Episode 18 of Turning Points: History’s Greatest Battles examines the Battle of the Somme (1916), one of the deadliest and most defining battles of World War I. Launched by Britain and France to relieve pressure on Verdun and break the stalemate on the Western Front, the offensive relied heavily on an unprecedented artillery bombardment intended to destroy German defenses. However, the German army survived in deep bunkers, leaving their machine guns largely intact. On July 1, 1916, tens of thousands of British soldiers advanced across open ground, only to be cut down by devastating fire. The first day alone produced nearly 60,000 British casualties, making it the bloodiest day in British military history. Despite this catastrophe, the fighting continued for months, with gains measured in yards at enormous human cost. The Somme saw the first battlefield use of tanks, signaling the future of warfare, but they were too few and unreliable to change the battle’s outcome. By the time the offensive ended in November, more than one million men had been killed, wounded, or captured. Though it failed to deliver a decisive victory, the Battle of the Somme reshaped military thinking and public perception of war. It exposed the brutal realities of industrialized conflict and became a lasting symbol of sacrifice, loss, and the human cost of modern warfare.
