Arriving on the ground, they found the agitator right in the midst of his incendiary exhortations, that point where he was telling his Anarchist zealots that he had some resistance in him, and assuring them that he knew they had too. At that moment the police were ordered to halt within a few feet of the truck wagon, and Capt. Ward, advancing to within three feet of the speaker, said: “I command you, in the name of the people of the State, to immediately and peaceably disperse.” Turning to the crowd, he continued: “I command you and you to assist.” Fielden had meanwhile jumped off the wagon, and, as he reached the sidewalk, declared in a clear, loud tone of voice: “We are peaceable.” This must have been the secret signal,—it has about it suggestions of the word “Ruhe,”—and no sooner had it been uttered than a spark flashed through the air. It looked like the lighted remnant of a cigar, but hissed like a miniature skyrocket. It fell in the ranks of the second division and near the dividing-line between the companies of Lieuts. Stanton and Bowler, just south of where the speaking had taken place. A terrific explosion followed—the detonation was heard for blocks around. The direction in which the bomb—for such it was—had been thrown was by way of the east sidewalk from the alley. It had been hurled by a person in the shadow of that narrow yet crowded passageway on the same side of, and only a few feet from, the speaker’s stand. [Illustration: SERGT. (NOW CAPT.) J. E. FITZPATRICK.] The explosion created frightful havoc and terrible dismay. It was instantly followed by a volley of small fire-arms from the mob on the sidewalk and in the street in front of the police force, all directed against the officers. They were for the moment stunned and terror-stricken. In the immediate vicinity of the explosion, the entire column under Stanton and Bowler and many of the first and third divisions were hurled to the ground, some killed, and many in the agonies of death. As soon as the first flash of the tragic shock had passed, and even on the instant the mob began firing, Inspector Bonfield rallied the policemen who remained unscathed, and ordered a running fire of revolvers on the desperate Anarchists. Lieuts. Steele and Quinn charged the crowd on the street from curb to curb, and Lieuts. Hubbard and Fitzpatrick, with such men as were left them of the Special Detail, swept both sidewalks with a brisk and rattling fire. [Illustration: LIEUT. JAMES P. STANTON.]
