June 6, 1944: Training for D-Day

“The more you sweat in peacetime, the less you bleed in war.” -Unknown From the moment the last British troops boarded the various civilian craft sent to evacuate them from the beaches of Dunkirk, it was clear that the Allies would have to reinvade Europe at some future date in order to ultimately defeat Germany. Such an operation would require new tactics and doctrine to ensure the success of the effort. Failure to secure a beachhead somewhere on the northwest coast of Europe might doom the Allied hopes of defeating Germany. All military operations carry some risk of failure, but the invasion of could not afford to do so. The Allies could (and would) struggle once they were ashore. They could make grievous errors both before and after the invasion. But once they started landing, there was no margin for error. The landings had to succeed. Which meant the Allies would have to train for them until there was no question they would succeed. In 1941, the United States Army began doing precisely that. The 1st Infantry Division, the Big Red One, began training for amphibious operations, practicing loading and unloading aboard transport ships and disembarking on beaches along the U.S. Atlantic coast. It completed this preliminary training in early 1942 before shipping off to England. While the initial amphibious training it had received gave it a leg up on any other American unit, the U.S. Army still lacked true amphibious doctrine. It began to remedy this in June 1942, with the formation of the First Amphibious Brigade and the 531st Engineer Shore Regiment. However, the Brigade was shipped to England in August 1942, having taken only a few small steps towards developing amphibious doctrine the Army needed to successfully invade Europe. Fortunately, the British were picking up the slack. Immediately following Dunkirk, the British had begun carrying out small raids on the European coast with units that became known as the Commandoes. Using their experiences as a base, the British constructed training centers to disseminate this information to larger units. To its credit, the U.S. Army began taking advantage of these centers quickly, creating an American branch of what the British called Combined Operations and assigning Brigadier General Lucian Truscott to command the U.S. section. Throughout the rest of 1942, American and British units conducted a series of experimental exercises to develop amphibious doctrine as well as helping American and British units learn how to operate together. While the operations were not always successful, they were able to begin the process of developing the critical doctrine the Allies would need to invade Europe. This included the use of specialized assault troops and the development of airborne operations in support of amphibious landings. These lessons would be of significant value on June 6, 1944. American contact with German forces at Kasserine Pass added new urgency to the need for effective training prior to the invasion. Despite a training regimen that would have stood up against any other army’s in the world, the U.S. Army was rudely shocked by Erwin Rommel’s troops, although they were able to recover relatively quickly. But their experience with their first taste of combat demonstrated the need for better training methods to every American general, not least of whom was Dwight Eisenhower. Ike vowed that no unit under his command would stop training until the war was won. From the moment U.S. units arrived in England, they began training. Soldiers trained on the basic soldier skills they would need to succeed. Soldiers spent hours on firing ranges, developing their marksmanship abilities to a fine edge. Physical conditioning was also a major focus. Allied soldiers would not be slowed because they were worn down simply from carrying their own equipment. But there could be no mistake about what they were training for: the invasion. Units trained to assault pillboxes and other fixed installations they could expect to see on French beaches over and over again, using both blank and live ammunition to ramp up the experience to make it as close as possible to the real thing. Units learned how to embark and disembark off of the many landing craft available to the Allies, until they could debark in the shortest possible time. Thousands of men went through the U.S. Assault Training center, which trained units beginning at the individual level all the way through battalion exercises. Then they began assault exercises. In addition to providing what is now known as echeloned training, the training of units at multiple levels concurrently, the assault exercises provided the Allies with valuable experience about what might or might not work in the invasion. Lessons learned were codified into new doctrine and tactics, and then utilized in future exercises to confirm or deny their validity. The training did not come without a price. Operation Tiger, on 27-28 April 1944, saw the deaths of 749 American troops when German E-boats sank two LSTs and damaged six others. Yet even this catastrophe provided important lessons to the Allies, including the need for rescue ships at the beaches and the fact the Americans and British had been operating on different frequencies despite being involved in the same operation. Discovering these flaws had been costly, but resolving them probably saved many other lives on 6 June. Airborne troops didn’t have to worry about capsized landing craft, but instead were making jump after jump into the English countryside. These jumps carried their own risks, from parachutes that failed to open to landing in trees or water. Over and over again airborne units would fall from the sky to begin grueling three-day exercises that forced them to quickly assemble in their drop zones, determine their location, move to their objectives and take them against varying enemy opposition. When Allied soldiers acted on their own or in small groups to disrupt the defending German forces early on June 6th, much of the credit belonged to the commanders who forced them to do so over and over again in the months leading up to the invasion. Other units received more specialized training. Major John Howard’s company prepared for their assault on Pegasus Bridge with six days of training attacking a similar bridge in England under all conditions. The glider pilots conducted some 43 training flights, each more difficult than the last, to ensure they would be able to put their cargos on the ground in the right places when the time came. American Ranger battalions, meanwhile, were learning how to climb sheer cliffs in record time to prepare for their assault on the Pointe du Hoc. And combat engineers were learning about the numerous obstacles that made up Hitler’s Atlantic Wall, to ensure they could breach them quickly and efficiently once they hit the beaches. On D-Day, years of training paid off in every facet of the invasion. Major Howard’s troops landed within a few hundred meters of Pegasus Bridge, thanks to the training of his glider pilots, and his men seized and held the bridge until relieved. American paratroopers, although scattered beyond belief during their drop, found their way to their objectives and ensured that the troops from Utah Beach were able to clear the beach via the causeways across the flooded areas. Rangers scaled the Pointe du Hoc and seized the gun emplacements, only to learn that the guns had never been installed. And the battered and terrified troops on Omaha Beach, despite facing a situation so bad American generals considered abandoning the beach, instead banded together and forced their way off the beach, maintaining the vital link between the American troops at Utah Beach and the British forces. By dusk on June 6th, the Allies were ashore in sufficient force they would not be dislodged. The Germans would fight on for another ten months, but both Allied and German generals knew the truth: with the Allies back in northwestern Europe, the outcome of the war was now a foregone conclusion.

