Depending upon how much time you might have spent watching one of the History/Military/Smithsonian channels over the past few days, you know that D-Day was far from a perfectly designed plan, flawlessly executed.
As military planners have known forever; a plan will begin to fall apart just about the time the first attacker meets the first defender.
But, plans have to be made so that participants will understand what was supposed to have happened and they can adjust from that point.
In the case of D-Day, there were years of planning, not just the military actions in North Africa, Italy, then France, but there were years of planning to mine the coal to smelt the iron ore to create the steel to build the planes, vehicles, and ships that would be needed to move the guns, food, fuel, clothing and all the other items that an army needs to function.
Back at home, just about just about every American in every every village and town was in the war. Whether participating in a scrap iron drive, or suffering (with varying degrees of equanimity) with ration coupons for everything from gasoline to condensed milk, American civilians were called upon to help the war effort.
Dwight Eisenhower, the senior American commander in Europe devoted enormous resources to convince the Germans that the invasion would come at Pas de Calais or even Norway and not at Normandy (Operation Fortitude).
Eisenhower used Lt. Gen. George Patton as the decoy building a fake army around him complete with rubber airplanes and tanks, as well as simulated radio traffic to help the Germans believe what they wanted to believe: That Patton would lead the invasion.
At Normandy attacking the beaches was a nearly impossible task. At low tide - necessary so the landing craft could navigate around otherwise submerged obstacles - there was about 300 yards of open beach to be crossed at Omaha.
For those in Washington, DC, that's a little shy of two downtown city blocks. Think about running down the middle of the street from Connecticut Avenue up L Street just about to 19th Street. In sand. In a wet uniform. With machine gunners trying to kill you.
And that was just to get to the sea wall, not beyond the pill boxes.
After enough bodies were thrown against the German defenders the attackers got beyond the Nazi Atlantic Wall and went on to fight through the Norman hedgerow country. Depending upon who is counting, there were some 9,000 casualties among the Allies and, according to Canadian historian Col. C.P. Stacey, that number included about 3,000 deaths.
