D-Day : Attack on normandy
On June 6, 1944, 160,000 Allied Troops attacked along a 50-mile stretch of the heavily fortified French coastline to fight Nazi Germany on the beaches of Normandy, France. General Dwight D. Eisenhower called the operation a crusade in which "we will accept nothing less than full victory." More than 5,000 ships and 13,000 aircrafts were a part of the D-Day invasion. By the end of June 6, the Allies gained a foothold in Normandy. The casualties of D-Day was high- more than 9,000 Allied soldiers were killed or wounded, but more than 100,000 soldiers began the march across Europe to defeat Hitler.
The terms D-Day and H-Hour are used for the day and hour on which a combat attack or operation is to be initiated. They designate day and hour for an operation when the actual day and hour have not yet been determined or announced. The letters come from the words for which they stand, "D" for the day of the invasion and "H" for the hour the operation actually begins. When used in combination with figures and plus or minus signs, these terms indicate the length of time preceding or following a specific action. Thus, H-3 means 3 hours before H-hour, and D+3 means 3 days after D-day. H+75 minutes means H-hour plus 1 hour and 15 minutes.
