Codename Operation Overlord
“You are about to embark on the great crusade toward which we have striven these many months. The eyes of the world are upon you… I have full confidence in your courage, devotion to duty and skill in battle”. – Gen. Dwight D. Eisenhower –
Operation Overlord is the operation of the liberation of German-occupied northwestern Europe from German control in Normandy. The assault phase of Operation Overlord was known as Operation Neptune. This operation involved landing the troops on the beaches, and all other associated supporting operations required to establish a beachhead in France. By this time, the Allies had established a firm foothold in Normandy. Operation Overlord also began on D-Day, and continued until Allied forces crossed the River Seine on 19 August 1944. The Battle of Normandy is the name given to the fighting in Normandy between D-Day and the end of August 1944. The date when Paris was liberated, 25 August 1944, is sometimes used as the end of the Battle of Normandy.
May 1944 had been chosen at the conference in Washington in May 1943 as the time for the invasion. Difficulties in assembling landing craft forced a postponement until June, but June 5 was fixed as the date by Eisenhower on May 17. As the day approached and troops began to embark for the crossing, bad weather set in, threatening dangerous landing conditions. Eisenhower and his subordinates decided on a 24 hour delay. Eventually, on the morning of June 5, Eisenhower “OK We will go.” After consulting the weatherforecaster. Within hours an armada of 3,000 landing craft, 2,500 other ships, and 500 naval vessels, escorts and bombardment ships began to leave English ports. That night 822 aircraft, carrying parachutists or towing gliders flew to their designated Normandy landing zones.
Over 425,000 Allied and German troops were killed, wounded or went missing during the Battle of Normandy. This figure includes over 209,000 Allied casualties, with nearly 37,000 dead amongst the ground forces and a further 16,714 deaths amongst the Allied air forces. Of the Allied casualties, 83,045 were from 21st Army Group (British, Canadian and Polish ground forces), 125,847 from the US ground forces. The losses of the German forces during the Battle of Normandy can only be estimated. Roughly 200,000 German troops were killed or wounded. The Allies also captured 200,000 prisoners of war (not included in the 425,000 total, above). During the fighting around the Falaise Pocket (August 1944) alone, the Germans suffered losses of around 90,000, including prisoners. During the battle, between 15,000 and 20,000 French civilians were killed, mainly as a result of Allied bombing. Thousands more fled their homes to escape the fighting.
“An operation of the nature and size of Operation Overlord has never been attempted in history.”

Codename Operation Neptune D-Day-0
“Les sanglots longs des violons de l’automne / Blessent mon cœur d’une langueur monotone.”
Part of a song (chason) from Paul Verlaine. These were the 2 lines for the French resistance to prepare for an Allied invasion. The start of D-Day!
Operation Neptune is the name of the biggest seaborne invasion the world has ever seen. It was on Tuesday, 6 June 1944 on the coast of Normandy. It was the beginning of Operation Overlord.
It was plannend to secure a stable position for more Allied troops on the mainland of Normandy. This day is also known as D-Day (military term). In total 156,000 Allied troops landed along a 60-mile stretch of heavily fortified French coastline called the Atlantikwall on D-Day. With nearly 5,000 landing and assault craft, 289 escort vessels, and 277 minesweepers participating.
The first Allied action of D-Day was Operation Deadstick, a glider assault at 00:16 at Pegasus Bridge over the Caen Canal and the bridge (since renamed Horsa Bridge) over the Orne, half a mile (800 metres) to the east. Both bridges were quickly captured intact, with light casualties, by members of the British 5th Parachute Brigade and the 7th (Light Infantry) Parachute Battalion. The five bridges over the river Dives were destroyed with minimal difficulty by the 3rd Parachute Brigade.
The American airborne landings in Normandy were the first American combat operations the invasion of Normandy by the Western Allies on June 6, 1944, during World War II. Around 13,100 American paratroopers of the 82nd and 101st Airborne Divisions made night parachute drops early on D-Day, June 6, followed by 3,937 glider troops flown in by day.
Operation Neptune began on D-Day 6 June 1944 and ended on 30 June 1944.
The Allied Command had devided the beaches in 5 major sectors.
