June 6, 1944—D-Day—marks one of the most pivotal moments in modern history. In the early hours of the morning, Allied forces launched the largest amphibious invasion ever attempted, storming the beaches of Normandy, France. Over 156,000 troops from the United States, the United Kingdom, Canada, and other Allied nations began the push to liberate Europe from Nazi occupation. The planning was meticulous, the risks enormous, and the cost of human life staggering. But D-Day marked the beginning of the end for the Axis powers in Europe.

To reflect on this turning point in World War II, we share a remarkable episode from the 1952–1953 documentary series Victory at Sea. Produced by NBC in collaboration with the U.S. Navy, the series used archival footage, original scoring by Richard Rodgers, and narration to bring the naval war to life.

Episode 15, “D-Day,” captures the intensity, scale, and gravity of the Normandy invasion. Through original wartime footage, it offers a stirring glimpse into the courage and coordination that defined Operation Overlord. More than 80 years later, Victory at Sea remains a powerful lens through which to witness the enormity of that day.

Watch the episode below and take a moment to reflect on the sacrifices made in the name of freedom.
