Vintage photos honor the resting place of D-Day's fallen heroes

In 1957, 'National Geographic' covered the dedication of American World War II cemeteries abroad, including the Normandy American Cemetery in France where more than 9,000 U.S. troops are buried.

National Geographic covered the creation of World War II memorials and cemeteries for fallen U.S. soldiers in foreign lands in a 1957 article "Here Rest in Honored Glory." These somber, sacred spaces, including the Normandy American Cemetery in France, paid tribute to those who made the ultimate sacrifice for their country. Many of the heroes of D-Day are buried here, including two children of President Theodore Roosevelt, his sons Theodore Jr. and Quentin rest among more than 9,000 other graves.

The Normandy American Cemetery and Memorial is located in Colleville-sur-Mer, France. It stands on the site of the temporary American St. Laurent Cemetery, established by the U.S. First Army on June 8, 1944, as the first American cemetery in Europe during World War II. Of the dedication ceremony in 1956, National Geographic photographer and author Howell Walker wrote: "Hundreds of French and Americans attended the consecration of this battle monument in Normandy. Statesmen, and military men of both nations voiced their people's gratitude to those who died for the cause of liberty."

Then President Dwight D. Eisenhower simply wrote: "They will never be forgotten."
