Before the sun had crested the horizon on May 10th, 1940, the world above the Low Countries erupted in violence. German bombers, their undersides glinting silver in the dawn, swept over the flat Dutch and Belgian countryside. The sky above Rotterdam and Brussels became a latticework of white contrails, streaking east to west, as hundreds of aircraft thundered overhead. The droning engines drowned out the wail of air raid sirens, which mingled with the distant thump of falling bombs. In the streets, civilians abandoned bicycles and handcarts, clutching children and whatever possessions they could carry. The air was thick with fear and the acrid stench of smoke as the Luftwaffe targeted airfields, rail yards, and bridges, sowing chaos and confusion before the first German tanks even reached the frontiers.
In Rotterdam, the ground shook as bombs fell, sending plumes of black smoke twisting into the morning light. Shattered glass rained down on cobblestones; the blast of an explosion flung a woman against a wall, her bundle of blankets torn from her arms. Amid the confusion, the city’s firefighters struggled in vain against fires that leapt from one wooden rooftop to the next. Burnt paper drifted through the air, catching on telephone wires and settling on the shoulders of stunned survivors. Some crouched in cellars, faces streaked with tears and soot, as the world above them seemed to collapse.
Farther east, the German airborne made their move. Paratroopers—Fallschirmjäger—descended on the Dutch fortress of Eben-Emael, their parachutes blooming white against the pale sky. The air was alive with the crackle of gunfire and the concussive roar of explosions as the attackers landed atop the concrete fort. The defenders, caught off guard, watched in disbelief as teams of Germans set hollow charges against steel turrets. The blasts sent chunks of reinforced concrete spinning into the air, showering the ground with dust and rubble. By nightfall, the once-mighty fortress, considered one of Europe’s strongest, lay silent—its surviving defenders dazed and ringed by armed Germans.
On the ground, the German Wehrmacht surged forward in three massive army groups. To the north, Army Group B pushed into Belgium and the Netherlands, drawing the bulk of French and British forces northward. The Allies, convinced this was the main thrust, rushed to meet the invaders. British Tommies and French poilus, faces set in grim determination, clambered aboard trains and trucks, their rifles clutched tightly. The roads quickly became clogged with a chaotic mix of military convoys and civilian traffic. Columns of refugees shuffled alongside columns of tanks. Children stumbled beside carts loaded with bedding and furniture, while old men, exhausted, collapsed by the roadside. Refugees wept openly as distant artillery rumbled, their faces etched with terror and disbelief. The air along these roads was thick with dust and the pungent odor of burning oil and petrol, as retreating units torched fuel dumps to deny them to the enemy.
Yet, as the mass of the Allied armies moved north, the real hammer blow fell elsewhere. In the south, the dense, mist-shrouded forests of the Ardennes concealed a German gamble. Army Group A, led by Heinz Guderian’s Panzer divisions, threaded through narrow, muddy forest roads. The rain-soaked earth turned to sucking mud beneath the tank tracks, spattering uniforms and clogging boots. French patrols, peering through the early morning fog, caught fleeting glimpses of armored columns, but their urgent reports were dismissed as exaggerations by headquarters. The French Seventh Army, stretched thin and unprepared for an armored onslaught, was caught off guard when the first panzers burst from the woods. Within hours, bridges over the Meuse fell into German hands, the defenders pushed back by the relentless advance.
In the confusion, communication faltered. Field telephones crackled with static as desperate calls for reinforcements went unanswered. French units, isolated and unsure of orders, lost contact with headquarters. At Sedan, German engineers labored under a hail of machine-gun fire to construct pontoon bridges across the Meuse. The river’s surface rippled with the impact of bullets and shrapnel, while Stuka dive-bombers screamed down from the gray sky, their sirens wailing, their bombs churning the riverbanks into a morass of mud and blood. French infantry, pinned in shallow trenches, watched in horror as the enemy crossed in force. By the end of May 13th, the Germans had established a bridgehead—a feat that shattered Allied confidence.
The human cost mounted with every passing hour. In Rotterdam, a concentrated German bombing raid obliterated the city center. Firestorms raged unchecked, consuming entire blocks; the heat was so intense that iron lampposts twisted and collapsed. Thousands perished beneath the rubble, their bodies pulled from smoking ruins by rescue workers with hollow eyes. The city’s ancient churches and merchants’ houses, centuries old, were reduced to blackened shells. The Dutch, faced with annihilation, surrendered the following day.
Belgium fared little better. In towns like Dinant and Louvain, battle raged through medieval streets. Stone facades crumbled under shellfire; stained glass windows shattered, scattering colored fragments across pews already spattered with blood. The dead lay where they had fallen—soldiers and civilians alike—while survivors picked their way through the wreckage in search of family. The sense of safety that had lingered from the last war vanished in the roar of artillery and the relentless grind of tank treads.
Allied morale began to disintegrate. Rumors swept through the ranks of German spies and fifth columnists sabotaging defenses. Fear and suspicion led to panic; in some cases, angry crowds turned on suspected traitors, and lynchings took place in the chaos. Along the roads, the endless tide of refugees became a living barrier, choking military movements. Some French officers, desperate to stem the German advance, ordered bridges demolished even as columns of refugees still struggled across, the blasts sending men, women, and children tumbling into rivers already swollen with spring rain.
By May 15th, the Battle of France had become a rolling disaster. The German spearhead had burst through the heart of the Allied lines. Hopes of a quick victory evaporated. Soldiers and civilians alike now faced a new terror—the prospect of encirclement. The trap was closing fast, and the world watched as France teetered on the brink.
