Events

Belgian border guards reported the first German cavalry patrols crossing near the fortress city of Liège before dawn on August 4, 1914, and by nightfall Britain had entered a war that would kill millions. Germany's invasion of neutral Belgium, undertaken to execute the Schlieffen Plan's flanking march toward Paris, triggered the treaty obligation that drew the British Empire into what was supposed to be a continental European conflict. A "scrap of paper," as German Chancellor Bethmann-Hollweg dismissively called the 1839 Treaty of London guaranteeing Belgian neutrality, had just expanded the war to global proportions. Belgium's small but determined army refused to stand aside. The fortifications at Liège held for twelve days against an attacking force many times their size, buying crucial time for French and British forces to deploy. German frustration at Belgian resistance led to a series of atrocities against civilians — the burning of the university library at Leuven, mass executions at Dinant and elsewhere — that were documented by international observers and became a powerful propaganda tool for the Allied cause. Britain's entry transformed the strategic calculus entirely. The Royal Navy imposed a blockade that would slowly strangle Germany's economy and food supply. The British Expeditionary Force, though small by continental standards, arrived in France in time to fight at Mons and help slow the German advance. Most critically, Britain's entry brought the resources of the world's largest empire into the war, including troops from India, Canada, Australia, New Zealand, and South Africa. The United States declared neutrality that same day, a position it would maintain for nearly three years. But the violation of Belgian neutrality shaped American public opinion from the start, creating a moral framework that would eventually help justify U.S. entry in 1917. One invasion on one August morning turned a European crisis into the first truly global war.

German police climbed the stairs to a hidden annex behind a bookcase in an Amsterdam warehouse on the morning of August 4, 1944, and arrested the eight people who had been living in secret for over two years. Among them was a fifteen-year-old girl named Anne Frank, whose diary would become the most widely read personal account of the Holocaust. SS-Oberscharführer Karl Silberbauer led the raid after receiving a tip from an informer whose identity has never been conclusively established despite decades of investigation. The Frank family — Otto, Edith, and daughters Margot and Anne — had gone into hiding on July 6, 1942, along with the van Pels family and Fritz Pfeffer. They survived in the cramped space above Otto Frank's pectin and spice business, supplied by a small group of trusted Dutch employees including Miep Gies and Bep Voskuijl. Anne documented their confinement, her fears, her adolescent emotions, and her observations about human nature in a diary she called "Kitty." After arrest, the eight were sent to Westerbork transit camp and then deported to Auschwitz on the last transport to leave the Netherlands. The men and women were separated on the platform. Anne and Margot were later transferred to Bergen-Belsen, where both died of typhus in February or March 1945, just weeks before the camp was liberated by British forces. Of the eight people hidden in the annex, only Otto Frank survived the war. Miep Gies had gathered Anne's scattered papers from the annex floor after the arrest, intending to return them. She gave the diary to Otto Frank after confirming that Anne had not survived. Published in 1947 as "Het Achterhuis" and eventually translated into more than 70 languages, the diary gave a human face to six million murders, ensuring that one teenager's voice would outlast the regime that tried to silence her.
