Use of Intelligence in WWII

This is an excerpt from the paper...
The Normandy Invasion signaled the beginning of the liberation of Europe from the grip of the Nazis in World War II, and the Allied offensive was aided by intelligence gathered by the codebreaking unit known as Ultra and by the use of the Germans' own Enigma code machine. Ultra was an umbrella code name given to the intelligence gathered by the use of the Enigma machine. Both the British MI-6 and the American OSS had uncovered many of Hitler's secrets through conventional intelligence and espionage channels, but there were two sources of secret intelligence that were unconventional. One was called Ultra and was derived from the interception and decryption of secret German wireless transmissions. Ultra made an important contribution to the end of World War II, and the name remained a classified secret until 1974 when former Group Captain F.W. Winterbotham of the Royal Air Force, who had been in charge of security and the dissemination of the information gleaned by Ultra, was allowed by British authorities to complete a memoir and mention Ultra for the first time. The name Ultra was used because it had once been the name of the old Admirals' code at Trafalgar, and it would now be used by the British and the Americans to refer to intelligence of the highest order derived from cryptanalysis. Ultra has been described by some as being the reason the Allies won the war, but this overstates the case. The Normandy invasion is a good example of the value of U

ULTRA
As noted, Bletchley had housed the cipher unit since the 1920s, and the staff increased from about 120 to nearly 7,000 by 1944. The staff consisted primarily of men and women recruited from universities. This staff developed sophisticated methods and machinery, including the first operational electronic computer. They were also able to develop the intelligence known as Ultra:
The value of the resulting Ultra was all the greater because the enemy states remained unaware of the British success. The main reason for this was that they did not allow for the sophistication of the British attack when constructing and using their ciphers. Hardly less important, however, was the fact that the British took immense pains to avoid arousing enemy suspicions, imposing strict secrecy on the Ultra production process and strict regulations against carelessness in the distribution and use of Ultra intelligence. These precautions continued long after the war.
The secrecy accorded Ultra showed how important it was to the Allies. Ultra furnished intelligence that was better than any that had been achieved throughout history:
It was more precise, more trustworthy
