D-Day

Heavy German machine guns and mortar fire...

Patton was given command of a fake army to confuse German spies as to where the invasion was going to take place. Patton's intent was to make them think of Calais as the target. It apparently worked as the Germans strengthened troops in Calais area.

24 hours = 1 day
48 hours = 2 days
72 hours = 3 days

(1 PM Friday) + (3 days) = 1 PM Monday

D-day was the code name chosen for the invasion of France by the Allies during WWII. It meant the day that the invasion operation was to take place. The following days would be D-day plus one, D-day plus two, and so on.

You would really have to re-define that question to get an answer you want.
On D-Day itself, 6th June 1944, 1,465 American troops lost their lives. D-Day was ONLY the 6th June. Subsequent days were known as D+1, D+2 and so on. The beaches were used for continued landings for almost a month before European ports came into use. Each day more American servicemen lost their lives, but this was not strictly D-Day if it happened after 6 June.

Admiral Sir Bertram Ramsay was a senior officer in the Royal Navy who was Allied Naval Commander for the invasion of Normandy.

D-Day was the military code name for the first day of the invasion of Normandy during WW 2. -This first day was a vital part of Operation Overlord, to re-establish freedom in Europe. On D-Day the Allies managed to land over 170,000 soldiers with thousands of vehicles and supplies. This continued on a lesser scale for almost 4 months.

By mid 1944 the Luftwaffe had been severely reduced by Allied bombing attacks on airfields, aircraft production factories and refineries. By June the Luftwaffe was extremely low on aircraft, parts and aviation gas.

He announced that the allied invasion of France had begun.

D day was fought in Normandy and started when the Americans had stormed Normandy beach.

An estimated 156,000 allied troops landed in Normandy on D-Day in 1945.

Most of the German generals had no plan for the invasion of Normandy. They were almost all fooled by the Allied strategy of building a fake army in Norfolk, apparently to attack Calais,far north of Normandy. Rommel was the only senior German who anticipated the attack in Normandy and he couldn't persuade his superiors of this. The heavily armed Omaha Beach was a product of Rommel's ingenuity.

it put allied forces back into Europe in order to defeat the Germans.

General Dwight D. Eisenhower

Approximately 20,000 men parachuted into France starting about 6 hours before the seaborne landings.

British casualties on D-Day have been estimated at approximately 2700. "Casualties" refers to all losses suffered by the armed forces: killed, wounded, missing in action (meaning that their bodies were not found) and prisoners of war. There is no "official" casualty figure for D-Day.

Sort of, British deceptions had convinced the Germans that the Allied invasion would take place at Calais and Rommel built up defences in the "wrong" places because of that - even after the Normandy landings the German high command believed that was a diversion for the "real" invasion which would come later.
