Pearl
To Those Who Served.
At four o'clock on the morning of December 7, 1941, two U.S. Army signalmen switched on the radar at their station near the northern point of Oahu. They would be on duty until seven when a truck would take them back to the post for breakfast.
At 0702 an echo appeared on the oscilloscope such as neither man had ever seen before. It was large and luminous. They reasoned that something must be wrong with the equipment. By their calculations, a large flight of airplanes was 132 miles off Kahuku Point.
They followed the reflection to within twenty miles, where it was lost in a permanent echo created by the surrounding mountains. By then it was 0739.
The Japanese air attack on Pearl Harbor began at 0755, with almost simultaneous strikes at the Naval Air Station at Ford Island and at Hickam Field, followed by attacks on strategic points all over the island of Oahu.
Some of the Signal Corps officers on the island were on duty; others were alerted by the first wave of bombings; still others knew nothing of it until notified officially.
Word of the attack reached the Navy communications center in Washington at 1350 Sunday, Washington time, over the direct Boehme circuit from the Pearl Harbor radio station.
In an action message Admiral Husband E. Kimmel, the commander in chief of the Pacific Fleet, the broadcaster was saying, “Air attack on Pearl Harbor. This is not a drill."
