Ten years after the close of World War II, the U.S. Navy published a chronology of its operations in the war. Long out of print, the work focused on what were then defined as critical and decisive events. It ignored a multitude of combat actions as well as the loss or damage of many types of U.S. ships and craft—particularly auxiliaries, amphibious ships, and district craft—and entirely omitted the U.S. submarine campaign against Japanese shipping, This greatly expanded and updated study, now available in paperback with an index, goes far beyond the original work, drawing on information from more than forty additional years of historical research and writing. Massive, but well organized, it addresses operational aspects of the U.S. Navy’s war in every theater.
