The Normandy Landings (otherwise known as the D Day Landings) happened on the 6th of June 1944. It was the largest seaborne invasion in history involving nearly 5000 landing and assault craft, 289 escort vessels and 277 minesweepers. It was the start of the Allied victory over the Nazis.
Throughout WWII, Germany and its allies encrypted messages using Enigma machines. The Germans considered the Enigma code to be unbreakable, but the codebreakers at Bletchley Park in Buckinghamshire, the British forces' intelligence centre, managed to decipher the code. This enabled the British to plan operations to defeat the Germans. (Photo by SSPL/Getty Images)
The code breakers were helped by the first ever computer to crack the Enigma code. The computer was called Colossus and was built by Alan Turing. This image shows the circuitry and pulley-wheel system of the Colossus computer. (Photo by SSPL/Getty Images)
One of the operations that was planned by the Allied Troops was the D-Day landings in Normandy France. The plan was to land at various places on the coast of France and break down the German defences. This involved a lot of organisation and practise as troops would have to leave from all over England to land in France at the same time. This photo shows troops coming ashore during training exercises practising for the real thing. (Photo by Keystone/Getty Images)
Some US troops destined for the D Day landings were stationed in Falmouth leading up to the attack. Like elsewhere in England they also trained and prepared for the the invasion. This photo shows a US Army convoy passing the Red Lion at Mawnan Smith, near Trebah, during the run-up to the D-Day embarkation in June 1944.
7,500 American servicemen of the 29th Infantry Division embarked at Trebah on 31st May 1944 bound for the Normandy beaches.
