Blitzkrieg: How Nazi Germany Crushed France in World War II

The German concept of mobile warfare was conclusively proven when the Wehrmacht breached the French defenses at Sedan in May 1940.

The attack was beginning despite the widespread lack of artillery support, engineers, or armor. Normally this would be a recipe for disaster. Clusters of gray-clad German infantrymen braved the torrent of enemy fire, carrying assault boats right up to edge of the Meuse River. On the opposite bank, French soldiers crouched in their bunkers and trenches as German aircraft roared overhead, bombing and strafing, paying particular attention to the French artillery positions within range of the river. The Luftwaffe pilots were determined to keep French heads down with a storm of bombs and bullets. Men on both sides braved fire to accomplish their respective missions on the afternoon of May 13, 1940.

On the German side of the river, Lt. Col. Hermann Balck urged his men forward. His command, Panzergrenadier Regiment 1 of the 1st Panzer Division, was tasked to get across the river and establish a bridgehead. The situation was already unfolding against his unit. Earlier in the day, the least German movement drew artillery fire, keeping the German troops pinned in their hastily dug foxholes and entrenchments. Their own artillery was hopelessly mired in a traffic jam rearward and could not get there in time. The boats for the crossing had arrived, but the operators had not. The only thing that had gone right was the Luftwaffe’s air attack. The aviators’ efforts had been so successful the French gunners had reportedly abandoned their guns and refused to return to them.

It was here that Balck’s meticulous training and leadership came into play. He had trained his men to operate the boats themselves, planning against just such an occurrence. Now he did not have to wait. The French artillery’s cessation had an immediate effect on his men. Just minutes earlier they were lying in slit trenches, trying to avoid the maelstrom of steel flying mere inches above them. Now they leaped from cover and got the boats into the water. Ordering his regiment to cross the Meuse, Balck climbed into a boat, set on accompanying the first wave.

The German troops huddled in the fragile inflatable boats; they were at their most vulnerable point with nothing to protect them from enemy fire. Bullets fell like hail. Balck, always one to lead from the front, impressed his men by his willingness to share the risks of combat. It would enable him to get the most out of them now and in the future. Today, however, the crossing was quick as the Meuse is only a few hundred feet wide.

It took only minutes for Balck and his men to scramble ashore while the boats returned for the second wave. The Panzergrenadiers hurriedly attacked the first line of bunkers nearest the riverbank. Within a short time they carved out a small perimeter and steadily began to expand it. The battle for Sedan was well underway; its outcome would soon decide the fate of France itself.

The blitzkrieg legend has stayed with the German Wehrmacht to this day. The term itself was made famous by the Western press; the Germans referred to the concept as bewegungskrieg, or war of movement, only rarely using the term blitzkrieg at the time. Nevertheless, the word has gained common usage since and there is no better example of it than the Battle of Sedan in 1940. It was a critical point in the Nazi invasion of Western Europe; if the Germans were held up here it could have fatally doomed the entire effort into stalemate. Success would mean victory and revenge over hated France, which imposed harsh terms at the end of World War I.

 

Both France and Britain entered the war just days after the Third Reich attacked Poland on September 1, 1939. The war since then had been marked by a lack of combat in the West. British pundits labeled it the “Sitzkrieg” due to the inactivity. An American senator called it the “Phony War.” This low tempo was just what the Nazis needed; they were unprepared to fight a two-front war, and their western defenses were manned by underequipped second-rate troops. They did not waste this precious time but instead began planning their campaign to knock France out of the war. With luck, this would cause Britain to negotiate, leaving Germany in control of mainland Europe.

The German plan was the brainchild of General Erich von Manstein. He was unhappy with the existing plan, which he feared would not achieve the fast, decisive victory Germany needed. It called for one army group to demonstrate in front of the Maginot Line to keep the force occupying it in place. A second group would advance through the Ardennes region and southern Belgium, acting as a pivot point for the main effort, an attack by a third group that would sweep through the Netherlands and northern Belgium to drive the Allies back until the Channel ports were captured. To Manstein, this was an unimaginative repetition of the World War I Schlieffen Plan, which ultimately ended in four years of stalemated trench warfare.

 

Instead, Manstein devised a plan that could trap the Allies away from their lines of communication and end the war quickly. His plan also involved three army groups. Army Group C would still attack the Maginot Line to keep the troops manning it focused away from the real action. Army Group B would invade Belgium and the Netherlands using a large number of airborne troops and just enough armored divisions to make it look like the main thrust was occurring there. This would hopefully draw the Allies’ main armies north into Belgium. In actuality, this was just what the French expected to happen. Army Group A, with the bulk of the tank and mechanized units, would be the primary force. It would attack through the Ardennes Forest, which was thought impassable to heavy forces. Once through, it would quickly cross the Meuse River and strike for the English Channel coast. This would cut off the Allied armies in Belgium and place them in a position to be annihilated if they would not surrender.

Army Group A would send its best units through the Ardennes first in the hopes they would quickly get to the Meuse River, crossing it between Sedan and Namur. This included the panzer divisions supported by motorized infantry units of both the Heer (Army) and Waffen SS. If they could get across the river quickly, it would allow the Germans to get behind the French lines and make their break for the coast. It was difficult but not impossible. The roads through the Ardennes were narrow, and only a few of them ran east to west. Moving so many divisions through the area quickly would require using both lanes of each road for westbound traffic. Even worse, the units would have to abandon the usual rules for spacing; they would be packed together almost bumper to bumper, making them vulnerable to air attack. To offset this risk the Luftwaffe would deploy much of its fighter strength over the area to beat back any Allied air attacks. Likewise, large numbers of antiaircraft guns would accompany the advancing German columns.

Among the subunits of Army Group A was the XIX Panzer Corps, commanded by General Heinz Guderian, Germany’s premier bewegungskrieg theorist. Aggressive and confident, he was a good choice for such a daring operation. Under his command were the 1st, 2nd, and 10th Panzer Divisions along with the attached Grossdeutschland Infantry Regiment, an elite Army unit that would later be expanded to divisional strength. Photographic evidence of the campaign shows the armored divisions were well equipped with PzKpfw. III and IV tanks, the best the Wehrmacht possessed at the time, though not available in great numbers. Each division also contained motorized infantry and artillery.

On the Allied side, French planners were convinced the main German thrust would come through the Netherlands and Belgium, believing a large army could not quickly move through the Ardennes. The Allies’ Plan D was created for this eventuality. This plan would send three French armies and the entire British Expeditionary Force northward into Belgium to meet the German attack along the Dyle River. The Royal Air Force and French Air Force would prioritize their effort in this sector, leaving the Ardennes and Sedan defended by second-rate French units and some Belgian cavalry. To the south, the Maginot Line would stop any attacks from Germany itself.

Though the Germans have since become known for their tanks, during the Battle of France they actually had fewer tanks than the Allies. Moreover, French tanks were more heavily armed and armored than their Wehrmacht counterparts. Several factors served to negate this advantage, however. French tactics dispersed most of their tanks among their divisions in an infantry support role. The Germans concentrated their panzers to strike decisive blows where needed and exploit breakthroughs. German tank crews were usually better trained, and their vehicles were all equipped with two-way radios, allowing them to communicate and coordinate during battle. Only a few French tanks had radios at all, reducing many of them to using signal flags and other methods, which distracted tank commanders from controlling their crews. The French were also quite deficient in antiaircraft guns; most of those they had were obsolete. In terms of aircraft the Germans were dominant in numbers and overall quality. The German Junkers Ju-87 Stuka could act in the role of artillery with its accurate dive-bombing capability.
