June 6th is widely commemorated as the day in 1944 during World War II when the western Allies invaded Europe, landing on the beaches of the German-held French region of Normandy. From their narrow foothold, they would eventually advance across France, Belgium, the Netherlands, Luxembourg and Germany itself, joining the westward-advancing Soviet army to defeat the once-powerful German military forces. Here are a few links to some historical facts and modern tributes:
