An Ol' Broad's Ramblings
The short answer: nothing.
In military terms, D-Day and H-Hour are sometimes used for the day and hour on which a combat attack or operation is to be initiated. They are used when the day and hour have not yet been determined, or when secrecy is important.
When used in combination with plus or minus signs, these terms indicate the length of time preceding or following a specific action. Thus, H-3 means 3 hours before H-Hour, and D+3 means 3 days after D-Day. H+75 minutes means H-Hour plus 1 hour and 15 minutes.
“It was cold, miserably cold, even though it was June. The water temperature was probably forty-five or fifty degrees. It was up to my shoulders when I went in, and I saw men sinking all about me. I tried to grab a couple, but my job was to get on in and get to the guns. There were bodies from the I I6th floating everywhere. They were facedown in the water with packs still on their backs. They had inflated their life jackets. Fortunately, most of the Rangers did not inflate theirs or they also might have turned over and drowned.
I began to run with my rifle in front of me. I went directly across the beach to try to get to the seaway. In front of me was part of the II6th Infantry, pinned down and lying behind beach obstacles. They hadn’t made it to the seaway. I kept screaming at them, ‘You have to get up and go! You gotta get up and go!’ But they didn’t. They were worn out and defeated completely. There wasn’t any time to help them.
I continued across the beach. There were mines and obstacles all up and down the beach. The air corps had missed it entirely. There were no shell holes in which to take cover. The mines had not been detonated. Absolutely nothing that had been planned for that part of the beach had worked. I knew that Vierville-sur-Mer was going to be a hellhole, and it was.” (Read the entire account here.)
