Schleindl’s zeal had led him into other channels of German activity. At college in Germany he had had a friend named Alexander Dietrichens, later known variously as Willish, Sander, Glass, and Lizius--one of those Riga Russians of German parentage who have served Bolshevism so eminently in Russia. In 1915 Dietrichens was in America, and the two renewed their friendship. He said he was eager to serve the Fatherland, and that he only wanted to know who was supplying munitions to the Allies to start a campaign of destruction against them. He suggested the Du Pont factories at Wilmington, and asked the young bank clerk to come along. Schleindl, impressionable and emotional, had not the courage. He confessed to me that he wept at the thought, and that he asked Dietrichens whether any harm could come to him if the explosion killed anyone. “Very likely,” Dietrichens answered cheerfully. Schleindl then declined, but he helped the dynamiter to the extent of keeping an occasional bomb or a package of dynamite for him during the day in his locker or under his desk at the bank. The main cache where Dietrichens stored his explosives was near Tenafly, New Jersey, but when Schleindl and I visited it, in a deserted spot almost a mile from the nearest building, the shanty was empty. Schleindl was tried, convicted and sentenced to an indeterminate term in the penitentiary, for the theft of documents. Koenig pleaded guilty to the charge, but sentence was suspended on him owing to the greater importance of the Welland charges. The Schleindl and Dietrichens cases are only two examples of many to which the little black book gave clues. It suggested investigations into many others, for it was a real storehouse of names, and knowing Koenig’s close relationship with the highest German authorities in the United States, it contributed a large number of items to the bill of complaint against Germany which provoked the President’s Flag Day warning of 1916. Koenig’s mere mention of the name of “Horn” in D-Case 277 gave evidence of the German sponsorship of the attempt of Werner Horn to blow up the Vanceboro bridge in February, 1915; the name “Stahl” in D-Case 328 indicated by Koenig’s own hand that it was he who paid Gustave Stahl for the false affidavits that the _Lusitania_ had carried guns; the name “Kienzle” in D-Case 316 was the name of a man who was involved in trying to blow up vessels sailing for France and England; the name “Hammond” in D-Case 357 led to the disclosure that the Bureau of Investigation, although chiefly engaged in spying and destroying plots, sometimes ran other and more delicate errands for von Bernstorff.
