The numbers are staggering: 160,000 Allied troops. Five thousand ships and 13,000 aircraft. All to take a heavily fortified 50-mile stretch of French shoreline, a herculean effort to reclaim a critical part of Europe from the Nazis and turn the tide of the most horrific war the world had ever seen.
On June 6, 1944 − D-Day − World War II's invasion of Normandy, codenamed Operation Overlord, got underway. Gen. Dwight D. Eisenhower, supreme commander of the Allied Expeditionary Force, told the men as they mobilized for battle: "The eyes of the world are upon you. ... The hopes and prayers of liberty-loving people everywhere march with you."
Tolley Fletcher, at the time a 19-year-old Navy gunner's mate, remembered the rough seas and the treacherous landing troops at Utah Beach had to make in 3- to 4-foot waves, each carrying about 60 pounds of gear on their backs and descending on rope ladders from larger ships onto smaller landing crafts.
"I felt for those soldiers," Fletcher, now 100 years old, told USA TODAY. "In my mind, that was the worst part, other than people getting hurt."
Fletcher, who joined the Navy at 17 in late December 1941, said he and his shipmates were fortunate to be mostly out of the line of fire. "There was some shelling, not really a lot, and luckily we didn't get hit.
"Maybe halfway in, we started seeing lots of bodies in the water," said Fletcher, who now lives in the Baton Rouge, Louisiana, area. "I was asked (later) what we did about it. We didn't do anything about it − we had a job: to escort those troops to the beach."
On D-Day, "that's what these guys faced," said Peter Donovan Crean Sr., vice president for education and access at the National World War II Museum in New Orleans. "They knew they were in the presence of history. Soldiers, sailors, Marines − they knew what they were doing was going to go down in history, which also meant they knew the danger involved.
"Guys who were 18, 19, 20 years old were faced with the possibility of their death, but they did it anyway."
As we mark the 81st anniversary of D-Day, here is a look at what happened on the beaches of Normandy, the men who fought knowing they might not survive to see victory and the way it affected the Allies' fight to defeat fascism, genocide and tyranny.
What happened on D-Day?
In order to defeat the Nazis in Europe, the Allies knew they'd have to take France, under German occupation since 1940. Operation Overlord saw a mobilization of 2,876,000 Allied troops in Southern England, as well as hundreds of ships and airplanes, in preparation for a ground invasion, the largest the world had seen.
Weighing conditions including the weather, disagreements among other military leaders and strategic uncertainty, Eisenhower gave the go-ahead for the operation to begin before dawn on June 5, 1944. If things didn't go well for the Allies, Eisenhower wrote a note accepting responsibility. The following day, nearly 160,000 Allied troops landed along the 50-mile stretch of French shoreline.
More than 9,000 Allied troops were killed or wounded, and 100,000 troops would continue the slow, bloody journey to Berlin, the center of German power.
Why was it called D-Day?
According to the U.S. Army, D-Day was "simply an alliteration, as in H-Hour." Some believe the first "D" also stands for "day," a code designation, while the French say the "D" stands for "disembarkation." The Army's website says that "the more poetic insist D-Day is short for 'day of decision.'"
Asked in 1964, Eisenhower instructed his assistant Brig. Gen. Robert Schultz, to answer. Schultz wrote that "any amphibious operation has a 'departed date'; therefore the shortened term 'D-Day' is used.”
What happened after D-Day?
D-Day was not the only decisive battle of the European theater, Crean said.
"It was a crucial battle but there were more ahead," he said. "They had 700 miles of tough road ahead to get to Berlin."
The Battle of the Bulge, waged over 41 days in December 1944 and January 1945, required 700,000 Allied troops. "It was a tough slog for another 11 months," Crean said.
Victory in Europe − V-E Day − would come on May 8, 1945, nearly a year after D-Day. The war wouldn't end until the Japanese surrendered on Sept. 2, 1945.
How many World War II veterans remain in the U.S.?
There are about 66,000 surviving World War II veterans in the United States, Crean said, and while that may sound like a lot, it's a tiny fraction of the 16.4 million who served their country in the conflict.
"So to be able to talk to and thank one veteran now is a gift for any of us," Crean said.
The National World War II Museum's mission "is more critical than ever ... so more people will understand what they did and continue to be inspired by their sacrifices," added Crean, a retired colonel with 30 years' service in the Army.
The museum has had oral historians travel the country to record more than 12,000 personal stories from World War II veterans. They've conducted extensive interviews with veterans, Holocaust survivors and homefront workers and, using artificial intelligence, created a way for visitors to have "conversations" with them and ask questions to learn about the war effort. And they offer virtual programming, teacher training and a student leadership award.
Fletcher, the Navy gunner's mate, said he's uncomfortable with the idea of being considered a hero. Asked about his role in history, he said, "I really didn't think about it then, and I don't think about it now, though it's been impressed upon me quite a bit.
"When I think about what I went through, and what all the Army and the other men who were mixed up in really tough situations, it makes me feel a little bit guilty."
