But perhaps the most dramatic of all the intercepted messages (except the Luxburg and Zimmerman notes, of which the story cannot yet be told) were those which revealed the part played by well-known Irish-American leaders in the ill-fated Casement revolution in Ireland. The story of the Casement expedition is too familiar to need to be retold. And comment upon the political morals of Justice Cohalan and John Devoy becomes superfluous in the light of these messages. American citizens (one of them signally honoured with public office in New York), both held their Irish blood superior, in their duty of loyalty, to the United States, using their citizenship as a cloak under which to strike at Great Britain, which has been for a quarter century the chief bulwark of this country against Germany’s plan to conquer us and to impose upon our country the most hateful tyranny in the history of the world. CHAPTER VIII THE TIGER OF BERLIN MEETS THE WOLF OF WALL STREET Franz Von Rintelen was the German tiger who missed his spring. He was the most powerful, the most dangerous, agent of the Kaiser in the United States: and to-day he nurses his hatred of us behind prison bars. But he did not retire to confinement until after our Government completed an extremely difficult and tedious investigation that was made necessary by his care in concealing the insidious work of propaganda and destruction in which he had engaged. Rintelen was a tiger in the implacable hatred he bore this country and in the ferocity with which he carried that hatred into action. Sent to America in 1915 to hinder the shipment of munitions to the Allies, he sought first to poison the press, then to corrupt labour, and, not content with these things, he finally tried to hire thugs to burn, to dynamite, and to assassinate, where other persuasions failed; and he did succeed in setting fire to thirty-six ships at sea, causing millions of dollars of loss, and imperiling hundreds of human lives.
