Only a trial flight--an experiment to test their controls! No need for me to try to tell you of the thoughts that tore me through and through while I struggled to bring my ship to an even keel in the hurricane of explosion that drove up at me from below. But I spat out the one word: "Brotherhood!" and I prayed for a place in the front line where I might send one shot at least against so beastly a foe. * * * * * That was somewhere in Massachusetts. Their foremost columns were close behind. They came to a stop some fifty miles from our waiting line of battle: I learned this when I got to Washington. And the reason, too, was known; it was published in all the papers. There had been messages to the President, broadcast to the world from an unknown source: "To the President of the United States--warning! This war must end. You, as Commander-in-Chief of the American forces can bring it to a close. I have prevailed upon the Red Army of the Brotherhood to halt. They have listened to me. You, also, must take heed. "You will issue orders at once to withdraw all resistance. You will disband your army, ground all your planes; bring all your artillery into one place and prepare to turn the government of this country over to the representatives of the Central Council. You will act at once." "This war is ended. All wars are ended forevermore. I have spoken." And the strange message was signed "Paul." The wild words of a maniac, it was thought at first. Yet the fact remained that the enemy's advance had ceased. Who was this "Paul" who had "prevailed upon the Red Army" to halt? And then the obvious answer occurred; it was a ruse on the part of the Reds. They feared to attack; their strength was not as great as we had thought--officers and men of all branches of the service took new heart and plunged more frenziedly still into the work of preparation. There were direction-finders that had taken the message from several stations; their pointers converged upon one definite location in southern Ohio. Over an area of twenty square miles, that place was combed for a sending radio where the message could have originated--combed in vain. * * * * * The next demand came at ten on the following morning. "To the President of the United States: You have disregarded my warning. You will not do so again; I have power to enforce my demands. I had hoped that bloodshed and destruction might cease, but it is plain that only that will save you from your own headstrong folly. I must strike. At noon to-day the Capitol in Washington will be destroyed. See that it is emptied of human life. I have spoken. Paul."
