Early in the morning, the radar controls detected the presence of planes. The officer on duty, woken by the alarm, said: “Forget it,” but then, 183 Japanese planes rushed to the Pearl Harbor naval base, which was left almost unguarded. Later, a “second wave” came, it met some resistance but it was too late. Oklahoma, Arizona and others: 15 US ships and 272 US aircraft were damaged. But on December 6, the US Department of Defense deciphered the Japanese code and knew about Japan’s intentions! Without much care about urgency, the Department sent a normal telegram to Hawaii. But it was Sunday… The telegram came only on December 8, when Franklin Roosevelt called the day before “The Day of Infamy.”
