There’s an article in my newspaper today about the wall map that was used to plan the landings. Chad Valley, a British toy maker, was commissioned to make a huge map covering all of Western Europe. A carpenter was then brought in to cut out the Normandy section and to fix it to the wall in Eisenhower’s HQ. He was then detained, I hope in some comfort, until September. An electrical engineer brought in to repair an electrical connection in the room was also detained. They thought of just about everything.
