When I think of Christmas, I think of the Normandy Invasion, commonly known as D-Day. Years of planning went into that event. First, and the most obvious, was physically amassing the men and equipment needed to pull off the invasion. Hundreds of thousands of soldiers, landing boats, airplanes, troop transports, weapons and ammunition, communication devices, food, and medical supplies all were assembled despite the threat of German U-boats that were intent on preventing the invasion.
Then there was the element of strategy. How could the Allies pull off a surprise invasion when the Germans knew that it would happen and would fortify the likely landing zone? We know now that the Allies used quiet gliders under the cover of darkness to allow the paratroopers to drop in behind the German fortifications and take the battle to them from both sides. Our leaders created a unique communication device—a clicker—so that the paratroopers could communicate with one another in the dark. They also used the Navajo language to securely communicate information because of the difficulty of breaking this code.
Finally, there was the sacrifice. The loss of life would be great; the human suffering would be greater. But the goal of freedom required it.
