The whole United States was waiting in anxiety because it was known that within a few days the armistice would end and the United States must either fight or surrender. The people in Washington, Boston, Philadelphia, and New York had not slept for more than a week. They knew that an air attack had been threatened and feared the consequences. Supreme Commander Gordon dispatched the sleeping gas by "Marie the Angel of Mercy," and it was distributed to the planes all across the country. Colonel Kennelworth returned at the end of the second day in "Marie the Angel of Mercy," after distributing the sleeping gas and giving instructions how to use it. The "Demon of Death" was tested out and found to be in good working order. For many months previous to this, all of the large cities had been kept in darkness because they feared night attacks. CHAPTER XXX When the commanders of the Allied Enemy in Chicago and St. Louis received the defiance hurled at them on October 15, 1931, this reply was signed by Supreme Commander Robert Gordon. The English, German, Austrian, and Russians had never heard of this United States officer before and were at a loss to understand whom the United States had placed in supreme command. The reply was conveyed to Japanese and Spanish headquarters in Mexico and the Japanese quickly understood just who Supreme Commander Robert Gordon was and feared that he had made some wonderful invention which had made him confident of winning the war. The Japanese Generals, knowing what this might mean and fearing the great genius, Robert Gordon, asked for an allied war council to convene before making another attack. On October 21st it was decided that the War Council should be held in the City of Mexico. The allied enemy were confident that the United States would not make any attack in the near future, but would wait for them to make the next move. They felt that the great losses which had been suffered by the United States Army at the battle of Chicago placed them in no position to make an immediate attack and that they would try to strengthen their position for the next attack by the allied enemy. It was decided that the commanding generals of all the allied enemy nations should proceed at once to the City of Mexico to hold a council and decide what the wisest and next move should be. They left in the dead hours of the night in the fastest planes and those which could rise to the highest altitudes, enabling them to travel noiselessly and at a height at which they could not be detected or captured. The scouting and cruising planes were left to patrol the lines between Chicago, St. Louis and New Orleans and watch for any move that might be made on the part of the United States forces.
