A combined British and French fleet of 16 battleships launched a massive naval assault to force the Dardanelles strait and threaten Constantinople. Concealed Ottoman minefields proved devastating, the French battleship Bouvet capsized and sank in two minutes, killing 639 of her 710 crew. HMS Irresistible and HMS Ocean also sank, and HMS Inflexible was badly damaged. Three capital ships lost in a single afternoon. The failure led directly to the catastrophic Gallipoli Campaign that cost over 250,000 Allied casualties.
Holy Roman Emperor Frederick II crowned himself King of Jerusalem in the Church of the Holy Sepulchre, having achieved through diplomacy what five previous Crusades had failed to win through force. His treaty with the Sultan of Egypt restored Jerusalem, Bethlehem, and Nazareth to Christian control for ten years without a battle, the most remarkable diplomatic achievement of the Crusades.
Parliament voted 276-168 to repeal the Stamp Act of 1765, which had imposed direct taxation on the American colonies and provoked violent protests by the Sons of Liberty. However, on the same day, Parliament passed the Declaratory Act, asserting its authority to legislate for the colonies "in all cases whatsoever", setting the stage for further confrontations that led to the American Revolution.
After France's defeat in the Franco-Prussian War, the government ordered troops to seize cannons from the Paris National Guard at Montmartre. The soldiers refused to fire and fraternized with the crowd. Two army generals were captured and executed by the mob. The government fled to Versailles, and the National Guard seized control, establishing the Paris Commune, the first workers' government in modern history. It held power for 72 days before being crushed during "Bloody Week," with an estimated 10,000-20,000 Communards killed.
In response to France's plea for relief from the German assault on Verdun, Russia launched the Lake Naroch Offensive in present-day Belarus. Approximately 350,000 Russian troops attacked 75,000 Germans after the heaviest artillery bombardment yet seen on the Eastern Front, but the advance collapsed in muddy terrain with inaccurate fire. Russia suffered approximately 100,000 casualties versus 20,000 German losses, one of the costliest Russian failures of the war.
Adolf Hitler and Benito Mussolini held a summit in a railway carriage at the Brenner Pass on the Austro-Italian border. Hitler spoke for two hours, laying out his planned invasion of France while concealing his imminent attacks on Denmark and Norway. He pressured Mussolini to enter the war. Mussolini promised to join once German victory appeared certain, a commitment he fulfilled on June 10, 1940, expanding the war into North Africa and the Mediterranean.
Mount Vesuvius erupted violently while Allied forces were based around Naples, destroying 88 B-25 Mitchell medium bombers of the U.S. Army Air Forces' 340th Bombardment Group at the Pompeii Airfield. The eruption, the only one during the 20th century, was the only time a natural disaster destroyed an entire combat air unit during World War II.
France and the Provisional Government of the Algerian Republic signed the Evian Accords, ending the brutal seven-year Algerian War of Independence. A ceasefire took effect the following day. The war had cost an estimated 300,000-1,500,000 Algerian lives, profoundly destabilized French politics, including multiple assassination attempts on President de Gaulle, and triggered the collapse of the Fourth Republic.
Anti-government protests erupted in Daraa, Syria, after security forces arrested and tortured teenagers for writing anti-government graffiti. The government's violent crackdown on the protests triggered a nationwide uprising that devolved into a multi-sided civil war involving regional powers, jihadist groups, and eventually Russian and American military forces.

Lieutenant, Manchester Regiment, British Army
The most celebrated war poet of World War I, whose works, "Dulce et Decorum Est," "Anthem for Doomed Youth," and "Strange Meeting", exposed the horrifying reality of trench warfare and challenged the romanticized view of military glory. Awarded the Military Cross for courage at the Battle of Joncourt, Owen was killed in action at the Sambre-Oise Canal on November 4, 1918, one week before the Armistice.
German inventor of the diesel engine that revolutionized naval and military technology. The diesel engine became the standard power plant for submarines worldwide, fundamentally changing naval warfare in both World Wars. Diesel vanished from a steamship on September 29, 1913, while traveling to meet the British Royal Navy about powering submarines, a disappearance some attributed to German agents.
Marshal of the Soviet Union
The legendary commander of the 62nd Army at the Battle of Stalingrad, the bloodiest battle in human history. Chuikov developed the tactic of "hugging the enemy," keeping Soviet lines so close that the Luftwaffe could not bomb without hitting their own troops. He later led his forces from Stalingrad to Berlin, where he personally accepted the unconditional German surrender on May 2, 1945. He was buried at Mamayev Kurgan, the Stalingrad battlefield memorial.