Outstanding and well researched post. Nicely done.

"From the moment the last British troops boarded the various civilian craft sent to evacuate them from the beaches of Dunkirk, it was clear that the Allies would have to reinvade Europe at some future date in order to ultimately defeat Germany. Such an operation would require new tactics and doctrine to ensure the success of the effort. Failure to secure a beachhead somewhere on the northwest coast of Europe might doom the Allied hopes of defeating Germany."

I have some argument here that is, I'm afraid, entirely tangential to the main points of your post.

"...it was clear that the Allies would have to reinvade Europe."

That's not what you mean, at all. You mean "somewhere on the northwest coast of Europe," but, in fact, you seem to specifically imply, by omission, at least, that the only possible strategy was to invade France.

But, of course, we'd already long "invaded Europe." I know you are quite familiar with the terrible long slog up through Italy, after invading Sicily. There were those, of course, including a good deal of the time Churchill, who argued for continuing that push, and refusing the great danger of a cross-channel invasion. They felt no such invasion was either wise, prudent, or necessary.

There had also been fighting in Norway, though obviously one doesn't go very directly to Germany from there.

More to the point, to invade, "somewhere on the northwest coast of Europe," one might just as conceivably go directly into Holland, not France, or perhaps Belgium, to get to Germany. (There were good arguments against that, of course, which is why we didn't do it.)

Most importantly, and I say this with the greatest of respect for all those Allies who fought in the West from D-Day through V-E Day, as well as all those who went before them, D-Day was a side-show. It was not necessary "in order to ultimately defeat Germany."

It was terribly dramatic, to be sure, and one can't over-state that; greatest armada in history, etc.

But not really amongst the top three battles in defeating Germany. Not even likely necessary, save in a political sense.

The Soviet Union had already broken the back of the Wehrmacht at Stalingrad and Kursk. The war for Germany was lost before D-Day. And the entire Western Front was a side-show compared to the East, as we see when we look at the number of divisions involved, and the history of the battles. The Germans were defeated by the Soviet Union, as aided by the West, in essence. Important aid, in innumerable ways, to be sure. Possibly indispensible aid. But nonetheless, it is so.

