D-Day: Background & Overview

(June 6, 1944)

The plans to invade Nazi-occupied Europe through the beachheads of France sat in front of General Eisenhower. On the evening of June 5, 1944, the wind was blowing at 15 to 20 knots and six-foot waves were roiling the ships, but the Royal Air Force (RAF) predicted the skies would be clear the next day. Conferring with his colleagues, Eisenhower got conflicting advice - Generals Bradley and Montgomery wanted to go ahead; the Air Force and Navy generals preferred to wait.

After a few moments of deliberation, Eisenhower said three words that would change history: “Okay, let’s go.”

- Attacking France
- Omaha Beach
- Gold Beach

Attacking France

On the morning of June 6, 1944, Eisenhower released the following order, alerting the Allied armies of the green light for war:

“Soldiers, sailors, and airmen of the Allied Expeditionary Force! You are about to embark upon the Great Crusade, toward which we have striven these many months. The eyes of the world are upon you. The hopes and prayers of liberty-loving people everywhere march with you.”

With General Eisenhower's go-ahead, the BBC broadcast a coded message that instructed members of the French resistance to cut railway lines throughout the country. Nearly all of those targeted were successfully severed.

The attack began with more than 1,000 RAF bombers attacking coastal targets. This attack was followed by 18,000 paratroopers being dropped inland to capture key bridges and roads and cut German communications. The British Sixth Airborne Division suffered few casualties and succeeded in capturing bridges at the Orne River and the Caen Canal.

The Americans had a harder time. Their 101st and 82nd Airborne Divisions missed their drop zone and were scattered. Many men drowned when they landed in the water. The dispersion of the Americans helped confuse the Germans, but it also meant that troops who survived the jump (and many didn’t) were isolated and easier to kill or capture. But in the end, they played a major role in the securing of Normandy by opening the way inland for the infantry, destroying much of the German artillery aimed at the beaches, and blocking avenues for potential counterattacks. Dying was not a danger for the dummy paratroopers — literally dolls dressed up like soldiers — that were also dropped away from Normandy to deceive the Germans as to the location of the attack.

Minesweepers cleared lanes in the English Channel for the transports. The beaches were 60 to 100 miles away when the armada of nearly 7,000 ships left from ports such as Portsmouth, Southampton, Chichester, and Falmouth. Soon that 100 miles would be covered with 59 convoys that included 4,000 landing craft, 7 battleships, 23 cruisers, and 104 destroyers.

German torpedo boats out of the port at Le Havre were the first to encounter the Allied forces, but they were quickly driven off. Having spotted the invasion fleet, German coastal batteries began firing at the approaching ships. At the same time, Allied warships began bombarding the beaches, destroying bunkers, setting off land mines, and destroying obstacles in the path of the landing parties.

To prepare for the landing of troops, the air force and navy bombarded German positions, and continued their attacks throughout the day. Meanwhile, paratroopers blocked any potential counterattackers and knocked out the artillery batteries that covered the beach.

The first troops hit the beaches about 6:30 A.M., with 23,000 men rushing onto Utah Beach. Though certainly scared to enter combat, which most were facing for the first time, the soldiers were so terribly seasick from the rough crossing that they were actually anxious to get off the boats.

“We want this war over with. The quickest way to get it over with is to go get the bastards who started it. The quicker they get whipped, the quicker we can go home. The shortest way home is through Berlin and Tokyo. And when we get to Berlin, I am personally going to shoot that paper-hanging son-of-a-bitch Hitler.”

— General Patton, Speech to the Third Army (June 5)

Almost nothing went according to plan. Few of the landing craft arrived at the time they were supposed to, and none placed their troops at the designated target. The landing craft were buffeted by wind and waves and had to evade a network of thousands of mines, which sank several of the ships that were assigned to guide those that followed.

General Theodore Roosevelt, Jr., the son of the former president, was one of the first ashore. He had lobbied to lead his troops in to boost their morale, but had a tough time persuading his superiors to let him go. Besides his rank and lineage, Roosevelt had a heart condition and walked with a cane, but he would not be deterred from the mission. Looking every part the Hollywood commander— Roosevelt did not bother with a helmet, he wore a wool-knit hat instead— he ignored the shooting around him and calmly walked across the beach to huddle with commanders. Since the invasion force had landed in the wrong place, they had to decide whether to stick to the original plan and have the remaining troops try to land in the target area or improvise and head inland from where they were. Roosevelt is said to have made the decision, “We’ll start the war from right here.”

Most of the German defenders (many of whom were not German, but soldiers forced into the army from occupied countries) either surrendered or withdrew inland. The American forces quickly secured the area and, within a few hours, supplies and additional troops were also coming ashore. Soon the biggest problem for the Americans at Utah was managing the traffic jam of men and material.

