Today marks the 75th anniversary of the Allied invasion of Normandy during World War II.
Troops from the U.S., Great Britain, Canada and France attacked German forces on the coast of northern France. Code-named "Operation Neptune" and known as D-Day, the landings kicked off a drive to liberate Europe.
It began with air bombardment shortly after midnight June 6, 1944. A massive campaign followed, with more than 24,000 Allied assault troops and 1,200 aircraft, according to the White House.gov website. Out of 160,000 Allied troops at Normandy, 73,000 were American. As many as 4,400 troops died that day from the combined Allied forces, and some 9,000 were wounded or missing, the BBC reports. While the number of German casualties that day are unknown, an estimated 4,000 to 9,000 died.
