June 6, 2019, marks 75 years since D-Day, when Allied troops stormed the beaches of Normandy during World War II.
On June 6, 1944, roughly 160,000 troops landed in Normandy, France, on five beaches with the code names Utah, Omaha, Gold, Juno, and Sword.
D-Day involved astonishing coordination between Allied forces. Over 13,000 paratroopers were dropped behind enemy lines before daybreak. At approximately 6:30 am, the first wave of assault troops hit the beach.
It was one of the most important moments in the war and represented the largest amphibious invasion in world history. D-Day marked a turning point in the fight against Nazi Germany, which would surrender less than a year later in May 1945.
But it was by no means an easy victory, and cost many lives along the way: roughly 22,000 Allied troops were killed or wounded on June 6 alone.
On that day, and in the seven and half decades since, world leaders have delivered legendary speeches about D-Day — including on the blood-stained beaches where it occurred.
Here are five of the most powerful speeches on D-Day.
