History focused its sights along the coasts of Normandy at 6:30 am on June 6, 1944, as the 135,000 men and 20,000 vehicles of the Allied forces made land in their first incursion in Europe in World War II. The entire operation on this "Longest Day" was called Operation Overlord—the code name for the invasion of Normandy. Five beachheads (dubbed Utah, Omaha, Gold, Juno, and Sword) were established along the coast to either side of Arromanches. Preparations started in mid-1943, and British shipyards worked furiously through the following winter and spring building two artificial harbors (called "mulberries"), boats, and landing equipment. The British and Canadian troops that landed on Sword, Juno, and Gold on June 6, 1944, quickly pushed inland and joined with parachute regiments previously dropped behind German lines, before encountering fierce resistance at Caen, which did not fall until July 9.
