Monday marks the 78th anniversary of the historic D-Day operation.
In the midst of World War II, on June 6, 1944, Allied forces stormed the beaches of Normandy in Nazi-occupied France. More than 156,000 troops, including from the United States, Britain and Canada, fought Nazi forces on D-Day, reshaping warfare forever, according to the Department of Defense.
D-Day began the assault phase (called Operation Neptune) of the larger Allied invasion of northwest Europe led by General Dwight D. Eisenhower, known as Operation Overlord. According to Britannica, by the end of August 1944, all of northern France was liberated from Nazi control.

The exact number of those killed in the fighting is unknown, but research by the US National D-Day Memorial Foundation estimates that there were over 4,000 Allied dead and between 4,000 and 9,000 German casualties on D-Day.
Over 100,000 Allied and German soldiers died during the entire Battle of Normandy and around 20,000 French civilians are believed to have been killed in the bombardment.
Here are some D-Day photos taken all those years ago.
