franklin D. Roosevelt to document the naval history of the conflict, utilizes official records, personal logs, and interviews with commanding officers to construct a comprehensive account. The work argues that the rapid mobilization and adaptation of naval forces were critical in halting Japanese expansion despite early catastrophic losses. It provides a foundational framework for understanding the transition from defensive posturing to offensive naval operations in the Pacific theater.

Historians and naval experts regard this series as the definitive, albeit official, record of United States naval operations during the Second World War. Readers frequently note the academic density of the prose and the meticulous attention to operational detail provided by the author.
