• In the summer of 1914, a single assassination in Sarajevo quickly escalated into a continent-wide war, driven by rigid alliances and unstoppable army mobilizations.
• The Western Front froze into a 400-mile line of trenches stretching from the North Sea to Switzerland, creating a cratered wasteland known as no man's land.
• The conflict rapidly developed into industrial slaughter, employing machine guns, poison gas, artillery, and the first tanks and aircraft.
• Battles such as Verdun and the Somme in 1916 saw commanders send men against machine guns for months, leading to catastrophic losses.
• On the first day of the Somme alone, Britain incurred nearly 60,000 casualties for only a few hundred yards of territorial gain.
• World War I was a global conflict, with fighting ranging from Gallipoli and the Middle East to Africa and submarine warfare in the Atlantic.
• The year 1917 marked a critical shift as revolution pulled Russia out of the war, while America's entry poured fresh troops and vast industry into the Allied cause.
• By the autumn of 1918, Germany was broken, and the guns finally fell silent on the eleventh hour of the eleventh day of the eleventh month.
• The war's staggering human cost amounted to some 20 million dead, scarring an entire generation.
• The Treaty of Versailles redrew the map and crushed Germany with blame and debt, ultimately sowing the seeds for the next war just 20 years later.