Omaha Beach

Rommel knew that if an attack came at Normandy, at least part of the invasion force would try to land on the sandy beach the Allies designated as Omaha. This beach was the largest landing area (six miles) and the most vulnerable: 100-foot nearly perpendicular cliffs overlooked the beach. To prepare for a possible attack, the Germans had mined the waters offshore, littered the beach with obstacles, and placed heavy guns on the cliffs overlooking what amounted to a shooting gallery below. And, in fact, when the defenders saw the first landing parties, they thought they were crazy.

American soldiers landing at Omaha Beach

The Allies were confident that the air and naval bombardment would soften up the defense, that the German soldiers would be from a low-quality division, and that the 40,000 troops assigned to take the beach would overwhelm the defenders. Instead, the defensive force the Americans confronted, an elite German infantry division, was far stronger and better trained than expected. Heavy clouds protected the German defenders from Allied bombers, who dropped their payloads in fields beyond the beachfront, and the poor visibility also prevented offshore guns from initially offering much support.

With the exception of one unit, the wind and tide caused the landing craft to miss their objectives. Instead of distributing troops across the beach, they landed in bunches that became easier targets for the German gunners. Many soldiers were killed before they could fire a shot in the war. More than two-dozen of the special amphibious Sherman tanks made for the invasion immediately sank upon debarking the transports, taking their crews to the bottom. These were just a fraction of the hundreds of vehicles of all types that never reached the beach or were destroyed soon after they got there. Instead of 2,400 tons of supplies being brought ashore, only 100 tons made it.

In writing, much of the fighting can only be described in a sterile fashion that doesn’t capture the horror of combat. Omaha Beach was as hellish as any battle of the war. The first landing parties, seasick from the rough crossing, were literally ripped apart by mines, artillery, and machine-gun crossfire.

Many soldiers drowned in deep water before their craft were close enough to the beach. Others struggled even in shallower water, fighting the tide and the burden of carrying packs and guns, wearing heavy boots and steel helmets, and then adding the additional weight of their drenched uniforms. Helpless in the water, still more men were killed before they could stagger ashore. The noise was deafening, and the cries of the wounded sickening. The beach offered no cover, the only place to go was forward, and the chances of making it across in the early stages were practically zero. Waves of landing craft continued to drift ashore, many exploded by shells or mines, and the numbers of Allied soldiers and casualties piled up. The veterans of the landing on Omaha would later reminisce that it was a miracle they managed to get on the beach, let alone survive on it or advance beyond it.

Given the enormous naval armada offshore and the Allied dominance of the air, it is reasonable to ask why the German forces couldn’t have been decimated by strafing planes, bombers, and shells from the navy’s big guns. Those assets did not play as large a role as they might have for several reasons. Perhaps the most important is that once the soldiers were on the beach, neither the air force nor the navy had the accuracy to hit only the enemy targets, and it was feared that too many friendlies could be hit by accident. The navy provided invaluable support, but it was limited because so many radios were lost or disabled in the landing that troops on the beach could not communicate with the ships and direct their fire. The air force ensured the Germans couldn’t put planes in the air to harass or otherwise threaten the invasion, but Allied planes couldn’t support the fight on the beach; their main contribution would be in destroying targets inland that would help the advancing troops after they got past the beaches.

The landing stalled and the order was given to cease landing. General Bradley thought the landing had been a disaster and the troops might have to withdraw. All organization fell apart as soldiers, boats, and bodies jammed the single narrow channel engineers were able to clear among the German mines and obstacles. Trapped behind a low shelf halfway across the beach, under withering German fire from above, isolated groups and individuals with no choice but to get off the beach gradually fought their way forward and eventually took key points at each end of the beach. It took several hours, and heavy navy bombardment, to secure the beachhead, as well as a courageous effort by Army Rangers, men of C Company, and the 116th regiment to scale the surrounding cliffs with rope ladders to take out the guns guarding the coast.

Gold Beach

The British troops landed at 7:20 on Gold Beach, where their experience was completely different from that of the Americans at Utah and Omaha. Unlike those landed sites, the British had little actual beach to cross. Once they surmounted the seawall and an antitank ditch, they were into villages with pave streets. Beyond the villages were mostly large wheat fields. They also faced almost no enemy fire and had an orderly landing that went largely according to plan. A total of 25,000 troops stormed Gold at a cost of 400 casualties. By the end of the day, the British had advanced five miles beyond the coast.

A Canadian force was assigned the task of taking Juno beach. This all-volunteer force was well-trained and highly motivated because of a desire to avenge a disastrous defeat during the attempted assault on the port of Dieppe in August 1942.

As in the case at the other landing sites, the Canadians expected the defense to have been significantly degraded by air force bombing, but despite the heaviest bombardment of the war during the hours preceding the invasion, not a single fortification on Juno was destroyed. Still, the 2,400 Canadians who came ashore overwhelmed the 400 German defenders, who were not front-line troops, but mostly Poles and Russians who had been forced to serve a regime they did not believe in.

