Final Thought: Monday marks the 78th anniversary of D-Day

Monday marked the 78th anniversary of D-Day, a moment that changed the course of history.

On June 6, 1944, nearly 160,000 Allied troops landed on the beaches of Normandy, France.

This marked the start of a lengthy and costly campaign to liberate Europe from Nazi occupation.

More than 4,400 Allied soldiers lost their lives on D-Day, including 2,500 Americans.
