About ten o'clock, a policeman in Worth Street, while endeavoring to clear the sidewalk, was knocked down and severely beaten. At length, breaking away from his assailants, he hastened to the central office in White Street, and reported the state of things. A squad of police was immediately dispatched to arrest the ringleaders. On reaching Centre Street they found a desperate fight going on, and immediately rushed in, to put a stop to it. The belligerents at once made common cause against them. A bloody hand-to-hand conflict followed, but the police at length forced the mob to retreat. The latter, however, did not give up the contest, but mounting to the upper stories and roofs of the tenement-houses, rained down clubs and stones so fiercely, that the police were driven off with only two prisoners. Comparative quiet was now restored, though the excitement spread in every direction. It lasted, however, only an hour or two, when suddenly a loud yell was heard near the Tombs, accompanied with the report of fire-arms, and crowds of people came pouring down Baxter and Leonard Streets, to get out of the way of bullets. Some wounded men were carried by, and the utmost terror and confusion prevailed. The air was filled with flying missiles and oaths, and shouts of defiance. Now the Dead Rabbits would drive their foes before them, and again be driven back. The bloody fight thus swayed backwards and forwards through the narrow streets for a long time. At length twenty-five Metropolitan Police appeared on the scene, while fifty more were held in reserve. Though assailed at every step with clubs and stones, they marched steadily on, clearing the crowd as they advanced, and forcing the Dead Rabbits into the houses, whither they followed them, mounting even to the roof, and clubbing them at every step. After clearing the houses, they resumed their march, when they were again attacked by the increasing crowd, many of them armed with muskets and pistols. Barricades were now erected, behind which the mob rallied, and the contest assumed the aspect of a regular battle. The notorious Captain Rynders came on the ground, between six and seven o'clock, and attempted to restore quiet. Not succeeding, however, he repaired to the office of the Police Commissioners, and told Commissioner Draper, if he had not police force enough to disperse the mob, he should call out the military. The latter replied that he had made a requisition on Major-General Sandford, for three regiments, and that they would soon be on the ground. But it was nine o'clock before they made their appearance. The police then formed in two bodies of seventy-five men each, and supported, one by the Seventy-first Regiment and the other by the Eighth, marched down White and Worth Streets. This formidable display of force overawed the rioters, and they fled in every direction. This ended the riot, although the military were kept on duty during the night.