Lastly, Americans were a minority even in D-Day. The majority of those fighting for the Allies were British and Canadian, over 60%. Yet, somehow, most American coverage tends to leave this unmentioned, or under-mentioned. American coverage tends to present it as a great American triumph, as aided by our compatriots. Which has it reversed in terms of who was actually on the ground, at least, as well as in a considerable number of the technological means invented for the invasion (Mulberry artificial harbors, floating tanks, tanks with flails to beat a path through minefields; all British inventions, not American, though Americans did invent the landing craft).

None of which is to quibble with anything you said, or, of course, implies that in any way we should not honor our D-D veterans, and their sacrifices and victories in the slightest. It just does seem to me to be a bit of necessary context.

I should make clear that what I'm saying here is only about 1% triggered by what you said, which gave credit to the British, and 99% by all the general news coverage of this 60th anniversary, and of general attention paid in popular US accounts; I'm not criticizing you. I'm just venting.

Posted by: Gary Farber at June 6, 2004 08:11 AM

I'm afraid I must disagree with you on multiple points, Gary. First of all, when I said that it was clear the Allies would have to reinvade Europe, that is precisely what I meant. It was not necessarily the case that they would have to invade France; as you note, they first invaded Sicily, and then Italy, and there were arguments in favor of landing in the Balkans, Norway, and even Germany itself. D-Day did not have to be in France, but after analyzing the coast of Europe and noting the Allies' transport limitations, it became clear that France was the logical place to invade. As my post is about the training that the Allies conducted to make the invasion a success, I didn't bother to discuss why the Allies chose to invade Normandy, but since the decision to hit Normandy wasn't made until January 1944, but training for amphibious invasion began in 1941, it seemed logical for me to note only that the Allies quickly recognized that they would have to invade somewhere.

As for D-Day's necessity in defeating Germany, I'm afraid you are incorrect. While D-Day would not have been sufficient without the tremendous damage inflicted on the Wehrmacht by the Soviet juggernaut, had the Allies not landed in France and provided a true Second Front to pull German troops to the West, it is by no means certain that the Soviets could have taken Germany down on their own. By the time of the Battle of Berlin, the Soviets were down to the dregs of their manpower. Had the Germans been able to focus the additional assets they used in the West to confront the Allies, it is quite possible they could have stalemated the Red Army somewhere in Poland. D-Day was a necessary, but not sufficient, element of ultimate German defeat.

Finally, I'm not sure where you get the idea Americans were a minority on D-Day. The invasion involved eight divisions: four American, three British, and one Canadian. When one considers support troops, it is certainly possible that the Americans did not make up 50% of the troops involved, but a rough estimate would make them at least a plurality.

Further, our British friends do much the same in reverse. I've been to the British museum at Arromanche, where you can learn about the brave troopers of the 6th Airborne Division assaulting Pegasus Bridge, the seizure of Bayeux by the 50th Infantry Division, and so on, but very little about what was happening on the east end of the Allied line. C'est la guerre.

"Finally, I'm not sure where you get the idea Americans were a minority on D-Day."

I might have been wrong; I'm somewhat regretting having brought up a petty point. And, of course, it depends upon how and who you count.

Googling around, here we get an authoritative sounding:


Personnel employed in British American Other Allies
Warships 78,244 20,380 4,988
Landing ships, craft and barges 32,880 30,009 —
Naval shore and misc. parties 1,700 2,500 —
Total, Allied navies 170,701

And:


Of the Allied armies, over a hundred and thirty thousand men were landed from the sea on D-day as nearly as can be calculated. Their distribution along the Normandy shore was approximately as follows:

British Sector
American Sector
Gold 24,970 Utah 23,250
Juno 21,400 Omaha 34,250
Sword 28,845 —
Total 75,214 Total 57,500

In addition, over twenty-three thousand airborne troops were landed by the Allied air forces. The records are not complete but, including glider pilots, their approximate numbers appear to have been 7,900 British and 15,500 American.

Those figures may not be reliable, of course, and, as I said, it depends upon who you want to count.

Digression, but this is an interesting little write-up of Operation Tiger that I ran across. Also interesting is the lessons-learned report on the invasion from von Rundstedt at OKW German HQ It's a tad optimistic.

Posted by: Gary Farber at June 6, 2004 07:58 PM

By my math, that still leaves Americans as a plurality: 21,400 Canadians, 61,715 British, 73,000 Americans. A good, multinational effort. John Kerry would have been proud. ;)
