When Brietung asked Siebs to buy him some chlorate of potash Siebs was delighted at the opportunity to make some money and immediately undertook the commission. He had been instructed to get a small amount, perhaps 200 pounds. He needed money so badly, however, that he was very glad to find that the smallest kegs of the chlorate of potash were 112 pounds each, and he ordered three kegs. He paid for them with money supplied by Brietung and took a delivery slip. Ultimately this delivery slip was presented by Scholz who appeared one day with a truck and driver and took the chemical away.
Fay and Scholz made some experiments with the chlorate of potash and Fay decided it was not strong enough to serve his purpose. He then determined to try dynamite. Again he wished to avoid suspicion and this time, after consultation with Kienzle, he recalled Bronkhorst down at the Lush Sanatorium in New Jersey. Bronkhorst, in his work as superintendent of the grounds at the sanatorium, was occasionally engaged in laying water mains in the rocky soil there, and for this purpose kept dynamite on hand. Fay got a quantity of dynamite from him. Later, however, he decided that he wanted a still more powerful explosive.
Again he applied to Kienzle, and this time Kienzle got in touch with Siebs direct. By prearrangement, Kienzle and Siebs met Fay underneath the Manhattan end of the Brooklyn Bridge, and there Siebs was introduced to Fay. They walked around City Hall Park together discussing the subject; and Fay, not knowing the name of what he was after, tried to make Siebs understand what explosive he wanted by describing its properties. Siebs finally realized that what Fay had in mind was trinitrotoluol, one of the three highest explosives known. Siebs finally undertook to get some of it for him, but pointed out to him the obvious difficulties of buying it in as small quantities as he wanted. It was easy enough to buy chlorate of potash because that was in common commercial use for many purposes. It was also easy to buy dynamite because that also is used in all quantities and for many purposes. But trinitrotoluol is too powerful for any but military use, and it is consequently handled only in large lots and practically invariably is made to the order of some government. However, Siebs had an idea and proceeded to act on it.
He went back to the Whitehall Trading Company, where he had desk room, and saw his fellow occupant, Carl Wettig. Wettig had been engaged in a small way in a brokerage business in war supplies, and had even taken a few small turns in the handling of explosives. Siebs had overheard him discussing with a customer the market price of trinitrotoluol some weeks before, and on this account thought possibly Wettig might help him out. When he put the proposition up to Wettig the latter agreed to do what he could to fill the order.
In the meanwhile Fay had sent another friend of Brietung’s to Bridgeport to see if he could get trinitrotoluol in that great city of munitions. There he called upon another German who was running an employment agency—finding jobs for Austro-Hungarians who were working in the munitions plants, so that he could take them out of the plants and divert their labour from the making of war supplies for use against the Teutons. The only result of this visit was that Brietung’s friend brought back some loaded rifle cartridges which ultimately were used in the bombs as caps to fire the charge. But otherwise his trip was of no use to Fay.
Carl Wettig was the weak link in Fay’s chain of fortune. He did indeed secure the high explosive that Fay wanted, and was in other ways obliging. But he got the explosive from a source that would have given Fay heart failure if he had known of it, and he was obliging for reasons that Fay lived to regret. Siebs made his inquiry of Wettig on the 19th of October. The small quantity of explosives that he asked for aroused Wettig’s suspicions and as soon as he promised to get it he went to the French Chamber of Commerce, near by, told them what he suspected, and asked to be put in touch with responsible police authorities under whose direction he wished to act in supplying the trinitrotoluol.
From that moment Fay, Siebs, and Kienzle were “waked up in the morning and put to bed at night” by detectives from the police department of New York City and operatives of the Secret Service of the United States. By arrangement with them Wettig obtained a keg containing 25 pounds of trinitrotoluol, and in the absence of Fay and Scholz from their boarding house in Weehawken, he delivered it personally to their room and left it on their dresser. He told Siebs he had delivered it and Siebs promptly set about collecting his commission from Fay.
Siebs had some difficulty in doing this, because Fay and Scholz, being unfamiliar with the use of the explosive, were unable to explode a sample of it and decided that it was no good. They had come home in the evening and found the keg on their dresser and had opened it. Inside they found the explosive in the form of loose white flakes. To keep it more safely, they poured it out into several small cloth bags. They then took a sample of it and tried by every means they could think of to explode it. They even laid some of it on an anvil and broke two or three hammers pounding on it, but could get no result. They then told Siebs that the stuff he had delivered was useless. Wettig volunteered to show them how it should be handled. Accordingly, he joined them the following day at their room in Weehawken and went with them out into the woods behind Fort Lee, taking along a small sample of the powder in a paper bag. In the woods the men picked up the top of a small tin can, built a fire in the stump of a tree, and melted some of the flake “T. N. T.” in it. Before it cooled, Wettig embedded in it a mercury cap. When cooled after being melted, T. N. T. forms a solid mass resembling resin in appearance, and is now more powerful because more compact.
However, before the experiment could be concluded, one of the swarm of detectives who had followed them into the woods stepped on a dry twig, and when the men started at its crackling, the detectives concluded they had better make their arrests before the men might get away; and so all were taken into custody. A quick search of their boarding house, the garage, a storage warehouse in which Fay had stored some trunks, and the boathouse where the motor boat was stored, resulted in rounding up the entire paraphernalia that had been used in working out the whole plot. All the people connected with every phase of it were soon arrested.
Out of the stories these men told upon examination emerged not only the hideous perfection of the bomb itself, but the direct hand that the German Government and its agents in this country had in the scheme of putting it to its fiendish purpose. First of all appeared Fay’s admission that he had left Germany with money and a passport supplied by a man in the German Secret Service. Later, on the witness stand, when Fay had had time enough carefully to think out the most plausible story, he attempted to get away from this admission by claiming to have deserted from the German Army. He said that he had been financed in his exit from the German Empire by a group of business men who had put up a lot of money to back an automobile invention of his, which he had worked on before the war began. These men, so he claimed, were afraid they would lose all their money if he should happen to be killed before the invention was perfected. This tale, ingenious though it was, was too fantastic to be swallowed when taken in connection with all the things found in Fay’s possession when he was arrested. Beyond all doubt his scheme to destroy ships was studied and approved by his military superiors in Germany before he left, and that scheme alone was his errand to this country.
