A World War II map shows the two areas where the Germans were setting up their secret "V" weapons to bombard England (right, center). These are the areas in which the Royal Air Force and 8th Air Force heavy bombers concentrated their bombs in order to knock out the weapons -- part of the pre-invasion plan. This event was given the operational code name Crossbow during World War II. The grouping (left, center) is the site of the Invasion of Normandy.
