On the night of November 19th, 1931, the Supreme War Council which had convened in Mexico City broke up and the commanding generals returned to their various posts around St. Louis and Chicago. Supreme Commander Gordon had his powerful Tel-Talk directed so that he would get all the conversation along the lines between Chicago, St. Louis and New Orleans. When he went to his headquarters in Detroit on the morning of November 20th, he went in to look at his Tel-Talk, saw that there had been a conference of the enemy held the night before. He pushed the needle of the machine back and turned it on; put his ear to the receiver and listened. He found that the commanding generals had talked over the conference in Mexico and had now decided that their next attack would be on Detroit in order to destroy the factories there and prevent the United States continuing making airplanes and inventions which might help them to win the war. He was very happy to get the plans of the enemy. It was just what he wanted. He was anxious to test the Tunnel thru the Air, capture the enemy's planes and keep them there because he knew when once he got them in the Tunnel, they would be unable to get out of it and he could keep them suspended in the air indefinitely, moving up and down in the Tunnel, or could capture them and destroy them. He was impatient and anxious for an attack upon Detroit and decided to defy the enemy and urge them on. With the plans of the enemy in his possession, Supreme Commander Gordon decided to change the location of the Tunnel machines so as to protect the factories and large buildings in Detroit. He arranged the machines so that when the attacking planes came over Detroit at a high altitude, he could drop them into the Tunnel thru the Air and thus prevent any harm to the factories or buildings in Detroit. He waited patiently for an attack upon the city, but no move of any kind was made by the enemy. When it was near Thanksgiving, he had a great desire that the battle should start around that time so that the United States might have the greatest Thanksgiving in history because he was confident that if the attack came, Detroit would be successfully defended and the enemy for the first time would find that we had outwitted them. He decided to urge the enemy to make an attack on Detroit as soon as possible, so ordered a large electric sign built with letters twenty feet high, "DETROIT IS READY--WON'T YOU COME AND TAKE US WE WANT TO BE YOUR THANKSGIVING TURKEY." The sign was placed on an airplane and lighted. This plane passed in full view of the enemy's lines at St. Louis and Chicago. What the enemy thought of this, perhaps no one will ever know. Colonel Manson later wrote that this electric sign put the fear of God in the heart of the enemy; that the Germans recalled the days when the Yankees arrived at the time of the great World War. The Japanese, the Spanish and the English realized that this was not meant for a bluff
