"1.54. From Twenty-first. Send military assistance immediately to First Avenue and Twenty-eighth Street. The mob increases, and will murder the military force."

Ans. "They are on their way up."

They soon arrived, and were at once furiously attacked by the mob. The soldiers fired into them, but they boldly held their ground, and were evidently bent on a desperate fight.

The former now took up their stations at the junction of the streets, and were about to sweep them with canister, when from some cause a delay was ordered. This increased the boldness of the mob, and they taunted and derided the soldiers. But in a few minutes a reinforcement of regulars arrived on the ground and charged bayonets. The rioters fell back, but rallying, forced the soldiers to retire in turn. The latter, however, returned to the charge, when the mob again gave way, but still stubbornly refused to disperse.

News of the magnitude of the struggle reached the Seventh Regiment, and they rapidly marched to the spot. Their steady tramp along the pavement, and well-set ranks, discouraged the crowd, and they marched and counter-marched through the streets without molestation.

The mob, however, dispersed only to reassemble again in Twenty-ninth Street, and began to plunder the stores in the vicinity, and spread devastation on every side.

This being reported to head-quarters, a military force was despatched to disperse them. The rioters, however, instead of retreating, attacked them with the greatest fury. Almost every house was filled with them, and they lined the roofs with muskets and pistols, from which they poured down a deadly fire. For nearly a half an hour the fire was kept up without cessation, and many were killed. A sergeant was knocked down by a brick-bat, and then seized and beaten to death. The troops finding themselves unable to dislodge the assailants, retreated, leaving the body of the sergeant in the street, where it lay for three hours. General Brown not having a sufficient number of troops on hand, the mob all this time had it their own way. It was nine o'clock before he could despatch Captain Putnam with a strong force to put an end to the disgraceful scene. Arriving on the spot, the latter addressed the crowd, saying that he had come to carry away the dead body of the sergeant, and should do it at all hazards. But he had hardly placed it in a wagon, when the crowd began to assail his troops. He immediately unlimbered his pieces, when it scattered in every direction. But the rioters came together again at the corner of Thirty-first Street and Second Avenue, where they were met by reinforcements, and made a stand. They filled the houses, and mounted to the roofs, armed with muskets and revolvers, and as Putnam appeared, commenced a rapid fire. Placing his pieces in position, this gallant officer swept the street with canister, which soon cleared it. Eleven of the ringleaders were shot down, and bodies lay thick on the pavement. But this did not intimidate those in the windows, or on the roofs, and they kept up a steady fire. Putnam, who showed by his cool courage that the fighting stock from which he came had not degenerated, now ordered his men to turn their fire on the buildings. At each discharge, the heavy volleys brought down many of the wretches, some pitching headlong from the roof, and dashing out their brains on the pavement and flagging below. But the fight was very unequal, for the assailants would expose their bodies as little as possible; Putnam saw that the houses must be stormed, and gave the order to do it. The fight was now transferred to the inside, and became close and murderous. In the narrow halls and on the stairways, numbers were of no avail, and the rioters fought with a desperation they had not before exhibited. There was no way of escape, and they seemed to prefer death to being taken prisoners, and for a half an hour maintained the conflict in the darkened rooms and passages with a ferocity that was appalling. At last, however, with their numbers sadly thinned, they were forced to yield, and took refuge in flight. Many, unable to get away, hid under beds and in closets, but the soldiers ferreted them out, and carried them to police head-quarters.

The arsenal had not been attacked, as Sandford seemed every day to think it would be. Many colored people, as before stated, took refuge in it; and about noon on this day, a body of police arrived before it, with the children of the Colored Orphan Asylum that had been burned on Monday, in charge. They had since that time been scattered round in station-houses, but were now to be escorted to Blackwell's Island, for better security. It was an impressive spectacle this army of children presented, as they drew up in line in front of the arsenal to wait for those within to join them. The block was filled with them. The frightened little fugitives, fleeing from they scarce knew what, looked bewildered at their novel position. It seemed impossible that they ever could have been the objects of any one's vengeance. With a strong body of police in front and rear, and a detachment of soldiers on either side, they toddled slowly down to the foot of Thirty-fifth Street, from whence they were taken by boats to the Island.

The Sixty-fifth New York Regiment arrived from Harrisburg in the afternoon, and just before midnight the One Hundred and Fifty-second also reached the city, and marched up Broadway to police head-quarters, where they were stowed away to get some rest.

A heavy storm that set in during the evening, helped to scatter the crowd that would otherwise have gathered on this warm July night, but it at the same time gave a sombre aspect to the city. The crescent moon was veiled in black, and thunderous clouds that swept heavily over the city, deepened the gloom, and seemed portentous of greater evil. The closing of all the stores and shop-windows at nightfall, through fear, left the streets lighted only by the scattering lamps. This unusual stretch of blank dead walls, emitting no ray of light, rendered the darkness made by the overhanging storm still more impenetrable. Flashes of lightning would reveal small groups of men bent on plunder, in sections where the military and police were not stationed, but no open violence was attempted. In other directions, the bayonets of the soldiers would gleam out of the dense shadows, as they silently held the posts assigned them, ready to march at a moment's notice. This was the fourth night, and the cannon planted in the streets, and the increased military force, showed that peace was not yet fully restored. The Seventh Regiment was quartered in Thirty-fourth Street, part of the soldiers within a building, and crowding every window to catch the first sign of disturbance, and part stationed below, or marching back and forth in the street. Other troops and policemen were massed at head-quarters, ready to move, at the word of command, to any point threatened by the mob.
