Still, Wallace thinks he was lucky.

“I remember the good friends that I lost there. So it’s a little emotional,” he said, with sadness in his voice. “I guess you can say I’m proud of what I did but I didn’t do that much.”

 “Calvados!” he joked, in reference to Normandy’s local alcohol.

French and U.S. flags at half staff in Colleville-sur-Mer on Monday.

On D-Day, Allied troops landed on the beaches code-named Omaha, Utah, Juno, Sword and Gold, carried by 7,000 boats. On that single day, 4,414 Allied soldiers lost their lives, 2,501 of them Americans.

Wallace, who is using a wheelchair, was among about 20 WWII veterans who opened Saturday’s parade of military vehicles in Sainte-Mere-Eglise to great applause from thousands of people, in a joyful atmosphere. He did not hide his pleasure, happily waving to the crowd as parents explained the achievements of World War II heroes to their children.

Many history buffs, wearing military and civilian clothes from the period, also came to stage a reenactment of the events.

In Colleville-sur-Mer on Monday, U.S. Air Force aircraft are to fly over the American Cemetery during the commemoration ceremony, in the presence of Army Gen. Mark Milley, chairman of the Joint Chiefs of Staff. The place is home to the gravesites of 9,386 people who died fighting on D-Day and in the operations that followed.

For 82-year-old Dale Thompson, visiting the site over the weekend was a first.

Thompson, who traveled from Florida with his wife, served in the 101st Airborne Division of the U.S. military in the early 1960s. He was stateside and saw no combat.

Walking amid the thousands of marble headstones, Thompson wondered how he would have reacted if he landed at D-Day.

“I try to put myself in their place,” he said. “Could I be as heroic as these people?”
