Today marks the 78th anniversary of the D-Day landings.
Here’s what happened on the fateful day – and why it was so crucial.
What were the D-Day landings?
D-Day, codenamed Operation Overlord, was the greatest combined land, air and naval operation in history.
Around 4,400 Allied troops paid the ultimate price for ensuring D-Day was one of the most successful military operations the world has ever seen.
With the simple words “OK, let’s go”, General Dwight Eisenhower set in motion the greatest military attack in history.
On 6 June 1944, some 156,000 British, American and Canadian troops arrived on French soil from sea and air in an effort to free Europe from the Nazis.
Many thousands more served on board the 6,000 troop ships, landing crafts and barges off the Normandy coast in northern France.
The then Prime Minister Winston Churchill described the operation as “undoubtedly the most complicated and difficult that has ever taken place”.
Thousands of paratroopers were dropped behind the enemy lines to capture bridges – including the vital Pegasus Bridge – railway lines and roads to prevent the German army sending reinforcements once the Allies landed.
Between the hours of 3am and 5am on June 6, more than 1,000 British aircraft dropped some 5,000 tons of bombs.
Tip-offs from French Resistance fighters, who also carried out over 1,000 sabotage attacks, helped the Allies target their bombing campaign to cause maximum disruption for the Germans.
A main target was the Atlantic Wall, a network of concrete gun emplacements, machine gun nests, tank traps and mines, barbed wire and booby traps that the Germans had built up since 1940 along France’s west coast.
What were the beaches called?
Each of the landing beaches was given a codename on the Allies’ secret map. The British and Canadians landed on Gold, Juno and Sword beaches to the east, while the Americans went ashore at Utah and Omaha beaches in the west.
Why was D-Day so important?
D-Day established another front in Europe, locking Germany into conflict in France, Italy and Russia. It helped overwhelm Hitler’s Nazi Reich and led eventually to the Allies’ victory in Europe in May 1945.
What does D-Day stand for?
The words “doom”, “debarkation” and “deliverance” have all been suggested as meanings for the “D” in D-Day.
But the letter is derived from the word “Day” and means the day on which a military operation begins.
D-Day has been used for many different operations but is most closely associated with the Allied landings on Normandy’s beaches on 6 June 1944.
The day before D-Day was D-1 and the day after was D+1.
It meant that if the date for an operation changed, military staff would not have to alter all the dates in their plan.
This happened during the Normandy D-Day landing operation, which was originally planned for 5 June – but bad weather delayed it by a day.
In the build-up to the Allied invasion, code names and acronyms were vital to help maintain the blanket of secrecy around the operation.