Sword Beach

While much of the preinvasion actions designed to knock out German defenses and make the beach landings easier did not go according to plan, the airborne plan to take out the German guns covering Sword beach did succeed. Not all the guns were taken out, and the invasion force did face formidable mine fields, antitank ditches, and other fortifications, but the paratroops did succeed in significantly degrading the enemy defenses. This allowed 29,000 British soldiers to storm the beach at a cost of 630 casualties. As in the case of the other beaches, the troops overcame the initial defense and then began to move inland, but failed to get as far as the D Day planners had hoped.

By 10:15 A.M., Rommel had learned that the Allies had landed and rushed back to France. Hitler had ordered him to drive the invaders back into the sea, but still had not given him the military resources he needed to do so. One of the strongest panzer divisions, equipped with new, state-of-the-art Tiger tanks, was sent to reinforce the defenders at Normandy, but its trip from Toulouse was repeatedly delayed through the sabotage efforts of British agents and French partisans, who turned what should have been a 3-day race to the front into a 17-day crawl.

Another panzer division tried to split the British and Canadian forces by shooting through the gap between Sword and Juno. Had it succeeded in reaching the sea, it might have caused serious trouble, but the British were able to neutralize the German force before it could do any serious damage.

In the terrifying first hours making their way under fire from the stormy sea to shore, across a front of more than 50 miles, the Allies suffered surprisingly few casualties. On that first day, roughly 175,000 soldiers had come ashore and approximately 2,500 had been killed. The Americans had suffered the fewest casualties (dead or wounded) on Utah Beach, approximately 300, but also the most, 2,400 (our of 40,000 who went ashore), on Omaha. In the first two days, the number of men and vehicles the Allies got across the Channel was well below what was planned; still, Eisenhower was happy the deception had worked, and the Germans were unable to stop them on the beaches.

Once the initial assault succeeded, the Allies had an opportunity to press their advantage and exploit the Germans’ confusion, but they did not advance as far as expected. In fact, the deepest penetration, by the Canadians at Juno, was only about six miles. Besides German opposition, one of the principal reasons the penetration was not greater was that soldiers felt so satisfied with what they’d just accomplished — and thankful that they had survived.

Hitler's Mistakes

The Germans had made numerous fatal miscalculations. The most important was their conviction that the invasion would be elsewhere, so they were caught by surprise at Normandy. At the end of D Day, most of their forces were still arrayed in preparation for an invasion at Pas-de-Calais.

General Jodl believed it would take the Allies as long as a week to put three divisions into France, but the Americans had accomplished this on Utah beach alone in a single day. Communication was poor, so the Germans were confused throughout the attack as to exactly what was happening where and Rommel, the architect of the defense plan, was in a car driving through France and incommunicado during several crucial hours.

As in the case of the Eastern Front, the German high command was also hamstrung by Hitler’s distrust of his generals and their fear of acting without his approval. This proved disastrous on D Day when Rundstedt ordered two panzer divisions to Normandy, but first requested Jodl’s approval. Jodl told Rundstedt Hitler was sleeping. No one had the courage to wake Hitler for approval and since he slept in that day, the tanks were not moved into position.

The Germans also made the mistake of trusting their own version of the Maginot Line, the Atlantic Wall, to stop the Allied invasion rather than the deployment of their best troops. They had indeed erected a formidable defense of trenches, mines, barbed wire, and other obstacles, but it took the Allies less than a day to breach it, and then the “wall” was useless.

Rather than assign their crack troops to protect the wall, the Germans had also decided to hold them in reserve or had them deployed elsewhere. Instead, they relied on poorly trained conscripts and POWs from territories they’d conquered who had little or no motivation to fight for Hitler, and were no match for the Allied troops who were superbly trained and believed they were fighting to keep the world free.

Monitoring German military messages after the invasion, the British picked up the crucial piece of information that the Luftwaffe was dangerously short of aircraft fuel. Knowing this, war planners made Germany’s synthetic oil factories their top priority for air strikes as soon as Overlord could spare the planes.

Within a week, American and British forces linked up, clearing the beachheads. With this done, the Seventh Corps, under Major General J. Lawton Collins, moved on Cherbourg and took the city on June 27. This port was meant to receive men and supplies, but it took several weeks for the damage to be sufficiently repaired. The delay was a factor in stalling the later offensive, but once the port was fully operational, it was the entry point for more than half of all American supplies sent to France.

The victory at Cherbourg was important for demoralizing the Germans, particularly after Hitler had ordered the port held at all costs. Afterward, Rommel and von Rundstedt went to see Hitler, to ask again for more troops and equipment, and to find out how he intended to win the war. Hitler’s reaction was to deny the requests, sack von Rundstedt, and replace him with Field Marshal Gunther Hans von Kluge.
