Do not let the otherwise bland title fool you. Nearly seven decades after the Allied landings in northern France, this service history remains the most comprehensive study of the maritime side of the invasion of Normandy.
Covering the complete history of the operation, from its early planning stages in January 1942 until its execution 30 months later, this is an exhaustive study of what had to happen behind the scenes in order to bring together the massive flotilla necessary to make D-Day happen. It is probably one of the best yet least told naval stories of World War II, and it is available for free reading online.
The work itself has, to my knowledge, never been published in book form, though the original manuscript was apparently a key source for naval Historian Samuel Eliot Morrison when he wrote the eleventh volume in his massive operational history of the U.S. Navy in World War II. This it is probably the single best primary source of history about the operation.
A must for any historian, we can only hope that somebody will put it in book, pdf, or Kindle format at some point soon.
