She had a few minutes to wait and immediately picked up the radiophone and told Supreme Commander Gordon in New York that the sleeping gas machine had worked wonderfully and that the Tunnel thru the Air held in captivity thousands of the enemy's airships and planes. Almost before she had finished making her report, the Tel-Talk buzzed. She ran to it and was informed by the scouting planes that the largest fleet of planes ever seen was approaching from the West and Northwest. Knowing that this was a combined fleet from the enemy's Western lines, from the same direction as the final one that attacked New York City. This was to be the supreme test. The first formation approached with about 1000 planes. Swiftly and silently, the gas machine did its work and they went down into the Tunnel. Then came the second, third, and fourth formation and so on. More than 50,000 planes had gone down and not more than one hour's time had elapsed. When it was over with, Edna realized that she had not been a human being during this ordeal, that she had worked just like the machine, forgotten everything but the responsibility for the protection of her country. When she knew that the Capitol of her beloved country was safe and that more than 50,000 of the enemy's airships were safely suspended in the Tunnel thru the Air and that the aviators had entered upon their seven days' sleep, she was supremely happy because not one life was required to save the Capitol. It was the greatest victory of all history thus far and she knew what it meant to Supreme Commander Gordon and how this victory would be hailed with rejoicing all over the United States. It would relieve the tension which had existed for two years when every hamlet, town and city had feared every night that they might be attacked and destroyed by bombs from the enemy's planes. The news had been flashed to all the Departments and Army Headquarters. When the scouting planes reported that more than 50,000 planes had been captured in this attack and not one of them escaped, the President and Army officers breathed a great sigh of relief and knew that this meant certain victory for the United States because the enemy had concentrated their attack on New York and Washington with their best planes, and had very few large bombing planes left, and if this was not the end of the war, it was the beginning of the end.
