forward.
In the first great airborne assault in history, 4,000 paratroops of Kurt Student’s 7th Airborne Division descended from the early morning sky May 10, 1940, into “Fortress Holland” around The Hague, Rotterdam, and Utrecht. The sudden appearance of this force in the heart of the Dutch defensive system staggered every Allied commander. The Dutch had expected to defend this region for a couple of weeks, long enough for the French to join them and hold it indefinitely. Immediately after Student’s parachutists grabbed four airports near Rotterdam and The Hague, Theodor von Sponeck’s 22nd Infantry Air-Landing Division (12,000 men) started arriving by transport aircraft.
The Germans tried to seize The Hague and the government by a coup de main, but failed, taking many casualties. They were, however, able to capture key bridges in the Dordrecht-Moerdijk-Rotterdam area and hold them until the 9th Panzer Division broke through the frontier and rushed to the bridges on May 13, 1940, eliminating all possibility of resistance.
On the same day the Germans carried out the first major aerial atrocity of World War II: their aircraft rained bombs down on the undefended center of Rotterdam, killing about a thousand civilians and terrorizing the country. Two days later, the Dutch capitulated. Their army had scarcely been engaged.
Another dramatic scenario played out at the bridges over the Maas (or Meuse) River and the Albert Canal around Maastricht—fifteen miles inside the Dutch frontier. The bridges here were vital to the Germans to get their panzers across and into the open plains of Belgium beyond. Dutch guards were certain to blow the spans the moment they heard the Germans had passed the frontier. The Germans, accordingly, decided on a surprise strike.
In addition, a way had to be found to neutralize the Belgian fort Eben Emael about five miles south of Maastricht. It guarded the Albert Canal and the Maas just to the east. Eben Emael, constructed of reinforced concrete and housing casemated 75-millimeter and 120-millimeter guns, had been completed in 1935 and was regarded as virtually impregnable. There was only one undefended part of the fort: the flat roof. This was Eben Emael’s undoing.
Adolf Hitler personally selected paratroop Captain Walter Koch to lead the mission. His force included a platoon of army combat engineers, under Lieutenant Rudolf Witzig.
Early on May 10, 1940, twenty-one ten-man gliders drawn by Junker 52 transports pulled off from fields near Cologne. Over Aachen at 8,000 feet, the gliders unhooked and slowly descended over Dutch territory, ten landing beside four key bridges, and nine landing right on top of the Eben Emael roof. Lieutenant Witzig was not among them. His and another glider’s ropes snapped, and his glider had to be retrieved by another Ju-52. Before Witzig arrived, his sergeant, Helmut Wenzel, had taken charge and set explosive charges in gun barrels, casemates, and exit passages. In moments the German engineers had incapacitated the fort and sealed the 650- man garrison inside. The next day German infantry arrived, and the fort surrendered.
While this attack was going on, storming parties under Captain Koch seized four Albert Canal bridges before the astonished defenders could destroy them.
But special detachments of German spies failed to grab the Maas bridges at Maastricht, and the Dutch blew them. This held up part of Erich Hoepner’s 16th Corps panzers for forty-eight hours. Then they burst across, and opened a wide path for Walther von Reichenau’s following 6th Army.
The Allied commander, General Maurice Gustave Gamelin, ordered the main Allied force on the left wing, the 1st Group of Armies under Gaston Harve Billotte, to rush to the Dyle River. Included in this force were France’s three “light mechanized divisions” of converted cavalry with 200 tanks apiece. On the left of this army group was the British Expeditionary Force (BEF) of eight divisions under Lord Gort. The British moved to the line Louvain- Wavre south of the Belgian army, while the French swung in below the British from Wavre southward to Namur and Dinant on the Meuse. Meanwhile Gamelin directed French cavalry— motorized forces, armored cars, and horse brigades—to penetrate into the Ardennes and hold up the Germans.
