For a long time they swayed backward and forward, apparently without any definite purpose, and moved only by the spirit of disorder that had taken possession of the city. But about two o'clock, these various bodies began by mutual attraction to flow together, and soon became one immense mass, and impelled by some information or other, gathered threateningly around a large mansion on the corner of Forty-sixth Street and Fifth Avenue. They had supplied themselves with all sorts of weapons, revolvers, old muskets, stones, clubs, barrel-staves--in short, everything that could be found, that might be of service in a fight--and soon commenced plundering the residence. But their movements had been telegraphed to head-quarters, and Captain Walling, of the Twentieth Precinct, was dispatched thither, with a company of regulars under Captain Putnam, a descendant of "Old Put." The report soon spread through the crowd, that bayonets could be seen coming up the avenue. Marching up to Forty-sixth Street, the force turned into it, towards the Fifth Avenue; and breaking into the charge step, with the order "no prisoners" ringing in their ears, struck the mob almost in the centre, cutting it in two, like a mighty cleaver. There was no need of bayonets--the police, at the head of the military, went right through it, and scattered the men in every direction. The force then divided into squads, and each one taking a section of the mob, followed it up on a swift run, and smote them right and left for several blocks. The larger portion went down Sixth Avenue, and seeing only a portion of the police pursuing, turned and showed fight, when the leader received a bullet in the head and fell. Seeing their leader fall, the mob wheeled and took to their heels. Captain Walling in one instance saw a crowd with fire-arms standing in an alley-way. Just then a fire-engine and company came down the street, and he with his small force got behind it, and kept concealed until opposite the unsuspecting crowd, when, with a shout, they dashed on it. A volley received them,--with answering volley, the police charged into the narrow opening. The rioters fled into a tenement-house, from which came yells and screams of terrified women and children. Walling had some sharpshooters with him, to pick off those beyond the reach of the clubs. One fellow, armed, was seen astraddle of the ridge pole of a house. The next moment a sharpshooter covered him, and he tumbled headlong to the ground. The same afternoon he saw some twenty or thirty men attempting to stave in a hardware store, evidently after pistols. Walling charged on them alone, and with one terrible blow, his club sent the leader to the pavement with his brains oozing out.
