German invasion of the Low Countries. The German invasion of the Low Countries, codenamed Fall Gelb (Case Yellow), commenced on 10 May 1940 and marked the beginning of the decisive Battle of France. This strategic offensive by Nazi Germany targeted the neutral nations of the Netherlands, Belgium, and Luxembourg, aiming to outflank the formidable Maginot Line and draw Allied forces north. The rapid success of the Wehrmacht, employing combined arms Blitzkrieg tactics, led to the swift capitulation of the Netherlands and Belgium, precipitating the Dunkirk evacuation and the eventual fall of France.

Background and planning

Following the conclusion of the Phoney War, German high command, under Adolf Hitler, sought a decisive victory in the west to secure its rear before a potential conflict with the Soviet Union. The initial plan, a reiteration of the Schlieffen Plan, was radically altered by proposals from Erich von Manstein, which emphasized a surprise thrust through the Ardennes forest. The invasion of the Low Countries was designed as a strategic feint to lure the best Allied mobile units, including the British Expeditionary Force and the French First Army, into Belgium. This maneuver would create a gap for German Panzer divisions to exploit further south, aiming to sever Allied communications. The plan relied on overwhelming air superiority from the Luftwaffe and audacious use of airborne forces, as seen in the preceding Norwegian campaign.

Invasion and initial operations

At dawn on 10 May 1940, German forces launched simultaneous assaults across multiple frontiers. Army Group B, commanded by Fedor von Bock, invaded the Netherlands and northern Belgium, while Army Group A, under Gerd von Rundstedt, advanced through Luxembourg and the densely wooded Ardennes. Key initial operations included the capture of the vital Fort Eben-Emael by German Fallschirmjäger using gliders and shaped charges, and the seizure of bridges over the Albert Canal. The Luftwaffe, including Junkers Ju 87 Stuka dive bombers, launched devastating attacks on Allied airfields and communication hubs, establishing air dominance. The rapid collapse of Luxembourg occurred within hours, while Dutch and Belgian forces mobilized to their defensive lines.

Battle for the Netherlands

The Dutch defense, coordinated by General Henri Winkelman, centered on the Water Line and the defense of Rotterdam. German airborne troops, including those from the 7th Flieger Division, attempted to capture The Hague and key bridges at Rotterdam and Dordrecht. Despite fierce resistance, the German breakthrough at the Grebbeberg and the terror bombing of Rotterdam by the Luftwaffe's Kampfgeschwader 54 compelled the Dutch government to capitulate on 15 May. The Battle of the Afsluitdijk represented a rare Dutch defensive success, but the overall campaign lasted only five days, with Queen Wilhelmina evacuating to the United Kingdom.

Battle for Belgium

Belgian forces, under King Leopold III, fell back from their forward positions along the Albert Canal to the primary defensive line anchored on the Dyle River, as per the Allied Dyle Plan. Major engagements included the delaying action at the Battle of Hannut, the largest tank battle of the campaign to that date, fought between French SOMUA S35 and German Panzer III units. Despite stubborn resistance at positions like the Fort Eben-Emael, the Belgian line was progressively outflanked and overwhelmed by the advancing Wehrmacht. The Belgian Army's surrender on 28 May, following the collapse of the Lys position, created a critical crisis for the encircled Allied forces to the south.

Allied response and the Dunkirk evacuation

In response to the invasion, the Allies executed the pre-arranged Dyle Plan, moving forces into Belgium to form a continuous front. However, the devastating German breakthrough at the Battle of Sedan, achieved by Panzer Group Kleist, threatened their southern flank. As the strategic situation deteriorated, the British Expeditionary Force under Lord Gort and remnants of the French First Army were pushed back towards the English Channel. The subsequent Battle of Dunkirk and the miraculous Dunkirk evacuation (Operation Dynamo), overseen by Admiral Bertram Ramsay, saved over 330,000 Allied soldiers between 26 May and 4 June, though they abandoned nearly all their heavy equipment.

Aftermath and consequences

The swift German victory in the Low Countries had catastrophic consequences. It exposed northern France to invasion, leading directly to the Battle of France and the French armistice in June 1940. The Netherlands and Belgium remained under German occupation, administered by the Reichskommissariat Niederlande and Military Administration in Belgium and Northern France, respectively, until their liberation in 1944-1945. The campaign demonstrated the decisive effectiveness of Blitzkrieg and combined arms warfare, fundamentally altering modern military doctrine. Politically, it led to the resignation of British Prime Minister Neville Chamberlain and the rise of Winston Churchill, while solidifying Hitler's dominance in continental Europe and setting the stage for the Battle of Britain.