Gamelin also ordered the French 7th Army under Henri Giraud to rush to Breda, about thirty miles southeast of Rotterdam, intending to link up with the Dutch. But with Fortress Holland breached, the 7th Army withdrew to Antwerp, Belgium.
To serve as a hinge around Sedan between the Maginot Line and the armies that had swept northeastward, Gamelin relied on two French armies (the 2nd and 9th) of four cavalry divisions and twelve infantry divisions, composed mostly of older reservists. This Sedan sector was the least fortified portion of the French frontier. Cavalry would be useless against tanks, and the infantry possessed few antitank or antiaircraft guns.
Meanwhile the Luftwaffe exerted all its efforts to beat down Allied air defenses and knock out enemy aircraft on the ground. The Germans were successful in large degree because the Dutch, Belgian, and French fighters were inferior to the Messerschmitt 109s, and the British Royal Air Force held back its Spitfires in England.
German bombers attacked railways, roads, and troop assembly areas. They created fear and chaos, and made the German ground advance much easier. Planes, mainly Stukas, stayed with the German advance troops, guarding flanks, knocking out defensive positions, and stopping enemy armored movements. After a week the Luftwaffe enjoyed superiority, and by another week it had achieved air supremacy.
Behind Hoepner’s panzers (3rd and 4th Divisions), the 6th Army advanced quickly, encircled the Belgian fortress of Liege, and pressed the Allies and Belgians back to Antwerp and the Dyle line. Georg Kuchler’s 18th Army, which had moved into Holland, turned on Antwerp as soon as the Dutch surrendered, and seized the city on May 18. The French cavalry that had advanced into the Ardennes made little impression on the German forward elements, and withdrew behind the main Allied positions.
The French First Army, with thirteen infantry divisions and 800 tanks, had been ordered to hold at all costs the “Gembloux gap,” the twenty-two-mile space between Wavre on the Dyle and Namur on the Meuse. Unfortunately, the commander distributed his armor all along the line.
On May 14–15, German panzers struck around the town of Gembloux. Here about 150 French tanks were concentrated, more than the Germans brought up in the beginning. The French drove the German panzers back in a fierce, rolling battle. But more German tanks kept coming up, and the French, now outnumbered, withdrew on May 15, opening the flood gates to the German panzers.
The Belgians and the Allies fell back to the Scheldt River, fifteen to thirty miles west. It was beginning to look like a rout. But the German high command didn’t want to hurry the Allies into too rapid a retreat before the net had stretched across their rear. Accordingly, it took 16th Corps away to back up the drive through the Ardennes, and also withdrew Luftwaffe support.
The German successes had stunned the world. At this moment a great voice lifted to rally the Allies, inspire democratic peoples everywhere, and defy Hitler. Winston Churchill stood before the House of Commons on May 13 and said: “I have nothing to offer but blood, toil, tears, and sweat. If you ask me, what our war aim is, I give you only one answer: Victory! Victory whatever the cost!”
While the world’s attention was riveted on the spectacular battles in Belgium and Holland, the actual
The leading element was the 19th Panzer Corps (1st, 2nd, and 10th Divisions), commanded by the father of German armored warfare, Heinz Guderian. His tanks were targeted at Sedan on the Meuse. Just to the north was Georg Hans Reinhardt’s 41st Panzer Corps with two divisions (6th and 8th), aimed at Montherme, about fifteen miles northwest of Sedan. Each of the five panzer divisions averaged 253 tanks.
About twenty-five miles north of Reinhardt was Hermann Hoth’s 15th Panzer Corps with two divisions, the 5th and 7th (under Erwin Rommel, soon to be famous), with a total of 542 tanks. This corps’s job was to get across the Meuse at Dinant and keep the Allies in Belgium from interfering with Guderian and Reinhardt in their thrust westward.
Everything depended on speed. The Germans had to cross the Meuse before the Allies woke up to the danger. If they did, they still had time to assemble a formidable defensive line along the river and delay the offensive long enough to bring up reinforcements. If that happened, the Allies might counterattack through Army
