Dupuy on D-Day

A LCVP from the U.S. Coast Guard-manned USS Samuel Chase disembarks troops of Company E, 16th Infantry, 1st Infantry Division (the Big Red One) at the Fox Green section of Omaha Beach on the morning of 6 June 1944. American soldiers encountered the newly formed German 352nd Division. During the initial landing, two-thirds of Company E became casualties.

Today is the 75th Anniversary of D-Day, the invasion of Normandy by U.S., British, Canadian and other allied forces. The American who announced the D-Day invasion on Tuesday, 6 June 1944 was the journalist, soldier and historian, R. Ernest Dupuy (1887-1975) of New York. The announcement from SHAEF can be heard here (Dupuy’s announcements starts at 2:00): https://www.youtube.com/watch?v=K9xk9GaV0NE

Under the command of General Eisenhower, Allied naval forces, supported by strong air forces, began landing Allied armies this morning on the northern coast of France.

He was the father of Trevor N. Dupuy, the founder of The Dupuy Institute.

  1. At one point we were discussing trying to do a definitive book on the campaign, but never did. Richard C. Anderson did write “Cracking Hitler’s Atlantic Wall: The 1st Assault Brigade Royal Engineers on D-Day.”

    • “At one point we were discussing trying to do a definitive book on the campaign, but never did.”
      You should do!

      • Well, most of our research efforts have been done under contract with the U.S. government (for example, Ardennes Campaign Simulation Data Base, Kursk Data Base, our urban warfare studies, etc.). Properly researching the Normandy campaign would take several man-years of effort. Hard to do that without some budget.

        • Oh well, hopefully you will get the call one day, whether from a government or an interested billionaire…

          • Well, rarely does anyone actually fund research into military history. The reason we were able to extensively research the Battle of the Bulge and Kursk was because Army operations research community needed databases for combat model validation.
