This plan, it is almost needless to remark, was unanimously adopted. But concerted action was necessary among all the groups, and in view of the “skull-cracking,” to use their own phrase, on the afternoon of May 3, a secret conference of all groups was determined upon as a supplement to Spies’ pronunciamento and as an incitement to future revolutionary movements. A notice understood by all in the armed sections—“Y, come Monday evening”—was inserted in the _Arbeiter-Zeitung_. The commander of the Lehr und Wehr Verein rented a beer basement at No. 54 West Lake Street, known to the followers of Socialism as Greif’s Hall, and along towards eight o’clock representatives of all the armed sections of the Internationale gathered there. In order that the utmost privacy might be maintained, guards were posted both at the front and rear entrances with instructions to permit no one to stand on the outside and to admit only trusted adherents. When the session opened there were between seventy and eighty members of the various sections present. Their deliberations were presided over by Gottfried Waller, who subsequently became an important witness for the State. Spies’ “Revenge circular,” written late that afternoon, was distributed in the meeting, and its sentiments were heartily seconded by all present. Engel finally submitted the plan already given, and some discussion followed, participated in by various members. Fischer considered the plan admirable, and, lest there might be evidence of weakness, he stated that if any man acted the part of a coward, his own dagger or a bullet from his rifle should pierce that man’s heart. Inquiries being made with reference to a supply of bombs, he suggested that the members manufacture them on their own account. The best thing, he said, was to procure a tin coffee-bottle, fill it with benzine, attach a cap and fuse, and they would have a most effective bomb. Engel’s plan went through with a rush. Having now agreed upon a definite course, it was necessary to adopt a signal to warn the sections of danger and summon them to action. Fischer was equal to the occasion. He proposed the German word “Ruhe,”—signifying “rest” or “peace,”—and added that whenever it should appear in the “Letter-box” column of the _Arbeiter-Zeitung_, all would know that the moment for decisive action had been reached, and that all were expected to repair promptly to their appointed meeting-places, fully armed and ready for duty. The suggestion was adopted.
