Winston Churchill Becomes British Prime Minister

As German forces launched their invasion of Western Europe in May 1940, British Prime Minister Neville Chamberlain faced a loss of confidence in Parliament. On May 10, King George VI appointed Winston Churchill, then First Lord of the Admiralty, to form a new national coalition government. Churchill had long warned about the Nazi threat and advocated a more aggressive stance against Germany. His appointment came on the same day German troops crossed into the Netherlands, Belgium, and Luxembourg. Churchill immediately addressed the nation, promising only “blood, toil, tears and sweat” in the fight ahead.

Dunkirk Evacuation Operation Dynamo Begins

German armored columns had driven Allied forces into a pocket around the French port of Dunkirk on the English Channel. On May 26, 1940, the British Admiralty launched Operation Dynamo to evacuate trapped British, French, and other Allied troops. Initial naval efforts were supplemented by hundreds of civilian vessels that crossed the Channel under Luftwaffe attack. Over the following days the improvised armada ferried more than 338,000 soldiers to safety in Britain despite the loss of equipment and ships.

German Forces Enter and Occupy Paris

Following the rapid German advance through the Low Countries and northern France in the Battle of France, French defenses collapsed. On June 14, 1940, German troops entered Paris, which had been declared an open city to spare it destruction. Parisians awoke to loudspeakers announcing a curfew as Wehrmacht units marched in and raised swastikas over landmarks including the Eiffel Tower. The occupation marked the effective end of the Battle of France and led directly to the armistice signed days later.

France Signs Armistice with Nazi Germany

After the rapid German Blitzkrieg overran much of France in May and June 1940, the French government under Marshal Philippe Pétain sought terms to avoid total destruction. Negotiations occurred in the same railway car at Compiègne where Germany had surrendered in 1918. On June 22 the armistice was signed, dividing France into an occupied northern zone and an unoccupied southern zone governed from Vichy. Pétain's regime retained nominal sovereignty but collaborated with Germany. Fighting ceased at midnight on June 25.

Battle of Britain Air Campaign Begins

Following the fall of France in June 1940, Nazi Germany prepared for a potential invasion of Britain known as Operation Sea Lion, which required control of the skies over the English Channel. On July 10, 1940, the Luftwaffe launched its first major attacks, targeting British shipping convoys in the Channel and ports in southern England and Wales. Royal Air Force fighters responded, beginning a sustained air battle that lasted into October. The campaign involved thousands of aircraft on both sides, with Britain relying on radar, integrated defense systems, and skilled pilots including many from Commonwealth nations. German losses mounted while British production and resolve held firm.

Largest Air Battle of Battle of Britain Fought

In the summer of 1940, Nazi Germany launched an air campaign to gain superiority over the Royal Air Force ahead of a planned invasion of Britain. The Luftwaffe intensified attacks on August 18, targeting RAF airfields, radar stations, and aircraft factories in what became known as the Hardest Day. Over 1,000 German aircraft crossed the English Channel in multiple waves, met by determined British fighters. Intense dogfights raged across southern England, with both sides suffering heavy losses—approximately 69 German and 68 British aircraft destroyed. The RAF successfully defended its bases and maintained operational capacity despite the scale of the assault.

German Luftwaffe Launches the Blitz on London

Following the Battle of Britain, Nazi Germany shifted strategy to terror bombing of British cities to force surrender. On September 7, 1940, approximately 300 German bombers, escorted by fighters, conducted a massive daylight raid on London docks and East End neighborhoods. The attack killed hundreds of civilians and marked the start of 57 consecutive nights of bombing known as the Blitz. British defenses, including radar and night fighters, responded but could not prevent widespread destruction in the initial phase. The campaign aimed to break civilian morale and disrupt industry but ultimately hardened British resolve under Prime Minister Winston Churchill.

Lascaux Cave Paintings Discovered in France

During the early years of World War II in occupied France, four teenagers exploring the countryside near Montignac stumbled upon a hidden entrance. On September 12, 1940, while investigating a hole created by an uprooted tree, they descended into a network of caves adorned with vivid prehistoric paintings estimated at 15,000 to 17,000 years old. The artwork featured detailed depictions of animals such as bulls, horses, and deer, executed with remarkable sophistication using natural pigments. Local authorities and archaeologists quickly confirmed the significance of the Upper Paleolithic site, often called the 'Sistine Chapel of prehistoric art.' The discovery provided unprecedented insight into early human artistic expression and symbolic thinking.

Italy Launches Invasion of Egypt in WWII

Following Italy's entry into World War II, Benito Mussolini ordered Marshal Rodolfo Graziani to advance from Libya into British-controlled Egypt to threaten the Suez Canal. On September 13, Italian forces crossed the border in Operation E, initially capturing Sollum and advancing toward Sidi Barrani despite logistical challenges. British Commonwealth troops conducted delaying actions but withdrew to prepared positions at Mersa Matruh. The limited Italian advance exposed supply weaknesses in the desert theater. It marked the opening of the Western Desert Campaign.
