D-day 





       D-Day is a generic term used by the military to indicate the day when start an attack or a combat operation. Historically, the term used to refer to D-Day June 6, 1944, the day which began operation called Operation Overlord. This operation was to carry out a large landing on the beaches of Normandy as a strategy to end the Second World War, but began at dawning, with the launch of paratroopers belonging to the navy of the United States, they were from the 101st and 82 nd. This day, when the Allied troops penetrated into the French coast, marked the beginning of the liberation of Western Europe occupied by Nazi Germany during World War II. 
     Operation Overlord was the codename for the Allied invasion of northwest Europe. The assault phase, or the establishment of a secure foothold, was known as Operation Neptune. Operation Neptune began on D-Day (June 6, 1944) and ended on June 30, when the Allies had established a firm foothold in Normandy.
    The battle began months before the invasion, more than 300 planes dropped 13,000 bombs over Normandy in advance of the invasion. Six parachute regiments, with more than 13,000 men, also went ahead to cut railroad lines, blow up bridges, and seize landing fields. Gliders also brough in men, light artillery, jeeps, and small tanks.
     The terms D-Day and H Hour are used to mark the day and time at which to start an attack or operation, in circumstances where the date and time have not yet been determined or is absolutely secret. D-Day and H Hour are unique for all units participating in an operation.
      When them were combined with figures and plus or minus signs, these terms indicated a point in time that precedes or follows a specific action. Therefore H-3 means 3 hours before H-hour and D +3 means 3 days after D-Day, H +75 minutes means the time H + 1 hour and 15 minutes.
     The D-Day invasion of Normandy by the Allies was originally set for June 5, 1944, but bad weather and sea conditions, made by General Dwight D. Eisenhower deferred to the June 6, giving them more time to rehearse their acts. Since that date it is popularly known as the small D-Day (In French call or Le Choc JourJ)
      D-Day remains the largest seaborne invasion in history, involving nearly three million troops crossing the English Channel from England to Normandy in occupied France. In this invasion twelve Allied nations provided fighting units that participated in the invasion, including Australia, Canada, Belgium, France, Czechoslovakia, Greece, New Zealand, the Netherlands, Norway, Poland, the United Kingdom, and the United States.
