Luxburg's dispatches, when made public, led to uprisings against the Germans, making it impossible for him to remain in Argentina. The day the Count got his passports, September 12, 1917, "Doctor Brecht" had left the Bismarck restaurant and was on his way home with a German acquaintance when they saw a fire in the distance, and found the German Club was burning. It had been mobbed and set on fire by pro-Ally students and others. Seeing the club half destroyed, the Doctor and his companion returned to the Bismarck to inform their confreres. But they found that the restaurant had been completely gutted by a mob, the tables and dishes smashed, and every portrait of the Kaiser, Hindenburg, and other "heroes" slashed to pieces. Germany had been astonished a few months before by the publication of Foreign Minister Zimmerman's note to the German Minister in Mexico, proposing an alliance of Germany and Mexico to make war against the United States. There was nothing the Germans guarded more closely than that. Yet before Bernstorff reached Europe, that secret dispatch was published, and the first thing the German Ambassador to Sweden demanded to know when the Count reached Christiania, was how the Americans ever managed to get hold of it. The Foreign Office was stunned. Not only had its plot been exposed, but the exposure had shown that the Allies could decipher the most secret and puzzling code they could devise. Captain von Papen, who once called us "those idiotic Yankees," might have told them that we were more alert than he had supposed, for the exposure of his dealings in every detail; of the activities of Wolf von Igel, his aide; of Doctor Albert, of Fritz von Rintelen; of the ship-bomb plots; the plan to blow up the Welland Canal locks, and various other German intrigues, must have by that time convinced him that the Americans had some secret service of their own. When, on December 4, 1915, our Government demanded the recall of Papen, who was military attaché of the German embassy, and Captain Boy-Ed, the naval attaché, it was merely stated that the cause was "improper activity in military matters." Both protested, declaring that they had done nothing illegal. But later we published a full account of Papen's activities, with photographs of his checks, the exact amounts paid to his tools who did the dirty work, to whom they were paid and for what purpose. It was shown that Boy-Ed had transactions amounting to millions with German steamship lines whose officials were, through false manifests, sending out ships laden with coal and other supplies for German raiders.