SWORD BEACH (BRITISH)
At the east of the landing D-Day beaches, with sectors O, P, Q, and R. Like all the British or Canadian beaches, Sword was fronted by vacation homes close to the sea wall. At Ouistreham some of the houses had been reinforced and turned into makeshift bunkers. An antitank ditch had been dug behind the seawall, but paved city streets lay beyond, some blocked by concrete walls. To the east was the Merville battery of four 75 mm guns. Within supporting range were 155 mm guns at Le Havre.
GOLD BEACH (BRITISH)
A ten-mile stretch between Omaha Beach to the west and Juno to the east, Gold was divided into sectors H, I, J, and K, with the main landing areas being Jig Green and Red plus King Green and Red. It was one of the largest of the D-Day beaches. Gold was assaulted by the British Fiftienth (Northumberland) Infantry Division and 47 Royal Marine Commando in the Item sector. Two good-sized towns fronting Gold Beach were La Rivère and Le Hamel, but the major objective was Arromanches at the west end, selected as the site of one of the Mulberry piers, meant to improve Allied logistics as soon after the landings as possible.
JUNO BEACH (Canadian)
Smallest of the D-Day beaches, Juno covered two miles between Gold Beach to the west and Sword to the east. Its three sectors were designated L, M, and N. The primary sectors were Nan Red, White, and Green to the east and Mike Red and White to the west.
OMAHA BEACH (US)
Omaha was the most heavily defended of all the D-Day beaches. Omaha spanned ten statute miles in seven sectors A, B, C, D, E, F, and G, bounded by the Douve Estuary separating Utah Beach on the west and by Gold on the east. Before the landingcrafts touched shore, the area was attacked by hundreds of bombers but their bombs fell too far inland. Forced to drop through an undercast, the bombers were concerned about ‘‘overs’’ that might endanger the naval force offshore. Consequently, no German defenses were damaged, and no bomb craters were available to provide cover for the GIs on the beach. At the end of the day the US forces that landed sufferd 3000 casualties of whom c 1000 died. The beach was also known as ‘Bloody Omaha’.
UTAH BEACH (US)
The most westerly sector of the D-Day beaches. Extending some eleven statute miles in four sectors S, T, U, and V running north-northwest to south-southeast. Utah joined the west end of Omaha Beach in a line projecting through tidal flats beyond the mouth of the Vire River.
POINTE DU HOC (US)
Pointe du Hoc, a prominent headland situated between Utah and Omaha, was assigned to two hundred men of 2nd Ranger Battalion, commanded by Lieutenant Colonel James Rudder. Their task was to scale the 30m (100ft) cliffs with grappling hooks, ropes, and ladders to destroy the coastal gun battery located at the top. The cliffs were defended by the German 352nd Infantry Division and French collaborators firing from above.

Casualties on D-Day-0
In April and May 1944, the Allied air forces lost nearly 12,000 men and over 2,000 aircraft in operations which paved the way for D-Day.
Historian Joseph Balkowski, who lists casualties unit-by-unit, gives these casualty figures:
– Utah Beach: 589, including 197 killed.
– US airborne landings: 2,499 including 238 killed.
– Other Allied: 235 naval and 340 air casualties.
– Omaha Beach: US Army: 3,686 casualties.
– Other Allied: 539 naval and 10 air casualties.
– Gold Beach 1,023,
– Juno Beach 1,242,
– Sword Beach 1,304
– Losses amongst the British airborne troops are often quoted as some 600 killed or
wounded, and 600 missing; 100 glider pilots also became casualties
– The total German casualties on D-Day are not exacly known, but are estimated as being between 4,000 and 9,000 men
– Naval losses for June 1944 included 24 warships and 35 merchantmen or auxiliaries sunk, and a further 120 vessels damaged.
The US National D-Day Memorial Foundation has achieved an accurate figure for the Allied personnel who were killed on D-Day. They have recorded the names of individual Allied personnel killed on 6 June 1944 in Operation Overlord. So far they have verified 2,499 American D-Day fatalities and 1,914 from the other Allied nations, a total of 4,413 dead (much higher than the traditional figure of 2,500 dead). Further research may mean that these numbers will increase slightly in future.
